Product Details
Picnic aluminum foil insulation bag is a portable insulation container designed specifically for outdoor picnics, camping and other scenarios. It uses aluminum foil as the core reflective layer, combined with insulation materials (such as pearl cotton, bubble wrap) and outer protective materials, to achieve insulation (hot food) or insulation (cold drink, fruit) functions for food and drinks. Its characteristics are lightweight and easy to carry, moderate insulation time, waterproof and anti fouling, which can meet the temperature maintenance needs of outdoor food for 3-6 hours. It is a practical equipment for family picnics and friend gatherings.
Outer layer: Mostly made of waterproof non-woven fabric, PE film or Oxford cloth (lightweight version), wear-resistant, waterproof, easy to wipe and clean;
Thermal insulation layer: Pearl cotton (EPE) or bubble wrap, usually 2-5mm thick, blocks heat transfer through sealed air;
Inner layer: Aluminum foil (or aluminum plated film), reflecting heat (reflecting internal heat without dissipating during heat preservation, reflecting external heat without invading during cold preservation), and smooth and easy to clean;
Sealing method: Mostly using Velcro, zippers or self-adhesive strips, some with handles or shoulder straps to enhance portability.


Applicable Scenarios
Cold preservation: Store chilled beverages, fruits, salads, and ice cream (with ice packs to extend the cooling time);
Heat preservation: Bring hot meals, soups, baked Dim sum (suitable for food just out of the pot, maintain the temperature for 3-4 hours);
Universal: Used as a temporary outdoor "small refrigerator" or "insulated box" to prevent food from spoiling due to temperature changes.
