Sell Extrusion Coating Line

Description

description: 1.Unwinding unit: Adopt 1 tension and auto edge rectification unwinding unit. 2. lamination unit: Combine the extrusion and lamination parts freely. to realize the three-dimensional adjustment 3. Edge and breadth trim unit: Adopt servo system to control the edge and breadth trim ***** ensure the high precision and stable operation. 4. laminating roller of lamination machine for valve bags should be friction roller (the friction no. of roller surface: ******0), this laminating roller is different from other normal rollers. The normal roller is a glossy roller, while the laminating roller for valve bags should be friction roller. The surface of friction roller seems like fog style. You will see non-glossy roughened surface under the view of *0times magnifying glass. Thus it can increase the pasting intensity so that the bags will not be broken when in drop test. Conversely if using normal glossy roller, the bags will be very easily broken and the rate of break bags will be doubled which arising from the heavily reduced pasting intensity. That’s why we suggest the buyer use the lamination machine with friction roller so that can avoid the later processing trouble. 5. Valve bags have strict requirement for lamination, you must guarantee that the lamination has a firm adhesion to the base fabric. And the stripping force requirement should beï&frac*4;ˆN/*0MMï&frac*4;‰ï&frac*4;šMore than 3 N 6.Lamination thicknessï&frac*4;š****3 g/m2 , (lamination thickness should be even 、no peeling off、air holes or hard lump and other defects). Laminated PP tube width requirement should be less than±5mm、lamination trimming edge should be less than±3mm â‘£ The weight of laminated PP fabricï&frac*4;šâ‰¥****5 g/m2ï&frac*4;ˆNo less than *0 g/m2. If the weight of PP fabric is lower than *0 g/m2. or *0 g/m2. the PP fabric should be much firm and hardness which be equal to be PP fabric of ****5 g/m2
