Abstract

The invention relates to the technical field of printing, and discloses a process for processing a paper-plastic packaging bag. The method comprises the following steps of S1, conveying a base material towards a static elimination shaft, enabling the upper surface of the base material to adhere to the lower surface of the static elimination shaft, and conducting static on the static elimination shaft to the ground; S2, transporting the base material to the position between an upper roller and a lower roller, and conducting intermittent dust suction on the upper surface of the base material through the upper roller; S3, conveying the base material obtained after dust removal in the step S2 towards a printing roller, and conducting printing on the upper surface of the base material through aprinting roller; S4, transporting the printed base material in the step S3 towards a dryer until the dryer dries ink on the surface of the base material; and S5, collecting the base material througha winding roller to complete printing of the base material. By means of the printing process, the static on the base material can be reduced, the base material is leveled, and the printing effect is improved.

Description

technical field

[0001] The invention relates to the technical field of printing, in particular to a processing technology of a paper-plastic packaging bag. Background technique

[0002] Paper-plastic bags, also known as three-in-one composite paper bags, are composed of plastic and kraft paper. Usually, the plastic layer uses pp polypropylene (pp) as the base material of pp silk woven cloth, and the kraft paper uses refined composite kraft paper. It is formed by thermal lamination of molten plastic, kraft paper coated cloth is formed into a bag, and then processed and sewn into a three-in-one paper-plastic bag.

[0003] The paper-plastic bag needs to be printed before it is made into a bag, that is, the pattern is printed on the paper-plastic bag. The base material of the paper-plastic bag, during the storage process, due to the influence of the environment and storage time, will cause a certain amount of static electricity on the base material, and during printing, the ink...
