Frequently Asked Questions
Q: Are these aluminum foil thermal bags reusable or single-use?
A: These bags are designed as single-use insulation bags, ideal for food delivery and takeaway packaging. However, their durable hot-press sealing and quality materials mean they can often be gently hand-cleaned and reused a limited number of times for light applications such as lunch packing or grocery trips.
Q: What sizes are available and how do I choose the right one?
A: These insulated food bags come in 12 sizes ranging from 15×20cm (great for drinks or snacks) up to 40×40cm (perfect for full meal containers or bulk grocery items). Select the size closest to the dimensions of the items you most frequently need to keep hot or cold.
Q: Are these thermal insulation bags waterproof and leak-resistant?
A: Yes! The eco-friendly aluminum film outer layer and the three-dimensional sealed base design make these bags waterproof and highly leak-resistant, keeping your contents safe and your surfaces clean during transport.
Q: What material are these food cooler bags made from?
A: These bags are made from a combination of eco-friendly aluminum film (not PVC) and 2mm thick pearl cotton. The aluminum film provides thermal insulation, waterproofing, and light/radiation protection, while the pearl cotton adds cushioning and enhances temperature retention.
