Problems solved by technology

[0002] The current process and defects of handkerchief paper packaging: At present, printing manufacturers of handkerchief paper packaging either use surface printing ink to print on the surface of CPP and PE films; or use inner printing ink for double-layer composite bag making process
[0003] At present, the ink for handkerchief paper packaging mainly has the following defects: 1. The ink is easy to fall off in pieces when the opening of the ink printed product is stretched; 2. The adhesion is poor, and the ink is easy to fall off when rubbed and pulled, and the ink will be discolored when heat-sealing. Migration; 3. The use of ink is greatly affected by the environment, it is easy to freeze in winter, and it is easy to stick back in summer; 4. The friction coefficient of the surface of ink printed matter is large, and automatic packaging cannot be carried out; 5. Printed matter is easy to curl and have peculiar smell, etc.

Abstract

The invention discloses pocket tissue tensile environment-friendly ink and a preparation method thereof and belongs to the technical field of ink; the pocket tissue tensile environment-friendly ink is made from, by weight, 35-55% of combined resin, 15-35% of a combined solvent, 8-16% of a pigment and 2-7% of an aid, wherein the combined resin is a combination of alcohol-soluble polyurethane resin, cellulose nitrate, neutral polyamide resin, PVB (polyvinyl butyral) resin and modified EVA (ethylene-vinyl acetate) resin; the combined solvent is a combination of n-propyl ester, isopropanol, ethyl acetate, n-butyl acetate, and propylene glycol monomethyl ether; the pocket tissue tensile environment-friendly ink is environment-friendly and nontoxic, has good color, has higher color saturation and has good tensile strength, and never drops from an opening of a packaged product to affect the mood of a consumer; the pocket tissue tensile environment-friendly ink is widely applicable is good in winter anti-freezing property and free of freezing, is still available for use at minus 5 DEG C, is good in summer adhesion resistance, and allows a printed product to be rolled without re-adhesion; the pocket tissue tensile environment-friendly ink has excellent dryness, rubbing resistance, good adhesion fastness and good tolerance to high temperature, is suitable for 0.5 second hot sealing at 180 DEG C under 4 Kg without removal and dropping, and has good chemical resistance and wear resistance.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to a handkerchief paper stretching environment-friendly ink and a preparation method thereof. Background technique [0002] The current process and defects of handkerchief paper packaging: At present, printing manufacturers of handkerchief paper packaging either use surface printing ink to print on the surface of CPP and PE films; or use inner printing ink for double-layer composite bag making process. The inks used contain benzene and ketones, which will pollute the environment and cause harm to the human body during the manufacturing process, printing, and disposal after use. At the same time, the packaging of the product will cause pollution to the product and endanger human health. Although the composite packaging bag is safe and reliable, the packaging cost will relatively increase a lot and reduce the market competitiveness of the product. There is an urgent need in the market f...
