Why Custom EVA Cases Matter More Than Just “Packaging”
A well-engineered EVA case is part of your product, not an accessory. It determines how safely your product travels, how premium it feels in the consumer’s hand, and how many claims or returns you avoid over a product’s lifecycle.
For electronics, medical kits, tools and premium accessories, the case is the first physical touch-point between your brand and the end user. If the case feels cheap, flimsy or poorly fitted, users will question the quality of the device inside—even if the device itself is excellent.
Poorly designed EVA cases often lead to cracked plastics, scratched surfaces, broken tools, lost accessories and damaged cables during shipping. This turns into extra customer service workload, negative reviews and pressure from distributors or retailers.
On the other hand, a custom-engineered EVA hard shell can combine rigid protection + soft interior + perfectly cut insert, ensuring that every component has its own secure position. It also gives your brand a solid, premium appearance on shelf, especially when combined with high-density fabrics, fine zipper work and clean logo applications.
If you are expanding into new markets or planning to upgrade your packaging, it is worth treating the EVA case as a small engineering project—not just a sourcing task.
Key Factors When Developing Custom EVA Cases
Choosing the right EVA case is a multi-variable decision. You need to align application, material stack, interior layout, protection level, MOQ, cost and lead time instead of focusing on only one single parameter like price or thickness.
Application & Device Fit
Different applications have very different requirements. A case for a stethoscope is not the same as a case for a multimeter, drone controller or cosmetic brush set. We start by mapping:
- What product(s) will be stored?
- How many components, and in which arrangement?
- Will users carry it daily, occasionally, or mainly use it for storage?
- Which channels: online shipping only, or also retail displays?
This determines the outer dimensions, proportion, handle type and interior layout concept.
Material Stack – EVA, Outer Fabric, Lining & Accessories
A professional EVA case manufacturer always thinks in terms of “material stack”:
- EVA foam: density, hardness (Shore C), thickness
- Outer fabric: polyester, nylon, RPET, PU leather or other textiles
- Lining: brushed tricot, velvet, lycra, jersey, molded fabric, mesh pockets
- Accessories: zipper, pullers, rubber logo, webbing handle, D-rings, shoulder straps
Below is a simple reference table you can use when discussing projects:
Typical EVA & Fabric Combinations for Different Applications
| Application Type | EVA Thickness (mm) | EVA Hardness (Shore C) | Outer Fabric Option | Lining Option | Typical Use Case |
|---|---|---|---|---|---|
| Small electronics | 3–5 mm | 60–65 | 600D Polyester / 300D RPET | Brushed tricot / velvet | Earbuds, HDD, power banks, routers |
| Professional tools | 5–8 mm | 65–70 | 1680D Polyester / Nylon | Brushed tricot / knit | Multimeters, wiring kits, measuring tools |
| Medical & diagnostics | 5–8 mm | 65–70 | Woven fabric + PU panel | Antibacterial knit (optional) | Diagnostic kits, instruments |
| Beauty & cosmetics | 3–5 mm | 60–65 | PU leather / twill fabric | Velvet / satin-like lining | Brush sets, cosmetic palettes |
| Outdoor & sports | 5–8 mm | 65–75 | Nylon / ripstop / RPET | Knit or mesh pockets | Action cameras, sports devices, goggles |
| Heavy-duty industrial | 8–10 mm | 70–75 | 1680D Polyester + piping | Harder knit / foam inserts | Power tools, calibration devices |
Protection Level & Testing
EVA cases often need to balance several protection functions:
- Compression resistance during stacking or shipping
- Impact resistance against drops and knocks
- Scratch protection for sensitive surfaces
- Sometimes basic splash resistance or water repellency
We can support basic internal testing and, when necessary, guide customers towards third-party testing for drop tests, compression tests, IP ratings or transportation simulations.
Structure & Interior Layout
The interior layout is where a lot of value is created:
- Molded-in EVA cavities matching each component
- Die-cut foam inserts or CNC-cut foam with fabric lamination
- Mesh pockets for cables and manuals
- Elastic bands or straps for accessories
- Divider panels to separate kits or modules
A clean, intuitive layout improves user experience and makes reps or technicians work more efficiently in the field.
MOQ, Cost & Lead Time
Real projects must work under realistic constraints. We will discuss:
- Target order volume and phased quantities
- Cost targets per set or per kit
- Available timeline for first launch
- Whether we should start from an existing mold or create a new one
Flexibility on MOQ and tooling strategy is especially important for new brands, Kickstarter projects or new product categories.
Complete Material System for Custom EVA Case Engineering
Choosing the right materials for an EVA case requires understanding how EVA hardness, foam density, outer textiles, linings and accessories interact. We provide a systematic material framework designed to balance protection, weight, aesthetics and cost.
1. EVA Sheet – The Structural Core of Every Case
EVA foam determines 70% of the case’s structure, rigidity and protection level. Its characteristics include hardness, density, rebound rate, compression resistance and molding behavior.
Common EVA Specifications We Offer
| Property | Range / Value | Notes |
|---|---|---|
| Hardness (Shore C) | 55–80 | 60–65 for consumer goods, 70–75 for tools/industrial |
| Density | 80–120 kg/m³ | Higher density = better toughness and shape retention |
| Thickness | 3–10 mm | 3–5 mm portable kits / 6–10 mm protective or industrial |
| Color | Black, grey (standard), custom colors | Affects exterior visibility through fabric |
| Melt & Molding Performance | Standard / High stability | Important for precise cavity forming |
EVA Application Logic
- 60–65 Shore C → best for consumer electronics, beauty kits
- 65–70 Shore C → best for medical devices, professional instruments
- 70–75 Shore C → best for tools, industrial, heavy-duty outdoor cases
2. Outer Fabric Layer – The “Face” of the Case
Outer Fabric Options We Commonly Use
| Fabric Type | GSM | Key Features | Typical Applications |
|---|---|---|---|
| 300D Polyester | 180–220 gsm | Lightweight, economical | Retail, beauty, consumer goods |
| 600D Polyester | 240–300 gsm | Strong, stable, good abrasion | Electronics, tools, general-purpose EVA cases |
| 900D Polyester | 280–350 gsm | Structured, premium texture | Medical, professional kits |
| 1680D Nylon | 280–350 gsm | High abrasion, strong rigidity | Industrial tools, outdoor |
| Ripstop Nylon | 150–200 gsm | Tear-resistant, outdoor-friendly | Sports, action cameras |
| RPET Polyester | 200–300 gsm | Eco-compliant, recycled | Sustainability-focused brands |
| PU Leather | 0.6–1.0 mm | Premium, smooth, luxury | Beauty sets, premium kits |
Why Fabric Matters? The fabric defines brand perception, scratch resistance, water repellency and the level of premium feel. It also affects how well logos can be applied.
3. Inner Lining Materials – Protection for Sensitive Surfaces
Inner lining materials determine how your device interacts with the interior. Softness, anti-scratch performance and color stability matter greatly.
| Lining Type | Properties | Best For |
|---|---|---|
| Brushed Tricot | Soft, anti-scratch, smooth | Electronics, instruments |
| Velvet | Premium feel, delicate touch | Beauty, luxury goods |
| Jersey / Lycra | Stretchable, clean look | Sports, accessories |
| Mesh Fabric | Breathability, pockets | Cable storage, accessories |
| Anti-Bacterial Knit | Medical-safe | Healthcare kits |

Our Engineering-Based EVA Case OEM/ODM Solution
Developing a good EVA case is a process, not a single step. At Lovrix, we use an engineering-based workflow that connects fabric/webbing R&D, structure design, EVA molding partners, sewing lines and printing facilities into one coherent project.
Step 1
Project Brief & Application Analysis
We start with a structured project brief:
- Product category and application
- Target end-user and selling channels
- Quantity, target price, desired launch date
- Any special standards (medical, industrial, airline, etc.)
Our team will often ask extra questions to identify hidden needs you may not have fully defined yet, such as accessory expansion, spare parts, or labeling requirements.
Step 2
3D Structure & CAD Development
Based on your device dimensions or 3D files, we create:
- 3D case shape proposals
- CAD drawings for EVA mold outlines
- Interior layout sketches for cavities, inserts and pockets
This helps align everyone on the “architecture” before we cut any tooling or fabric. It also allows us to quickly spot potential issues like too-tight radii, zipper interference or insufficient interior height.
Step 3
Material & Fabric/EVA Selection
Next, we choose the right material stack:
- EVA thickness and hardness suitable for your protection and weight goals
- Outer fabric selection balancing cost, durability and brand aesthetics
- Lining selection based on surface sensitivity and cleaning needs
- Webbing and handle style according to carrying scenarios
- Logo execution: rubber patch, embroidery, printing, metal plate, etc.
We can provide swatch books and material photos, and for key projects, send physical fabric and EVA samples for your internal testing.
Step 4
Prototype & Fit Testing
We then move to prototype stage:
- Create a first round of molded EVA shells
- Assemble shells with outer fabric, lining, zipper and handle
- Check fit of all devices and accessories
- Evaluate opening angle, hinge feeling and user ergonomics
You receive physical samples to confirm: appearance, hand-feel, fit, structure, branding, and initial protection performance.
Step 5
Pre-Production Sample & Small Batch
Once the first prototype is approved, we build a more refined pre-production sample:
- Final fabrics, linings and zippers
- Correct logo positions and colors
- Updated internal layout or foam details
For some projects, we run a small pilot batch to validate production stability and internal QC processes before full mass production.
Step 6
Mass Production & Multi-Stage QC
During mass production, we implement:
- Incoming QC for EVA, fabrics, linings and accessories
- In-process QC checkpoints at cutting, molding, sewing and assembly
- Final QC on appearance, size tolerance, functionality, logos and packaging
- Random carton inspections before shipment
This reduces surprises when the goods arrive at your warehouse, fulfillment center or distributor.
Step 7
Packaging, Labeling & Logistics Coordination
Finally, we align packaging with your supply chain:
- Individual polybag, color box or custom packaging design
- Barcode labels, FNSKU labels or customer-specific stickers
- Carton markings and pallet configurations
- Coordination with your forwarder or assistance in choosing a shipping method

Complete Manufacturing Processes for Custom EVA Cases
A well-engineered EVA case requires precise thermal molding, fabric lamination, lining application, stitching assembly, trimming, branding, and packaging. Each step affects durability, appearance, dimensional accuracy and the case’s long-term performance.
1. EVA Thermal Compression Molding
Thermal molding is the core process that shapes EVA panels into a rigid shell structure. Proper molding ensures accurate curvature, consistent rigidity, smooth transitions, and shape stability.
Key parameters:
- Molding temperature: 140–180°C
- Pressure: 3–5 kg/cm²
- Cycle time: 20–60 seconds
- Mold type: CNC-machined aluminum molds
Why it matters:
- Determines shell sharpness and definition
- Impacts alignment between upper and lower shells
- Ensures consistent shaping across large production runs
- Strongly affects the perceived premium quality and stiffness
2. Fabric Lamination (Outer Shell Lamination)
The outer textile is bonded to EVA foam before molding. This creates a “fabric-EVA composite sheet” which is then shaped under heat and pressure.
Common lamination methods:
- Heat lamination – strong bonding, suitable for polyester and nylon
- Glue lamination – recommended for PU leather to avoid overheating
- TPU film lamination – adds waterproof or abrasion-resistant performance
Key considerations:
- Too high temperature may distort PU or surface texture
- Adhesive distribution must be uniform to avoid bubbles
- Fabric grain direction must be consistent for visual symmetry
3. Inner Lining Application
After molding, the interior of the case must be lined to provide anti-scratch protection and a clean appearance.
Lining methods:
- Full-surface lining – the entire inner wall is fully covered
- Selected-area lining – lining applied to key areas only
- Foam-laminated lining – for extra cushioning
- Sewn-in components – mesh pockets, elastic straps, divider panels
Quality checkpoints:
- Lining must be bubble-free and wrinkle-free
- Lining direction must be aligned (especially velvet/tricot)
- Adhesion must be stable under humidity and temperature changes
4. Sewing Assembly & Edge Binding
EVA shells are joined with zipper tapes and seam binding.
Processes:
- Stitch zipper path (upper & lower shell)
- Attach reinforcement tapes at stress points
- Apply binding tape around exposed edges
- Install internal pockets, straps, or organizers
Why it matters:
- Directly affects durability and case lifespan
- Prevents fraying, edge deformation, or burst seams
- Determines visual neatness and premium finish
5. Zipper Installation
Zipper quality affects usability more than many brands realize.
Zipper types:
- #5 nylon zipper – standard
- #8 heavy-duty zipper – tools/industrial cases
- Reverse coil zipper – sleeker appearance
- Waterproof zipper – outdoor use
Key QC criteria:
- Smooth opening/closing
- Accurate alignment of zipper ends
- No excessive curvature or tension along zipper path
6. Branding & Logo Technologies
Brand identity is applied after assembly. Lovrix provides all major branding methods:
| Logo Method | Characteristics | Best Use Cases |
|---|---|---|
| Rubber Patch | Rugged, modern | Tools, electronics, outdoor |

| Screen Printing | Cost-effective | Retail packaging, gift sets |
| UV Printing | High-resolution graphics | Small details, icons |
| Metal Plate | High-end feel | Premium or luxury kits |
7. Packaging & Final Quality Control
Before packaging, each case undergoes multi-point inspection:
- Appearance check: dents, bubbles, faulty lamination
- Dimensional accuracy: ±3–5 mm tolerance
- Shell rigidity test: compression/shape retention
- Zipper test: smooth run, no misalignment
- Branding check: correct color and position
- Packaging: polybag, color box, custom packaging

Our Experience & Representative EVA Case Projects
Lovrix has supported a wide range of EVA case projects across electronics, tools, medical, beauty and outdoor categories. We focus on combining correct protection with practical, manufacturable constructions that can scale.
Example 1 – Portable Electronics Diagnostic Kit Case
A European electronics brand needed a compact EVA case for a handheld diagnostic tool plus several probes and cables. Their pain points were tangled cables and damaged probes in shipping. We designed a molded EVA shell with 600D polyester outer fabric, brushed tricot lining, molded cavities for the main unit and probes, and a mesh pocket for cables. The result reduced cable damage and made field technicians much faster in setting up their equipment.
Example 2 – Medical Point-of-Care Device Case
A healthcare client required a travel case for a point-of-care diagnostic device. The inside needed both strong physical protection and a professional, hygienic appearance. We recommended 5–8 mm EVA at mid-hardness, a clean woven fabric outer, smooth knit lining and precisely cut foam to hold cartridges and accessories. The case passed internal transportation checks and gave their sales team a very professional demonstration kit.
Example 3 – Heavy-Duty Tool Kit EVA Case
A tool brand needed a multi-layer EVA case for meters, screwdrivers and small components. The biggest challenge was weight and repeated daily use. We used 8 mm EVA with higher hardness, 1680D polyester outer fabric, reinforced piping and a double-zipper design. Interior included foam inserts and elastic bands. The case is now widely used by field service technicians with very low claim rates.
Example 4 – Premium Cosmetic Brush & Palette Case
A beauty brand wanted a minimalist, high-end travel case for brushes and palettes. Here, aesthetics and touch-feel were more important than heavy-duty protection. We combined a thinner EVA profile with PU outer, soft velvet lining and a gold zipper, plus elastic slots for brushes. The final product worked well both as a gift set and as a retail SKU.

FAQ – EVA Case Manufacturing & Working with Lovrix
Below are some of the most common questions we receive from brands, importers and e-commerce sellers considering custom EVA cases.
Q1. What is your usual MOQ for custom EVA cases? For most projects, our standard MOQ is around 500–1000 sets per SKU, but we can offer lower quantities for first orders, pilot projects or high-value applications. The exact MOQ depends on mold complexity, material combinations and how many colorways or size variations are involved.
Q2. How long does it take to develop a new EVA case from idea to mass production? A simple project can move from concept to first sample in around 7–15 days, while more complex layouts may need multiple iterations. Once the sample is approved, typical mass production lead time is 30–45 days. If you have a fixed launch date, we will work backwards to build a realistic schedule.
Q3. Do I need to provide 3D files or can you design from physical samples? We can work in both ways. If you already have 3D files or detailed drawings, we will use them directly for mold and layout development. If not, you can send us physical products and a simple sketch of how you want them arranged. Our engineering team will create the necessary CAD and structure proposals for you to review.
Q4. How do you help choose the right EVA hardness, thickness and materials? We start by understanding your product weight, fragility, user scenario and shipping conditions. Based on this, we recommend one or more combinations of EVA thickness, hardness and outer fabrics, explaining the trade-offs in cost, weight and protection. You will receive both technical reasoning and, where possible, physical samples to evaluate.
Q5. What kind of logo and branding options are available for EVA cases? We can apply your branding through several methods: rubber patches, screen or transfer printing, embroidery, metal plates or debossed/embossed panels, depending on the outer material. We will suggest options that fit your brand guidelines, desired appearance and budget, while also taking long-term durability into account.
Q6. How is quality controlled during mass production? Quality is monitored at multiple levels. We inspect incoming EVA sheets, fabrics, zippers and accessories, then perform in-process checks during cutting, molding, sewing and assembly. Before shipment, a final inspection covers appearance, dimensions, functional details, branding and packaging. Inspection standards can follow our internal criteria or be customized to your own AQL requirements.
Q7. Can you support testing and certifications for my target markets? We can help coordinate relevant tests through accredited third-party labs, such as chemical safety, environmental compliance or performance-related tests. Before that, we will review your target markets and propose appropriate test items, so that you invest in meaningful testing rather than unnecessary ones.
Q8. What information should I prepare before asking for a quotation? To give you an accurate quotation, it helps to share product dimensions, number of components, rough layout idea, target quantity, target price range, preferred fabrics or appearance references and any special standards. Reference photos or links to similar products are also very useful. With more complete information, we can quickly provide realistic options.
Q9. How do you handle design confidentiality and brand protection? We treat your designs and product information as confidential and can sign NDAs if required. We do not show your branded products or molds to other customers, and internal access to project data is limited to staff directly involved. If you prefer neutral shipping marks or unbranded packaging, we can arrange that as well.
Q10. Can you combine EVA cases with other materials or products from your group? Yes. Because we also work deeply with fabrics, webbings, bags and printing, we can design integrated solutions such as EVA cases packed inside larger bags, matching fabric accessories, or coordinated packaging sets. This is especially useful for brands that want a unified look across multiple products or categories.
Develop Your Custom EVA Case with Lovrix
If you are planning a new EVA case project—or thinking about upgrading an existing one—the best starting point is a short, structured discussion. We will review your product, sales channels and protection needs, then propose a practical path forward including material options, layout ideas, cost scenarios and sampling plans.
You can send us:
- Product photos and dimensions
- A list of components to be stored in the case
- Any reference pictures or competitor examples you like
- Estimated quantities and target launch timeline
From there, we will prepare a tailored proposal and sampling schedule. Our goal is not only to produce your EVA case, but to make sure it works for your brand, your end users and your long-term supply chain.
