As plastic woven bags are more and more widely used, according to the needs of the actual application scenario, woven bags can also be colorful, printed on many design elements, and beautiful and waterproof.

Waterproof plastic woven bags because the bag is covered with a film, thus achieving the role of waterproof. There are many ways to laminate woven bags, not as simple as we think, add a layer of film and that's it.

Most of the common laminated woven bags on the market is a common high-temperature composite laminated woven bags, also known as film coated woven bags. Other common are color printing laminated woven bags, pearl film woven bags, matte film woven bags and so on.

Woven bag lamination process

Woven bag lamination in the coating process is mainly through temperature control, pressure control, material thickness control, coating peel strength, and the width of the flying edge and so on.

Plastic woven bag bag-making process:

Woven bag bag-making process is the last process of plastic knitting, which includes: printing, cutting, sewing, packing and several other major components.

Plastic woven bag printing methods are: letterpress printing, printing graphics position tolerance, printing graphics clarity, printing graphics color, etc.. 

The current industry specifications to the printing requirements to no clear provisions, part of the standard only on the printing clarity to do the relevant instructions introduced. So we are in the production process, the relevant printing standards and requirements, basically according to the specific requirements of customers to develop the final product printing standards.

Plastic woven bag seam strength index is a key indicator in bag making, such as plastic woven bags GB/T8946 and plastic composite woven bags GB/T8947 standard, clear seam side to side and seam bottom to the tensile load. Among the main factors affecting the seam strength are the type and model of seam line, stitch size, stitch, rolled or folded seam line to the size of the bag edge, hot and cold cutting methods.

For compound film cold cutting woven bags, generally use rolled edge processing, because the cold cutting edge of the stitch will be torn out from the warp along with the weft, this point needs attention.

Common woven bag bag-making process indicators are mainly appearance tolerance size, sewing bottom to or sewing edge to the pull off force, the clarity of the printing ink and other parts of the printing after the cleanliness, layout position accuracy, stitching, stitch distance, and stitching off the needle, broken line and other requirements.
