Application of a polyethylene polyamide composite film for carton handles

Abstract

The invention discloses application of a polyethylene and polyamide composite film to a paper box lifting handle. An adopted manufacturing technology comprises the steps that (1) raw materials, namely polyethylene and polyamide are put into an extruder to manufacture the polyethylene and polyamide composite film, and the mass ratio of PE to PA is (70-90):(10-30); and (2) the polyethylene and polyamide composite film is cut into strip-shaped lifting handle composite film bodies, the strip-shaped lifting handle composite film bodies are rolled up into composite film rolls and are connected into an automatic lifting handle penetrating device, through the automatic lifting handle penetrating device, the lifting handle composite film bodies are cut to be unified in length and then penetrate into lifting handle holes of a paper box, the two ends of the lifting handle composite film bodies penetrating into the lifting handle holes are pasted to the back surface of the paper box to manufacture the lifting handle made of the composite film. According to the application of the polyethylene and polyamide composite film to the paper box lifting handle, on the basis that the PE / PA composite film has strength and elasticity, automatic lifting handle adhering is achieved, the composite film is located on the outer side and the inner side of the paper box, the increased thickness is less than 1 mm, and paper box stacking is not influenced; and meanwhile, the composite film lifting handle is made of a flexible material, so that damage to a product in the paper box is avoided.

Description

technical field [0001] The invention relates to the application of a polyethylene polyamide composite film for carton handles. Background technique [0002] Existing carton handles are generally made of two materials, one is a handle made of plastic, and the other is a handle made of non-woven fabric / plastic material. Among them, the handle made of plastic is generally made of injection molding, which is bulky and hard. It needs manual operation when it is installed on the carton, and it is difficult to realize automation. At the same time, when the handle is installed, it will bulge out on the front of the carton. The stacking height of the carton is increased and the stacking is unstable during the packing process, which is inconvenient for stacking and transportation, which has a great impact on the automatic operation of the equipment. The plastic handle is buckled at one end of the inner liner of the carton, and it will be damaged or damaged due to its high hardness. P...

Among them, the handle made of plastic is generally made of injection molding, which is bulky and hard. It needs manual operation when it is installed on the carton, and it is difficult to realize automation. At the same time, when the handle is installed, it will bulge out on the front of the carton. The stacking height of the carton is increased and the stacking is unstable during the packing process, which is inconvenient for stacking and transportation, which has a great impact on the automatic operation of the equipment. The plastic handle is buckled at one end of the inner liner of the carton, and it will be damaged or damaged due to its high hardness. Products with scratched packaging, especially flexible packaging products

[0003] The handle of non-woven fabric / plastic material is directly pasted on the back of the carton, and the handle part is on the front of the carton, and a reinforcement sheet is needed to paste the handle to fix it, but because this material has no elasticity, the handle on the front of the carton Need to reserve a certain length, but affect the stacking of cartons
