Examples
Referring to fig. 1 to 2, a paper bag for packaging 10 in one embodiment of the present embodiment includes a surface paper sheet 11, a back paper sheet 12, and a release liner 13. The back sheet 12 is divided into a back portion 12a and a tongue portion 12b by a folding line L1. The release adhesive tape 13 comprises an adhesive tape 13a and release paper 13b, the adhesive tape 13a is adhered to the outer surface of the surface paper sheet 11, and the release paper 13b is adhered to the outside of the adhesive tape 13a and can be peeled off from the adhesive tape 13a. The surface layer paper sheet 11 is bonded to the surface layer paper sheet 11 by the bottom adhesive tape 14 and the two side adhesive tapes 15 and corresponds to the back sheet portion 12a so that the surface layer paper sheet 11 and the back layer paper sheet 12 enclose an open-topped accommodation space Q1; the bottom adhesive tape 14 extends to both sides in the width direction Y1 of the surface paper sheet 11, the side adhesive tape 15 extends in the height direction Y2 of the surface paper sheet 11, and a gap f1 exists between the bottom of the side adhesive tape 15 and the bottom adhesive tape 14, so that the surface paper sheet 11 and the backsheet paper sheet 12 define a passage opening K1 communicating with the accommodation space Q1 at a position corresponding to the gap f 1; the tongue portion 12b extends out of the surface paper sheet 11 and can be folded along the crease line L1 to the position corresponding to the release adhesive tape 13 for adhering to the adhesive tape 13a after the release paper 13b is peeled off.
The fold line L1 is a line at which the folding position is located, and may not be visible or actually present before folding.
The paper packaging bag 10 of the present embodiment is made of paper for packaging articles, is free from plastic contamination, and is environmentally friendly, and in use, the articles are put into the accommodating space Q1 of the paper packaging bag 10, and after the release paper 13b is peeled off, the tongue piece portion 12b is folded along the fold until the tongue piece portion 12b is bonded to the adhesive tape 13a, thereby sealing the paper packaging bag 10. Due to the existence of the channel opening K1, when articles are loaded, even if the top opening of the accommodating space Q1 is blocked or partially blocked by the articles, the gas in the accommodating space Q1 can be discharged through the channel opening K1, so that the influence on the loading of the articles is avoided; in addition, when a plurality of paper bags 10 for packaging containing articles are stacked and squeezed during packaging and transportation, redundant air in the accommodating space Q1 can be discharged through the channel opening K1, the occupied space is reduced, and transportation or storage is facilitated. Further, the paper bag for packaging 10 is provided with the release liner 13 on the outer surface of the surface paper sheet 11 (the surface located outside the containing space Q1) instead of the inner surface of the tongue-shaped portion 12b (the surface located inside the containing space Q1), and it is possible to prevent the article from being stuck with the adhesive tape 13a or being caught by the release liner 13 when the article is put in; in particular, when the paper packaging bag 10 is reused, the release paper 13b is peeled off at the time of previous use, and the adhesive tape 13a is exposed, and if the release tape 13 is provided on the inner surface of the tongue-piece portion 12b, it is very likely to stick to the article or the hand of the operator at the time of refilling the article, which may affect successful refilling of the article or even contamination of the article.
In this embodiment, the adhesive strength between the adhesive strip 13a and the surface paper sheet 11 is greater than the adhesive strength between the adhesive strip 13a and the tongue part 12b, i.e. when the tongue part 12b is separated from the surface paper sheet 11, the adhesive strip 13a remains adhered to the surface paper sheet 11 with a greater adhesive strength. The adhesive bond between the tongue portion 12b and the adhesive strip 13a is a separable weak adhesive bond, which means that the tongue portion 12b can be opened again without being broken after being adhered to the adhesive strip 13a for reuse. The adhesive strip 13a may be made of adhesive coated on the surface paper sheet 11, or may be a strip-shaped adhesive material.
In this embodiment, optionally, the bottom edge of the bottom adhesive tape 14, the bottom edge of the top sheet 11, and the bottom edge of the back sheet 12 coincide, and the outer side edge of the side adhesive tape 15, the outer side edge of the top sheet 11, and the outer side edge of the back sheet 12 coincide. In this way, the areas of the top sheet 11 and the back sheet 12 can be sufficiently utilized, and a large accommodation space Q1 can be obtained.
Optionally, the height of the gap f1 between the bottom of the side adhesive tape 15 and the bottom adhesive tape 14 is 3-10mm, so as to obtain a passage opening K1 with a proper size, and avoid that an excessively large gap f1 causes articles to fall out or an excessively small gap f1 affects the exhaust efficiency.
In this embodiment, the surface paper sheet 11 and the back paper sheet 12 are made of wood pulp base paper. The grammage (weight per square meter) of the wood pulp base paper can be 8-180 g, and the wood pulp base paper with the grammage of 17-45g is preferably adopted. The low gram weight wood pulp base paper is adopted, so that the manufacturing cost and the transportation cost of the product are reduced, and the portability of the product is improved. Alternatively, the surface paper sheet 11 and the back paper sheet 12 are made of highly transparent (transparency of 55-80%) or translucent (transparency of 45-55%) wood pulp base paper, so that bar code scanning can be conveniently realized without unpacking.
In addition, the paper bag 10 for packaging may be printed with patterns or characters to meet commercial needs such as brand publicity and product description.
Referring to fig. 3 to 4, another embodiment of this example provides a paper packaging bag 10a including a surface paper sheet 11, a back paper sheet 12, and a release liner 13. The back sheet 12 is divided into a back portion 12a and a tongue portion 12b by a folding line L1. The release adhesive tape 13 includes an adhesive tape 13a and a release paper 13b, the adhesive tape 13a is adhered to the inner surface of the tongue portion 12b, and the release paper 13b is adhered to the outside of the adhesive tape 13a and can be peeled off from the adhesive tape 13a. The surface layer paper sheet 11 is bonded to the surface layer paper sheet 11 by the bottom adhesive tape 14 and the two side adhesive tapes 15 and corresponds to the back sheet portion 12a so that the surface layer paper sheet 11 and the back layer paper sheet 12 enclose an open-topped accommodation space Q1; the bottom adhesive tape 14 extends to both sides of the width direction Y1 of the surface paper sheet 11, the side adhesive tape 15 extends along the height direction Y2 of the surface paper sheet 11, and a gap f1 exists between the bottom of the side adhesive tape 15 and the bottom adhesive tape 14, so that the surface paper sheet 11 and the back paper sheet 12 define a passage opening communicating with the accommodating space Q1 at a position corresponding to the gap f 1; the tongue portion 12b extends out of the surface paper sheet 11 and can be folded along the crease line L1 to a position corresponding to the release adhesive tape 13 for being adhered to the surface paper sheet 11 through the adhesive tape 13a after the release paper 13b is peeled off. Alternatively, the face sheet 11 and the back sheet 12 are made of highly transparent or translucent wood pulp base paper having a grammage of 17 to 45 g.
The paper packaging bag 10a in this embodiment is used for packaging an article, and in use, the article is placed in the housing space Q1 of the paper packaging bag 10a, the release paper 13b is peeled off, and then the tongue piece portion 12b is folded along the fold line until the tongue piece portion 12b is adhered to the adhesive tape 13a, thereby sealing the paper packaging bag 10 a. Due to the existence of the channel opening, when articles are loaded, even if the top opening of the accommodating space Q1 is blocked or partially blocked by the articles, the gas in the accommodating space Q1 can be exhausted through the channel opening, so that the influence on the loading of the articles is avoided; in addition, when a plurality of paper bags 10a for packaging containing articles are stacked and squeezed during packaging and transportation, redundant air in the accommodating space Q1 can be discharged through the passage opening, so that the occupied space is reduced, and the transportation or storage is facilitated.
