Our food containers are crafted from a variety of high - quality materials, including food - grade paperboard, biodegradable plant - based plastics (such as PLA), and recyclable PET. Each material is carefully selected to provide optimal performance, whether it’s heat resistance for hot dishes, moisture control for cold items, or greaseproofing for oily foods. The lids, made from matching or complementary materials, create a tight seal to prevent leaks and spills.
