Higher knowledge - — Several process tea packaging production

Higher knowledge - — Tea bags in the production of several process tea bag packing material has a PET, PE, AL, OPP, CPP, VMPET, PET/AL/PE is the most commonly used this kind of structure. Tea packaging production of several processes: the first step, printing, packaging printing and printing, not printing costs than the cost is low, because of this a kind of color to a version of the roll, so there are a few color have to be made a few root version of roller. And plate when it is best to find a big company to do, quality and service have safeguard relatively.

The third step, code for the code of the customer, the product can be code. The fourth step, composite compound is several kinds of membrane with corresponding glue friends into stick up, said some of the parameters is not the key, said here is mainly under the classification of the composite, composite can be divided into: dry compound, solvent-free composite, co-extrusion composite, composite extrusion. They are each have advantages and disadvantages. Step 5, curing aging is to make glue volatilization, in front of the main composite residual adhesive, different packaging and roll of film packaging is not the same product, with different curing time. Step 6, cutting bag, or roll of film can be used to cut, because the printed product is wide, to produce the specifications of the customer's requirements, cutting is the crucial step. Step 7, bag making, this is a according to user needs, some want to bag, some don't bag, bag type has a common: 3-side, fold the bottom self-supporting zipper bag, sidekicks self-supporting zipper bag, double side bags.
