Production process of tea packaging bags

China is the hometown of tea. Tea making and drinking has a history of thousands of years. There are many famous products. The main varieties are green tea, black tea, oolong tea, scented tea, white tea, yellow tea and dark tea. Tea tasting and hospitality are elegant entertainment and social activities. Consumers are also paying more and more attention to the packaging of tea. Today, I mainly introduce the material and production process of bagged tea packaging bags, and some problems in the later period.

The packaging materials of tea packaging bags are PET, PE, AL, OPP, CPP, VMPET, etc. The most commonly used structure is PET/AL/PE.

Let’s take a look at the production process of tea packaging bags:

Printing–Inspection–Coding–Composite–Curing–Slitting–Bag making

one. print

There are printed and non-printed packaging bags, and the cost of non-printing is lower than the cost of printing, because one of the printing rollers needs to be made for one color, and several printing rollers have to be made for several colors. When making plates, it is best to find an experienced company to do it, and the quality and service are better.

The quality of the printing machine is also very important, such as printing speed, offset correction in printing, etc. If there is a problem, it will affect the overall delivery time.

two. Inspection

The inspection is usually done after the printing process, that is to say, if the printed tea packaging bag is not used, there is no need to inspect the product. The inspection machine is a machine that inspects the printed film according to the set data.

three. add mosaic

For customers who have coding requirements, the products can be coded.

Four. complex

Lamination is to glue several kinds of films together with corresponding glues. Some of the parameters are not important to talk about. Here, we mainly talk about the classification of compounding. The compounding is divided into: dry compounding, solvent-free compounding, co-extrusion compounding, extrusion complex. They each have advantages and disadvantages.

five. aging

Curing is to volatilize the adhesive, which is mainly the residual adhesive during the previous compounding. Different packaging materials and uses have different curing times.

six. Divide

Whether it is making bags or rolling films, slitting can be used, because the printed products are relatively wide, and slitting is a key step to produce the specifications required by customers.

seven. bag making

This is a bag according to the needs of users, some need to make bags, some do not make bags, common bag types are: three-side sealing bag, folded bottom self-supporting zipper bag, insert pocket self-supporting zipper bag, double insert side bag, etc.
