Application of Hot Melt Adhesive on Carton Packaging and Sealing

October 07, 2019

As a new type of carton and carton packaging sealing Tape, hot melt adhesive sealing tape has partially replaced traditional tying and tape packaging, and is used in carton packaging for various foods and cartons for wine, dairy products, etc. On the outer packaging. Due to the advantages of good packaging quality, beautiful appearance and low cost, the application of hot melt adhesive sealing tape will become more and more extensive.



Advantages of hot melt adhesive sealing tape 


Hot-melt adhesive sealing tape is the use of a hot melt machine to melt the hot melt adhesive into a liquid, and then through the throat of the hot melt machine and the spray gun, to the surface of the carton, and the hot melt adhesive is cooled to complete the bonding. It can meet the requirements of carton sealing tape and overcome the defects of the traditional carton sealing tape form.
Good packaging quality


Shipping cartons must be able to withstand temperature, humidity changes, and rough handling, but it is difficult to meet this requirement with tape because of its poor bond strength, low tensile strength, and poor adhesion to coated or oily paperboard.


The hot melt adhesive has a good binding force with the wet material, and has strong penetrating power, and simultaneously exerts physical and chemical bonding between the corrugated paper and the lining paper. The overall strength of the bonded carton is enhanced, and the carton is not easily deformed and cracked. In addition, the hot melt adhesive coating system can apply adhesive to key parts of various shapes, such as a folding cover in a carton.


Secondly, the dry tape is resistant to low temperature, and it is easy to open in the cold climate of the north; the hot melt adhesive has good low temperature resistance and can withstand low temperature of -40 °C. Moreover, the hot melt adhesive has a storage period of up to 2 years, and the storage area is small, and there is no special storage requirement; and the tape storage is only valid for half a year, and requires certain storage conditions, otherwise it is easy to deteriorate.
Hot melt adhesives also provide excellent anti-theft functionality, and any attempt to open the carton will tear the fibers as the adhesive penetrates into the corrugated. The tape can be cut with a knife, and the contents are removed unconsciously and sealed again.
low cost
The use of hot melt adhesive sealing tape speed is fast, the entire bonding process can be completed in only 1~3 seconds, suitable for mass production, low energy consumption and low cost. The standard corrugated box hot melt adhesive seal is about 32 yuan / 1000 boxes, which is the middle price of hot melt adhesive, and the middle price of the tape seal is about 120 yuan / 1000 cases.
If hot melt adhesive is used, the glue will not be stopped during the processing; the tape replacement needs to be stopped. Moreover, the partition may not be installed in the box, and the sealing tape strength is greater than the sealing tape strength of the inner partition when the tape is sealed, which can reduce the cost of the partition.


Beautiful appearance


Nowadays, merchants require packaging to convey products and corporate images through packaging design. Therefore, the fewer factors that hinder the appearance, the better. Tape often blocks images and interferes with the transfer of packaging information; hot melt adhesives are bonded between the flaps to provide greater display space.
