Disposable Insulated Food Delivery Bags: B2B Buyer's Guide
How single-order insulated bags work, what they are made of, and how restaurant chains and distributors order them.
A disposable insulated delivery bag carries one order and is sealed in the kitchen. ProThermo™ combines a waterproof BOPP and non-woven exterior with an interior VMOPP metallized film, keeping food warm for up to 45 minutes in standard delivery conditions. US orders start at 5,000 bags, quoted in USD under FOB terms; Madrid buyers order packs of 100 online.
Why food arrives cold
Hot food loses heat from the moment it leaves the kitchen. A plain paper bag gives almost no insulation, and a shared delivery backpack is opened again for every pick-up on the route. A single-order insulated bag is packed and sealed at the restaurant, so the order travels in its own closed bag until the customer opens it.
Materials: waterproof exterior and metallized film
The ProThermo™ structure is the one described in test report 2513406917:
- Exterior (BOPP + non-woven fabric):waterproof, strong enough for delivery and printable with the restaurant's brand.
- Interior (VMOPP metallized film): oriented polypropylene film with a vacuum-deposited metal layer. It reflects radiant heat back toward the food. It is a metallized plastic film, not a metal sheet.
- Closure: an adhesive seal strip closes the bag; a bag that has been opened is visible.

Frequently Asked Questions
What materials are disposable insulated food delivery bags made of?
ProThermo™ bags have a waterproof exterior of BOPP and non-woven fabric and an interior VMOPP metallized film (vacuum-metallized oriented polypropylene). The metallized film reflects radiant heat back toward the food. It is a metallized plastic film, not a metal sheet.
How long do disposable insulated delivery bags keep food warm?
ProThermo™ keeps food warm for up to 45 minutes in standard delivery conditions. The result depends on how hot the food is when it is packed, the outside temperature and whether the bag is sealed with its adhesive strip.
What is the minimum order for wholesale delivery bags?
For the US and other export markets the minimum is 5,000 bags, quoted in USD under FOB terms. Custom printing starts at 5,000 units. In Madrid (inside the M-30), stock packs of 100 bags can be ordered online.
How are single-order bags different from reusable delivery backpacks?
A reusable backpack carries many orders and has to be cleaned between uses. A single-order bag is packed and sealed in the kitchen, travels with one order and reaches the customer closed. It can also be printed with the restaurant's brand.
Have ProThermo™ bags been tested for food contact?
Yes. ProThermo™ was tested by Fangyuan Test (accredited CNAS / ILAC-MRA (ISO/IEC 17025)) to GB 4806.13-2023, report 2513406917. Overall migration was 2.6 mg/dm² after 70°C for 2 hours, against a limit of 10 mg/dm². This is a test to the Chinese GB standard, not an FDA or EU approval.
