Abstract

The invention discloses a high operation lightweight 18micrometer BOPP cigarette packaging film and a preparation method thereof. The core layer of the packaging film selects a rigid increasing masterbatch with a benzene ring structure and a diester combined antistatic masterbatch, the upper surface layer selects a high viscosity silicone bead super-smooth masterbatch and an inorganic silica anti-adhesion masterbatch, the lower surface layer selects the high viscosity silicone bead super-smooth masterbatch and a composite anti-adhesion masterbatch, etc. The series of formula design enables theoperability and stability of the 18micrometer cigarette film comparable to those of 21micrometer cigarette films. On the basis of the high operability and high hardening resistance of the newly invented film, the thickness of the product is finally designed as 18 micrometers, thus changing the general tacit way of making up for quality with thickness in the industry, realizing the lightweight requirement put forward by cigarette factories many years ago, and achieving the original intentions of environmental protection and saving in the cigarette film industry.

Description

technical field [0001] The invention relates to the technical field of BOPP films, in particular to a lightweight 18-micron BOPP cigarette packaging film with high operability and a preparation method thereof. Background technique [0002] From the perspective of environmental protection and cost saving, tobacco factories have used 18 micron small packets of cigarette film accessories for many years. The standard small pack film for cigarettes is 21 microns. Everyone has a good grasp of the thickness of the cigarette film, but as long as it is switched to 18 microns, the production difficulty will increase, and the cigarette factory will also complain about the unstable quality of the film when it is used. will increase. Everyone has tried their best to improve the formula and control the quality, but the stability of the products produced has never been comparable to that of 21 microns. In the end, a tacit agreement was reached in the industry, that is, everyone tacitly m...
