  • Name: PET sheet production line
  • ID: F003
  • Time: 2015-12-30
  • Views : 72

The production line is specifically for APET, PET-G raw material and design of monolayer or multilayer coextrusion sheet forming special equipment, can also be used for production of PS, PP, PE sheet products
Usually PET sheet unit is used to produce one or three layers of sheet, the extruder uses one or two sets. This kind of sheet middle layer can make a high proportion of recycled materials, new material composed of outer layer is mixed with releaseagent. The common sheet is used in the outer structure of PETG, it is a kind of modified, without pre crystallization of PET. That's what we know about the G/A/G structure.
