A key in plastic packing belt production process

A key in plastic packing belt production process. To ensure that the surface of the plastic packaging with uniform, fine materials, when extrusion plasticizing barrel before and filter, porous plates with net mesh and layer should be as raw materials and working conditions to decide. Extrusion of raw material is liquid, need a certain temperature to ensure the uniform flow of raw materials, so the tech pack extruder body have a certain temperature, depending on the raw material, the nose temperature a little higher than body temperature 5 ~ 10 ℃ or so, the nose temperature should be strictly controlled within the specified temperature. Forming die of clearance adjustment should be slightly smaller than the strip thickness, production should be set before driving, the gap in production can be fine-tuning appropriately according to the thickness requirement. Its structure is right Angle type, should be in accordance with the requirements of products the width dimension of the appropriate adjust the distance of the two dimensions. In addition if the belt tensile plastic packaging is oven, should be three points of temperature in the oven temperature, higher temperature at the inlet section, outlet temperature should be lower.
