Abstract
The utility model discloses a kind of BOPET coated films of high-adhesiveness, including the upper BOPET base membrane layer, adhesive layer and lower BOPET base membrane layer set gradually；The upper surface of the upper BOPET base membrane layer is coated with PVOH coating, and the lower surface of the lower BOPET base membrane layer is equipped with succinic anhydride coating.Due to being provided with PVOH coating in the upper surface of upper BOPET base membrane layer in the utility model, the integral strength of coated film can be greatly improved, the lower surface of lower BOPET base membrane layer is provided with succinic anhydride coating, increase the binding force of coated film Yu packaged product, it adheres to closer, packages that rear surface is not blistering, and aesthetic effect is good, the class of packaged product is improved, the degree of recognition of consumer is further improved.
Description
Technical field
The utility model relates to a kind of BOPET coated films of high-adhesiveness.
Background technique
Currently, with the development of science and technology, the more and more extensive application of packaging material, many food or daily necessity are needing
The case where transporting for long-distance, or guaranteeing the quality for a long time, requires to be packaged by packaging material.
And the coated film flexible packing material of film production is coated using water-soluble polymer lotion, production technology is general
For：On basic material such as plastic film or thin slice, it is coated with one layer of 0.1g/m2~5g/m2's through sided corona treatment quantitative and even
Adhesive forms bonding adhesive layer, and such as solvent type or aqueous type adhesive, adhesive can play dope layer and polymer base
The effect of tight bond is adhered in material layer linking, then removes the solvent in adhesive through heated-air drying, above it quantitative and even
It is coated with one layer of 0.1g/m2~20g/m2 water-soluble polymer lotion, under certain process conditions, through infrared processing and hot air drying
It is dry to make its crystalline film, then accelerate its crystallization to be formed through cooling winding catalysis, become functional coated film.Interlayer adhesive
It uses, purpose is mainly to solve combining closely between basic material and coating, and enhancing attachment improves removing and heat seal strength
Effect is conducive to coated film production, the more requirement of adaptation product packaging.
Existing BOPET coated film, during being heat-shrinked due to it, low with the intensity of packaged product, binding force is poor, glues
Conjunction is not close, be easy to cause coated film surface blistering phenomenon, influences the appearance of product, reduces the class of product, so that consumption
Person's degree of recognition reduces.
Utility model content
The utility model aim is to provide a kind of BOPET coated film of high-adhesiveness in view of the defects existing in the prior art.
The utility model to achieve the above object, adopts the following technical scheme that：A kind of BOPET coated film of high-adhesiveness,
Including the upper BOPET base membrane layer, adhesive layer and lower BOPET base membrane layer set gradually；The upper surface of the upper BOPET base membrane layer applies
It is covered with PVOH coating, the lower surface of the lower BOPET base membrane layer is equipped with succinic anhydride coating.
Further, the upper surface of the PVOH coating is provided with super nano tin oxide particle layer.
Further, the partial size of the tin oxide particles in the super nano tin oxide particle layer is between 10-20nm.
The beneficial effects of the utility model：Due to being provided in the upper surface of upper BOPET base membrane layer in the utility model
PVOH coating can greatly improve the integral strength of coated film, and the lower surface of lower BOPET base membrane layer is provided with succinic anhydride and applies
Layer, increases the binding force of coated film Yu packaged product, and adherency is closer, packages that rear surface is not blistering, and aesthetic effect is good, mentions
The class for having risen packaged product further improves the degree of recognition of consumer.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Shown in Fig. 1, it is related to a kind of BOPET coated film of high-adhesiveness, including upper BOPET base membrane layer 1, the glue set gradually
Adhesion coating 2 and lower BOPET base membrane layer 3；Above-mentioned trilaminate material is made using co-extrusion technology through biaxial tension.Wherein, the upper BOPET
The upper surface of base membrane layer 1 is coated with PVOH coating 12, and the lower surface of the lower BOPET base membrane layer 3 is equipped with succinic anhydride coating 31.
In order to improve the intensity of coated film entirety, PVOH coating can be set in the upper surface of upper BOPET base membrane layer.In order to
Allow the binding force of coated film and packaged product higher when packaging, adhere to it is closer, can be in lower BOPET base membrane layer 3 when design
Lower surface is equipped with succinic anhydride coating 31.Due to being provided with succinic anhydride coating 31 in lower 3 lower surface of BOPET base membrane layer, increase
The binding force of coated film and packaged product, adheres to closer, packages that rear surface is not blistering, aesthetic effect is good, improves
The class of packaged product.
In addition, coating film surface is scratched in order to prevent, convenient for the packaging of product, set in the upper surface of the PVOH coating
It is equipped with super nano tin oxide particle layer.Preferably, the partial size of the tin oxide particles in super nano tin oxide particle layer is in 10-
Between 20nm.And due to the presence of super nano tin oxide particle layer, so that the surface hardness and stiffening property of coated film are more preferable, so that
The anti-scratch effect of coated film is more preferable, substantially increases the aesthetics of packaging product.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
