Abstract

The invention discloses a high-air-tightness pe packaging bag which comprises a pe wire drawing film layer positioned outside the pe packaging bag, a pe base film layer positioned inside the pe packaging bag and a glue layer for bonding the pe wire drawing film layer and the pe base film layer, wherein a plurality of tear lines are arranged on the pe wire drawing film layer at intervals and penetrate through the pe wire drawing film layer, and the thickness of the pe base film layer is not higher than 30 micrometers. The present case has the characteristics that the gas tightness is strong and easy tearing is kept simultaneously.

Description

High gas tightness pe wrapping bag

Technical Field

The invention relates to the technical field of environment-friendly packaging materials, in particular to a high-air-tightness pe packaging bag.

Background

The packing bag means a tape for packing various articles, so that the goods are conveniently transported and easily stored in the production flow process, and the product quality of the articles is ensured. At present, the packaging bag is widely used in daily life and industrial production. The pe plastic film is a colorless, tasteless, odorless and semitransparent nontoxic insulating material, so that the pe packaging bag made of the pe plastic film is safer and more environment-friendly.

Current pe wrapping bag generally only includes one deck pe base film, and pe base film one side is equipped with the tear line, opens the wrapping bag through this tear line, and a plurality of tear lines pierce through pe base film, make tear line position and can form ventilative gap, have influenced the gas tightness of pe wrapping bag from this.

In view of the above, the applicant has made an intensive study to solve the above problems and has made the present invention.

Disclosure of Invention

The invention mainly aims to provide a high-air-tightness pe packaging bag which has the characteristics of strong air tightness and easy tearing.

In order to achieve the above purpose, the solution of the invention is:

the utility model provides a high gas tightness pe wrapping bag, wherein, including lieing in the outside pe wire drawing rete of pe wrapping bag, lieing in the inside pe base rete of pe wrapping bag and being used for the gluey water layer of bonding the two, the interval is equipped with a plurality of tear lines on the pe wire drawing rete, and this tear line pierces through pe wire drawing rete, pe base rete thickness is not higher than 30 microns.

Furthermore, the plurality of tearing lines are arranged at equal length and equal intervals,

further, the ratio of the length of the single tear line to the spacing of the two tear lines is 3: 2.

further, the thickness of the pe-based film layer ranges from 25 microns to 30 microns.

After the structure is adopted, the high-air-tightness pe packaging bag comprises a pe base film layer, a glue layer and a pe wire drawing film, wherein the pe base film layer, the glue layer and the pe wire drawing film are arranged from the inside of the pe packaging bag to the outside of the pe packaging bag, the glue layer is used for bonding the pe base film layer and the pe wire drawing film, and the tearing line only penetrates through the outside pe wire drawing film and does not penetrate through the pe base film layer. Compared with the prior art, the technical effect is that the pe-based film layer positioned inside is kept complete, so that no gap is formed for air to enter, and the pe packaging bag has the advantage of higher air tightness; secondly, although the scheme has a three-layer structure, the thickness of the base film layer of pe is not more than 30 microns, and the thinner thickness is beneficial to tearing. In conclusion, the scheme has the characteristics of high air tightness and easiness in tearing.

In the figure: 1-pe wire drawing film layer; 11-tear lines; 2-glue layer; 3-pe base film layer.

Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following specific examples.

As shown in fig. 1 and 2, a high gas tightness pe wrapping bag, including lieing in pe wrapping bag outside pe wire drawing rete 1, lieing in pe base rete 3 of pe wrapping bag inside and being used for the two glue layer 2 of bonding, glue layer 2 can adopt green's starch glue or glutinous rice to glue, and pe wire drawing rete 1 adopts current wire drawing technology preparation for pe membrane, and pe material has tasteless nontoxic characteristic, uses safer environmental protection. Interval is equipped with a plurality of tear lines 11 on pe wire drawing rete 1, and this tear line 11 pierces through pe wire drawing rete 1, nevertheless do not pierce through pe base rete 3, make pe base rete 3 that is located inside keep intact, do not have the gap to supply the gas to get into, just so improved the gas tightness of wrapping bag greatly.

Simultaneously, pe base film layer 3 thickness range is not higher than 30 microns, is less than the thickness of the pe base film of current wrapping bag promptly, though like this pe base film layer 3 is not penetrated by tear line 11, but thinner thickness also is favorable to tearing open the wrapping bag, can also increase the compliance of wrapping bag.

Since too thin a thickness affects strength and load bearing, the applicant has determined through studies that the pe-based film layer 3 has a thickness in the range of 25-30 microns. The thickness of the pe base film layer is at least 25 micrometers, so that the moderate thickness ensures the bearing capacity of the packaging bag.

Preferably, the plurality of tear lines 11 are equally spaced and equal in length, so that the tear force is more uniform and the tear is easier to tear.

The length and arrangement of the tear lines also affect the tearing operation, and if the tear lines 11 are short in length and sparsely arranged, the package is relatively tight and is not easily torn, easily causing excessive force to damage the entire package. If the tear lines 11 are provided long and arranged densely, the connection is poor and is prone to accidental disconnection. More preferably, the applicant has further selected the length and arrangement of the tear lines 11 such that the ratio of the length L1 of a single tear line 11 to the spacing L2 of two tear lines 11 is 3: 2. the ratio of the length of the single tear line 11 to the spacing of the two tear lines is 3: 2, the packaging bag can be torn by the force just right after the use, and the packaging bag is not easy to damage.

The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications thereof by those skilled in the art should be considered as not departing from the scope of the present invention.
