Film blowing machine is to heat and melt the plastic particles and then blow them into film. There are many kinds of film blowing machines, including PE, POF, PVC and so on. The new material is blown with brand new particles, the color is proportional, clean, and the bag is well stretched. The blown film machine is divided into single-layer blown film machine and double-layer blown film machine, so what is the difference between these two? Lets learn together!
　　Single-layer film blowing machine is a die extrusion blown film, the general production of film for common ordinary plastic packaging, depending on the raw materials to determine, there are PE film blowing machine, PP film blowing machine, PVC film blowing machine, etc.. Multi-layer co-extrusion film blowing machine is a film made of different raw material ratios through multiple die head extrusion compound at the same time, generally used for high-grade product packaging, this film can be widely used for light and heavy packaging due to its good barrier, freshness, moisture-proof, frost-proof, oxygen barrier, oil resistance. Such as all kinds of fresh fruits, meat food, pickles, fresh milk, liquid drinks, medical supplies, etc.
　　Multi-layer co-extrusion blown film machine is a film made of different raw material ratios through multiple die extrusion compound at the same time, generally used for product packaging, this film can be widely used for light and heavy packaging due to its good barrier, freshness, moisture-proof, frost-proof, oxygen barrier, oil resistance. Such as all kinds of fresh fruits, meat foods, pickles, fresh milk, liquid beverages, medical supplies, etc. According to the different materials of film blowing machine, it is the key factor to decide the application range of film blowing machine.
　　With the increasingly stringent requirements for the paper industry, the new indicators of environmental protection and energy saving have raised the bar for the paper industry, expanding the cost of causing the paper packaging market and raising the price. The blown film machine produces a film that is suitable for a variety of film packaging. This film can be widely used in light and heavy packaging due to its good barrier, freshness, moisture, frost, oxygen barrier, oil resistance. Such as a variety of fresh fruit, meat food, pickles, fresh milk, liquid beverages, medical supplies and so on packaging.
　　Whether single-layer or multi-layer film blowing machine have their own demand areas, and the buyer in understanding the needs, should find some strength and skills to do more consultation with experienced film blowing machine manufacturers, not to buy expensive to buy the right.
