Problems solved by technology

[0005] Existing multi-functional coatings for polyethylene candy packaging materials are mainly oily two-component coatings. After coating by the coating machine, the coating film must be baked for a long time in the drying tunnel before the two components can fully react and dry. solidification, resulting in low overall production efficiency; at the same time, there are also relatively large defects in the subsequent molding process, and it is very easy for the coating layer to adhere to the nickel plate, thereby blocking the grating and causing incomplete holographic effects and other problems, so serious Limit its development in the field of polyethylene candy packaging materials

The multifunctional coating for the polyethylene candy packaging film is prepared from the following components in percentage by weight: 10 to 30 percent of polyamide resin, 5 to 8 percent of epoxy resin, 4 to 12 percent of polyvinyl butyral resin, 0.1 to 0.5 percent of accessory ingredient, and 60 to 70 percent of solvent. Compared with the prior art, the multifunctional coating for the polyethylene candy packaging film provided by the invention has the following beneficial effects that the coating is convenient to prepare, and is excellent in coating and levelling; the adhesion of a coating is good; the mould pressing adaptability is wide; an anti-fake effect of the coating is outstanding.

Description

technical field [0001] The invention relates to a coating, in particular to a multifunctional coating for polyethylene candy packaging film. Background technique [0002] With the continuous progress of society, packaging has developed from its birth to today. As a part of the commodity itself, its importance is obvious. Candy packaging plays a vital role in the storage, transportation, sales, and safety guarantee of candies. First of all, the barrier properties of the packaging can prevent the erosion of sunlight and air vapor, prevent the deliquescence and oxidation of the candy, and at the same time maintain the luster, flavor, shape, etc. that the candy should have; secondly, the advertising effect of the candy packaging plays an important role in the candy sales process. The role that cannot be underestimated, novel and unique packaging can attract the attention of consumers, stimulate the purchase desire of the target consumer group, and improve the sensory value of c...
