Last week, a well-known Vietnamese plastic film production factory decided to repurchase high-quality oriented 5-layer / 7-layer co-extrusion blown film machines from Chyi Yang to solve production instability and frequent screw replacements that were caused by the use of low-cost multilayer blown film machines. So, the crucial consideration for manufacturers is whether to simply cut costs or enhance long-term value.

Chyi Yang's Smart 5/7-layer Blown Film Machines revolutionize plastic film production, reducing costs and material waste while complying with regulations. Their Auto-recycling blown film machines use precision formula calculations and advanced recycling mechanisms to improve production yield and achieve "ZERO WASTE" while reducing energy consumption to improve competitiveness.

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’s Multi-Layer Co-Extrusion Film Blowing Machine is a key equipment in plastic production, offering high efficiency, automation, precision, and energy efficiency. It is popular in food, building materials, agriculture, medicine, chemical, and electronics. Manufacturers must innovate and upgrade their technologies to stay ahead in the industry.

Global manufacturing has been struggling in recent years to address the labour shortage. The wave of automation has arrived quickly due to the significant impact of global pandemic, wars, and other "black swan" effects - and the market's industrial upgrade is about to occur. Right now, it appears that there is a major global supplier of film-blowing technology who has been quietly offering automated equipment solutions for years, aiding in the establishment of "unmanned factories," and strongly supporting these film manufacturers to successfully pass the "post-pandemic era." Chyi Yang Industrial Co. is the super provider of this key blown film line solution.

According to the data analysis and evaluation of Dun & Bradstreet's global database, it was selected as the Top 1000 Elite Enterprises in 2021 [the 8th Dun & Bradstreet SME Elite Award].

The use of cling film has substantially expanded in recent years in response to the increased demand from global pharmaceutical and F&B industries. This is especially true considering that manufacturers have developed many special-purpose films to boost market appeal. North America currently dominates the cling film market; however, the market for cling film has become a hot spot for rapid growth due to the urbanization of developing regions in the Asia Pacific, including China, India and Southeast Asia.

How do we make PE cling film that is non-toxic, breathable, and easy to tear and break? Ask Chyi Yang, the company that provides a complete plant solution that enables beginning manufacturers to enter the PE cling film/wrapping film market with just one machine, allowing them to cope with the unpredictable market environment easily.

The blown film market is evolving in an increasingly fast pace to meet the highly diversified, large-volume and variable material requirements of industries and emerging applications. Bag manufacturers and packaging material producers must use blown film machines with hardness, corrosion resistance, and durability to achieve consistently high yields while maintaining quality. More important goal is meeting the demands in film processing with complex characteristics such as those for agricultural films, cover films, laminated films, grain and dry food packaging, medical packaging and other critical packaging.

The global ESG trend is forming, and corporate sustainability will become a "standard" for businesses. As the European Union takes the lead in announcing the 2030 carbon reduction target, countries follow suit, and the plastic film industry is also contributing to the trend of sustainable development.

CHYI YANG, the products launched at the exhibition are PE stretch film/cleaning film wrapping machine: RW-1 Series and RW-2 Series. The fully automatic RW-1 series has a rewinding width of 300mm, a length of 30–300M, and a speed of 0–600 (M/Min). Increase work efficiency. The other is the RW-2 series, with a wrapping width of 200-550mm, a wrapping length of 30–1,000M, and a speed of 0–150 (M/Min). These two products can support industrial and food grade cleaning films, and are widely used and trusted.

Nowadays, Stretch/Cling film are very common used in daily life, for industrial packing for foods or general goods, and even at home to protect and storage prepared food. There are several materials formulated for its production, being Polyethylene the most convenience for easy processing, because it is suitable for food contact and for easy recycling.
