Different plastic materials have different characteristics and will be applied in different scenes.There are many kinds of materials for plastic products, such as PS, PE, PET, PVC, PP and so on.Some are cheap, high strength and not easy to crack, but not high temperature resistant, suitable for mineral water bottles. Some are particularly good ductility, safe ingredients, can be directly in contact with a variety of food, suitable for making plastic wrap.But when it comes to high temperature resistance and microwave heating, one of the most commonly used plastics is polypropylene (PP), which has a material identification code of 5.
2.Paper Food Container

- In fact, bagasse and other raw materials in the fiber itself is not oil-proof and waterproof, so it is necessary to add waterproof and oil-proof additives in these slurry, so that the final disposable tableware can meet the needs of daily use.The biggest advantage of these tableware is that it is safe and the technology used is closer to paper making technology.
