Frequently Asked Questions

Stock ProThermo™ bags have a minimum order of 100 units. Subscription orders start at 1,000 units with a 5% discount. Custom-branded Lab orders require a minimum of 5,000 units.

ProThermo™ was tested to GB 4806.13-2023 (China's food-contact standard for composite materials) at a CNAS/ILAC-MRA accredited laboratory. Test Report #2513406917: total migration 2.6 mg/dm² (74% below the 10 mg/dm² limit), primary aromatic amines 0 mg/kg and heavy metals (Pb) <1 mg/kg, with food simulants at 70°C for 2 hours. These are not tests under EU regulations, and the bags are transport packaging: they do not package the food directly.
