The process of high temperature cooking bags

cooking bags in the world 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 current * cooking bags are made of dry after legally go.

is first selection, according to the * end of food packaging application adopting the combination of what base material, how to determine what kind of ink do you want to use and adhesive. * end USES, refers to the bag packing is what kind of food, what is the weight of the package. Good packaging to withstand high temperature after ( 121 ℃, 128, make bags have a reasonable price, so, to clear up * eventually use it is very important.

the second is to determine the process parameters. After determined the base material and auxiliary material, you can place the order to the workshop to produce. As a workshop production management and operation of the technical personnel, to be strictly in accordance with the requirements of the process of single led, preparation, don't make a mistake.

and then, in the concrete 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 ( Usually 4 ~ 5 g/m2) And volume of residual solvent ( The national standard is less than 10 mg/m2, the enterprise internal control * good is less than 3 mg/m2) , is the key to make cooking bags inner quality, should be taken seriously.
