The invention discloses a PVC packing film and a production process thereof. The PVC packing film is prepared from raw materials of, by weight, 0.03-0.04 part of plasticizer, 7-9 parts of stabilizer,0.1-0.2 part of nanometer magnet powder, 0.15-0.22 part of nanometer activated carbon, 3-5 parts of titanium dioxide, 3.5-6 parts of fire retardant and 90-100 parts of PVC resin. S4, three sets of packing film rotary shafts obtained in S3 are installed at one end of a composite device, the upper and lower surfaces of a middle layer packing film are coated with transparent aqueous glue through a gluing structure in the composite device, and the other two layers of packing films are bonded to the upper and lower faces of the middle layer packing film through the transparent aqueous glue. The small amount of corresponding component exists in the packing films, does not influence transparency of the packing film and can absorb light, the black is high in light absorption capacity, the temperature rise is fast, and softness of the packing film is promoted. The smell of the packing film can be absorbed, and meanwhile the packing film can absorb the smell of the outside world during use. In addition, the magnet powder has a magnetism attraction function, and the packing film and irony metal can be bonded tightly.
Description
technical field [0001] The invention relates to the field of PVC packaging film processing, in particular to a PVC packaging film and a production process thereof. Background technique [0002] As a widely used packaging film, PVC packaging film has more stable and tidy packaging, and super waterproof effect. It has the characteristics of high tensile strength, high elongation, good self-adhesiveness, and high transparency. At the same time, there are some deficiencies in PVC packaging films in use: some PVC packaging films are very soft when used in summer, and harden in winter, unable to quickly absorb heat, hard texture, inconvenient to use, and have certain adverse effects on packaging. At the same time, PVC packaging film is easy to absorb dust and become opaque during use, and it is difficult to remove external impurities, which affects normal use. Moreover, the existing packaging film emits some odors during use and pollutes the air. In the process of packaging wit...
