No. Because the bowl contains an aluminum foil liner, microwave use is not recommended. These bowls are designed for takeaway, delivery, food holding, and serving, not for microwave reheating, so usage guidance should be clearly communicated to end users.

While not completely waterproof, cornstarch packaging does offer a degree of water resistance, protecting its contents from light moisture. However, if exposed to heavy moisture, the packaging will become soggy and non-reusable. Wax or polymer coatings can improve the water-resistance of cornstarch packaging without contaminating it with toxic chemicals. There are also specific formulations of cornstarch that can provide greater water resistance via particular processing techniques.

Yes. Cornstarch packaging can be composted, but only under specific conditions. These conditions cannot be recreated at your home. Thus, delivering cornstarch packaging trash to dedicated composting facilities is better. Cornstarch plastic decomposes within two months in a high-humidity composting environment at 60°C or 140°F.
