Description

Packaging materials and packaging materials

The present invention relates to packaging materials and packaging materials.

There is known a packaging material for packaging articles, comprising: a main body sheet; and a strip for opening, which is adhered to the main body sheet in such a way that one direction becomes the longitudinal direction. In this packaging material, the main body sheet can be divided in the other direction intersecting with the above-mentioned one direction by cutting the main body sheet along the width direction of the strip body for opening (refer to Patent Document 1). ,2). Then, an article package is formed by wrapping the article with the packaging material.

When the packaging material is removed from the article in the state where the article packaging body is formed, the main body sheet is cut along the strip for opening at positions on both sides in the width direction of the strip for opening. Thereby, the strip-shaped region extending in the one direction is separated from the body sheet, and one side and the other side of the body sheet in the other direction remain on the article side. The wrapping material can then be removed from the article by pulling in such a way that one side and the other side of the body sheet remaining on the side of the article are moved away from each other.

However, in recent years, there has been a demand for the operation of removing the packaging material from the article by pulling with a smaller force so that one side and the other side of the main body sheet remaining on the article side can be pulled apart as described above.

Therefore, an object of the present invention is to provide a packaging material which can be removed from an article with a smaller force, and a packaging material raw material for manufacturing the packaging material.

The packaging material of the present invention comprises: a main body sheet, and a strip for opening that is adhered to the main body sheet in such a way that one direction becomes the longitudinal direction,

Wherein, the width of the aforementioned strip for unsealing is 10 to 25 mm,

When two imaginary lines extending in the longitudinal direction of the strip for unsealing are set at positions more inward than both end edges in the width direction of the strip for unsealing and in the vicinity of the two end edges, the At least a part of the two end regions formed between the two imaginary lines and the two end edges in the width direction of the strip for unsealing are adhered to the body sheet along the length direction of the strip for unsealing.

According to this structure, the width|variety of the strip body for opening is in the said range. In addition, at least a part of each of the two end regions is adhered to the body sheet along the longitudinal direction of the strip for opening. Thereby, when the main body sheet is cut along the strip for unsealing at the positions on both sides of the strip for opening on the main sheet in a state where the goods are packaged with the packaging material to form the packaging body of the goods, it is possible to prevent the damage on the main sheet from being damaged. The case where the cutting positions on both sides of the strip for unsealing advance to the inner side than the regions at both ends in the strip for unsealing. Therefore, borrow The band-shaped region (hereinafter also referred to as a separation region) formed by cutting the body sheet is separated from other regions with a relatively wide width. Thereby, since the area of the portion of the main body sheet remaining on the article side is relatively small, the operation of removing the portion of the main body sheet remaining on the article side from the article can be performed with a smaller force.

The two imaginary lines can be set at positions 4 mm inward from both end edges in the width direction of the strip for opening.

According to this configuration, by setting two imaginary lines at positions 4 mm inward from both end edges in the width direction of the strip for opening, the separation region of the main body sheet is separated from other regions with a wide width. Thereby, since the area of the portion of the body sheet remaining on the article side becomes smaller, the operation of removing the portion of the body sheet remaining on the article side from the article can be performed with a smaller force.

At least one of the two end edges in the width direction of the strip body for unsealing can be adhered to the body sheet as a whole along the longitudinal direction of the strip body for opening.

According to this structure, at least one of the both end edges in the width direction of the strip for unsealing is adhered to the main body sheet as a whole along the longitudinal direction of the strip for unsealing. Thereby, since the cutting position of the main body sheet can be prevented from advancing to the inner side of the end edge in the strip body for unsealing, the strip-shaped separation region in the main body sheet is separated from other regions by a wider width. Thereby, since the area of the main body sheet remaining on the article side becomes smaller, the operation of removing the portion of the main body sheet remaining on the article side from the article can be performed with a smaller force.

The aforementioned strip for opening can be adhered to the aforementioned main body sheet as a whole.

According to this configuration, the entirety of the strip for unsealing is adhered to the body sheet, whereby the rigidity of the overlapping region between the body sheet and the strip for unsealing in the packaging material increases. Therefore, even when the body sheet is cut on both sides of the unsealing strip of the body sheet, the force is applied toward the center side in the width direction of the unsealing strip. In addition, the overlapping area of the main body sheet and the strip for opening can also be suppressed from being bent. Thereby, the cutting of the main body sheet can be performed smoothly.

The packaging material raw material of the present invention is a packaging material raw material formed in a long strip shape extending in one direction and wound in the above-mentioned one direction,

The system is provided with: a main body sheet raw material, which is formed into a long strip extending in the aforementioned direction; and two strip raw materials for opening, which are formed in a long strip shape extending in the aforementioned one direction and are adhered to the aforementioned main body sheet original. material,

Wherein, the above-mentioned two strip raw materials for unsealing are arranged at intervals in the width direction of the above-mentioned main body sheet raw materials,

The width of the raw material of each strip for unsealing is 10 to 25 mm.

Two imaginary lines extending in the longitudinal direction of each strip raw material for unsealing are located at positions more inward than the both end edges in the width direction of each raw material for unsealing and in the vicinity of the two end edges When set on each strip material for unsealing, the two ends formed between the two imaginary lines set on each strip material for unsealing and both ends in the width direction of each strip material for unsealing At least a part of the outer region is adhered to the main body sheet material along the longitudinal direction of the strip body material for unsealing.

According to this configuration, the packaging material is cut in the longitudinal direction between the two strips for opening and the packaging material is cut in the width direction, whereby the following packaging material can be formed, which is provided with the main body sheet material. The formed body sheet, and the unsealing strip formed from the raw material of the strip body for unsealing and adhered to the body sheet in such a manner that one direction becomes the longitudinal direction.

Then, in the packaging material, the strip system for opening has a width corresponding to the width of the original strip body for opening. In addition, the tape system for opening has both end regions. At least a part of each of the two end regions is adhered to the body sheet along the longitudinal direction of the strip for opening.

Thereby, when the main body sheet is cut along the strip for unsealing at the positions on both sides of the strip for opening on the main sheet in a state where the goods are packaged with the packaging material to form the packaging body of the goods, it is possible to prevent the damage on the main sheet from being damaged. The case where the cutting positions on both sides of the strip for unsealing advance to the inner side than the regions at both ends in the strip for unsealing. Therefore, the band-shaped region (hereinafter also referred to as a separation region) formed by cutting the body sheet is separated from other regions with a relatively wide width. Thereby, since the area of the portion of the main body sheet remaining on the article side is relatively small, the operation of removing the portion of the main body sheet remaining on the article side from the article can be performed with a relatively small force.

Moreover, in the packaging material raw material comprised as mentioned above, the width|variety of each of the two strip raw material for opening is in the said range. In addition, at least a part of each of both end regions is adhered to the main body sheet material along the longitudinal direction of the strip material for opening. Thereby, when the packaging material raw material is wound in the longitudinal direction of the main body sheet raw material and formed into a roll shape, since the respective strip body raw materials for unsealing are easily overlapped each time the winding is performed, the packaging material can be stably wound and packaged. raw material.

In addition, by sticking at least a part of both end regions to the main body sheet material, when winding the packaging material material, it is possible to prevent the both ends of each strip material for opening in the width direction from being floated. . This can prevent the occurrence of wrinkles at both ends in the width direction of each strip material for opening.

In addition, when winding the raw material of the packaging material, a stronger tension is applied to the area having each raw material of the strip for opening than other areas. Therefore, by making the width of each strip material for unsealing relatively wide as in the above-mentioned range, the tension at the time of winding the packaging material material can be dispersed, and the operation of winding the packaging material material can be easily performed.

The two imaginary lines can be set at positions 4 mm inward from both end edges in the width direction of the strip raw material for unsealing.

According to this configuration, by setting two imaginary lines at positions 4 mm inward from both end edges in the width direction of the raw material for unsealing, it is possible to more effectively prevent each Both ends in the width direction of the raw material of the strip for opening are in a floating state. This can more effectively prevent the occurrence of wrinkles at both ends in the width direction of each strip raw material for opening.

At least one of the two end edges in the width direction of at least one of the two strip raw materials for unsealing can be adhered to the body sheet raw material as a whole along the longitudinal direction of the strip raw materials for unsealing.

According to this configuration, at least one of the both end edges in the width direction of at least one of the two strip raw materials for unsealing is adhered to the body sheet raw material as a whole along the longitudinal direction of the raw strip raw materials for unsealing. Thereby, when winding a packaging material raw material, it can prevent more effectively the state which one edge part in the width direction of at least one opening strip raw material floats. Thereby, it is possible to more effectively prevent the occurrence of wrinkles at one end portion in the width direction of each strip raw material for opening.

At least one of the two strip raw materials for unsealing can be adhered to the raw material of the main body sheet as a whole.

According to this configuration, at least one of the two strip raw materials for unsealing is adhered to the main body sheet raw material as a whole. Thereby, air can be prevented from entering between at least one of the strip body material for opening and the main body sheet material. Thereby, it is possible to prevent air from entering between at least one of the strip raw material for opening and the main body sheet raw material, which makes it difficult to wind the packaging material raw material.

As described above, according to the present invention, a packaging material that can be removed from an article with a smaller force, and a packaging material raw material for manufacturing the packaging material can be provided.
