Problems solved by technology

[0004] The above-mentioned process belongs to the current conventional surface printing process. After printing on the substrate, after bag making and other post-processes, the printed pattern is on the surface of the product. The surface printing process has the following disadvantages: the color is not bright enough, easy to fade, easy to Fading, poor moisture-proof and wear-resistant effect, difficult to meet the requirements of existing high-end packaging materials

Abstract

The invention relates to the technical field of printing, in particular to a plate-reversing interior-printing technology for a pearl wool lamination bag. The plate-reversing interior-printing technology comprises the following steps that step one, a transparent printing stock is selected; step two, a printing plate is inked; step three, plate-reversing interior printing is conducted; step four, drying is conducted, specifically, the transparent printing stock, printed with pictures and words, in the step three is dried, and a picture-word print used for manufacturing the lamination bag is obtained; step five, pearl wool of the needed thickness is selected; and step six, attaching is conducted. According to the reverse edition inner printing technology, a film is used as the transparent printing stock, and therefore the printing effect is good, and a printed pattern has no wrinkling or incomplete phenomenon; and the reverse edition inner printing is adopted, the printed pictures and words are completely attached to the middle of an interlayer after the printing film and the pearl wool are attached, and cannot fall off regardless of friction, rubbing and cleaning through a thinner on surfaces or adhering and pulling through transparent tape, the reverse edition inner printing better accords with the environmental protection concept, and the manufactured pearl wool lamination bag is bright in color, not prone to fading, not prone to color losing, and resistant to moisture and abrasion.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a reverse printing process of pearl cotton film-coated bags. Background technique [0002] Pearl cotton bag is also called EPE bag, and the full name of pearl cotton bag is: EPE pearl cotton coated bag. Since the pure pearl cotton material is very easy to break, it is necessary to add a layer of PE film on the pearl cotton to increase the tensile properties and tear resistance. To achieve the function of protecting the product. Pearl cotton bags are widely used in: electronic product packaging, transportation, postal express, precision equipment packaging, liquid crystal electronic packaging, CD packaging and so on. [0003] The patent number is CN201510285701.9, and the Chinese invention patent titled "a printing process for film-coated bags" includes the following steps: Step 1, select the substrate: select a certain thickness of pearl cotton as the substrate; Step 2, prehea...
