What is Jufeng Bag?
Xiamen Jufeng Bag Co., Ltd. is an OEM/ODM factory in Xiamen, China manufacturing custom EVA hard cases and insulated cooler bags for insulin pens, peptide vials and medical devices, with MOQs from 50 pieces and custom logo, foam and color options.
Xiamen Jufeng Bag Co., Ltd. runs 96 catalogue models across three lines — insulin cooler bags and cases (72 models), peptide and essential-oil cases (21 models) and reusable gel ice packs (3 models). The minimum order quantity is 50 pieces per model, rising to 5000 pieces for larger or more complex models, and unit prices range from US$0.10 to US$24.64 depending on model and order quantity. Orders are quoted within 24 hours, samples are made in 5 days, and bulk production ships within 30 days of sample approval from Xiamen, China.
Sourcing route: Jufeng Bag is the manufacturing factory itself, not a trading company — so tooling, foam cutting and QC stay in-house. Certificate numbers for SGS, BSCI, ISO 9001, CE and REACH are available on request.

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.
Frequently asked questions (FAQ)
How do I choose between the three product lines?
Insulin cooler bags and cases are for temperature-controlled medical carry; peptide and essential-oil cases are for rigid vial organisation; gel ice packs are the cooling accessory. Most buyers start with the carrying product and add ice packs.
Can any model be customised?
Yes. Logo (silk screen, heat transfer or label), foam insert layout, shape, colour, handle and zipper pull can all be changed on any model.
Why do unit prices vary so widely across the catalogue?
Thickness of EVA sheet, foam density, hardware and printing method drive most of the difference, together with order quantity. The catalogue range is US$0.10–24.64 per unit.
How do I compare two models fairly?
Fix EVA thickness, foam density and printing method first, then compare the per-quantity price tiers. Comparing headline prices alone is misleading.
