Food pack at the bottom of double-layer square
Technical field
The utility model relates to a kind of packaging bag, is specifically related to food pack at the bottom of a kind of double-layer square.
Background technology
Existing food pack has transparent polybag and paper bag, the transparency of transparent polybag is good, oil removal, every powder (every
Slag), certain good water-proof effect be widely used, but the molding effect of transparent polybag is poor, is not easy to individually placed,
The good forming effect of paper bag, but its poor transparency, thus the state of food in being not easily seen bag, additionally, its oil removal,
The most very poor every powder (every slag), waterproof effect.
Summary of the invention
The problem existed for above-mentioned prior art, the utility model provides food pack at the bottom of a kind of double-layer square, this packaging bag
Good forming effect, and there is good oil removal, every powder effect, there is certain waterproof effect, moreover it is possible in being easy to observe bag
The state of food.
To achieve these goals, the utility model provides food pack at the bottom of a kind of double-layer square, including paper bag, transparent moulding
Pocket, the bottom of described paper bag is square, and the shape and size of described transparent polybag are suitable with described paper bag, transparent
Polybag to be positioned at paper bag internal and cover with paper bag and be integrated, described paper bag front lower central area offers window, institute
State top after paper bag and be provided with double faced adhesive tape.
In this technical scheme, by being provided with paper bag outside transparent polybag, and make bottom paper bag as square, the most not
Only make this packaging bag have a feature of good forming effect, and good oil removal can also be made it have, every powder (every slag) effect,
And there is certain water resistance;By being provided with window in paper bag front lower, the position of window correspondence polybag shows outside
Portion, thus user can observe the state of food in bag easily;After paper bag, top is provided with double faced adhesive tape, so,
This packaging bag in use, when making employment not eaten by the food in bag, can by by the upper edge of this bag along to
Folded behind, then by double faced adhesive tape, folded portion is pasted, it is thus possible to food falls into dust in avoiding bag, also can conveniently make
User is that row carries so that secondary eats.
Further, in order to improve the security of this packaging bag, reliability and the transparency, described transparent polybag uses food
Level BOPP film or PET film are made, and BOPP film is colourless, odorless, tasteless, nontoxic, and have high tensile, impact by force
Degree, rigidity, obdurability and the good transparency.PET film have excellence physical property, chemical property and dimensional stability,
The transparency, recuperability.
Further, in order to realize more easily the stickup folding position, described double faced adhesive tape is horizontally disposed with, its upper end distance
On paper bag, edge is 4cm.
Further, in order to be removed by the outer covering layer on double faced adhesive tape easily, left end and the right-hand member of described double faced adhesive tape are arc
Shape structure.Additionally, arcuate structure can also be until effect attractive in appearance.

Fig. 2 is the structural representation of another angle of the utility model.
In figure: 1, paper bag, 2, transparent polybag, 3, window, 4, double faced adhesive tape.
Detailed description of the invention
The utility model is described in further detail below.
As depicted in figs. 1 and 2, food pack at the bottom of a kind of double-layer square, including paper bag 1, transparent polybag 2, described paper
The bottom of bag 1 is square, the plastics that the shape and size of described transparent polybag 2 are suitable, transparent with described paper bag 1
Bag 2 is positioned at inside paper bag 1 and covers with paper bag 1 and is integrated, and described paper bag 1 front lower central area offers window 3,
After described paper bag 1, top is provided with double faced adhesive tape 4.By being provided with paper bag 1 outside transparent polybag 2, and make paper bag
Be square bottom 1, the most not only make this packaging bag have a feature of good forming effect, and can also make it have good oil removal,
Every powder (every slag) effect, also there is certain waterproof effect;By being provided with window 3 in paper bag 1 front lower, window 3 is right
The position answering polybag 2 shows in outside, thus user can observe the state of food in bag easily;At paper bag 1
Top is provided with double faced adhesive tape 4 below, so, this packaging bag in use, when making employment not eaten by the food in bag,
By the upper edge of this bag edge is folded rearwards, then by double faced adhesive tape 4, folded portion can be pasted, it is thus possible to avoid
In bag, food falls into dust, and also can facilitate user is that row carries so that secondary eats.
In order to improve the security of this packaging bag, reliability and the transparency, described transparent polybag 2 uses food-grade BOPP
Film or PET film are made, and BOPP film is colourless, odorless, tasteless, nontoxic, and have high tensile, impact strength, just
Property, obdurability and the good transparency.PET film have excellence physical property, chemical property and dimensional stability, the transparency,
Recuperability.
In order to realize more easily the stickup folding position, described double faced adhesive tape 4 is horizontally disposed with, on its upper end distance paper bag
Edge is 4cm.The most also the versatility of this packaging bag can be improved.
In order to be removed by the outer covering layer on double faced adhesive tape easily, left end and the right-hand member of described double faced adhesive tape 4 are arcuate structure.
Additionally, arcuate structure can also be until effect attractive in appearance.
