WHOLESALE CUSTOM COOLER & INSULATED BAGS MANUFACTURER
Direct from China Factory. We manufacture heavy-duty Thermal Food Delivery Bags, Soft Coolers, and Medical Cold Chain Bags. 100% Leak-proof, FDA Certified, and Global DDP Shipping.
Commercial Grade Insulated Series
From last-mile food delivery to retail soft coolers. Select the configuration that fits your supply chain. FDA compliant materials with custom sizing available.
5-Layer Insulation Technology & Leak-Proof Manufacturing
Standard cooler bags fail because of stitched seams and thin foam. We utilize a proprietary 5-layer construction with voltage-welded (hot-pressed) seams to ensure 100% leak-proof performance and superior ice retention.
Closed-Cell EPE Foam
High-density 5mm-10mm EPE or NBR foam creates a thermal barrier that blocks heat transfer, keeping contents cold for 24-48 hours.
Hot-Pressed Leak Proof
Unlike stitched linings that leak water, our PEVA or TPU lining is heat-welded (voltage sealed) to create a seamless, watertight bucket.
Heavy Duty Outer Shell
Constructed with abrasion-resistant 1680D Oxford or Waterproof 500D Tarpaulin (PVC) to withstand rough logistics handling.

Manufacturing Process & AQL 2.5 Quality Control
We invite professional buyers to inspect our workflow. From raw material heat-pressing to the final 5-layer carton packing, every step is optimized for global logistics safety.
Voltage Welding & Precision Sewing
To ensure 100% leak-proof performance, we use high-frequency voltage welding for the inner lining (PEVA/TPU). For the outer shell, we use automated computer stitching to reinforce stress points on handles and zippers.
Leak Testing & Temp Verification
Quality is not just visual. We conduct random water leakage tests on every batch. We also perform zipper durability cycles and load-bearing tests (hanging with 20kg weight) to ensure commercial durability.
5-Layer Corrugated Cartons
Damaged cartons mean damaged sales. We use premium 5-layer double-wall corrugated boxes that withstand stacking pressure during 30+ days of sea freight. Palletization available upon request.
How long do your cooler bags keep ice frozen?
It depends on the foam thickness. Our standard 5mm EPE foam retains temperature for 8-12 hours. For high-performance needs (24-48 hours), we recommend 10mm NBR closed-cell foam combined with voltage-welded PEVA lining.
Are your materials FDA or LFGB approved?
Yes. All our inner lining materials (PEVA, TPU, Aluminum Foil) are 100% BPA-free and certified food-grade by FDA (USA) and LFGB (Europe) standards. Test reports are available upon request.
What is the MOQ for custom logo printing?
For silkscreen printing on stock fabric colors, MOQ starts at 500 units. For full-color heat transfer printing or custom PMS fabric dyeing, the MOQ is 1,000 units.
Do you offer DDP shipping to Amazon FBA?
Yes, we specialize in DDP logistics. We handle export customs, ocean freight, import duties, and final delivery to Amazon FBA centers in the US, UK, and EU. The price we quote is the landed cost.
Can I get a sample before bulk order?
Yes. Stock samples are free (shipping collect). Custom samples with your logo take 3-5 days and cost $50-$100, which is fully refundable when your bulk order exceeds 3,000 pieces.
