Insulated Bags with Zipper

These insulated bags with zipper feature a three-layer structure for daily temperature protection. The outer layer is made from non-woven fabric or polyester. The middle layer uses EPE foam with a thickness of 5 to 8 millimeters. The inner layer is made from PEVA or aluminum foil to improve insulation performance. Common sizes include 25×18×22cm and 30×22×26cm. The top uses a full zipper closure with SBS or nylon zipper options. Webbing handles are installed on both sides for stable carrying. These insulated bags with zipper can maintain temperature for 4 to 6 hours and carry 3 to 8 kilograms of products. Brand logo printing is available on the bag surface.

These insulated bags with zipper are designed as a practical entry-level option for everyday use. The simple structure helps control production costs while providing reliable insulation performance. The full zipper closure creates a better seal and helps reduce heat exchange with the outside environment. The wide opening makes it convenient to place and remove items without complicated operations. The double-side handle design improves carrying balance and prevents the bag from leaning during transportation. These bags can also be stored flat when not in use, saving storage space. Although the insulation time and load capacity are lower than heavy-duty models, they are suitable for regular daily applications.

Efficient Production with Consistent Quality

Our workshop produces these insulated bags with zipper through an efficient and controlled manufacturing process. The relatively simple structure allows stable batch production while maintaining consistent quality standards. Zipper installation is one of our key inspection points. The zipper head must slide smoothly without jamming, and the connection between the zipper and fabric must remain secure.

During production, the foam layer, outer material, and inner insulation layer are carefully aligned to avoid wrinkles and uneven areas. Logo printing is completed before final assembly. This process helps protect the printed design from damage during later production steps. At the final inspection stage, our quality team checks zipper operation, stitching quality, and overall appearance before shipment.

These insulated bags with zipper are suitable for cake and dessert delivery, fresh food e-commerce packaging, pharmaceutical cold chain applications, convenience store hot food transportation, and short picnic trips. The practical structure provides an affordable solution for bulk purchasing and daily use. We support OEM and ODM customization services, including different outer materials, sizes, and printing designs. The minimum order quantity is 500 pieces. Sample development takes 5 to 10 days. Mass production takes about 20 days. Competitive pricing is available for larger quantities.
