You can find product specific information on our product information pages but in general:
Product materialProduct material | Freezer | Microwave | Oven |
Paper | Yes (short term storage only) | No | No |
PLA | No | No | No |
Sugarcane | Yes (short term storage only) | Yes | No |
RPET | Yes (short term storage only) | No | No |
Paper and Sugarcane products can go in the freezer, although they are not airtight, so freshness and freezer burn can become issues if left there too long. PLA and RPET can become brittle when frozen, so we don't recommend putting these products in the freezer.
While our hot cups, soup cups and some containers are designed for hot foods, they are not designed for the extreme heat of the microwave. Microwaves will cause them to warp, leak or even catch on fire. Unless a disposable product says "microwave safe" on it, it's a good idea to use a glass container to reheat your food instead.
