Abstract
The utility model provides a BOPP bag making membrane, belongs to the technical field of plastic film, and solves the technical problems that the conventional BOPP bag making membrane is sticky and easy to absorb static electricity. The BOPP bag making membrane comprises a central layer, an upper anti-static layer is fixed on the upper surface of the central layer, a lower anti-static layer is fixed on the lower surface of the central layer, an upper surface layer is fixed on the upper anti-static layer, a lower surface layer is fixed on the lower anti-static layer, and anti-seizing layers are fixed outside the upper surface layer and the lower surface layer. The BOPP bag making membrane is sticky and anti-static.
Description
Technical field
The utility model belongs to the plastic sheeting technical field, relates to a kind of bag film, particularly a kind of BOPP bag film.
Background technology
BOPP is the abbreviation of " Biaxially Oriented Polypropylene ", i.e. bidirectional stretching polypropylene film.Its production is that the melt of macromolecule polypropylene is at first made sheet material or thick film by long and narrow head, then in the stretching-machine of special use, under the speed of certain temperature and setting, simultaneously or the stretching carried out at vertical both direction (vertically, laterally) of substep, and the film of making through suitable cooling or heat treatment or special processing (such as corona, coating etc.).
BOPP is widely used and makes in the packaging bag, existing BOPP film in the market: disclose a kind of BOPP film (application number: 201020557524.8) such as Chinese patent, it is characterized in that: formed by the three-layer polypropylene resin, upper strata acrylic resin layer, middle level acrylic resin layer and lower floor's acrylic resin layer, converge curtain coating at three layers of T-shaped die head, through biaxial tension and moulding.
The BOPP film of this patent disclosure just is comprised of the three-layer polypropylene resin, because polyacrylic resin material itself has certain viscosity, cause the BOPP thin film exterior layer of this patent disclosure to have certain viscosity, with mutually adhesion of article, such BOPP film can't be used for making the packaging bag of various food easily; In addition, such BOPP film accumulates static easily in the process of making, and the BOPP film is when making various sack again, need to be at various patterns in the BOPP thin film exterior layer printing and literal, and static is a key factor that affects printing quality, cross strong static and can produce spark even, cause fire.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of BOPP bag film, and this BOPP bag film has characteristics inviscid, antistatic.
The purpose of this utility model can realize by following technical proposal: a kind of BOPP bag film, comprise sandwich layer, it is characterized in that, described sandwich layer upper surface is fixed with antistatic layer, described sandwich layer lower surface is fixed with lower antistatic layer, be fixed with upper epidermis on the described upper antistatic layer, be fixed with lower top layer on the described lower antistatic layer, all be fixed with adherent layer outside described upper epidermis and the lower top layer.
In above-mentioned BOPP bag film, the material of described upper antistatic layer and lower antistatic layer is ethoxylated fat family alkylamine.
In above-mentioned BOPP bag film, the material of described adherent layer is the ABS antitack agent.The chemistry of ABS antitack agent is by name: (Z, Z)-N, and N '-1,2-second two subunits are two-9-octadecylene acid amides.
In above-mentioned BOPP bag film, the material on described sandwich layer, upper epidermis and lower top layer is polypropylene.
In above-mentioned BOPP bag film, described upper epidermis is identical with the thickness on lower top layer, and the thickness on described upper epidermis and lower top layer is 30um～35um.
In above-mentioned BOPP bag film, the thickness of described sandwich layer is greater than the thickness of upper epidermis, the thickness 50um～55um of described sandwich layer.
Compared with prior art, the utlity model has following beneficial effect:
1, by increasing upper antistatic layer and lower antistatic layer, make BOPP bag film can with static, not improve printing quality and printing security.
2, by all be fixed with adherent layer outside upper epidermis and lower top layer, make BOPP bag film not have viscosity, can be used for packing various article, the scope of application is wider.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure, 1, sandwich layer; 2, upper antistatic layer; 3, lower antistatic layer; 4, adherent layer; 5, upper epidermis; 6, lower top layer.
The specific embodiment
Below be specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 1, a kind of BOPP bag film, comprise sandwich layer 1, described sandwich layer 1 upper surface is fixed with antistatic layer 2, described sandwich layer 1 lower surface is fixed with lower antistatic layer 3, be fixed with upper epidermis 5 on the described upper antistatic layer 2, be fixed with lower top layer 6 on the described lower antistatic layer 3, described upper epidermis 5 and the lower top layer 6 outer adherent layers 4 that all are fixed with.
The material of upper antistatic layer 2 and lower antistatic layer 3 is ethoxylated fat family alkylamine, the material of adherent layer 4 is the ABS antitack agent, the chemistry of ABS antitack agent is by name: (Z, Z)-N, N '-1,2-second two subunits are two-9-octadecylene acid amides, and the material on sandwich layer 1, upper epidermis 5 and lower top layer 6 is polypropylene.
Upper epidermis 5 is identical with the thickness on lower top layer 6, and the thickness on described upper epidermis 5 and lower top layer 6 is 30um～35um, and in the present embodiment, the thickness on upper epidermis 5 and lower top layer 6 is 33um;
The thickness of sandwich layer 1 is greater than the thickness of upper epidermis 5, the thickness 50um～55um of described sandwich layer 1, and in the present embodiment, the thickness of sandwich layer 1 is 52um; The thickness of adherent layer 4 is 10um, and the thickness of upper antistatic layer 2 and lower antistatic layer 3 is 12um.
Specific embodiment described herein only is to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has more used 1, sandwich layer; 2, upper antistatic layer; 3, lower antistatic layer; 4, adherent layer; 5, upper epidermis; 6, the term such as lower top layer, but do not get rid of the possibility of using other term.Using these terms only is in order to describe more easily and explain essence of the present utility model; They are construed to any additional restriction all is contrary with the utility model spirit.
