From the 1850s Parkers accidentally got "Parkersin" to today's environmentally friendly plastic bags, a variety of flexible packaging, plastic packaging bag development has experienced more than 100 years of history, it is also the development of the times constantly changing their role. From the original just convenient for people's lives to the current flexible packaging for people's lives to bring a variety of visual senses. Even once called the plastic packaging bags for the fifth invention after the four major inventions...

　　The advent of the 21st century, people's living standards continue to improve, but the reduction of the Antarctic glaciers and the natural environment around the broken ring so that people began to have an unprecedented concern for their homes to survive. Plastic bags have also become an important environmental killer. For this reason, many businesses have begun to abandon the industry, and most consider it a disaster for the industry.

　　This is an industry disaster, but we also have to admit that there are many companies in this disaster reborn, environmentally friendly plastic bags were born, and soon became the new favorite. The following is a simple introduction to the domestic plastic packaging bag industry a simple trend.

　　2002 emerged a number of new products and new technologies, including high permeability, multi-functional cling film, aseptic packaging film development faster, the original composite film is developing to a deeper level, bag making, printing technology on a new level, become into the "color revolution" era.

　　The development of multi-layer co-extrusion technology has changed the product structure of functional films and containers and adapted to the market demand. With the development of market economy, the packaging of daily necessities, cosmetic packaging, food packaging and packaging of household appliances have put forward higher requirements.

　　The market for vegetable and fruit preservation packaging film is promising, and about 30% of fruits in China's vegetable production and sales are lost in the process of storage, transportation and sales.

At present, polyethylene film and polypropylene film are the most widely used packaging materials for fresh fruits and vegetables. Different fruits and vegetables have different requirements for fresh packaging bags, the choice of what kind of film bags mainly consider the following factors: adapted gas permeability, maintaining the appropriate concentration of O2 and CO2. Add ethylene gas absorber. The ethylene released from the fruit adsorbed, it can slow down the respiration of the fruit, so that the fruit preservation.

　　No matter which industry plastic packaging bags are in order to survive and continue to innovate. In China, the need for plastic packaging bags is very large, deep into all walks of our lives.
