BOPP pearlescent film as well as preparation method and application thereof

Abstract

The invention provides a BOPP pearlescent film as well as a preparation method and an application function thereof. The BOPP pearlescent film comprises an electrostatic adsorption layer and an antistatic layer, and a pearlescent core layer is further arranged between the electrostatic adsorption layer and the antistatic layer; the electrostatic adsorption layer comprises a polyolefin base material and an electret, and the polyolefin base material is a polyolefin copolymer or an elastomer; and the antistatic layer comprises homo-polypropylene, a permanent antistatic agent and a non-migration type opening auxiliary agent. The structure of the pearlescent film is refined and improved, so that the electrostatic adsorption surface of the pearlescent film has a lasting electrostatic effect; meanwhile, the anti-static surface has a good anti-static effect, meanwhile, good opening performance is kept, and the problem of mask adhesion can be well solved when the anti-static surface is used for preparing masks.

Description

technical field [0001] The invention relates to the technical field of film materials, in particular to a BOPP pearlescent film and its preparation method and application. Background technique [0002] As people's living standards are getting higher and higher, no matter women or men, more and more people pay attention to their appearance, and the demand for skin care is also increasing, so the market for facial masks is also growing day by day. A general facial mask consists of a pearlescent film base film and a mask paper layer. In practical applications, a layer of pearlescent film plus a layer of mask paper layer is put into the corresponding packaging bag, and then the relevant essence is injected into the packaging bag. , pick up the two layers when using it, and then peel off the pearlescent film. As a substrate, the pearlescent film itself has certain functions. When mass production, one side of the pearlescent film needs to have certain electrostatic adsorption prop...

AI Technical Summary

Problems solved by technology

The conventional pearlescent film on the market now uses ordinary homopolymer PP on the surface layer, and after corona is applied to the surface, the effect of electrostatic adsorption is realized, but due to the performance of homopolymer PP itself, such electrostatic effect is not durable, and Uneven, so it is often very unstable in the packaging process, which brings a lot of rework costs to the packaging factory. In addition, it has the side of repelling static electricity but also because of the unstable antistatic effect, it may also cause multiple groups (with one layer) Pearlescent film plus a layer of mask paper as a set) the mask combination will be put into the packaging bag, which will also cause rework
