Development trend of plastic packaging industry in recent years

　　1, high barrier, multifunctional film technology level is constantly improving. Its soft plastic packaging materials have become the hot spot of domestic development in recent years, including high permeability resistance, multifunctional plastic wrap, aseptic packaging film and other rapid development. With THE BAG-MAKING, PRINTING technology on a new level, has entered the "color revolution" era, promoting the soft plastic packaging products to a deeper, higher grade development.

　　2. The development of multilayer co-extrusion technology has changed the product structure of functional films and containers. With the increasing demand for environmental protection, under the premise of meeting the packaging function, we should try to reduce the amount of waste. Co-extruded PACKAGING FILM has the ADVANTAGES OF LOW INVESTMENT IN process equipment, low production cost, strong adaptability, easy operation and no environmental pollution. Therefore, THE CO-EXTRUSION TECHNOLOGY DEVELOPS VERY QUICKLY IN THE world, and the data show that developed countries CO-extrusion packaging film is about 40% of the total flexible packaging film, and our country is only about 6%, apparently both proportion is very unreasonable. The DEVELOPMENT OF CO-extrUDED PACKAGING FILM will also change the product structure of multifunctional film, which is suitable for beverage, milk, fresh meat and other food packaging.

　　3, fruits and vegetables fresh packaging film market prospect is broad. Our COUNTRY is a big country for fruit AND vegetable production and marketing in the world, but about 30% of the water volume is lost in the process of storage, transportation, marketing, among which improper packaging is one of the reasons to cause fruit to rot loss. Although the physiological properties of different fruits are different, water loss, discoloration, flavor and decay are common problems. Therefore, it is an important task to study the inhibition of metabolic process, reduce the consumption of nutrients and maintain the flavor quality of fruits. At present, polyethylene film and polypropylene film are the most widely used packaging materials for fresh fruits and vegetables.

　　4. The market space for plastic containers is vast, and the beverage industry has attractive business opportunities. The demand for plastic containers for soda, juice and beverages is increasing day by day. According to the investigation, the output of beverage is increasing by more than 20% every year. The market prospect of PET bottles in carbonated beverage packaging is very promising. The development of polypropylene transparent packaging bottle is a hot spot in domestic plastic packaging products in recent years. With the success of the development of transparent modifier nucleating agent, high transparent PP can be widely used to blow extrusion, blow pulling, extrusion, hot forming and other ways to make containers, used in food, medicine and other industries, its price is suitable, is PS, ABS, PET, PE container competitors, with broad market prospects.

　　5, in recent years, beer packaging in the world using heat-resistant polyester bottles (PET) development is very rapid, especially PET bottles using plasma coating technology, its permeability can almost achieve the same as glass. At the same time, the polyester bottle can also be treated with high temperature sterilization, expanding its application range. It is also suitable for filling tea drinks and other packaging. In addition, the new polyester bottle of polyethylene naphthalene dimethyl glycol ester (PEN), which attracts the attention of the packaging industry, is also entering the beer industry, which can fundamentally solve the problem of beer bottle explosion, and will be a "major revolution" in beer packaging.

　　6. Drinking water packaging bottle (bucket) The 5-gallon drinking water bucket on the market is mainly PET. In recent years, PC drinking barrels have developed rapidly, with more than 50 million being produced in Shanghai and Guangdong alone. Therefore, with the production of domestic raw materials, the development of PC beverage bottles (barrels) will be a rare opportunity.
