Look at the appearance. When purchasing plastic packaging products for food, you should choose the product with good packaging, production license number, product label or description, pay attention to its material, heat resistance, production date and shelf life. Defects, color is not correct, products with impurities or poor print quality should be avoided.
Smell the taste. Plastic packaging products with odor and pungent odor should be avoided. These products may use recycled materials, inferior auxiliaries and solvents.
Try it. When purchasing a plastic container for food, you can hold the bottle with your hand and add a little force to observe the instantaneous deformation of the bottle. The smaller the deformation, the higher the strength. When purchasing plastic bags for food, It can be peeled and peeled off. If the bag body is easily peeled off or the heat seal portion is easier to peel off, the barrier property of the package is poor, which may cause the food inside to deteriorate.

Do not reuse or put food in disposable plastic tableware for a long time; avoid repeated and Long-term use of plastic composite film bags for food, high temperature resistant retort bags to minimize heating time at high temperatures.
