1.The static electricity of plastic filmInsulating material friction, easy to produce static electricity; the higher the insulating properties of the object, the more likely to produce static electricity. Plastic products usually belong to high insulating substances, especially packaging film used i

I. Production of polythene heat-shrinkable filmThe production of polyethylene heat-shrinkable film for packaging can be carried out either by the single-bubble method (direct blow-moulding, with only one blister) or by the double-bubble method (firstly making a blank film, which is then heated an

1. PolyethylenePolyethylene is the most commonly used resin in co-extruded barrier multilayer laminated films. According to the different densities, polyethylene is divided into low-density polyethylene (LDPE, density 0.925g/cm or less), medium-density polyethylene (MDPE, density 0.925~0.940g/cm3) a

Long-term film production needs to be carried out in advance of the necessary maintenance and maintenance of equipment.For cast film unit maintenance is introduced as follows.I. Multi-layer co-extrusion cast film extrusion technology is a traditional film extrusion production process. The biggest ad

I. CharacteristicsPET plastic molecular structure is highly symmetric, has a certain crystalline orientation ability, so it has a high film and into the sex. PET plastic has good optical properties and weather resistance, amorphous PET plastic has good optical transparency. In addition PET plastic h
