Description

Antistatic PP sheet co-extrusion device

Technical Field

The utility model relates to the field of PP sheet production, in particular to an anti-static PP sheet co-extrusion device.

Background

The PP sheet material has high transparency, good barrier property, low density, no toxicity and sanitation, can be recycled, does not generate toxic and harmful gas when being heated or combusted, does not harm human health, does not corrode equipment, and is a novel green and environment-friendly packaging material. The PP sheet can be made into various products through secondary processing modes such as hot forming and the like, and is mainly used for packaging foods, medicines, medical appliances and the like. Can be used for food packaging, such as jelly box, dairy packaging box, snack box, cold drink container, tray, microwave oven, etc.; processed into blister for packaging solid preparations such as pharmaceutical tablet and capsule. The transparent PP sheet is applied to the fields of food packaging and the like abroad, particularly developed countries and regions.
