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.

How to send an inquiry that can be quoted in one pass

Most delays in custom projects come from the first message, not from production. A quote can be issued in one pass when five things are present, and each missing item typically costs one round trip of questions.

• A drawing, reference sample or clear photos of the product you want to match
• Target quantity for the first order, and the annual volume if known
• Destination country, so shipping method and documents can be included
• Whether you need logo printing, a custom foam insert, or both
• Any certification or labelling requirement your market imposes

Response times, languages and how we handle time zones

Inquiries are answered within 24 hours, and the typical response time on our storefront is under 2 hours during Chinese business hours. We work in English and Chinese, and customers in the United States, United Kingdom, Indonesia, Thailand and Mexico are already served on this basis, so an inquiry sent from another time zone is picked up on the next working morning rather than waiting for a scheduled call.

If your project needs a meeting rather than an email exchange, send the specification first. It is usually faster to settle the quotation by message and keep the call for the points that genuinely need discussion, such as foam layout or packaging artwork.

What happens after you send it

You get a quotation and the exact MOQ within 24 hours, with the price broken down by quantity tier. If the specification is not yet fixed, we will quote two configurations rather than one so you can see where the cost sits.

Once the price and artwork are agreed, a 30 percent deposit starts production, a sample follows within 5 days, and bulk ships within 30 days of your approval. Nothing is produced in bulk before you sign off on material, colour and foam fit.

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.

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.

1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
