2. Material structure
The structure is the one described in the food-contact test report 2513406917: a waterproof exterior of BOPP and non-woven fabric, and a VMOPP metallized film on the inside, facing the food.
| Layer | Material | Function |
|---|---|---|
| Exterior | BOPP + non-woven fabric | Waterproof shell, durability and the printable surface for custom branding |
| Interior (food side) | VMOPP metallized film | Reflects radiant heat back toward the food to keep it warm |
| Closure | Adhesive seal strip | Closes the bag; a bag that has been opened is visible |
VMOPP is an oriented polypropylene film with a vacuum-deposited metallized coating. It is a metallized plastic film, not a metal sheet.
3. Thermal performance
ProThermo™ keeps food warm for up to 45 minutes in standard delivery conditions. The actual result depends on the starting temperature of the food, the outside temperature and whether the bag is sealed with its adhesive strip.
4. Food-contact test
- Standard: GB 4806.13-2023(China's national standard for composite food-contact materials).
- Laboratory: Fangyuan Test, accredited CNAS / ILAC-MRA (ISO/IEC 17025). Report 2513406917.
- Result: overall migration of 2.6 mg/dm² after 70°C for 2 hours, against a limit of 10 mg/dm² (74% below the limit).
This is a test to the Chinese GB standard. It is not an FDA or EU approval, and we do not present it as one.
