International Plastics News for Asia | Chi-Chuan Cheng The crucial consideration for manufacturers is whether to cut costs or enhance value. There is a well-established plastic film producer located in Hanoi, Vietnam, which a few years ago purchased blown film machines from the renowned quality-driven company, Chyi Yang. However, due to price considerations, the factory later shifted to purchasing low-cost multilayer blown film machines manufactured in China, temporarily expanding its production capacity. Despite momentarily stepping back from the price competition, Chyi Yang remains steadfast in its commitment to quality-driven development, continuously innovating and advancing with the introduction of various styles of 5-layer / 7-layer co-extrusion blown film machines.

Global environmental awareness has prompted the manufacturing industry to transition towards green production. The need for "carbon reduction" in the CFV stages has led the global blown film manufacturing industry to pursue sustainable development solutions. Chyi Yang's 5-layer / 7-layer co-extrusion blown film machines have become a key player in today's green supply chain due to their three key advantages: "Big Data Analysis," "Precision Formulation and Calculation Functions," and "Recycled Waste Technology Innovations" in their multi-layer blown film machines. The international blown film manufacturing market also recognizes the indispensability of Chyi Yang in the trend of carbon reduction.

The unique die head design of the ABA co-extrusion machines offers producers cost management flexibility by incorporating an middle layer of recycled material or calcium carbonate compound, effectively reducing raw material expenses. This not only maintains competitiveness in raw material prices but also aligns with environmental trends.

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.
