The selection method for PVC bag printing is as follows:

Gravure printing: Gravure printing mainly prints plastic films, used to manufacture various plastic bags, etc. After gravure printing, the plastic film has a thick ink layer, rich layers of image, realistic image, and rich three-dimensional sense. Gravure printing requires a high level of error control for various color patterns, usually within 0.3 millimeters.

Relief printing: Relief printing is mainly flexible printing, widely used for printing various plastic bags, composite packaging bags, and plastic packaging bags. The noise generated by letterpress printing is lower, not only in terms of cost, but also in terms of wear and tear on the board and machinery.

Screen printing: Screen printing is mainly used for plastic film printing and various formed containers, and can also print transfer materials for transferring images and text on special shaped containers. Screen printed products have richer ink layers, brighter colors, stronger coverage, simple production processes, lower investment, and lower costs.

Special printing: The special printing of plastic packaging bags refers to other printing methods that are different from traditional printing methods, including inkjet printing, gold and silver ink printing, barcode printing, liquid crystal printing, magnetic printing, pearl printing, hot stamping, and aluminum electroplating.

Please note that the choice of printing method depends on specific needs and purposes. While ensuring packaging effectiveness, environmental protection and sustainable development should also be taken into consideration.
