EVA hard cases vs. alternative protective packaging
Custom EVA cases are chosen for medical, vial and instrument packaging because the material is moulded to the product outline and keeps its shape under load. The table below compares them with the usual alternatives.
| Option | Shock protection | Water resistance | Custom shape | Best for |
|---|---|---|---|---|
| Moulded EVA case | High | High — closed-cell foam | Yes — moulded to outline | Medical devices, vials, tools |
| Nylon / fabric pouch | Low | Low | Sewn, limited shaping | Soft goods, low-cost kits |
| Rigid PP or ABS box | Moderate | High | Needs a mould per size | High-volume standard sizes |
| Corrugated carton insert | Low | Low | Cut to size | Transit packaging only |
The sourcing route matters as much as the material: buying from the manufacturing factory vs. through a trading company affects unit cost, how the foam layout is tooled and how fast a revision can be produced. Jufeng Bag manufactures in-house in Xiamen, China.
How to place a custom order, step by step
The five steps below describe a standard OEM/ODM project. How to start depends only on how complete your specification is — a photo and a quantity are enough for a first quote.
- Step 1 — Send your requirement. Share a drawing, a reference sample or photos with target quantity and destination. You get a quotation and the exact MOQ back within 24 hours.
- Step 2 — Confirm price, MOQ and artwork. We fix the unit price for your quantity, cut the foam layout and confirm logo artwork. A 30 percent deposit starts production.
- Step 3 — Approve a pre-production sample. A sample is produced within 5 days. Nothing goes to bulk until you sign off on material, colour and foam fit.
- Step 4 — Bulk production and inspection. Production ships within 30 days after sample approval. A QC team of 8 people inspects 100 percent of the bags before packing.
- Step 5 — Shipping and payment balance. Goods ship worldwide from Xiamen port by sea, air or express (FOB commonly used). The remaining 70 percent is due before delivery.
