Abstract
The utility model discloses a kind of BOPP cigarette films of high-adhesiveness, including surface layer (1), intermediate layer (2) and the bottom (3) set gradually；The surface layer (1) is copolymerization PP layers, and the intermediate layer (2) is homopolymerization PP layer, and the bottom (3) is copolymerization PP layers；The lower surface of the bottom (3) is provided with succinic anhydride coating (31).Due to being provided with succinic anhydride coating in the lower surface of bottom in the utility model, cigarette film and the adhesion of cigarette case are added, adhesion is closer, it is non-foaming to package rear surface, aesthetic is good, improves the class of cigarette case, further increases the degree of recognition of consumer.
Description
Technical field
It the utility model is related to a kind of BOPP cigarette films of high-adhesiveness.
Background technology
Tobacco business once used multiple material on cigarette external packaging film, including glassine paper, PVC coated films,
PVDC coated films, BOPP cigarette films etc..BOPP cigarette films are because with good optical property, wider heat-sealing scope, higher heat-sealing
Intensity, stronger vapor water barriers ability, uniform thickness, wider shrinkage factor modification scope and good deflection etc. other
The incomparable characteristic of material, turn into the preferred material of cigarette package.
Existing BOPP cigarette films, poor with the adhesion of cigarette case during its thermal contraction, bonding is not close, easily makes
Cigarette-forming film surface blistering phenomenon, the outward appearance of product is influenceed, reduce the class of product so that consumer's degree of recognition reduces.
Utility model content
The purpose of the utility model is the BOPP cigarette films that a kind of high-adhesiveness is provided the defects of presence for prior art.
The utility model to achieve the above object, adopts the following technical scheme that：A kind of BOPP cigarette films of high-adhesiveness, including
Surface layer 1, intermediate layer 2 and the bottom 3 set gradually；The surface layer 1 is copolymerization PP layers, and the intermediate layer 2 is homopolymerization PP layer, described
Bottom 3 is copolymerization PP layers；Wherein, the lower surface of the bottom 3 is provided with succinic anhydride coating 31.
Further, the upper surface of the surface layer 1 is provided with super nano tin oxide particle layer 12.
Further, the particle diameter of the tin oxide particles in the super nano tin oxide particle layer 12 is between 60-80nm.
The beneficial effects of the utility model：Applied in the utility model due to being provided with succinic anhydride in the lower surface of bottom
Layer, adds cigarette film and the adhesion of cigarette case, and adhesion is closer, packages that rear surface is non-foaming, and aesthetic is good, improves perfume (or spice)
The class of cigarette case, further increase the degree of recognition of consumer.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Shown in Fig. 1, it is related to a kind of BOPP cigarette films of high-adhesiveness, including surface layer 1, intermediate layer 2 and the bottom set gradually
3；The surface layer 1 is copolymerization PP layers, and the intermediate layer 2 is homopolymerization PP layer, and the bottom 3 is copolymerization PP layers；Above-mentioned trilaminate material
It is made using co-extrusion technology through biaxial tension.
In order to make the adhesion of cigarette film and cigarette case higher in packaging, adhesion is closer, can be in the bottom 3 during design
Lower surface be provided with succinic anhydride coating 31.Due to being provided with succinic anhydride coating 31 in the lower surface of bottom, cigarette film is added
With the adhesion of cigarette case, adhesion is closer, packages that rear surface is non-foaming, and aesthetic is good, improves the class of cigarette case.
In addition, in order to prevent cigarette film surface to be scratched, it is easy to the packaging of product, is provided with the upper surface of the surface layer 1
Super nano tin oxide particle layer 12.Preferably, the particle diameter of the tin oxide particles in super nano tin oxide particle layer 12 is in 60-
Between 80nm.And due to the presence of super nano tin oxide particle layer 12 so that the case hardness of cigarette film and very property is more preferable so that
The anti-scratch effect of cigarette film is more preferable, substantially increases the aesthetic property of packaging product.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc., guarantor of the present utility model should be included in
Within the scope of shield.
