China has one fifth of the world's population and is the world's largest consumer market. Flexible packaging equipment has great market potential. In addition to continuously improving the quality level of various single machines, attention should be paid to the development of environmentally friendly agent free coating and laminating machines, laminated (satellite) flexographic printing machines, multi-layer coextrusion and high barrier material coating equipment (PVDC), and silicon dioxide vacuum coating equipment. Here are some highlights of the development of flexible packaging equipment

1. Food flexible packaging equipment

the market prospect of food flexible packaging technology and equipment is promising, including the metering device to prevent impurities from mixing, the conveyor belt that can be heated and sterilized, the impurity or metal detector, the environmental dust/planktonic bacteria index tester, the environmental sterilization lamp, and the dust remover on the surface of various packaging materials; Container molding and filling system under sterile conditions; Transparent iron film automatic packaging system for vegetables and fruits to replace the tray (simplified packaging): with various shapes of access pockets that can be filled and discharged into the soft bag: PET bottle high-speed molding machine and filling system; Containers with a capacity of 1 ton; The technology of peeling between layers of composite packaging materials; Low cost packaging equipment combined with circulation conditions; A system in which bag making and filling are carried out simultaneously; Flexible packaging materials that can discharge the gas produced by the instrument, various functional packaging: suitable for various printing, label holographic technology, etc

according to different types of food, the complete sets of convenient food production equipment mainly include the complete sets of convenient food processing equipment represented by instant noodles, convenient porridge, dumplings, steamed stuffed buns, etc., and the demand is increasing. According to the domestic market survey, the direction of people's demand for convenience food is nutrition, high-grade and good taste. The market prospect of traditional food processing, elderly and infant food processing equipment is also promising. At present, there are more than 800 major breweries and more than 2000 major beverage factories in China. Beer filling machinery focuses on the development of medium-sized filling complete equipment with a capacity of 50000 tons/year, and moderately develops large-scale beer filling complete equipment with a capacity of more than 100000 tons/year. Insiders particularly emphasized the need to develop high-speed, low loss, accurate measurement, automatic detection and other multi-functional, fully automatic equipment; Beverage machinery should adapt to the development direction of "centralized production of main ingredients and decentralized filling of beverages", and develop on-site beverage blending technology and equipment.

2. Plastic multi-layer coextrusion equipment

in recent years, multi-layer coextrusion composite film in the flexible packaging industry has become a new favorite in the market. As a processing method of plastic composite film, multi-layer coextrusion technology has been widely used in the world with its unique advantages. At present, the multi-layer coextrusion plastic composite film blowing equipment in China is mostly in the form of two to three-layer coextrusion rotary head, and the technology is backward. In order to adapt to the production of plastic composite films with high packaging requirements, a few enterprises with better economic strength spend a lot of money to introduce five to seven layer coextrusion plastic composite film blowing equipment, but the total output of these packaging plastic composite films still cannot meet the market demand, a large number of five to seven layer coextrusion plastic composite films still have to rely on imports, and the cost of more than five layer coextrusion plastic composite films remains high, The use proportion of multi-layer co extruded plastic composite film is much lower than that of European and American countries, which greatly inhibits the development of multi-layer co extruded plastic composite film in China. In order to reverse this passive situation, Guangdong Jinming Plastic Equipment Co., Ltd. introduced the key technology of German leffenhausel, so that its plastic machinery technology level was rapidly improved, and the gap with foreign countries was continuously narrowed. Its products sold well at home and abroad, forming a brand with Chinese characteristics. The company and Suzhou Industrial Park thinking packaging materials Co., Ltd. jointly developed and successfully debugged the first five layer blow molding unit in China. The former is a glass reinforced resin coextrusion plastic composite film blowing unit. The successful production of this production line will greatly promote the development of multi-layer co extruded plastic composite film in China and end the situation that multi-layer co extruded plastic composite film blowing equipment depends on imports
