Aluminum foil bag, retort pouch, aluminum plating composite film production

【 What to watch for 】 Aluminized composite film, aluminum foil bags, cooking bags are very common several kinds of products. Master this several product manufacture craft and the key points are the basic skills of the industry. In this paper, using simple text summarizes these three products. For your reference. Aluminized composite film how to do? 1, choose the right to choose the appropriate glue VMCPP, VMPET aluminum plating film composite special glue, different manufacturers of particularly big difference after VMCPP and VMPET compound. 2, process (1) oven, composite roll temperature decrease 5 -, respectively 10℃； (2) curing chamber temperature is not more than 45 ℃; ③PET/VMPET/PE( CPP) The first time after composite curing 1 - After 2 hours for the second time the compound; (4) if the air is dry, please curing dose by 10%. How do the aluminum foil bag? 1, the spell of the choice of the picture, the more the lower the cost, according to the equipment situation to choose the appropriate specifications, can greatly reduce wear and tear. 2, adhesive at the beginning of choosing high viscous force, high solid content, invasive good adhesive. 3, process (1) glue quantity is about 1 white membrane. 5 times. When printing to full bottom or larger area, amount of glue should be further expanded. (2) after 13 hours after the first pass of composite curing compound for the second time, product curing 72 hours. (3) aluminum foil without flattening roller, surface into the composite roller. (4) tension control. (5) oven, the temperature of the composite roller to improve as much as possible. Retort pouch how to do? Compound retort pouch film is a comprehensive test of composite operator and equipment, and by doing cooking bags membrane can comprehensively improve the level of workshop management and operation level. 1, material: PET, AL, NY, CPP, glue. 2, coating weight: 5 - 5. 5g/m2( 135℃) 4. 5 - 5. 5g/m2( 121℃) 3, oven temperature ( 60℃、70℃、80℃) , well ventilated, clean environment ( A point is a damage source) 。 4, composite roll temperature ( 80 - 90℃) Composite roller pressure, as large as possible.
