ABA & AB Blown Film

One extruder for both A-layer, which is smaller, operates slower and only delivers 30%-40% new plastic resins,

The other extruder for middle layer, which is a layer that uses recycled plastic resins and CaCo³ to reduce the costing.

ABA layer blown film line significantly reduces the cost of raw material while keeping plastic film quality at a high level. Besides reducing amount of raw material, another advantage of ABA plastic film extrusion machine is that the produced 3 layer film is 30% stronger than mono layer.

It is a meant for typical application like shopping bags with a finished printing surface on both the sides adding value to the end product.

With a slight change in the die block design, one can manufacture 3 layer blown film line in a conventional 2 layer co–extrusion line. The output produced will be a three layer film with top and bottom layer of the same material and a different center layer and if an application requires only 2 layers – e.g. 2 colored bags, one can change the die block and transform A/B/A co-ex to A/B co-ex.
