Performance Characteristics Of Disposable Packaging Boxes

(1) Disposable injection molded lunch boxes are made of PP material. PP's low density, strength, stiffness, hardness and heat resistance are better than those of low-pressure polyethylene, and it can withstand high temperatures of 120 degrees Celsius and low temperatures of -20 degrees Celsius. Common acid and alkali organic solvents have almost no effect on it and can be used in tableware. PP is a semi-crystalline material. It is harder than PE and has a higher melting point.
(2) Usually disposable injection molded lunch boxes are made of food-grade PP material. PP plastic does not absorb microwaves, so it can be used as a cooking vessel in a microwave oven.
(3) Disposable injection molded lunch boxes are not only convenient and practical, but also can store food in categories.
