Side portions (3) consisting of the above-mentioned valley folds between the portions (2)
(4) In a package for an article to be packaged such as a disposable diaper configured to seal the upper and lower openings (6) and (7), each valley of the double-sided valley forming the above-mentioned both side portions (3) and (4). The fold lines (5) and (5) are separated between the front portion (1) and the back portion (2), and substantially within the separation section (8) of the valley fold lines (5) and (5), the front portion (5). In 1), a linear perforation (9) for forming an opening for taking out a packaged object was provided.

[0009] A plurality of compressible packages such as disposable diapers are stacked vertically and / or laterally, and as a whole a group of square tubular piles is spread in the above-mentioned tubular plastic sheet in the same shape. Filling is performed, but the upper end of the packaged object is below the top (10) of the linear perforation (9).
The compressible package is formed by folding a disposable diaper or other disposable diapers, a menstrual pad, incontinence pants, a urine collecting pad, etc. into a rectangular thick plate.

FIG. 1 shows an example in which a substantially inverted U-shaped linear perforation (9) located entirely within the separation section (8), and FIG. 2 shows that most of the peaks are within the separation section (8). It is located, and the skirt end crosses the valley fold line (5) and slightly enters both sides (3) and (4) (allowable maximum penetration length: 40 mm). A substantially inverted V-shaped linear perforation (9) FIG. 3 shows an example in which (9) which is a substantially inverted V-shaped linear perforation is applied, and is the same as FIG. A linear perforation (9) for forming an opening for taking out an article to be packaged has a substantially inverted U-shaped or substantially inverted V-shaped steep mountain-shaped shape substantially located in the separated section (8). Therefore, the width in the horizontal direction of the opening for taking out the packaged object formed by cutting open the linear perforation (9) is larger than the width in the thickness direction of the packaged product, It is smaller than the width of the front.

[0011] The top portion (10) of the chevron-shaped linear perforation (9) is located in a space above the article to be packed and accommodated in the tubular plastic sheet, and the perforated chevron shape. The skirt extends to a position corresponding to the article to be packaged (8). The upper opening (6) of the tubular plastic sheet is connected to the package handle band (11) via a seal line in a state where both sides are folded in a valley in advance. The lower opening (7) of the cylindrical plastic sheet is sealed after filling the tubular plastic sheet with the article to be packaged.
