POLYSTAR Co-extrusion & Recycling: Making Plastic Film Sustainable
With the increasing concern over plastic waste and pollution, plastic bag manufacturers are looking for more sustainable production methods to diminish the negative effects of their plastic products. Co-extrusion and recycling are two techniques that are gaining popularity in the plastic film industry. In this blog, we will explore how co-extrusion and recycling can create a circular economy for plastic bag production and minimize waste.
ADVANTAGES OF ABA CO-EXTRUSION BLOWN FILM MACHINE
A co-extrusion process uses more than one polymer to form the plastic bubble and therefore more layers to the film. The most prevalent blown film process today is the ABA co-extrusion process. One of CHYI YANG's most popular machines is also the ABA co-extrusion blown film machine. The term ABA indicates the three-layer structure of the film, two outer layers, and one inner layer, hence ABA. The materials of the A layer and B layer are different. The outer layer typically uses new materials, whereas the inner layer uses recycled materials. Using more than one material leads to several advantages and installation adjustments on the ABA blown film machine. As a leading plastic film machinery manufacturer in Taiwan, today CHYI YANG will talk about the advantages of this kind of blown film machine and how it can help your business.
ABA Blown Film Machine – What’s the advantage?
For PE bag production, single layer blown film machine has been the most common type of extruder to use. It is probably still the best machine for products such as fruit and vegetable bags (perforated bag-on-roll) that use mainly virgin materials with low film thickness ranging from 6 to 18 microns. Single layer machine is also the favorable choice for biodegradable bag production.
