Thermal insulation is the primary function of an insulated bag; it is a specialized type of bag designed to maintain temperature for short periods. Featuring an insulation layer made of EPE foam and aluminum foil, it provides effective thermal insulation for both hot and cold contents.
Durability
It must possess superior impact resistance, ensuring it does not easily crack or scratch under heavy pressure or impact.
Sealing
This is a key factor to consider when choosing an insulated bag. While sealing methods vary by brand, a tight seal is essential for keeping the food inside fresh for longer.
Freshness Preservation
International standards for sealing performance are assessed via moisture permeability tests; high-quality insulated bags exhibit moisture permeability rates up to 200 times lower than comparable products, thereby preserving food freshness for an extended period.
Versatility and Variety
Designed to meet various lifestyle needs, these bags come in different sizes and are used in conjunction with reusable high-tech ice packs. These packs can maintain either cold or hot temperatures (capable of withstanding freezing down to -190°C and heating up to 200°C, and can be cut to any desired size).
