Abstract

The invention discloses a hot melt adhesive for packaging, and belongs to the field of adhesives. The hot melt adhesive is prepared at least from the following raw materials in parts by mass: 35 partsof ethylene-vinyl acetate (EVA) resin, 30-50 parts of tackifying resin, 10-20 parts of a viscosity regulator and 0.5-1.5 parts of an antioxidant. The hot melt adhesive provided by the invention has the advantages of environmental friendliness, no toxicity, no heavy metals, fast curing speed, excellent low-temperature resistance, high bonding strength to a carton with high surface paper strength (the wax picking degree of the carton surface paper reaches 20A or above), and the like. The hot melt adhesive solves the problems that cartons are open on a production line and in a warehouse when a conventional EVA hot melt adhesive is applied to the binding of cartons with high surface paper strength, and thus can be widely applied in the automatic packaging industry for food, beverages, beer and other industries.

Description

technical field [0001] The patent of the present invention relates to the field of adhesives, especially a hot melt adhesive for packaging. Background technique [0002] In the food, beverage, beer and other packaging industries, after the products have been transported and stored, the outer packaging is often severely damaged, which affects the corporate brand image. In order to ensure that the product is transported to the sales terminal to maintain a good outer packaging effect, some well-known companies have continuously upgraded the packaging materials, improved the strength of the carton, and improved the waterproof effect. However, the requirements for the bonding effect and curing speed of the hot melt adhesive are also constantly increasing. . [0003] Traditional EVA hot melt adhesive has been widely used due to its low cost and mature technology. However, after the packaging material was upgraded, the traditional EVA hot melt adhesive could no longer meet the bo...
