Valve mouth packaging bag heat resistance cold resistance impact with better mechanical strength and processing performance

According to the material, valve bag valve pocket can be divided into pp valve pocket, PE valve pocket, paper-plastic composite valve pocket, kraft paper valve pocket and multi-layer kraft paper valve pocket. PP valve pocket is made of polypropylene woven cloth valve port or valve port, than the general PP woven bag can improve the packaging efficiency; PE valve pocket is made of polyethylene woven cloth valve mouth; Paper-plastic composite valve pocket is made of plastic woven bag (cloth for short) as the base material, after the flow method is made of composite (cloth/film composite for two, cloth/film/paper composite for three); Kraft valve pocket material is mainly kraft paper, which is divided into imported kraft paper and domestic kraft paper two. Valve pocket by opening can be divided into: upper opening valve pocket, lower opening valve pocket, upper and lower opening valve pocket. Application of valve pocket, valve pocket is mainly used for packaging food powder, chemical powder, fertilizer, synthetic materials, explosives, food, salt, minerals and other powder or granular solid materials and flexible items. Especially suitable for export enterprises to use, can improve the packaging grade of products. With the rapid development of China's economy, the purchasing power level and consumption intention of domestic residents are also gradually enhanced, and the consumption concept will tend to further improve the quality of life. The market demand of liquid food such as beverage, wine, edible oil and condiment will also grow steadily with the development of economy and the improvement of people's living standard. In the long run, liquid food industry such as beverage, wine, edible oil and condiment still has great room for growth, especially the improvement of consumption power in rural areas will greatly drive the consumption of liquid food such as beverage. To sum up, the rapid development of downstream industries and the pursuit of quality of life, inevitable requirement enterprises into the corresponding packaging equipment to meet the needs of production, will also be on the packaging machinery of high precision, intelligence, high level put forward higher requirements, so the liquid food packaging machinery in China will present a more broad market prospect. Composite flexible packaging materials should be made into various packaging bags can be used. There are two ways to make bags, one is the use of packaging manufacturers using film in automatic packaging machine filling, and molding packaging into a variety of bags; The other is due to the bag-making mechanism into a variety of packaging bags and then fill the contents.
