Description

The present invention relates to an envelope pasted packaging bag.

A packaging bag made of a packaging film generally has a longitudinal joint where both ends of the packaging film in the width direction are overlapped and joined over the entire length of the packaging film, and a predetermined length of the packaging film. It has a pair of lateral joints in which both ends in the length direction are overlapped and joined, and a main body located between the pair of lateral joints and accommodating the product.
As such packaging bags, there are provided a gassho pasted packaging bag in which the vertical joint portion protrudes from the main body portion, and an envelope pasted packaging bag in which the vertical joint portion constitutes a part of the main body portion.
Conventionally, most of the packaging bags in which products are enclosed on the market use gassho-pasted packaging bags.
In gassho adhesive packaging bags, the vertical joint is located at a different location from the main body, so the vertical joint is designed so that it can be easily broken even at the vertical joint where two packaging films are overlapped. Various structures have been proposed.
In the gassho adhesive packaging bag, an auxiliary joint is provided at a location on the main body adjacent to the widthwise end of one of the pair of lateral joints, and a notch for opening is provided in this auxiliary joint. The product can be easily removed from the packaging bag by breaking the main body through this opening notch (Patent Documents 1 and 2).

On the other hand, in a gassho-attached packaging bag, at a pair of horizontal joints, both ends of the vertical joint in the extending direction are folded down and joined to the horizontal joint, so that at the horizontal joint where the vertical joint is joined, A total of four packaging film portions are overlapped and joined (heat-sealed), and two packaging film portions are overlapped and joined (heat-sealed) at the other horizontal joint portions.
Therefore, when forming a horizontal joint, it is not possible to apply uniform pressure in the extending direction of the horizontal joint, and there is a problem that it is not possible to easily form a horizontal joint in a completely bonded state. Currently, efforts are being made to improve this.
In addition, in gassho paste packaging bags, the vertical joint is located on the main body and stands out, so the part of the main body where the vertical joint is not provided constitutes the front of the packaging bag, and the vertical joint is provided. The back surface of the packaging bag is divided into two parts by a vertical joint extending over the entire length of the main body. Moreover, there is a disadvantage in securing a large product advertising area that stimulates the desire to purchase the product.
Furthermore, gassho-stick packaging bags have a vertical joint that extends over the entire length of the main body and is conspicuous with respect to the main body, which is disadvantageous in terms of increasing the commercial value of the product sealed in the packaging bag. .
Therefore, as in Patent Documents 1 and 2, an auxiliary joint part is provided in the main body part adjacent to one of the pair of lateral joint parts in the envelope pasted packaging bag, and this auxiliary joint part is used for opening. It is conceivable to provide a notch and break the main body through this opening notch so that the product can be easily taken out from the packaging bag.

According to such an envelope pasted packaging bag, the two packaging film parts are overlapped and joined (heat-sealed) over the entire length of the pair of lateral joints in the longitudinal direction. Uniform pressure can be applied, which is advantageous in easily and reliably forming a perfectly bonded horizontal joint.
In addition, in envelope-stitched packaging bags, the vertical joint extends continuously with the main body, and the vertical joint forms a part of the main body. The vertical joint is eliminated, and the part of the main body where the vertical joint is located can also be used as the front of the packaging bag. Therefore, it is possible to secure a single large product advertising area on both the front and back of the packaging bag. It will be advantageous.
Furthermore, since the envelope-stitched packaging bag does not have a conspicuous vertical joint like the gassho-stitched packaging bag, it is advantageous in increasing the commercial value of the product enclosed in the packaging bag.
However, in an envelope pasted packaging bag, the vertical joint constitutes the main body, and two layers of packaging film are overlapped at the vertical joint, so one of the horizontal joints of the pair of horizontal joints An auxiliary joining part having an opening notch is provided at a location of the main body part adjacent to the opening, and even if the main body part is torn from the opening notch, the vertical joining part is not easily broken, making it difficult to open the packaging bag.
In this case, since the vertical joint of the envelope-stitched packaging bag constitutes the main body, applying the structure of the vertical joint of the gassho-stitched packaging bag to the vertical joint of the envelope-stacked packaging bag would not allow the vertical joint to The main body is likely to be torn at this point, which poses a problem in the durability of the envelope-attached packaging bag.
For these reasons, there are no envelope-stick packaging bags on the market that have an opening notch in the main body so that the product can be easily removed from the packaging bag.
The present invention has been devised in view of the above circumstances, and the present invention enables the product to be easily taken out from the packaging bag by breaking the main body through the opening notch provided in the main body, and to remove the product from the packaging bag. It ensures durability, easily and reliably forms a perfectly bonded horizontal joint, secures a large product advertising area on both the front and back of the packaging bag, and increases the commercial value of the product enclosed in the packaging bag. An object of the present invention is to provide an envelope-attached packaging bag which is advantageous in improving the quality of the product.

In order to achieve the above-mentioned object, the present invention provides a vertical joint portion in which the width direction film ends at both ends in the width W1 direction of a packaging film having a width W1 and a length L1 are overlapped and joined in the length L1 direction; A pair of lateral joints where longitudinal film ends at both ends of a predetermined length portion along the length L1 direction are overlapped and joined, and a location of the packaging film located between the pair of lateral joints. The main body part is formed of a certain main body film and has a hollow shape in which the product is housed, and the vertical joint part extends continuously with the main body film and constitutes a part of the main body film. , an envelope pasted packaging bag having a width W2 and a length L2 corresponding to the width W1 and length L1 of the packaging film, the main body portion being adjacent to one of the pair of horizontal joint portions; An auxiliary joining part is provided at an end in the width W2 direction of the main body part films facing each other, and an opening notch is provided in the auxiliary joining part, and the opening extends through the opening notch in the width W2 direction. At the location of the vertical joint including the imaginary line, at a location located on the opening notch side at the inner width direction film end located inside the main body part among the overlapped width direction film ends, the It is characterized by being provided with a rupture region that allows the longitudinal joint to be easily ruptured.

According to the present invention, when the main body part is torn from the opening notch and the torn part of the packaging film reaches the vertical joint part, the main body part is easily torn at the vertical joint part through the breaking area, and the packaging film is opened. Envelope-attached packaging bags can be easily opened from the notch.
In addition, since the break area is covered by the outer width direction film edge located outside the main body part among the width direction film ends overlapped at the longitudinal joint part, even if the break area is provided in the main body part. Regardless, it is advantageous in ensuring the durability of the envelope-attached packaging bag.
Therefore, according to the present invention, the product can be easily taken out of the packaging bag by breaking the main body through the opening notch provided in the main body, and a perfectly joined horizontal joint can be easily and reliably formed. Therefore, it is possible to provide an envelope-attached packaging bag which is advantageous in securing a large product advertising area on both the front and back sides of the packaging bag and increasing the commercial value of the product sealed in the packaging bag.
