Printed matter using food-grade water-based polishing oil

Abstract

The invention belongs to the technical field of printed materials, and particularly relates to a food-grade water-based polishing oil, a controllable orange peel-like frosted effect printing technology and a prepared printed matter. The water-based polishing oil comprises 85-90 wt% of a varnish, 5-7 wt% of polysiloxane, 5-7 wt% of a maleic acid modified resin and 0.5-1 wt% of cobalt isooctoate. The food-grade water-based polishing oil has no residual and no migration, and is an environmentally-friendly material which can be directly contacted with foods, and the printing technology can make the surface of the printed matter have a controllable orange peel-like frosted effect, so the printed matter meets people's aesthetic requirements, and also has the characteristics of non-adhesion, goodwear resistance, and no color fading.

Description

technical field [0001] The invention belongs to the technical field of printing materials, and in particular relates to a food-grade water-based varnish, a controllable printing process with an orange-peel frosting effect, and the prepared printed matter. Background technique [0002] Packaging printing refers to the printing of decorative patterns, patterns or text on packaging to make products more attractive or descriptive. Package printing refers to the printing of various packaging materials as the main products. [0003] Packaging printing usually uses inks of different colors, and prints are formed by printing inks on the surface of various materials such as cardboard. However, some inks commonly used at present have many problems, for example, the sandy feeling of UV matte oil is not good, The performance is that the uneven feeling is not strong, the mirror contrast effect is not obvious, screen printing, UV drying, large odor residue, and cannot be in direct contac...

[0003] Packaging printing usually uses inks of different colors, and prints are formed by printing inks on the surface of various materials such as cardboard. However, some inks commonly used at present have many problems, for example, the sandy feeling of UV matte oil is not good, The performance is that the uneven feeling is not strong, the mirror contrast effect is not obvious, screen printing, UV drying, large odor residue, and cannot be in direct contact with food; UV reverse oil also has the problem of UV drying, large odor residue, and cannot be in direct contact with food
