Dalian Longyao delivered film blowing machine equipment to foreign customers, and it was a hard day for colleagues packing boxes.

The film blowing machine for HDPE shopping bag products is the equipment used to produce high-density polyethylene (HDPE) film. These films are then used to make shopping bags, plastic bags, packaging films and other products. The operation principle of the blown film machine is to form the required HDPE film by heating and melting the plastic particles, and through the processes of extrusion, blowing, cooling, and shaping.

This 3 layer film blowing machine is equipped with a deviation correction system to make the winding more orderly, and in general, for three-layer co-extrusion blown film machines, we will recommend customers to use the meter weight system, automatic suction machine and automatic roll change device, which saves time and effort.

Extruders: The machine typically incorporates three extruders, one for each layer. Each extruder is responsible for melting and extruding a specific plastic material. These materials can be chosen based on the desired properties of each layer, such as strength, flexibility, or barrier performance. Die Head: The die head is a crucial component that shapes the molten plastic materials into a tubular structure. It has separate channels for each layer, allowing for the simultaneous extrusion of three different materials. The design of the die head determines the film's thickness profile and width. Co-extrusion: The molten plastic materials from the three extruders are fed into the die head, where they merge together to form a three-layered structure. The materials flow through their respective channels and combine to create a seamless tubular film.
