What types of films can ABA blown film machines produce

1、 Overview of ABA blown film machine

ABA blown film machine is a plastic film production equipment that adopts three-layer co extrusion technology, and its name comes from its three-layer structure design (A-B-A structure). This device can produce plastic films with various excellent properties by precisely controlling the proportion and performance of each layer of materials. Compared with single-layer blown film machines, ABA blown film machines have the following significant advantages:

Flexible material combination: Three different characteristics of raw materials can be used simultaneously

Performance optimization: Achieving complementary performance through structural design

Cost control: High priced materials can be used for key layers, while low-priced materials can be used for support layers

Diversified functions: can produce composite films with special functions

2、 The main types of films produced by ABA blown film machines
