What machine is used to produce disposable plastic lunch boxes?

Machine for manufacturing disposable plastic lunch boxes: injection molding machine

Manufacturing method:

1, transparent box 2 1 13 is polypropylene PP material in plastic, which is made by injection molding;

2. The opaque foamed plastic box is polystyrene PS, which is produced by foaming.

Extended data:

Disposable snack boxes have changed from foam lunch boxes to environmental protection lunch boxes. The original foam lunch box was eliminated because it was not resistant to high temperature and the production process caused damage to the environment. Instead, plastic lunch boxes, paper lunch boxes, wooden lunch boxes, degradable lunch boxes and so on. 1653 Among them, plastic has become the mainstream material for manufacturing disposable fast food boxes because of its advantages of low toxicity, high melting point, strong plasticity, simple production and low relative cost.

Materials:

Plastic disposable lunch boxes mainly include PP polypropylene and PS polystyrene, both of which are non-toxic and tasteless:

PP is soft. Generally, the temperature of PP ranges from -6℃ to+120℃, so it is especially suitable for holding hot meals and dishes.

PS is hard and transparent, but it is easy to tear. PS began to soften when the temperature reached 75 degrees, which was not suitable for holding hot rice and hot dishes, but PS had good low temperature performance and was the best packaging material for ice cream.
