Abstract

The invention discloses a PVC (Poly Vinyl Chloride) thermal contraction printing film, which is characterized in that 0.8-1.2 parts by weight of cation quaternary ammonium salt or nonionic esters antistatic agent are added into components; the added antistatic agent is firstly coupled and processed by coupling agent adaptive to the antistatic agent; in the film preparation process, the cation quaternary ammonium salt or a nonionic esters antistatic agent solution layer are applied to the surface of the film; and therefore the surface resistivity of the film is 108-1010 omega. Two different applied antistatic agents are applied to successively perform action. On the premise that other performances of the PVC thermal contraction printing film are guaranteed to be substantially unchanged, static charges in the production process are effectively prevented or eliminated from generating and accumulating, and the shortage brought by the static charges is avoided, and pollution on printing because the antistatic agent is excessively separated out can be avoided.

Description

technical field [0001] The invention is an improvement to the PVC heat-shrinkable printing film, and in particular relates to a PVC heat-shrinkable printing film which not only has antistatic function, but also does not reduce ink printing quality and rarely increases the cost. Background technique [0002] PVC heat-shrinkable printing film is a hard transparent PVC film, which is used for heat-shrinkable labels on product packaging after printing exquisite patterns. [0003] However, the surface resistivity of PVC heat shrinkable printing film is 10 14 ~10 16 Ω, has good insulation, and insulation leads to easy accumulation of static electricity. Objectively speaking, during the production and printing process of the film, the film will rub against multiple high-speed rollers, which is more likely to generate static electricity, and the accumulation of static electricity will easily lead to many quality problems. For example: the surface of PVC heat-shrinkable printing f...
