Application of hot-melt closure in Cartoner:
As a form of carton closure, hot-melt closure in Cartoner has partially substituted traditional tuck-in closure, and is applied in cartoning various medicines and foods. Due to the good packaging quality, pretty external appearance and low cost, hot-melt carton closure will expect wider application in Cartoning Machine.
1. Advantages of hot-melt carton closure
The hot-melt carton closure is bonded by cooling liquid hot melt adhesive from the hot melt adhesive mechanism that integrated with Cartoning Machine, which turns the hot melt adhesive into liquid and injects the liquid through its spray gun to the carton surface. It may both meet the requirements of carton closure in overall aspects and overcome the defects of other traditional carton closure.
2. Good packaging quality
Cartons to be transported must be able to withstand change of temperature and humidity as well as violent loading and unloading, but it is hard for tuck-in closure type to meet this requirement. Hot melt adhesive may bond well to cartons with strong permeability, so cartons sealed with hot melt adhesive are not liable to deformation or crack. Additionally, the application system of hot melt adhesive may press and apply the adhesive to key parts of various shapes, like the inner folded cover of cartons.
3. Anti-counterfeiting function
Hot-melt adhesive closure also provides anti-counterfeiting function, as the adhesive permeates into the carton and any attempt to open the carton will tear the fiber. However, for tuck-in type, it can be very easy to change articles contained in the carton and then close again without leaving conspicuous evidence.
