Description
Technical field
The utility model relates to a kind of heat sealable antistatic PET gilding films of formula.
Background technique
PET film also known as high temperature resistance polyester film.It has excellent physical property, chemical property and dimensional stability, thoroughly
Bright property, recuperability, can be widely used in magnetic recording, photosensitive material, electronics, electric insulation, industrial film, package decoration,
The fields such as screen protection, the protection of optical grade specular surface.
Wherein, gilding film is also known as anodized aluminium (call of anodized aluminium is used more in printing industry), is one kind in diaphragm
One layer of metal foil is added with and manufactured thermoprint material through coating and vacuum evaporation on base.
Although PET itself for water, oxygen and carbon dioxide gas and barrier property with higher, for
Some pairs of barrier properties have the occasion of particular/special requirement, such as tomato product, the ripe product sensitive to trace oxygen, are only made with PET
It cannot be met the requirements for packaging material.As packaging material, heat-sealable is a kind of basic performance, and PET is due to molecule
Chain itself is rigid, and the thermal finalization in production process makes its crystallinity high and causes fusing point relatively high in addition, therefore, PET
Film itself is unable to heat-seal bond, largely limits the use of packaging material.
In existing PET gilding film, electrostatic phenomenon is generated by friction by PET gilding film, can often cause packaging material
The viscous ash in surface is contaminated, and influences to pack effect and beauty.Therefore, it is necessary to carry out antistatic treatment to PET gilding film.
Utility model content
The utility model aim is that provide a kind of antistatic PET of heat sealable formula in view of the defects existing in the prior art gold stamping
Film.
The utility model to achieve the above object, adopts the following technical scheme that：A kind of antistatic PET of heat sealable formula is gold stamping
Film, it is characterised in that：Including PET base membrane layer, aluminium coated, EVA adhesive layer and the gold stamping layer set gradually；The PET base membrane layer
Upper surface be coated with PVOH coating, the upper surface of the PVOH coating is provided with silver-plated copper powder conductive composite coating, described to scald
The lower surface of layer gold is equipped with the heat sealable coating made of thermoplastic elastic olefin polymer.
Further：The upper surface of the silver-plated copper powder conductive composite coating is provided with antimony tin particle and carbon particle is multiple
Close layer.
Further：The partial size of the antimony tin particle and the tin oxide particles in carbon particle composite layer is in 10-20nm
Between.
The beneficial effects of the utility model：Due to being set in the upper surface of upper PET base membrane layer in the utility model PET gilding film
PVOH coating has been set, the integral strength of gilding film can be greatly improved；Aluminium coated is increased, is made under the water oxygen rejection rate of gilding film
It is preferably minimized, close to zero, can preferably protect product.Due to being provided with the electropaining of silver-plated copper powder composite guide on PVOH coating
Layer can be very good to eliminate the electrostatic on PET gilding film, be easier to operate to when being used for product packaging, and electrostatic can be prevented tired
PET gilding film surface contamination caused by product, generates dust etc., improves the packaging effect and beauty of product.It should be noted that will
PVOH coating is arranged between PET base membrane layer and conductive composite coating, can to avoid PVOH coating is directly exposed to air and
By humidity, the oxygen-barrier property of PVOH is avoided to reduce.It is equipped in the lower surface of gold stamping layer by thermoplastic elastic olefin polymer system
At heat sealable coating, increase the tension of gold stamping film surface, when heat-sealing, the heat sealable coating of film be oppositely arranged, directly
Heat-sealing, tack is good, at low cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Shown in Fig. 1, be related to a kind of antistatic PET gilding film of heat sealable formula, including set gradually PET base membrane layer 1, aluminize
Layer 2, EVA adhesive layer 3 and gold stamping layer 4；The upper surface of the PET base membrane layer 1 is coated with PVOH coating 11, the PVOH coating 11
Upper surface be provided with silver-plated copper powder conductive composite coating 12, the lower surface of the gold stamping layer 4 is equipped with is gathered by thermoplastic elastic alkene
Close heat sealable coating 41 made of object.
It, can be significantly due to being provided with PVOH coating in the upper surface of upper PET base membrane layer in the utility model PET gilding film
Improve the integral strength of gilding film；Aluminium coated is increased, drops to the water oxygen rejection rate of gilding film minimum, close to zero, energy
Preferably protection product.Due to being provided with silver-plated copper powder conductive composite coating on PVOH coating, it can be very good elimination PET and scald
Electrostatic in golden film is easier to operate to when being used for product packaging, and the gold stamping film surface of PET caused by buildup of static electricity can be prevented dirty
Dye generates dust etc., improves the packaging effect and beauty of product.It should be noted that being arranged PVOH coating in PET base membrane layer
Between conductive composite coating, it can be directly exposed to air to avoid PVOH coating by humidity, avoid the oxygen of PVOH
Barrier property reduces.It is equipped with the heat sealable coating made of thermoplastic elastic olefin polymer in the lower surface of gold stamping layer, is increased boiling hot
When heat-sealing, the heat sealable coating of film is oppositely arranged for the tension on golden film surface, is directly sealed, tack is good, cost
It is low.Wherein, in order to reach optimum performance, the partial size of the antimony tin particle and the tin oxide particles in carbon particle composite layer exists
Between 10-20nm.
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.
