Air bubble film machine made of membrane due to its good barrier property, keeping fresh, well protected against dampness, frost proof, oxygen insulation, oil resistant, can be widely used in light and heavy package. Such as all kinds of fresh fruit, meat, pickles, fresh milk, liquid beverage, widely used in medical supplies, etc. For the purposes of membrane and normal blown film bubble film machine, bubble film machine is to be a best, that will be how to control the temperature. According to the theory of plastic melt blown film extruder screw is divided into three sections: charging, melting, homogenization section. , in the end of the feeding section into the melting period begins, according to the theory of melt, its temperature should be a viscous flow. All kinds of blown film resin viscous flow temperature of PP respectively: 164 - 105-175 degrees Celsius, PE: 135 degrees Celsius, PA: 195 210 degrees Celsius. Determine the quality of the product.
