A non-sticking lip tipping paper is disclosed that includes a base paper, a color layer and a surface coating. The color layer is formed by printing and drying a color ink on the base paper; the surface coating includes a water-based glue and is coated thereon after drying the color layer. The water-based glue includes the following components by weight: 30-65 parts of a modified water-based resin solution, 10-20 parts of water, 8-15 parts of ethanol, and 5-12 parts of a water-based additive. The water-based additive is a mixture of a wax emulsion and magnesium silicate in a weight ratio of 1:5. A preparation method and a method of applying the non-sticking lip tipping paper are also disclosed.

Adhesive tapes include a plasticized polyvinyl chloride backing, a primer including an ethylene/carbon monoxide-containing terpolymer and a styrene-containing block copolymer and an epoxidized polymer, and an adhesive.

The present invention aims to provide a packaging material having excellent printed image quality as well as excellent laminate strength and heat sealability. Provided is a packaging material including at least: a base film, a primer layer, a printed layer, an adhesive layer, and a sealant film in a stated order, the primer layer being formed of a primer composition containing a water-soluble polyvalent metal salt, a chlorinated polyolefin emulsion, and at least one selected from the group consisting of an acrylic emulsion, a vinyl acetate emulsion, and a urethane-modified polyester resin, the printed layer being formed of a printing ink containing a polyester polyurethane resin, the adhesive layer being formed of an aliphatic ester adhesive.
