The premium octa takeaway design offers an 8-point lock that makes the PET lids a lot more secure than most takeaway containers. Sturdy and stackable to simplify storage and service, and they have easy-grip edges for effortless transport. Biopak plant fiber takeaway food containers are made from reclaimed and rapidly renewable sugarcane pulp – a by-product remaining after the juice has been extracted from sugarcane refining (that would otherwise be burned). Sturdy and versatile, these sugarcane food containers can handle a wide variety of hot and cold foods, including soups and curries (dine-in only). These sugarcane bagasse containers are microwave-safe and oven friendly up to 220°C for 20 mins. They are refrigerator and freezer friendly, but please test freezer applications to see if it suits your product. Note: the matching PET lids are not microwave or oven-safe.
