Technical field
The present invention relates to the application that a kind of polyuinyl alcohol/polyamide is used for carton eye ring.
Background technology
Existing carton eye ring is typically made of two kinds of materials, and a kind of is the handle that plastics are made, one kind be non-woven fabrics/
The handle that plastic material is made.The handle that wherein plastics are made is because being usually to be molded, and volume is big, and hardness is harder, is installing
Artificial operation is needed when on to carton, it is difficult to realize automation, while can come after handle is installed in the front bulging of carton,
Add carton stack height and unstable, inconvenience stacking and transport, to the automatic operating of equipment are stacked in binning process
Influence is very big, and plastic handles are buckled in one end of carton medial pad, can also can destroy or scratch the production of packaging because hardness is higher
Product particularly flexible packing products.
And non-woven fabrics/plastic material handle is the reverse side for being affixed directly to carton, handle section carton front, it is necessary to
Reinforced sheet is fixed to paste handle, but because this material is without elasticity, the handle strip in carton front portion needs reserved one
Fixed length, and influence the stacking of carton.
In current global plastic packaging film in the market, the multilayer complex films ratio more and more higher with PA, present American-European, day
The PA consumptions on the ground such as this increase by more than 10% every year, and 30% is increased every year in the consumption of China, and PA is high in MULTILAYER COMPOSITE
10~25% are only accounted in barrier packaging film component, it is seen that usage amount is increasing in daily life for this packaging film, and
Can also more it popularize, it can make more than twice of the extended shelf-life of various food, the high-grade plastic packaging film of production is determined industry and existed
All it is extremely potential at present and in 10 years futures.
