Description
Technical field
The utility model relates to a kind of pre-coating film, specifically a kind of PET pre-coating film.
Background technique
PET film is since tensile strength is big, and the advantages that elasticity modulus is high, and impact resistant strength is big is in many necks such as industry, agricultural
Domain is widely applied.Pre-coating film is a kind of for printing the very important flexible packing material of product, and this product is using
Have the characteristics that in the process safety and environmental protection, it is easy to operate, energy-efficient, have excellent performance, market portion gradually mentions
It is high.Pre-coating film, which is overlayed on the printed matter surfaces such as paper printing object, packing material, can play the protections such as good waterproof, anti-tear work
With.Especially matt pre-coating film passes through to light diffusing reflection, feeling soft to people, deep, still, at matt pre-coating film
The packaging material of reason, usually because contacting with hard object, generates scuffing in transport and normal use process under external force
Or/and scratch, influence the beauty of packaging material.And PET pre-coating film is provided in the market there are easy to wear, the problems such as easy degumming,
The commonly used service life is not grown.
Utility model content
The purpose of this utility model is to provide a kind of PET pre-coating films, to solve the problems mentioned in the above background technology.
To achieve the above object, the utility model provides the following technical solutions:
A kind of PET pre-coating film, including PET transparent base film and PP non-woven substrate and setting in PET transparent base film and
White Reflection layer between PP non-woven substrate, the white Reflection layer are to apply made of polyester resin and titania powder
Layer；The other side of the PP non-woven substrate is provided with hot melt adhesive layer, is provided with adhesion promoting layer on hot melt adhesive layer；The PET is transparent
The other side of basement membrane is provided with scratch resistance coating.
As a further solution of the present invention: the white Reflection layer with a thickness of 3 μm~4 μm.
As a further solution of the present invention: the particle size of the PP non-woven substrate is 0.3 μm~0.7 μm.
Compared with prior art, the utility model has the beneficial effects that
1, the cementability between pre-coating film and printed matter can be improved in the utility model, makes the bonding force of this pre-coating film much
Greater than common pre-coating film, it has been suitably applied that postprocessing working procedures require, moistened surface tension is low and more difficult under high speed has covered
The printing of film.
2, scratching resistant is dispersed in polyaminoester emulsion (solution) and can improve paint film in the utility model scratch resistance coating
Hardness plays the role of resisting external force, reaches scratch resistant purpose；The smoothness for also increasing scratch resistance coating surface simultaneously, by
Active force can be distributed to bigger region when to external force, can also play scratch resistant purpose.
3, the PP non-woven substrate that the utility model uses plays a supportive role, and the particle for partial size less than 0.33 micron comes
It says, can almost pass through completely, not filtration.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model PET pre-coating film.
In figure: 1-PET transparent base film, 2- white Reflection layer, 3-PP non-woven substrate, 4- hot melt adhesive layer, 5- adhesion promoting layer,
6- scratch resistance coating.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, in the utility model embodiment, a kind of PET pre-coating film, including PET transparent base film 1 and PP non-woven fabrics
Base 3 and the white Reflection layer 2 being arranged between PET transparent base film 1 and PP non-woven substrate 3, the white Reflection layer 2
For coating made of polyester resin and titania powder；The other side of the PP non-woven substrate 3 is provided with hot melt adhesive layer
4, adhesion promoting layer 5 is provided on hot melt adhesive layer 4；The other side of the PET transparent base film 1 is provided with scratch resistance coating 6.
In the utility model embodiment, the hot melt adhesive layer 4 selects polyethylene copolymer, and adhesion promoting layer 5 is selected containing auxiliary
The utility model PET precoating can be improved by being coated with adhesion promoting layer 5 in 4 side of hot melt adhesive layer in the aqueous polyurethane emulsion of ingredient
Cementability between film and printed matter makes the bonding force of this pre-coating film be far longer than common pre-coating film, after being suitably applied
Manage that procedure calls, moistened surface tension is low and printing of the more difficult overlay film under high speed.
In the utility model embodiment, the white Reflection layer 2 with a thickness of 3 μm~4 μm.
In the utility model embodiment, the scratch resistance coating 6 is by thin polymer film and is coated on polymer film layer table
The scratch resistance varnish in face forms；The thin polymer film with a thickness of 50 μm~60 μm；The scratch resistance varnish includes: 60~90
The dispersions of polyurethanes of parts by weight；1~10 parts by weight scratching resistant；3~10 parts by weight matt auxiliary agents；0.05~0.2 parts by weight
Levelling wetting agent；0.1~0.5 parts by weight defoaming agent；And 1~15 parts by weight and crosslinking and curing agent.
In the utility model embodiment, the scratching resistant is silica, organic siliconresin, methyl methacrylate powder
