Abstract

The invention relates to a windowing packaging bag which comprises a bag body. The inner layer of the bag body is wrapped with a layer of CPP film and is formed by a bag body front face, a bag body back face, two bag body side faces and a bag body bottom face in a sealed packaging manner; an opening is formed in the bag body front face which is provided with a transparent layer used for sealing the opening; and a first tearing line is arranged on the bag body front face along the edge of the lower portion of the opening, and the length of the first tearing line is at least one third of the perimeter of the opening. Through the arrangement of the transparent layer, situations inside the packaging bag can be observed through the transparent layer, and the packaging bag can be checked. Meanwhile, through the arrangement of a pulling strip on the side edge of the transparent layer, when objects in the packaging bag are fewer, the pulling strip can be directly torn open; as the length of the pulling strip is one third of the perimeter of the opening, an opening formed after the pulling strip is torn open completely allows the palm to be inserted therein for object taking, and the objects at the bottom of the packaging bag can be taken out very conveniently compared with the manner that the objects are taken out from the opening.

Description

One kind windowing packaging bag

Technical field

The present invention relates to packaging bag field, especially a kind of windowing packaging bag.

Background technology

Packaging bag, is service life ratio using the benefit of plastic packaging bag for device edible article or small articles etc. It is longer, cost-effective and lightweight.

In prior art, in plastic packaging bag product, directly to purchase, the internal layer of packaging bag is covered with one to bag stock material Layer CPP films, and need to use duroplasts tie rod when packaging bag is torn, the outer layer of sack is pulled open by force by tie rod, Throw away by after pulling open, the extremely difficult degraded of such duroplasts tie rod, and seldom or do not recycle, therefore the increasing of cost can be caused Plus the increase with production technology, while easily causing the pollution of environment and the waste of material.

Simultaneously packaging bag function of the prior art is more single.

The content of the invention

Present invention mainly solves technical problem be that a kind of windowing packaging bag is provided.

The present invention for solve the technical scheme that adopts of above-mentioned technical problem for：

One kind windowing packaging bag, includes bag, and bag internal layer is covered with one layer of CPP film, and bag is by before bag, after bag The encapsulation of face, two bag sides and bag sealing bottom surface is formed, and opening is offered before the bag, and before the bag use is provided with In the hyaline layer of sealing opening；The first tearing line is provided with along lower opening portion edge before the bag, the first tearing line length is extremely It is less 1/3rd of aperture perimeter；

The first tearing line side is provided with and identical second tearing line parallel with the first tearing line, first tearing line and second Tie rod is constituted between tearing line.

Further, the hyaline layer is identical with opening shape and the hyaline layer area is more than aperture area, described Hyaline layer is on the inner surface before bag；

The hyaline layer edge is provided with raised line, and the raised line length is at least 1/3rd of aperture perimeter and puts down with tie rod OK；Inner surface before the bag is provided with the recessed bar supporting with raised line, and the raised line engages composition sealing strip with recessed bar；Institute State raised line be with the cross sectional shape of recessed bar it is snakelike.

Further, described tie rod one end is provided with pull handle, and pull handle line is formed between the pull handle and bag.

Further, the material of the hyaline layer is transparent polyethylene.

Further, the raised line is coated with damping material with recessed bar surface.

Beneficial effects of the present invention are：

By the setting of hyaline layer, situation inside packaging bag can be observed by hyaline layer, packaging bag can be checked. Simultaneously by the setting of hyaline layer side tie rod, tie rod can be directly torn when article is less in packaging bag, because tie rod Length is 1/3rd of aperture perimeter, tears the fully sufficient palm insertion of the opening formed after tie rod and takes thing, compared with from opening Can realize very easily taking out the article of packaging bag bottom.

On and the inner surface that is arranged on before bag bigger than opening by hyaline layer, after tie rod is torn, can be by saturating The sealing strip that the raised line arranged on bright layer is constituted with recessed bar realizes resealing before bag, realizes the reuse of bag.

It is snakelike by the way that raised line and recessed bar section are set to, it is possible to achieve more it is close connection and sealing, raised line with Recessed bar is difficult for drop-off separate.

Description of the drawings

Fig. 1 is a kind of structural representation of specific embodiment of the invention.

Fig. 2 is the structural representation in a kind of specific embodiment of the invention before bag with hyaline layer.

Fig. 3 is the sectional view of raised line and recessed bar in a kind of specific embodiment of the invention.

In figure：1 is that before bag, 2 is hyaline layer, and 3 is the first tearing line, and 4 is the second tearing line, and 5 is tie rod, and 6 is raised line, 7 For recessed bar, 8 is opening, and 9 is pull handle.

Specific embodiment

Below in conjunction with the accompanying drawings the present invention is further elaborated.

One kind windowing packaging bag, includes bag, and bag internal layer is covered with one layer of CPP film, and bag is by 1, bag before bag Below, two bag sides and the encapsulation of bag sealing bottom surface is formed, and opening 8 is offered before the bag, is set before the bag Have for the hyaline layer 2 of sealing opening；The first tearing line 3, first tearing line are provided with before the bag along lower opening portion edge Length is at least 1/3rd of aperture perimeter；

First tearing line side is provided with and identical second tearing line 4 parallel with the first tearing line, and first tearing line is torn with second Tie rod 5 is constituted between line.

Hyaline layer is identical with opening shape and the hyaline layer area is more than aperture area, and the hyaline layer is located at bag On inner surface above；Hyaline layer edge is provided with raised line 6, the raised line length be at least 1/3rd of aperture perimeter and with drawing Bar is parallel；Inner surface before the bag is provided with the recessed bar 7 supporting with raised line, and the raised line engages composition sealing with recessed bar Bar；The raised line is snakelike with the cross sectional shape of recessed bar.

Tie rod one end is provided with pull handle 9, and pull handle line is formed between the pull handle and bag.

The material of hyaline layer is transparent polyethylene；Raised line is coated with damping material with recessed bar surface.

By the setting of hyaline layer, situation inside packaging bag can be observed by hyaline layer, packaging bag can be checked. Simultaneously by the setting of hyaline layer side tie rod, tie rod can be directly torn when article is less in packaging bag, because tie rod Length is 1/3rd of aperture perimeter, tears the fully sufficient palm insertion of the opening formed after tie rod and takes thing, compared with from opening Can realize very easily taking out the article of packaging bag bottom.It is bigger than opening and in being arranged on before bag by hyaline layer On surface, after tie rod is torn, the sealing strip that can be consisted of with recessed bar the raised line arranged on hyaline layer is realized before bag Reseal, realize the reuse of bag.
