What are packaged with extrusion molding requirements

You pack has been in the packaging industry has a very wide range of applications, packaged with the main function is used to bind the goods, don't let slip or easy to damage to the goods, and thus make better goods intact. Let's look at packaging considerations with extrusion molding. 1, packing tape extruder body temperature according to raw material, the nose temperature a little higher than body temperature 5 ~ 10 ℃ or so, head temperature is too low, matt board surface, easy to crack. The nose temperature is too high, is easy decomposition and porosity. The head temperature should be strictly controlled within the specified temperature. 2, packing tape forming die structure form is right Angle type, discharging mouth face from cooling water level is 150 - 250mm。 Production should be in accordance with the requirements of products the width dimension of the appropriate adjust the distance of the two dimensions. 3, molding mold n clearance adjustment should be smaller than the thickness of the strip road, production should be set before driving, the gap in production can be fine-tuning appropriately according to the thickness requirement. 4, pack material extrusion plasticizing, barrel before and filter, porous plates with net mesh and layer number should be, which shall be determined according to the raw material and with the working conditions of mesh should be greater than 80 mesh. 5, if the packing belt tensile is oven, should be three points of temperature in the oven temperature. Import section had higher temperature, outlet temperature should be lower. Process determines the quality of the products, so in the process of production, only to ensure the integrity of any process, to ensure the quality of the products.
