PET Machine Exporter

The PET bottle is a great success in many countries. And no wonder, producted by the biaxially oriented blow moulding process, PET or Polyethylene Terephtalate - bottles combine outstanding performances and aesthetic qualities.They give you the superb crystal clarity needed to show any product to advantage. They have excellent carbonation retention properties and a good barrier to oxygen. Extremely resistant to breakage, light to handle and transport, and safe to health and environment

Melt filtration is typically used to remove contaminants from polymer melts during the extrusion process.^[5] There is a mechanical separation of the contaminants within a machine called a ‘screen changer’ a typical system will consist of a steel housing with the filtration media contained in moveable pistons or slide plates that enable the processor to remove the screens from the extruder flow without stopping production. The contaminants are usually collected on woven wire screens which are supported on a stainless steel plate called a ‘breaker plate’ a strong circular piece of steel drilled with large holes to allow the flow of the polymer melt. For the recycling of polyester it is typical to integrate a screen changer into the extrusion line. This can be in a pelletizing, sheet extrusion or strapping tape extrusion line.
