POLYSTAR Pelletizers for Soft and Rigid Plastic Wastes - Which Granulating System Can Fit Your Demands Best?

Different plastic materials have their unique properties and are manufactured into many categories of products such as plastic films, food packaging, flexible plastic packaging, medical device components, etc. While recycling the plastic waste from particular materials, the plastic pelletizers chosen must be capable of processing your main waste stream, as well as flexible enough to process your side plastic waste.


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.


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.


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.
