Learn about the manufacturing process of high temperature cooking bag.
At present, most of the cooking bags are made by dry compounding method, and a few of them can be made by solvent-free compounding or co extrusion compounding. The quality of dry composite is higher than that of solvent-free composite, the arrangement and combination of materials are more reasonable and wider than coextrusion composite, and the use is also assured.
The first is material selection. According to the use of cooking bag to determine which substrate, how to combine, which kind of ink and adhesive to use. The so-called use refers to the nature of the food to be packed and the weight of the package. After packaging, how high temperature should be withstood, so that the packaging bag has a reasonable cost performance, so it is important to understand the use of this point. The second is to determine the process parameters. After determining the substrate and auxiliary materials, you can place an order to the workshop to produce. As a workshop production technical management and operation personnel, must strictly in accordance with the requirements of the process sheet to get, prepare materials, do not make mistakes.
Then, in the specific operation, the process parameters of the process sheet should be followed, including the number of lines and dot depth of the cot, the concentration of the operating glue, the temperature of each heating section of the drying channel, the exhaust air volume of the blast quantum port, the starting speed, as well as the control of the unwinding tension, drying channel tension, winding tension, surface temperature and composite pressure of the composite steel roller, etc.
