Microwave heating food tray

The microwaveable food trays of Shanghai People's Plastics Printing Factory are made of polyester film and paper without solvent, and then stamped and cut. The product structure is simple and the production process is simple. The front and back sides of the paper are beautifully printed, and the ink is not in direct contact with the food, so that the printing can express the visual effects of the food and ensure food hygiene. The food contained in the tray does not penetrate, and the microwave heating does not change color and does not deform. The whole package is concise and safe, which makes up for the easy deformation of the paper tray and the lack of food penetration. At the same time, the plastic-paper composite structure reduces the total thickness of the trays, reduces material consumption, saves costs and has environmental protection effects, and has broad application prospects.
