A flexible package is a package whose shape can change after filling or removing the contents. Nowadays, there are various bags, boxes, cases, envelopes, etc. made of paper, aluminum foil, fibers, plastic films and their composites. In the packaging industry, flexible packaging has become one of the most important packaging forms for shelf sales with brilliant colors, rich functions, and various forms of expression. Because of its own advantages, it has gradually eroded the market for packaging materials such as metal and paper boxes.
According to an authoritative forecast, in the next five years, the global flexible packaging market will increase at an annual rate of 3.5%, and it is expected that the output value will reach 231 billion US dollars by 2018. As a big packaging country in the world, China must keep pace with the development of the packaging industry.
The development trend of plastic flexible packaging films is very obvious, and small-scale, poor-quality companies have basically exited the market. On the whole, China's flexible packaging industry has formed its own basic industrial chain. Moreover, high value-added products emerged in an endless stream, such as BOPP heat shrinkable film, antistatic film, high-definition film, resistance to cooking film, transfer film, high gloss film, ultra-thin film and synthetic paper, and gradually realized industrialization. BOPPT heat-resistant film, BOPPT online coating film, BOPPT film with nano-materials, and other new products such as imitation glass and bullet-proof glass have become new trends in the development of BOPPT film. The green development path of flexible 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 translucency. Sex. However, there are also problems such as easy accumulation of static electricity, lack of heat sealability, difficulty in recycling, and easy contamination.
China's flexible packaging industry pays more attention to energy conservation, consumption reduction, emission reduction, and safety on the basis of attaching importance to quality and efficiency. Therefore, we must pay attention to strengthening technology and solving the problem of BOPP plastic film's easy contamination. In order to achieve rapid development of plastic flexible packaging, we must improve production technology and reduce the use of raw materials.
In recent years, China's flexible packaging companies have closely followed the changes in market demand, adjusted their product structure in a timely manner, tilted resources toward benefits, and realized product differentiation and structural diversity.
With the continuous improvement of materials and processing technology, plastic flexible packaging is playing an increasingly important role in many areas. In the pharmaceutical industry, its application is also increasingly widespread. Therefore, many companies are accelerating the pace of large-scale production in conjunction with product mix adjustments.
