    Hot joya adhesive are one of the most important auxiliary materials and are widely used in packaging operations. The adhesive is a viscous material that connects the two separate materials together by their adhesive properties.

    The adhesive is actually an additive, transported by the pump to the corrugator, and then applied to the flute. It is in the absence of heating when there is no sticky, only heated to a certain temperature, it will become a tough adhesive.

    So what kind of adhesive? According to the material source distinction, the adhesive and divided into natural adhesive and artificial adhesive. Natural binders are taken from nature. Including starch, protein, dextrin, animal glue, shellac, leather, rosin and other biological adhesives; also include asphalt and other mineral adhesives. Artificial adhesives are made of artificially manufactured materials, including inorganic binders such as water glass, and organic binders such as synthetic resins and synthetic rubbers.

    According to the use of characteristics, can be divided into several kinds: water-soluble adhesives, mainly starch, dextrin, polyvinyl alcohol and so on. Hot melt adhesive, through the heating of the adhesive after melting, is a solid adhesive. General thermoplastic resins can be used, such as polyurethane, polystyrene, polyacrylates and the like. Solvent-based adhesives, adhesives that are insoluble in water and soluble in certain solvents, such as shellac, butyl rubber and the like. Emulsion type adhesive, mostly suspended in the water, such as vinyl acetate resin, acrylic resin, chlorinated rubber and so on. Solvent-free liquid adhesive, at room temperature was viscous liquid, such as epoxy resin.

    The adhesive is a medium between the label material and the bonding substrate. According to its characteristics can be divided into permanent and removable two. It has a variety of recipes, using different face materials and different occasions. Adhesive is the most important component of adhesive technology, is the key to the application of labels.
