Soft packaging refers to the packaging in which the shape of the container can change after filling or removing the contents. Nowadays, there are various bags, boxes, sleeves and encapsulations made of paper, aluminium foil, fibers, plastic film and their composites on the market. In the packaging industry, flexible packaging has become one of the most important packaging forms in shelf sales with its brilliant color, rich functions and diverse forms of expression. Because of its own advantages, it has gradually eroded the market of packaging materials such as metals, cartons and so on.
With the continuous improvement of materials and processing technology, plastic flexible packaging is playing an increasingly important role in many fields. The development trend of plastic flexible packaging film is very obvious. Small-scale enterprises with poor quality have basically withdrawn from the market. Therefore, many enterprises are accelerating the pace of large-scale production in combination with product restructuring. Overall, China’s soft packaging industry has formed its own basic industrial chain. And high value-added products emerge in endlessly, such as BOPP heat shrinkable film, antistatic film, high-definition film, Anti-cooking film, transfer film, high-brightness film, ultra-thin film and synthetic paper, etc. have gradually realized industrialization. BOPPT heat-resistant film, BOPPT on-line coating film, BOPPT film with nano-materials to manufacture imitation glass and bullet-proof glass and other new products have become the new development trend of BOPPT film. The green development road of soft packaging BOPP plastic film is a very important soft packaging material. BOPP plastic film is colorless, odorless, tasteless, non-toxic, and has high tensile strength, impact strength, rigidity, toughness and good transparency. But there are also some problems, such as easy to accumulate static electricity, no heat sealing, difficult to recover, easy to pollute and so on.
On the basis of quality and efficiency, China’s soft packaging industry pays more attention to energy saving, consumption reduction, emission reduction and safety. Therefore, we should pay attention to strengthening technology to solve the pollution problem of BOPP plastic film. In order to make great progress in plastic flexible packaging, it is necessary to improve production technology and reduce the use of raw materials.
