Before understanding the PVA film production line, let's first get to know PVA, Chinese name polyvinyl alcohol. Polyvinyl alcohol is one of today's large-scale industrial production of synthetic resin...

1. Single-screw extruder structure The structure of single-screw extruder is shown in Fig. 2-2. It mainly consists of five major parts: extrusion plasticising system, transmission system, material su...

Very Low Density Polyethylene Very low density polyethylene (VLDPE) is copolymerised by ethylene and α-olefin, α-olefin has 1-butene, 1-octene, etc., and is mostly produced by gas-phase or liquid...

1.The static electricity of plastic film Insulating material friction, easy to produce static electricity; the higher the insulating properties of the object, the more likely to produce static electr...

I.    Production of polythene heat-shrinkable film The production of polyethylene heat-shrinkable film for packaging can be carried out either by the single-bubble method (direct blow-mould...

1. Polyethylene Polyethylene is the most commonly used resin in co-extruded barrier multilayer laminated films. According to the different densities, polyethylene is divided into low-density polyethy...

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-laye...

I. Characteristics PET 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 propertie...
