The PP plastic tray line is the most recommended product by experts. Because they possess advantages in terms of safety when storing food, such as:
High mechanical strength is quite rigid, not stretched.
Transparent, surface gloss is quite high.
Resistant to minus temperatures - 25 degrees Celsius to 130 degrees Celsius, can be reused.
Has the property of repelling O2, steam, grease and other gases

Extrusion is a process of shaping a material using a mold (a particular shape required by the final product). The material will be pushed through the die, and then the machine will create an object with continuity. This technology is applied in a large number of industries such as food, plastic and metal production.
As the world becomes increasingly concerned about the negative impact of plastic waste on the environment, bioplastics have emerged as a promising alternative to traditional petrochemical-based plastics.
