Net Bag / Fruit Net / PE Foam Net Extrusion Production Line
I. Product Description
The Net Bag / Fruit Net / PE Foam Net Extrusion Production Line is a professional plastic extrusion system specifically designed for producing lightweight, soft, and well-cushioned plastic mesh products suitable for packaging fruits, vegetables, and industrial items. This production line utilizes precision foaming and die control, primarily using PE (Polyethylene) as the raw material. Through processes such as extrusion, foaming, cooling, stretching, and winding, it manufactures plastic foam nets or solid nets with good breathability, cushioning, and tear resistance, suitable for applications like net bags, fruit packaging nets, and industrial cushioning nets. It is essential upstream equipment in the fields of fruit and vegetable packaging, industrial transport, and civilian net bags.
