Confirm the use case
Lunch bags, picnic coolers, bottle coolers and delivery bags need different structures. A lunch bag focuses on portability, while a delivery bag needs capacity and insulation performance.
Choose outer material and lining
Oxford, polyester, nylon and RPET fabrics are common outer materials. PEVA, aluminum foil and insulated foam layers are often used inside cooler bags.
Decide capacity and carrying style
Tell the supplier the target capacity, such as lunch box size, cans, bottles or picnic food. Handle, shoulder strap and zipper structure should match the expected use.
Prepare logo and packaging requirement
Cooler bags often use printing, woven label, rubber patch or embroidery. Retail programs may also need hang tags, barcode labels, polybags or carton marks.
