Designing a Custom EVA Case - What Our Engineers Want You to Know

When it comes to protecting your product, a well designed EVA case does more than just offer protection, it enhances the user experience, reflects your brand, and ensures your product stands out in the market.  At Yisi Packing, our engineers have years of experience in designing and manufacturing custom EVA cases for industries ranging from electronics to medical equipment.  Here’s what they believe every buyer should know before starting a project.

 

1. It Starts With Understanding Your Product

 

Our engineers always begin by asking:
What is the product’s size, shape, weight, and fragility?
Understanding these details helps us determine the right interior foam structure, case dimensions, and materials.  If your product has sensitive components or accessories, we’ll design separate compartments to hold each part securely in place.

 

2. Material Choice Matters

 

Not all EVA materials are created equal.  We select the EVA hardness case (usually measured in Shore 75), lining materials (such as velvet, nylon, or Lycra), and zipper types based on your specific needs.  For example, a high end electronics brand may require a smooth finish and luxury lining, while a tool case may prioritize durability and sturdy texture.

 

3. Custom Mold Tooling Adds Precision

 

One unique benefit of EVA is its moldability.  We create custom aluminum molds to produce the exact shell shape required. While there’s an upfront tooling cost, the precision and repeatability it offers are worth the investment, especially for large production runs.

 

4. Branding Makes a Difference

 

A custom EVA case is also a branding opportunity.  Our engineers work closely with clients to incorporate logos, colors, and patterns via silk screen printing, embossing, or rubber badges.  This ensures your case not only protects but also represents your brand professionally.

 

5. Design for Efficiency

 

Finally, our team always designs with manufacturing and shipping efficiency in mind.  A smart case design can reduce packaging space, lower shipping costs, and speed up production.  That’s why involving engineers early in the process is essential.

How to Design a Custom EVA Case by an EVA Case Manufacturer

Many of our customers query us even though we set a MOQ of 500 pcs. But we are always willing to help startup businesses or well established companies even for a smaller quantity.  The reason behind this is that we want to help new customers become long term cooperative partners to get a win win business.

 

Apart from business prospects, we want to help more companies solve their EVA case development barriers in China.  We have heard many stories from some of our customers who had unpleasant experiences working with certain factories.  Some of them were actual manufacturers in China but lacked international trade experience.  Even worse, some were working with middlemen who claimed to be manufacturers but had no control over operations at their “partner factories.”  We hear these stories regularly, and it seems they never stop.

 

As an EVA protective case supplier, we design cases with our professional packaging solutions, backed by over a decade of experience working with different buyers and designers around the world.  We have made many different types of OEM EVA tool cases for various industries, such as EVA cases for medical devices, wholesale packaging, and more.

 

We can offer professional suggestions for foam inserts, logo applications, style, opening orientation, and much more.  We believe today’s factories should not only follow customer ideas to create a case but also use their own experience to offer useful options if they believe it can improve the functionality of the EVA case.  This is what we must do, and it’s the reason why we’ve maintained a loyal group of customers who continue to support us through the years.

 

We have already worked with many famous brands across different industries.  However, due to NDA agreements, we cannot disclose their names here.  If you have the chance to visit our showroom, we can show you some of the projects we’ve completed with those brands in the past.

 

Finally, we believe EVA case packaging is a great marketing tool in today’s market.  From an environmental protection perspective, the case can be reused, unlike other types of packaging (like printed gift boxes).  At the same time, the protection level and price point are relatively similar to other packaging types.  So why not try it?  It’s a simple way to stand out among your competitors.

 

If you have any concerns or queries, please reach out to us at info@packingyisi.com.  We offer free consultations and idea sharing.  Please feel free to contact us, we are more than happy to hear from you.

The Pain Point in Finding a Reliable EVA Case Manufacturer in China

When businesses all around the world look to China for EVA (Ethylene Vinyl Acetate) case manufacturing, they often expect high quality products at competitive prices.  However, the path to finding a reliable EVA case manufacturer can be more complex than you can imagine.

 

One of the biggest challenges is quality inconsistency.  While many manufacturers promise premium grade materials and craftsmanship, the reality is that quality control can vary greatly between suppliers.  Inconsistent stitching, poor zipper durability, substandard materials, or misaligned molds can turn a product launch into a customer service nightmare.

 

Communication is another critical barrier.  Time zone differences, language gaps, and a lack of responsive service often lead to delays, misunderstandings, and missed deadlines.  When you’re managing tight schedules and client expectations, these communication gaps can seriously impact your business.

 

Minimum order quantities (MOQs) and inflexible production processes are also common frustrations.  Many Chinese manufacturers prioritize large volume orders, making it difficult for small or mid size businesses to find partners willing to cater to their unique needs.  They will not keep their promise delivery schedule if they got some volume order in between your shipment.  They will serve their 'Big' customer first. 

 

Custom design limitations can further complicate things.  Companies looking for industry specific solutions, whether for electronics, medical devices, cosmetics, or tools, often struggle to find a manufacturer that can adapt to specialized requirements and still maintain efficiency and affordability.

 

That’s where Yisi Packing steps in as a game changer.

 

At Yisi Packing, we specialize in tailor made EVA case solutions for different industries, offering both flexibility and reliability. Our team works closely with clients to understand their specific needs, ensuring every case is designed to protect and present their products perfectly.  From concept to final product, we maintain rigorous quality control standards and transparent communication every step of the way.

 

Whether you're a startup looking for a small run of customized cases, or an established brand seeking scalable production without compromising on quality, Yisi Packing is equipped to deliver.

 

We believe that sourcing from China doesn’t have to be a gamble, with the right partner, it can be a powerful strategic advantage.

Tubes：

Aluminum tubes (with an epoxy or phenolic interior coating) excel in this regard: their impermeable barrier seals out moisture and air, preventing degradation of active ingredients. The squeezable tube design allows users to dispense small, targeted amounts, reducing waste and ensuring precise application. Aluminum tubes seal tightly after each use, minimizing pollution. Aluminum is recyclable, making it attractive to environmentally conscious consumers.

Plastic composite tubes (e.g., PE/EVOH/PE, with high barrier properties). Plastic tubes with flip-top caps are ideal for travel-sized face creams. Advanced plastic formulations, such as those with barrier coatings, now rival glass in terms of moisture and oxidation resistance.

Features: Excellent sealing, strong barrier properties (light-proof and anti-oxidation), lightweight and easy to carry, and a squeeze-type dispenser allows for hygienic and precise dosage control. The aluminum tube has a retro, cosmeceutical, and pure feel.

Applicable to: Day cream, night cream, hand cream, ointment, and other products requiring high hygiene standards.

Airless Pumps Jar：

Features: Utilizing the air pressure principle, the device allows for "outflow only, no inflow" to completely isolate the contents from air and bacteria, significantly protecting the freshness of the active ingredients. It's clean and hygienic, leaving virtually no residue and providing an excellent user experience.

Applicable to: Almost all high-end functional skin care products, especially those with extremely high requirements for ingredient activity.

Lotion Pumps bottle：

Material: Bottles are typically made of plastic or glass with a pump.

Features: Easy and quick dispensing, controlled dosage, and superior hygiene compared to wide-mouth bottles. However, this product may leave residue and come into contact with the air at the top of the bottle.

Useful for: Thinner lotions, moisturizers, body lotions, etc.

How to Clean Dropper Bottles Yourself A Simple 4-Step Guide

Cleaning cosmetic glass dropper bottles properly is key to keeping your serums, essential oils, and liquids free from contamination. Follow this quick 4-step process to ensure they’re spotless and safe for reuse.​
First, disassemble the glass dropper bottle—separate the rubber bulb, glass pipette, and bottle itself. Fill a bowl with warm (not hot) water and let all parts soak for 10–15 minutes. This loosens residue, oils, or dried liquids clinging to the surfaces, making them easier to clean.​
Next, disinfect with rubbing alcohol (70% isopropyl works best). Either submerge all components in alcohol for 5 minutes, or pour alcohol into the bottle and squeeze the bulb repeatedly to flush the tube thoroughly. Alcohol effectively kills bacteria and breaks down tough, stubborn grime that plain water would likely leave behind.​
After alcohol treatment, rinse all components with warm water to remove any alcohol residue. Then, air-dry them completely on a clean towel—laying them upside down helps speed up drying and prevents moisture buildup, which can lead to mold.​
For an extra layer of sanitization, use an infrared ozone sterilizer. Place the dry parts inside, run the machine according to its instructions (usually 10–20 minutes), and let it complete the cycle. Ozone and infrared light work together to eliminate even the tiniest pathogens, ensuring your dropper bottles are germ-free and ready for their next use.​
This straightforward routine keeps your dropper bottles in top shape, protecting your products and extending the life of your containers.

The All-Scenario Revolution of Period Panties Comfort, Leakproof, and Sustainability Leading Women’s Underwear Trends

 

Over the past years, menstrual underwear—also known as period panties—has evolved from a niche eco-friendly alternative to one of the fastest-growing segments in the global women’s lingerie market. In 2024, the global market value neared USD 680 million, with projections to surpass USD 1.5 billion by 2030, achieving a compound annual growth rate of 13% to 15%. Behind these numbers lies a growing awareness of women’s health, the rise of sustainable consumption, and continuous innovation in design and technology. Periods are no longer times to endure discomfort but moments that demand comfort, confidence, and self-care.

As the global Period Underwear OEM Suppliers and Wholesale market experiences rapid growth, more brands and distributors are recognizing the potential of this emerging segment. This has sparked a surge in demand not only from end consumers but also from businesses looking to capitalize on new market opportunities.

This shift first manifests in the most direct consumer needs: leak protection and comfort. Early menstrual underwear was viewed mainly as a supplement to disposable products, but increasingly women use it as their primary protection. Advances in leakproof technology are key: premium period panties feature organic cotton or bamboo fiber inner layers for fast absorption, super-absorbent cores locking in moisture, and waterproof, breathable outer layers. High-waist styles with extended back panels offer comprehensive security for overnight and heavy flow users. These functional innovations meet core period needs and lay the foundation for further product development.

Once leakproof concerns are addressed, comfort becomes the critical factor driving repeat purchases. Modern women continue to work long hours, exercise, and travel even during their periods, fueling demand for seamless period panties and high-stretch fabrics. These designs maintain a stable fit without rolling, shifting, or causing heat buildup. Brands are segmenting their offerings by scenario: commuter styles prioritize stability and invisibility, athletic styles emphasize elasticity and support, and nighttime versions focus on softness and high absorbency.

 

Beyond function, sustainability is reshaping the market. Reusable menstrual underwear significantly reduces waste compared to disposables, appealing to eco-conscious consumers. Certifications such as GOTS organic cotton and GRS recycled fibers have become core brand selling points and contribute to premium pricing. Sustainability is no longer a “nice-to-have” but a decisive factor influencing purchase decisions.

 

Expanding Multi-Scenario Applications Unlock Massive Market Potential

As consumers demand higher health and lifestyle standards, the use cases for period panties have expanded well beyond traditional menstrual protection. This category is rapidly evolving into a multi-functional, multi-purpose product, unlocking enormous market potential.

 

First is the postpartum recovery period. New mothers face extended discharge and intimate care needs. Traditional pads often cause discomfort and require frequent changes. Soft, highly absorbent menstrual underwear is an ideal solution, offering effective protection while minimizing skin irritation and improving comfort.

 

Next is light urinary leakage protection. With age or after childbirth, pelvic floor weakening leads to common minor leakage issues. Specialized leakproof underwear with high absorption and antibacterial fabrics helps women confidently manage daily challenges, significantly broadening the user base.

 

Third, the sports and fitness scenario. Many women worry about leaks during running, yoga, or gym workouts. High-stretch, seamless, quick-dry period panties have become the go-to choice for active women, combining leak protection with freedom of movement and comfort during intense exercise.

 

Additionally, travel and outdoor activities form another important application field. Disposable products are inconvenient to carry and dispose of, while quick-dry, easy-to-clean period panties provide an eco-friendly and practical alternative, meeting the needs of long trips and outdoor enthusiasts.

 

Bulk seamless period panties supplier

 

This cross-scenario functionality not only increases usage frequency but also shifts consumer perception of period panties from “menstrual protection” to “all-year-round functional underwear.” Brands are responding by developing richer product lines, expanding market space and growth opportunities.

 

The competitive landscape is currently divided into three main players. International leaders like Thinx and Modibodi have established global presence through premium design and sustainability narratives; regional brands such as NEIWAI and Bananain quickly capture younger markets by blending local aesthetics with functional innovation; meanwhile, numerous OEM & ODM Period Panties Manufacturers play a crucial role in the global supply chain, providing affordable entry points for emerging brands. Differentiated functional designs, unique aesthetic positioning, and sustainability credentials are key strategies for new entrants.

 

Looking ahead 5 to 10 years, menstrual underwear technology will trend toward thinner, faster-drying, and higher-efficiency absorption. Nano-fiber technologies are expected to significantly enhance comfort and dryness. The demographic will expand from the core 18–35 female group to include teenagers and older women. Cross-category integration will become more common, merging period panties with sports bras, swimwear, and protective underwear to create multifunctional garments. On the distribution side, Direct-to-Consumer (DTC) brands will leverage social media platforms like TikTok and Instagram to accelerate global expansion. For brands and wholesalers alike, 2025 to 2030 represents a golden window of opportunity to capture market share and innovate in this rapidly evolving industry.

What physical tests does the tube packaging have to undergo?

1.Thickness measurement

The precise thickness of each layer of a tube is fundamental to its performance. This test uses a micrometer or specialized thickness gauge to measure the actual thickness of each layer (from the inner barrier film to the outer printed layer), typically at five to ten points throughout the tube. The goal is to ensure compliance with design specifications.

2.Sealing performance test

Heat Seal Strength (Tube End): Tube ends are sealed using heat during the manufacturing process. This test measures the force required to tear the seal. It ensures that the seal will not crack during extrusion, transportation, and storage. Standards generally require a minimum strength to ensure reliability.

Torque Test (Tube End to Cap): This test evaluates the tightness of the connection between the tube end and the cap. A torque meter measures the force required to unscrew or tighten the cap, ensuring it is neither too loose nor too tight. Typical ranges vary depending on product type—cosmetic tubes may require 0.5-1.5 Nm.Positive/Negative Pressure Test: To simulate extreme conditions, the tube is subjected to positive or negative pressure in the seal. This can identify micro-leakages in the seal that may be missed by standard visual inspection.

3.Barrier performance test

Barrier performance is crucial for products susceptible to external influences like oxygen and light. 

Two key test types dominate this category:

Oxygen Transmission Rate (OTR): According to the standard, this test measures the amount of oxygen that passes through the tubing material over time. A low OTR is crucial for products like vitamin C serums or essential oils, as oxidation can reduce their effectiveness.

Water Vapor Transmission Rate (WVTR): According to the standard, this test quantifies the amount of moisture that migrates through the tubing. This is crucial for dry products (such as powdered skincare) or water-sensitive formulas, as excessive moisture can lead to clumping or microbial growth.

4.Mechanical strength testing

Compression resistance: This test simulates warehouse stacking, placing the hose under pressure for a week. This checks for deformation, collapse, or seal failure under sustained load.

Drop test: Tubes (empty and full) are dropped from various heights (e.g., 1 meter, 1.5 meters) and at various angles (vertical, horizontal, diagonal) to simulate an accidental drop. This test ensures there are no cracks, leaks, or cap detachments.

Flex resistance: The tube is repeatedly flexed, particularly at the shoulder (where the barrel meets the nozzle), until it breaks, typically over 10,000 cycles. This test assesses the durability of travel-sized hoses or products designed for portable use.

5.Extrusion performance testing

You know what? A user's experience with a product is largely tied to how easy it is to squeeze the stuff out and how clean the whole process is.Take those squeeze tests, for example. We use something called a texture analyzer to measure just how much force is needed to get the product out of the tube. The goal here is to make sure it's not a total nightmare to squeeze (because who wants to get all frustrated, right?). But at the same time, it shouldn't be so easy that you end up squirting out way more than you need.And it doesn't stop there. The testers also keep an eye out for issues like "rat tails." You know, those stringy bits that hang around after you've squeezed the tube? Or problems with uneven flow. These little things might seem minor, but they can lead to a whole lot of wasted product and just a generally crummy experience for the user.Now, when it comes to medicine tubes where you need to get the exact right dose every single time, things get even more serious. The consistency of how much comes out with each squeeze is checked super carefully.

EVA Case Customization 101 Design & Build Basics

Recently, one of our customers mentioned that it would be helpful for buyers if we could create a blog about Step by Step EVA Case Customization.  While this may seem like a basic topic for us, having produced various cases for decades, it can be very informative for buyers who may not have much experience in this area.

 

Please read the following information, which we hope will help you develop cases that meet your specific needs and are truly fit for purpose.

 

Outer Shell Material

 

Polyester and PU are commonly used as outer materials for EVA cases.  This is because the outer covering must have enough elasticity to stretch.  If not, the material may wrinkle or become defective in certain areas.

 

As a professional case manufacturer, we provide guidance if our buyers choose their own outer shell material.  It's important that the selected material fits the intended purpose.

 

One example: A customer wanted to use PU for a protective case for measuring tools.  While PU gives a premium, leather like feel, we advised against it.  His case was meant for use in extreme construction environments, where durability was critical.  We suggested 1680D Polyester instead, which is more robust and suitable for such conditions.  He agreed, made a sample, and sent it for durability testing.  As expected, it passed.  He was very pleased with the outcome, otherwise, there could have been complaints from end users if the wrong material had been chosen.

 

Lining Options

 

The lining material depends on the type of device inside the case.  For example, velvet lining is suitable for optical or watch cases, as its soft, suede like texture helps prevent scratches.

 

In contrast, devices like medical equipment often require smooth, waterproof linings.  These cases must be easy to clean, especially if the inside gets dirty.  A suitable lining allows quick and simple maintenance.

 

Unfortunately, many manufacturers in China use tricot as a standard lining without much consideration.  They focus only on cost and production convenience, overlooking the practical use and potential side effects of using the wrong material.

 

Insert Options

 

Most of the time, we use die cut EVA inlays as a cost effective solution to hold your equipment securely.  However, if the shapes or styles of the items are too complex or not suitable for standard die cutting, we may recommend using an EVA molded tray or CNC foam insert instead.  Our solution will be based on the specific details and requirements you provide for your project.

 

Inside Pocket Options

 

Besides the main device, extra pockets are often needed for accessories.  Many buyers aren’t sure what kind of inner pockets are suitable.

 

As an experienced EVA case solution provider in China, we usually recommend mesh pockets with elastic bands if the accessories should be easily accessible and visibility isn’t a concern.  For accessories that need to stay secure or hidden, such as jewelry, we suggest polyester inner pockets with zippers to keep everything safe and in place.

 

Logo Options

 

For a simple, durable, and cost effective solution, debossed or embossed logos directly on the case are ideal.  However, if the logo has fine details or complex design elements, alternatives like woven labels, rubber patches, metal plates, or TPU embossed logos may be better.

 

We’ll recommend the best option to showcase your brand.  A well designed case isn’t just protective, it becomes a moving marketing tool throughout the product’s lifecycle.

 

Zipper Options

 

For office or kids’ products, we recommend regular nylon zippers for smooth and easy use.  For specific industries or functions, waterproof nylon zippers are necessary.

 

For instance, a customer developing a first aid kit case needed durability in extreme conditions.  We insisted on high quality, waterproof YKK zippers.  For life saving equipment, it's crucial that everything inside functions properly and stays protected.  As a responsible manufacturer, it’s our job to make sure your product performs reliably when it matters most.

 

Handle Options

 

Handle choices depend on the case's size and weight.  For large, heavy cases, we recommend webbing handles with plastic grip parts for comfort and durability.  For smaller, simpler cases, a basic webbing handle can help reduce costs.

 

We always use suitable components to match the purpose, ensuring our proposals stand out from other manufacturers in the market.

 

Accessories Options

 

Whether you prefer metal or plastic accessories, all components we use pass luggage grade loading and aging tests.  Whichever case you develop with us, you won’t need to worry about broken parts or user complaints, something we hear often from buyers working with low cost suppliers.

 

Many factories reduce costs by using cheap, stock accessories. Naturally, this affects the final product quality.  With us, you can be confident in what you’re getting.

 

Finally, we are happy to support your case development, no matter your industry.  Our goal is to provide reliable, long lasting products that keep your valuable items safe.
