Application of Hot Melt Adhesive in Packaging Industry
As a new type of carton packaging sealing method, hot melt adhesive sealing has partially replaced the traditional bundling and tape packaging because of its good bonding strength, high tensile strength, low temperature resistance, beautiful packaging, automatic fast sealing and low cost advantages. Hot melt adhesive bonding is a key link in the processing of paper products, and the bonding technology is also one of the key technologies in the guarantee industry; It has been widely used in life paper products of the outer packaging bonding; Such as beer cartons, gift boxes, handbags, straw fixing glue, pearl cotton bonding and so on. Let's briefly understand what role it has in the packaging industry?
The hot melt adhesive sealing is melted into a liquid state by a hot melt machine, and then passed through the throat of the machine and the spray gun to the surface of the carton. Allow to cool and bond. To meet the requirements of carton sealing also overcome the defects of traditional carton sealing.
The requirements of transportation cartons are to withstand changes in ambient temperature and air humidity and the inevitable roughness in handling, and the adhesive force of tape is poor and the tensile strength is low, and the adhesive force of oily cardboard or coated is weak, so it is difficult to meet the ideal transportation requirements. Therefore, compared with the adhesive tape, our hot melt adhesive highlights its advantages. Hot melt adhesive has strong penetration and good adhesion of wet material, and can play a physical and chemical bonding role between corrugated paper and lined cardboard. After bonding, the overall strength of the carton is enhanced, and it is not easy to deform and crack. And the hot melt adhesive coating system can be applied to different shapes of key parts. For example, the folding lid inside the carton can be coated with glue. In addition, due to the poor low temperature resistance of the self-adhesive tape, it is easy to produce glue if used in the cold climate in the north; Therefore, hot melt adhesive has a great demand in this regard, because it has good low temperature resistance and can withstand low temperatures.
Secondly, it has another advantage: long storage period, small occupation area, no special storage requirements; The storage period of tape is usually only about half a year and requires certain storage conditions, so it is easy to deteriorate. The above is about the demand and role of hot melt adhesive in the packaging industry.
