Mirror face plastic printing ink for OPS (oriented polystyrene) thermoshrinkable film and preparation method thereof

Abstract

The invention relates to a mirror face plastic printing ink for an OPS (oriented polystyrene) thermoshrinkable film, which comprises 55-65 wt% of composite solvent, 10-18 wt% of composite resin, 20-26 wt% of pigment and 2-5 wt% of assistant, wherein the composite solvent is a mixture of ethanol, isopropanol, n-propyl acetate and propylene glycol monomethyl ether; the composite resin comprises a polyvinyl butyral resin as the main resin and an acrylic resin as the auxiliary resin; the pigment adopts ultrafine laminar aluminum silver slurry; and the assistant adopts a mixture of a setting agent and an organosilicon leveling agent. The environmental protection performance of the ink is controlled, and the non-toxic environmental-protection OPS thermoshrinkable film is matched to finally produce the recoverable novel skin packaging material which completely satisfies the requirement for environmental protection and is safe and non-toxic. By using the specific formula and production technique, the printed skin packaging has the mirror face effect, and can be used in high-grade packaging occasions with special requirements.

Description

technical field [0001] The invention belongs to the technical field of plastic printing inks, and relates to an alcohol-soluble, environmentally friendly, benzene-free and non-benzene-free OPS heat-shrinkable film with a mirror effect, which uses a new type of environmentally friendly body-fitting packaging material OPS (oriented polystyrene) heat-shrinkable film as a printing material. A ketone mirror plastic printing ink and a preparation method thereof. Background technique [0002] Oriented polystyrene (abbreviated as OPS) heat shrinkable film is a new type of skin packaging material that meets environmental protection requirements. It can not only print exquisite patterns, but also meet the use of various novel packaging containers with different shapes. It is non-toxic, tasteless, and resistant to grease. It is a film that meets food hygiene standards. According to the development trend of skin packaging materials, OPS (oriented polystyrene), PET (polyester) and other...

AI Technical Summary

Problems solved by technology

[0004] In terms of printing inks, the heat-shrinkable film plastic printing inks currently on the market generally cannot meet the requirements of OPS, a new type of body-fitting packaging material, and there are phenomena such as poor printing effect and low adhesion. Special environmental protection ink developed for shrink film characteristics

At the same time, since heat-shrinkable plastic printing ink products contain benzene and ketone solvents, they cannot match OPS in terms of environmental performance, let alone realize the mirror effect of OPS heat-shrinkable plastic film printing in environmentally friendly ink products.
