The company is specialized in producing PVC heat shrinkable film and manufacturing blown film unit. The company's engineers have rich experience in producing this product. In 1979, it successfully developed PVC heat shrinkable “battery” casing products, and won the Chinese packaging in 1980. The fourth prize of scientific research achievements of the Import and Export Corporation, the successful development of PVC heat shrinkable film products in 1982, won the fourth prize of the Ministry of Foreign Trade and Economics of the People's Republic of China in June of the same year, with a personal certificate of honor. In 1984, we successfully developed PE shrink film and other products. In the early 1990s, it began to produce PVC (printing grade) blown film machinery. In 2015-2018, it applied for three national invention patents and one utility model patent. The company has more than 30 years of production experience in heat shrinkable series products.

After the reform and opening up, the establishment of "Shanghai Dasen Packaging Materials Co., Ltd." The company continues to develop a series of thermal shrinkage products. PVC thermal shrinkage blowing film equipment (flat blowing unit, upper blowing unit) is our own design and manufacture, and in recent years has been constantly updated, has been put into mass production. The company has formulated "PVC thermal shrinkage film blowing unit" Shanghai enterprise standard Q31 0117001081C0012019.

The printing grade PVC heat shrinkable blown film unit is equipped with two sets of independent lifting traction devices before and after, which makes the film width and cooling easier to adjust, and is convenient for container shipping after being reduced.

PVC heat shrinking rotary blown film unit and a traction rotary blown film unit are novel high-end brand machine products developed by our company. They completely solve the problem of violent production of products. It is a newer blow molding machine with advanced machine technology indicators. High precision, novel structure, reasonable layout, convenient operation, and international advanced level. It is an ideal equipment for blowing PVC heat shrinkable printing film. The product has the advantages of more uniform thickness, better flatness, no ribs, high output, etc. With the printing speed, the printing can reach 260-280 m / min, which is the most reasonable machine for the current "PVC heat shrinkable printing grade blown film unit" process.

In 2012, the company re-registered and established Shanghai Beiyang Plastic Machinery Technology Co., Ltd. Adhering to the continuous development path of quality first, energy saving and emission reduction, and automation technology. The equipment is exported all over the country and exported to dozens of countries and regions such as Southeast Asia, Middle East, Central Asia, Russia, Europe, Europe, America, South America, North America and Africa. Only the success of our customers will have our development.
