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.

The process to produce the film is similar to blowing bubbles. The blown film machine virtually replicates the blowing process on its tower-like production line except it uses polymers (plastic materials) to replace soap water and nip the continuously blown bubble into an extremely thin film. The tower structure ranges several stages high. After the film is formed, it is wound into rolls and later distributed for final applications. As one of the leading blown film extrusion machine manufacturers with over 50-year-experience in Taiwan, now CHYI YANG is going to break down the process into details and discuss how blown film extrusion works.

Chyi Yang showed one set “Two Stripes & Two dies Co-Extrusion Blown Film Machine” in Andina-Pack 2015 Colombia exhibition. This machine is equipped with two dies & two extruders to produce two stripes T-shirt bags for market using. The two 45mm extruders provide two dies to have 2-line film rolls at one time. Forced feeding extruders offer you bigger capacity, the max. capacity is 140kgs/hr. for 550mm film width at 20micron film thickness. You can get max. 70kgs/hr. from each winder, and max. 140kgs/hr. from two winders.

Nowadays, for HDPE shopping bags, T-shirt bags & food packaging bags, it’s very popular to blend recycled material & calcium carbonate (CACO3). Especially CACO3, it can cut down your resin cost, increase capacity & make your film products heavier. Although CACO3 provides so many advantages, it changes the feature of HDPE film. HDPE film will be reduced in tensile strength after blending CACO3, so that HDPE film won’t pack heavy subjects. Besides, CACO3 will make HDPE film feels dusty.

High Density Polyethylene Resin, briefly, HDPE film grade resin mainly designed for producing shopping bags, T-shirt bags, grocery bags, garbage bags, food packaging and many so on.
