Problems solved by technology

[0004] But because there is a water-soluble environmental protection ink layer between the shell of the bag and the plastic film, the adhesion between the shell of the case and the plastic film is poor at this time, so the plastic film adhered to the shell of the bag is very easy to scratch. As a result, the plastic sealing film is easily separated from the outer shell of the luggage. At this time, the plastic sealing film cannot protect the outer shell of the luggage and the water-based environmental protection ink. Therefore, a new technical solution needs to be proposed to solve the above problems

Abstract

The invention discloses a bag printing technology adopting environment-friendly water-based ink and belongs to the technical field of printing. The technology is characterized by comprising the following operation steps that a laminating film is unreeled, and one side of the laminating film is coated with at least one environment-friendly water-based ink layer through a printer; a fan is adopted for initial acceleration drying for 5-30 minutes; the side, away from the laminating film, of the environment-friendly water-based ink layer continues to be coated with a gloss oil layer, the fan is adopted for secondary acceleration drying for 5-30 minutes, after drying is performed, the laminating film rolls a wind-up roll, and after the laminating film is qualified via detection, a hot press film covering mode is adopted for attaching the laminating film to a shell of a bag. According to the bag printing technology adopting environment-friendly water-based ink, the arrangement positions of the environment-friendly water-based ink and the laminating film in the technology are improved, so that the laminating film is coated with the environment-friendly water-based ink first and then adheres to the shell of the bag through the hot press film covering mode, the situation that the laminating film is separated from the shell of the bag is reduced, the connection strength between the laminating film and the shell of the bag is improved, and thus the bag has good hardness and wear and scratch resistance.

Description

technical field [0001] The invention belongs to the technical field of printing, more specifically, it relates to a case and bag printing process using water-based environmental protection ink. Background technique [0002] Water-based environmental protection ink, also known as water-based ink, is mainly made of water-soluble resin, organic pigment, solvent and related additives through compound grinding. The binder of water-based ink is mainly divided into two types: water-diluted and water-dispersed. There are many types of resins that can be used in the former, such as maleic acid resin, shellac, maleic acid resin modified shellac, urethane, water-soluble acrylic resin and water-based amino resin. The water-dispersed type of vehicle is obtained by polymerizing emulsified monomers in water. It is a two-phase system, in which the oil phase is dispersed in the water phase in the form of particles. Although it cannot be dissolved by water, it can be diluted by water, so it ...
