Description
Technical Field
The utility model belongs to the technical field of the wrapping bag, concretely relates to wrapping bag.
Background
The wrapping bag can be used in daily life very often, adopt the film to make the bag body usually, the film is two usually, three limits of two bag bodies link together, and have a sack that can put into article, it is equipped with the strip of mutually supporting from the valve to be located the sack medial surface, form through integrative blow molding between valve and the film, because the thickness of valve between strip and the film is different, so form when valve and the integrative blow molding of film, can lead to the cooling method of processing to need to adopt air cooling's form, adopt air cooling's form can lead to the transparency of the film bag body to descend. In addition, when the self-sealing strips and the film are formed by integral blow molding, in order to ensure the sealing effect of the self-sealing strips, the material adopted by the film can incline towards the material limited by the technical requirements related to the self-sealing strips, so that the transparency of the film can be reduced, and further the transparency of the packaging bag can be reduced.
Disclosure of Invention
The utility model aims at having the above-mentioned problem to current technique, provided a wrapping bag, the utility model aims to solve the technical problem that: how to improve the transparency of the packaging bag.
The purpose of the utility model can be realized by the following technical proposal:
the utility model provides a packaging bag, is including having the open-ended bag body, and the bag body includes film piece one and film piece two, its characterized in that, and film piece one is located the opening part and is connected with film strip one, and film piece two is located the opening part and is connected with film strip two, and film strip one and two end-to-end of film strip are cyclic annular, are equipped with sealing strip one on the film strip one, are equipped with on the film strip two can be with sealing strip two of one looks lock.
The first film strip is connected to the first film strip, the second film strip is connected to the second film strip, the bag body can be independently produced with the first film strip and the second film strip, the first sealing strip and the second sealing strip are respectively arranged on the first film strip and the second film strip, therefore, materials used by the bag body do not need to incline to materials limited by the first sealing strip and the second sealing strip in the related technical requirements, the transparency of the bag body is further improved, and the bag body is connected with the first film strip and the second film strip in an independent production mode, so that the bag body can be cooled in a water-cooling mode after being blown out by a blow molding machine, and the transparency of the bag body can also be improved.
In the above-mentioned packaging bag, the first film strip and the first film sheet are overlapped with each other, the bottom of the first film strip is located on the inner side of the first film sheet and is connected with the first film sheet through hot pressing along the edge of the first film sheet, the second film strip and the second film sheet are overlapped with each other, and the bottom of the second film strip is located on the inner side of the second film sheet and is connected with the second film sheet through hot pressing along the edge of the second film sheet. The first film strip is located on the inner side of the first film sheet and is in hot-press connection with the edge of the first film sheet, and the second film strip is located on the inner side of the second film sheet and is in hot-press connection with the edge of the second film sheet, so that the outer surface of the bag body is smooth and flat.
In foretell wrapping bag, still be equipped with the sealing strip three that is located sealing strip one top on the film strip one, still be equipped with the sealing strip four that can with sealing strip three-phase lock on the film strip two. Through setting up sealing strip three and sealing strip four, cooperation sealing strip one and sealing strip two promote the sealed effect of wrapping bag.
In foretell wrapping bag, first recess has along its length direction on the sealing strip, and two lock joints of sealing strip are in first recess of sealing strip, and four last recesses of having along its length direction on the sealing strip are two, and three lock joints of sealing strip are in second recess. Because the sealing strip with the first groove and the sealing strip with the second groove are respectively positioned on the first film strip and the second film strip, when the packaging bag is opened, the force for separating the second sealing strip from the first groove and the force for separating the third sealing strip from the second groove are staggered, and the sealing performance of the packaging bag can be improved.
In the above packaging bag, a first convex line for preventing the first film strip from being attached to the inner side face of the second film strip is further arranged on the inner side face of the first film strip, and the first convex line is located above the third sealing strip. The setting of burr one makes the medial surface of film strip one and the medial surface of film strip two have the clearance between, and the user of being convenient for can be quick when the wrapping bag is opened to needs separates film strip one and film strip two.
In the above packaging bag, a second convex pattern for preventing the second film strip from being attached to the inner side surface of the first film strip is further arranged on the inner side surface of the second film strip, and the second convex pattern is located above the fourth sealing strip. The setting of burr two makes the medial surface of film strip two and the medial surface of film strip one between have the clearance, and the user of being convenient for can be quick when the wrapping bag is opened to needs separates film strip one and film strip two.
In the packaging bag, the top of the third sealing strip is provided with a plurality of indentations pressed downwards, the two sides of the third sealing strip deform along the indentation direction, and the indentations are distributed at intervals along the length direction of the third sealing strip. The indentation makes sealing strip three produce deformation, when the sealing strip three enters into the recess two of sealing strip four, can additionally extrude the recess and carry out the feedback to two pairs of fingers to can send crisp sound and inform the user, here compaction, secondly, when local not by the compaction, the local of taking place between the sealing strip three and the sealing strip four of deformation department has more obvious separation state, the observation of being convenient for.
Compared with the prior art, the packaging bag has the following advantages:
1. the bag body and the film strip are connected after being produced in a split mode, so that the bag body can be produced in a water-cooling mode, and the transparency of the bag body is improved.
2. And an indentation is arranged on the third sealing strip, so that feedback can be generated for a user when the third sealing strip enters the second groove.
