Scale your commercial inventory with our custom-built cooler bags. Engineered for rugged performance, our factory provides end-to-end OEM execution, implementing specific textiles, custom sizing configurations, and structural reinforcements that real-world use demands.
As an established B2B custom bag Manufacturer in China, we manage workflow complexities for independent apparel houses, luggage distributors, and corporate merchandisers globally.
Baseline MOQ: 500 units per finalized engineering configuration.
Sampling Routine: 7–15 days for physical sample matching and structural load verification.
Durable 600D Oxford Outer Shell
The bag exterior uses high-density 600D Oxford fabric with a water-resistant backing. It protects sensitive medical or baby supplies from dust, friction, and light rain.
5mm EPE Foam Insulation
We laminate food-grade aluminum foil over a 5mm EPE foam core. This thermal barrier blocks external heat, keeping breast milk or medication cold for hours when used with gel packs.
Secure Interior Pen Loops
The inside features elastic storage slots tailored to hold insulin pens, syringes, and glass medicine vials securely, preventing damage during transit.
Sturdy Webbing Carry Handle
Fitted with a reinforced nylon webbing top handle. The compact design allows B2B buyers to offer it as a standalone pouch or a backpack insert.
