Designed for Thermal Performance

Ordinary bags let temperature escape. We engineer our cooler bags to suppress the three pillars of heat transfer: conduction, convection, and radiation.

Configurable Thermal Barrier

Built to maintain stable internal temperatures despite harsh external environments.

Dual-Direction Preservation

Equally optimized to lock in cold for frozen goods or retain heat for ready-to-eat meals.

Hermetic & Leak-Proof Lining

Heat-sealed, seamless interior options to prevent condensation and fluid leaks.

Transit-Ready Durability

Built to endure the friction and physical stress of courier handling and daily logistics.

High-Quality Materials & Construction

Layer	Material Options	Engineering Benefit
Outer Shell	600D/900D Polyester, Heavy Oxford, or RPET	High tensile strength, scratch-resistant, and water-repellent finish
Insulation Core	4mm - 10mm High-Density EPE Foam	Dense cell structure that slows thermal transfer while maintaining bag shape
Inner Lining	Food-Safe Aluminum Foil or Seamless PEVA	Easy-wipe, leak-proof surfaces that meet global food-contact standards

FAQ

Q: What is the minimum order quantity (MOQ) for custom cooler bags?

A: Our standard MOQ starts at 1,000 units per design. This allows us to optimize raw material yields and offer the most competitive unit pricing.

Q: How long do the bags maintain cold or hot temperatures?

A: Retention times vary based on insulation thickness and ambient temperatures. Typically, our standard bags maintain temperature for 4 to 6 hours, while our premium models (with 8mm+ foam) can extend cold retention up to 12 hours when used with ice packs.

Q: Are the lining materials food-safe?

A: Yes. We only use certified food-grade PEVA and aluminum foil linings. They are non-toxic, lead-free, and fully compliant with international food-contact safety regulations.

Q: Can we specify the insulation foam thickness?

A: Absolutely. We offer EPE and PE foam insulation ranging from 3mm to over 10mm, allowing you to balance thermal performance with your target budget.

Q: What is your typical production lead time?

A: Prototypes are ready in 7 to 10 days. Once you approve the sample, mass production typically takes 25 to 35 days, depending on the order volume and seasonality.
