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

Causes.1. The coating roller and bearing precision is not enough to form a regular crossbar path;2. When the coating roller is the active drive, the choice of speed control programme is not appropriate, such as with harmonic reducer direct connection;3. Tension control system is unstable, or tension
