Description

A kind of multilayer heat shrinkable film
Technical field
The present invention relates to a kind of multilayer heat shrinkable film, belong to polymeric material field.
Background technology
Heat shrink films is for the sale of various products and transport, and its Main Function is to consolidate, hide and protect product.Shrink Film must have higher paracentesis resistance, good contractility and certain shrinkage stress.In contraction process, thin film can not produce Raw hole.Outdoor often it is applicable to, it is therefore desirable to add UV ultraviolet (UV) resistant agent due to shrink film.
PET: polyethylene terephthalate, English name: polyethylene terephthalate, is called for short PET. PET sheet has excellent characteristic (thermostability, chemical proofing.Obdurability, electrical insulating property, safety etc.), low price, So being extensively used as fiber, thin film, engineering plastics, polyester bottles etc..
PS: polystyrene Polystyrene, it is called for short PS, is a kind of water white thermoplastic.
Summary of the invention
The technical problem to be solved is to provide a kind of multilayer heat shrinkable film, a kind of Multi-layer thermal prepared by the present invention Shrink film, not only has higher hot strength, also has stronger shrinkage, improve barrier, has the heat of excellence Sealing property, the excellent transparency and toughness, and can recycle.
The technical scheme is that a kind of multilayer heat shrinkable film, including: top layer, centre Layer and hot sealing layer, described top layer and hot sealing layer are binded with intermediate layer from the both sides in intermediate layer mutually by bonding coat respectively, described in Interbed is made up of the raw material of following weight portion:
PET mylar 80-90 part, zinc stearate 1-10 part, epoxy soybean oil 1-10 part,
Described top layer is polypropylene (PP), very low density polyethylene (VLDPE), linear low density polyethylene (LLDPE), second One or more in alkene-vinyl acetate copolymer (EVA), ethylene ' alpha '-olefin plastomer copolymers, metallocene PE are mixed Compound,
Described hot sealing layer is made up of the raw material of following weight portion:
Polystyrene 100-200 part, dibutyl phthalate 1-5 part,
Described bonding coat is ethylene-vinyl acetate copolymer or maleic anhydride modified ethene polymers.
On the basis of technique scheme, the present invention can also do following improvement.
Further, the thickness in described intermediate layer is 1-10 micron.
Further, the thickness on described top layer is 1-10 micron.
Further, the thickness of described hot sealing layer is 20-40 micron.
Further, the thickness of described bonding coat is 1-5 micron.
Further, described bonding coat is ethylene-vinyl acetate copolymer (EVA), and the weight percent of vinylacetate contains Amount is 2%-20%, and density is 0.9-0.95g/cm3。
The invention has the beneficial effects as follows:
A kind of multilayer heat shrinkable film prepared by the present invention, not only has higher hot strength, also has stronger contraction Performance, improves barrier, has the heat sealability of excellence, the excellent transparency and toughness, and can recycle.
