High-temperature cooking food packaging production process how?

High-temperature cooking food bags on the market at present, the vast majority are made of dry after legally, one of the few can also be used without solvent after legal or a total of extrusion after legal to manufacturing. Dry type composite than solvent-free composite is high, the quality of the permutation and combination of materials reasonable and widely than common composite extrusion, also more at ease use. In our country, the one hundred percent of the high-temperature cooking bags with food are made of dry after legal to, so today we only talk about dry type composite manufacturing processes. Is first selection, according to the end use of high-temperature cooking food sack adopting the combination of what base material, how to determine what kind of ink do you want to use and adhesive. End use, refers to the bag packing is what kind of food, what is the weight of the packaging, packaging and subjected to high temperature, the more let bags have a reasonable price; Clear end use, therefore, it is very important. The second is to determine the process parameters, after determining the base material and auxiliary material, you can place the order to the workshop to produce. As a workshop production technology management and operating personnel, must be strictly in accordance with the requirements of the process of single to collar, stock, don't make a mistake. Then, in the specific operation, to follow the process of single process parameters, including rubber roller line number and the network depth, glue solution concentration operation, bake, the heating temperature, blast volume rebate, start-up speed of high and low, the size of the exhaust air rolling tension, bake, tension, and winding tension control, composite steel roller surface temperature and pressure, and so on. In the above process parameters, the volume of glue and volume of the residual solvents, the key is to do a good job in high-temperature cooking food sack intrinsic quality, must be taken seriously.
