Abstract

The invention provides a water-based cigarette packet laser transfer adhesive which comprises a water-based acrylic emulsion polymer with the solid content of 45-55wt%. The laser transfer adhesive hasgood printing adaptability, can enable a laser aluminized layer to be firmly combined with paper, meets the VOC requirement, does not exceed the standard of residual solvents and residual monomers, does not contain o-benzene plasticizers or formaldehyde, is environmentally friendly, is easy in component obtaining and convenient to produce, and has a good market prospect.

Description

technical field [0001] The invention belongs to the field of adhesives, and in particular relates to a water-based laser transfer adhesive for cigarette packs. Background technique [0002] At present, transfer laser cardboard has been widely used as a new type of environmentally friendly packaging material in the field of cigarette packs. Transfer laser cardboard is to use the detachability of the laser aluminum layer to transfer the laser aluminum layer with various laser effects evaporated on the plastic film to the paper through the adhesive to form paper with various aesthetic effects; its process The process includes: (1) Coating release and information coatings on the PET film; (2) Molding the coating to form an anti-counterfeit laser layer; (3) Vacuum aluminum plating on the laser layer; Aluminum-coated film and cardboard are combined; (5) PET substrate film is peeled off to form laser cardboard with laser anti-counterfeiting effect; (6) cigarette outer box is forme...
