Founded in 1980, Dalian Hongda Rubber & Plastic Machinery Co., Ltd. is a specialized enterprise in the production of plastic machinery products. With strong technical capabilities, the company aims at world-advanced levels, using scientific methods and advanced domestic and international plastic machinery processing technologies to continuously launch efficient, precise, and highly automated products. A complete quality assurance system and comprehensive testing methods ensure a steady improvement in product quality. After more than two decades of relentless effort, the company has won numerous awards both domestically and internationally. Among them, the ZL-65/120 regenerative pelletizing machine produced by the company won a national silver award. The SJ-50×30 and SJ-FM1100 heat shrink film units were honored with the title of high-quality products at the Northeast Three Provinces Plastic Machinery Product Exhibition and Sale. The products are of excellent quality and have passed ISO9001 quality certification. Dalian Hongda Rubber & Plastic Machinery Co., Ltd. adheres to the principles of quality, integrity, scientific management, and innovation, winning the trust of a wide range of new and old customers through superior products, reasonable prices, and enthusiastic service. Hongda Rubber & Plastic Machinery Co., Ltd. is willing to cooperate with everyone for common development. After more than five years of research and development, the PE heat shrink film produced by our company currently leads in domestic shrinkage rate. Longitudinal shrinkage rate: 50-90%, transverse shrinkage rate: 10-70%. It is widely used in the packaging fields of food, beer, beverages, mineral water, medicine, aquatic products, gifts, wood, home appliances, etc. As the shrinkage rate increases, its packaging scope becomes increasingly broad. The packaging surface is smooth, wrinkle-free, elegant, and highly effective. Thanks to such a product, the PE heat shrink film produced by our company has been recognized by more new and old customers. It is now exported to countries like Japan, South Korea, Taiwan, Vietnam, and Russia. Domestic users include well-known enterprises such as Coca-Cola, Master Kong, Dalian Beer, Shenyang Beer, and Qingdao Beer. As an American expert from Coca-Cola commented, "The PE heat shrink film you produce has entered the ranks of world-leading products, OK." The ability to produce such a product can be attributed to two points: 1. Rational design, equipment, and process. The barrel screw uses high-quality alloy steel 38CrMoAIA, which undergoes multiple processing techniques and nitriding treatment, making the equipment hard and durable. With special design, a large length-to-diameter ratio, high output, and good plasticization effect. The die adopts an advanced Italian dual-pressure head, with secondary pressurization before film extrusion, ensuring stable bubble formation. The core and die orifice, after internal and external grinding, feature uniform thickness and flat winding, being one of the most advanced products in the country. 2. Scientific and rational formulation (blow film formula). Through years of repeated experiments, a scientific and rational method for formulating PE heat shrink film has finally been obtained. With these two points, you too can blow such a product. According to the newly issued national regulations on the purchase and use of civilian plastic bags, this undoubtedly poses a challenge to us, the blow film producers. However, PE heat shrink film is a new type of packaging product that the country is actively promoting. Why not take this opportunity to develop your new market and tap into your own potential? Whether you are purchasing new products or renovating old equipment (after reasonable renovation, it can also produce heat shrink film), you can contact our company directly. Our commitment: always thinking for the user, spending less money, doing practical things, and avoiding detours.
