Abstract
The utility model discloses a kind of plastic packaging bag, comprise (2) bottom bag sidepiece (1), bag, bag top (3); It is characterized in that: described bag sidepiece (1) is provided with flange (4), bottom described bag, (2), bag top (3) are by being connected with bag sidepiece (1) with the mode that flange (4) seals.
Description
Technical field
The utility model relates to packaging field, specifically refers to a kind of plastic packaging bag.
Background technology
Existing plastic packaging bag structure as shown in Figure 1, to comprise bottom bag sidepiece 0.1, bag 0.2, bag top 0.3; During virtual package, bottom bag 0.2 with bag sidepiece 0.1 by sealing into bag like construction, then packed article is put into this bag like construction; Finally bag top 0.3 and bag sidepiece 0.1 are sealed by heat-sealing.
In virtual package process, packed article size and plastic packaging bag volume basically identical; Easily occur when packed article being put into plastic packaging bag because of firmly excessive or because of bag top 0.3 and bag sidepiece 0.1 seal time, packed article 0.2 will to collapse open with bag sidepiece 0.1 bottom bag.
Described as can be seen from above, the plastic packaging bag Problems existing of currently available technology is: the structure of existing plastic packaging bag easily breaks.
Summary of the invention
For the problems of the prior art, the invention provides the plastic packaging bag that a kind of sound construction should not break.
In order to achieve the above object, technical scheme of the present invention is: a kind of plastic packaging bag, comprises bottom bag sidepiece, bag, bag top; Described bag sidepiece is provided with flange, is connected bottom described bag with flange by heat-sealing; Described bag sidepiece bottom is provided with flange, by being connected with bag sidepiece with the mode that flange seals bottom described bag; Described bag sidepiece top is provided with flange, and described bag top is by being connected with bag sidepiece with the mode that flange seals.
Can find out that this practical tool has the following advantages according to such scheme: bag sidepiece upper and lower is equipped with flange, the scalable area of plastic packaging bag can be improved further by sealing with flange bottom bag, can effectively prevent because of firmly excessive, packed article collapses out bottom bag with bag sidepiece.
As preferably, described bag top is also connected by heat-sealing with flange, increases the pull resistance at bag top.
As improvement, described plastic packaging bag also comprises bottom the second bag, seals bottom described second bag with described flange, and bottom bag, bag top is also by being connected with bag sidepiece with the mode that flange seals; Adopt the design bottom two bag can improve the fastness of plastic packaging bag further.

Shown in figure: prior art: 0.1, bag sidepiece, 0.2, bottom bag, 0.3, bag top;
The present invention: 1, bag sidepiece, 2, bottom bag, 3, bag top, 4, flange, bottom the 5, second bag.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described.
Embodiment one:
As shown in Figure 2, a kind of plastic packaging bag, to comprise bottom bag sidepiece 1, bag 2, bag top 3; The upper/lower terminal of described bag sidepiece 1 is equipped with flange 4, bottom described bag 2 with bag sidepiece 1 lower end by after being connected with bag sidepiece 1 with the mode that flange 4 seals, described bag top 3 is also by being connected with bag sidepiece 1 with the mode that flange seals.
The benefit of such design effectively to improve the expansivity of bag, further increase the fastness of plastic packaging bag simultaneously, bag sidepiece 1 upper/lower terminal is equipped with flange 4, and maximizing ensures that plastic packaging bag not easily collapses out, and this plastic packaging bag can stand on ground or desktop simultaneously.
Embodiment two:
As shown in Figure 3, a kind of plastic packaging bag, to comprise bottom bag sidepiece 1, bag 2, bag top 3; The upper end of described bag sidepiece 1 is provided with flange, and bottom described bag, 2 still adopt directly and form that bag sidepiece 1 directly seals, and described bag top is by being connected with bag sidepiece with the mode that flange 4 seals.
Such design is with the expansivity of the plastic packaging bag not as good as embodiment one, but for general packed article bagging process, contriver finds that this design can well ensure that the anti-of plastic packaging bag breaks, and this plastic packaging bag can stand on ground or desktop simultaneously.
Embodiment three:
As shown in Figure 4, a kind of plastic packaging bag, to comprise bottom bag sidepiece 1, bag 2, bag top 3; The lower end of described bag sidepiece 1 is provided with flange 4, bottom described bag 2 be connected with bag sidepiece 1 by the mode sealed with the flange 4 of bag sidepiece 1 lower end after, described bag top 3 is still by being directly connected with the form that the upper end of bag sidepiece 1 directly seals.
Unapprehended people may think that between embodiment two with embodiment three, design plan essence is identical, actually this is not so.At the upper end of bag sidepiece or lower end design flange, that contriver draws through long-term experiment, be provided with flange to be mainly applicable to packed article volume in plastic packaging bag larger in the upper end of bag sidepiece, and packaging bag is when just can pack packed article, now adopt the upper end of bag sidepiece to be provided with flange and can play extraordinary anti-ly to break, and be provided with flange in the lower end of bag sidepiece when to be mainly applicable in plastic packaging bag the comparatively large or packed article heavier-weight of packed article volume, now adopt the lower end of bag sidepiece be provided with flange not only can prevent plastic packaging bag because of packed article volume larger, overexert when filling in and can also break by the heavier plastic packaging bag caused of mode packed article, this plastic packaging bag can stand on ground or desktop simultaneously.
Embodiment four:
As shown in Figure 5, a kind of plastic packaging bag, to comprise bottom bag sidepiece 1, bag 2, bag top 3; The upper/lower terminal of described bag sidepiece 1 is equipped with flange 4, bottom described bag 2 be connected with bag sidepiece 1 by the mode sealed with the flange of bag sidepiece 1 lower end after, described bag top 3 is again by being connected with bag sidepiece 1 with the mode that the flange of bag sidepiece 1 upper end seals, described plastic packaging bag also to comprise bottom the second bag 5, bottom described second bag, 5 seal with described flange 4, bottom bag 2, bag top 3 also by being connected with bag sidepiece 1 with the mode that flange 4 seals, this plastic packaging bag can stand on ground or desktop simultaneously.
Such design not only can reach the technique effect of embodiment one to three, further can improve the leak tightness of plastic packaging bag, fastness and water-proofness simultaneously.
Be understandable that, above about specific descriptions of the present invention, the technical scheme described by the embodiment of the present invention is only not limited to for illustration of the present invention, those of ordinary skill in the art is to be understood that, still can modify to the present invention or equivalent replacement, to reach identical technique effect; Needs are used, all within protection scope of the present invention as long as meet.
