Description

Single-side opening rolling bag

Technical Field

The utility model belongs to the technical field of the sack, especially, relate to a unilateral opening rolling bag.

Background

Plastic bags for bagging vegetables and fruits are usually made of plastic films, and are rolled by a plurality of continuous plastic bags, the plastic bags are connected with each other by double-sided cutting marks, one end of each plastic bag is provided with a bag opening, and the other end of each plastic bag is required to be sealed electrically to form a solid plastic bag bottom so as to bear a certain weight of a packaged material. After the plastic bag is torn off along the cutting mark, the package can be placed only by rubbing the bag mouth with hands. Because the plastic bag is rolled up by the plastic film in a continuous cylindrical shape, no air exists in the bag, the plastic film is tightly attached, the bag opening is more tightly attached due to the cutting mark, and because of static electricity, the bag opening is very troublesome to rub, so that the time and labor are wasted when a user loads the packing materials, and the single-hand operation cannot be realized.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a unilateral opening rolls up bagging-off, aims at solving the plastic packaging bag among the prior art when packing article, wastes time and the hard technical problem again.

In order to achieve the above object, an embodiment of the present invention provides a single-side opening rolling bag, which includes a plurality of continuous rolling bags, a pre-tearing line is disposed between two connected bags, and one end of each bag, which is provided with the pre-tearing line, is a bag opening, one side of each bag is provided with a broken open edge and a folding line located below the open edge, the open edge is formed by a cutting mark, and a folding portion which is folded outwards is formed between the folding line and the open edge; each the bottom of wrapping bag all is equipped with strengthens sealing, strengthen sealing edge the width direction of wrapping bag extends to the both ends of wrapping bag.

Optionally, the distance from the open edge to the crease line is greater than the length of the reinforced seal.

Optionally, the folding line and the opening edge are both perpendicular to the side edge of the packaging bag.

The embodiment of the utility model provides an above-mentioned one or more technical scheme in unilateral opening package bag has one of following technological effect at least: the utility model discloses bagging-off is rolled up to unilateral opening tears the one side that the line is located the wrapping bag in advance, opens the limit and turns over a another side that the trace is located the wrapping bag to open the limit and tear the same level setting of line in advance. Because the turnover part is turned over outwards, the condition that the opening edge is easily adhered to the surface provided with the pre-tearing line under the influence of static electricity can be avoided, articles can be conveniently bagged through the bag opening, and the bag can be packed by one hand, so that the bag is very convenient.

The specific meaning of the above terms in the embodiments of the present invention can be understood by those skilled in the art according to specific situations.

In an embodiment of the present invention, as shown in fig. 1 to 3, a single-side opening rolling bag is provided, which comprises a plurality of continuous rolling bags 10, two continuous pre-tearing lines 20 are provided between the bags 10, the pre-tearing lines 20 vertically extend to both sides of the bags 10 along the width direction of the bags 10, and the bags 10 can be easily separated by the pre-tearing lines 20. And one end of each packaging bag 10 provided with the pre-tearing line 20 is a bag opening 11. The one side of wrapping bag 10 is equipped with the limit 12 of opening of disconnection and is located open the crease 13 of limit 12 below, it forms through cut 14 to open limit 12, and the maximum length of opening limit 12 is the width of wrapping bag 10, also can be half of wrapping bag 10 width, because open limit 12 passes through cut 14 and forms, if the length of opening limit 12 is the half of wrapping bag 10 width, the one end of opening limit 12 is cut 14 to the other end of wrapping bag 10, and convenient to use person can easily expand opening limit 12 with the hand. Is convenient for bagging the articles. A folding part 15 which is folded outwards is formed between the folding line 13 and the open edge 12; each the bottom of wrapping bag 10 all is equipped with strengthens sealing 16, strengthen sealing 16 edge the width direction of wrapping bag 10 extends to the both ends of wrapping bag 10, tear line 20 in advance and be located the bottom of strengthening sealing 16, so, when tearing continuous wrapping bag 10, fragile continuous wrapping bag 10.

Specifically, the pre-tear line 20 is located on one side of the bag 10, the open edge 12 and the crease 13 are located on the other side of the bag 10, and the open edge 12 is located at the same level as the pre-tear line 20, so that the opening of the torn bag 10 is flush. Because the folding part 15 is folded outwards, the situation that the opening edge 12 is easily adhered to the surface provided with the pre-tearing line 20 under the influence of static electricity can be avoided, articles can be conveniently bagged through the bag opening 11, and the bagging can be operated by one hand, so that the bag is very convenient.

In another embodiment of the present invention, as shown in fig. 1 and 3, the distance from the opening edge 12 to the crease line 13 is greater than the length of the reinforced seal 16. Specifically, the length of the flap 16 and the flap 1615 are slightly longer, so that the open edge 12 is not easily attached to the package 10.

In another embodiment of the present invention, as shown in fig. 1 to 3, the folding line 13 and the open edge 12 are perpendicular to the side of the packing bag 10. Specifically, the folding mark 13 and the opening edge 12 are arranged in parallel, the opening of the torn packaging bag 10 is flush,

in another embodiment of the present invention, as shown in fig. 1 to 3, the length of the packing bag 10 is 100mm to 800mm. Specifically, the length of each bag 10 is preferably 400mm, so as to ensure that the rolled bags 10 are consistent in specification.

In another embodiment of the present invention, as shown in fig. 1 to 3, the width of the packing bag 10 is 80mm to 700mm. In particular, the width of each bag 10 is preferably 300mm, ensuring that the rolled bags 10 are of consistent size

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
