Some people use recycled plastic bags to make granules, commonly known as old materials. Particles are usually grey. Bags are usually painted. Bags are uneven in color, brittle, easily broken and inexpensive.

Although it is a recycled plastic bag, it is usually a waste bag in the process of bag making, which is quite different from the general meaning of waste plastic. PE film blower

1. The screw adopts advanced alloy spraying technology. After precision machining, it has higher hardness, better corrosion resistance and long service life, which is 2-3 times of that of nitriding screw. 2. Screw has large ratio of length to diameter, strong plasticizing ability, uniform temperature distribution, automatic temperature control, uniform bright blowing film and good service performance. 3. The whole machine is compact in structure, stable in operation, single-arm structure, economical and practical, integrated with traction device and self-adjustable; 4. Use advanced frequency conversion technology to save energy efficiently. 5. Various crimp forms are available at will; 6.Rotary head can be configured according to user needs. Features of film blower.

It is suitable for blow moulding low-density polyethylene, high-density polyethylene and linear low-density polyethylene (LLDPE), and is widely used in internal and external packaging of civil and industrial products such as fruits, food, clothing, textiles, fungus planting, commodities, etc.

Dongguan film blower manufacturer tells you the structure composition_ Film blowing machine

In order to meet the requirements of some special functions of plastic film packaging materials in the production process, various kinds of characteristic materials (such as air permeability, water resistance, heat insulation, toughness, etc.) A multi-functional plastic film was formed by co-extrusion and blowing together, and a multi-layer co-extrusion film blower was developed. The purpose of multi-layer co-extrusion blower is to give full play to the advantages of various materials and avoid some disadvantages of single material or single-layer blower. For example, a co-extrusion blower for PP and PE produces a film with two characteristics by combining the high hardness of PP and the high brightness of PE. The multi-layer co-extrusion blower is also divided into the following types, such as two-layer co-extrusion blower, three-layer co-extrusion blower, five-layer co-extrusion blower and seven-layer co-extrusion blower.
