Description

A kind of compound additive of high glaze transparent linear low density polyethylene film
Technical field
The present invention relates to a kind of high molecular material auxiliary agent, and in particular to a kind of high glaze transparent linear low density polyethylene is thin The compound additive of film.
Background technology
Linear low density polyethylene (LLDPE) has the excellent characteristics such as intensity height, good toughness, weather resistance be excellent, at present Most of traditional markets of polyethylene, including farm-oriented mulch, canopy film, various packaging film fields are penetrated into.With low density polyethylene (LDPE) (LDPE) compare, impact strength, tearing toughness and the chemicals-resistant corrosivity of LLDPE films significantly improve, still The turbidity of LLDPE films.Show that glossiness is not so good as LDPE.This is because its main chain is mainly linear structure, long-chain branch is less, makes Into LLDPE crystallinity is higher, crystal size is larger, therefore it is easier to cause to show coarse uneven and make superficiality in blown film It can be deteriorated.
With society, the development of science and technology, the comprehensive performance requirement to polyethylene film is higher and higher.The hair of food package film Exhibition trend is the existing high intensity of requirement packaging film, and has the good transparency and pliability, weatherability, the smell small and fast light, hot Ageing properties etc., with good processing performance when producing film, meet the processing request of low energy consumption, the film of production is wrapping Dress, carry, puncture-resistant, tear-proof in handling and storage.At present, the common industrial means of high-grade packaging film are that addition is a small amount of LDPE blending and modifyings, improve LLDPE surface propertys and the transparency.With above-mentioned composition prepare composite package film glossiness, Transparency, pliability, processing performance etc. have a preferable comprehensive performance, but in heat aging property, resistance to tearing, resist to fall The problem of marking impact strength etc. and go back Shortcomings, while also bringing process complications and cost increase.
The content of the invention
It is low that a kind of high glaze transparent linear is provided it is an object of the invention to overcome in place of the shortcomings of the prior art The compound additive of density polyethylene film.
