Problems solved by technology

However, the package sheet formed from a resin film, such as polyethylene film and so forth may generate husky (or crinkly) noise upon handling due to friction with a packaging film upon opening the package and taking out the absorbent article.
On the other hand, the resin films are firmly bonded by heat seal to cause difficulty in opening the package for large anti-peeling resistance upon peeling the heat sealed portion.
Furthermore, since the large force is required in opening the package, high husky or crinkly noise can be generated.
As a result, uncomfortable feeling may be caused for the fear if unpacking of the sanitary napkin or the like can be perceived by surrounding people.
On the other hand, the package sheet formed from polyethylene film is not always preferably in terms of product form due to stiff external appearance of the individual package.
Furthermore, since the polyethylene film is heat sealed, gas-tightness of the sealed individual package becomes excessively high to cause bursting of the package sheet at the heat sealed portion when large external force is applied during carrying.
In case of individual package of the absorbent article employing the package sheet of non-woven fabric, husky noise to be generated by such package sheet upon unpacking is small.

(2) Example 1

[0115] The package sheet 10 having a three-layer structure consisted of the spun-bonded non-woven fabric on the side of the first surface 11, the spun-bonded non-woven fabric on the side of the second surface 12, and a meltblown non-woven fabric sandwiched between the spun-bonded non-woven fabrics, having a basis weight of 18 g / m.sup.2, and being formed with a stripe form smoothed region 33a on the first surface 11, to which the tape 30 is bonded, as shown in FIG. 4, was used. The smoothing process was performed using a roll having a projected portion of a stripe pattern with smooth top surface, and a roll having smooth surface in entire periphery. Both rolls were heated to 115.degree. C. The packager sheet 10 is pressurized by both rolls at a pressure of 36.3 kPa.

The smoothing process was performed using a roll having a projected portion of a stripe pattern with smooth top surface, and a roll having smooth surface in entire periphery. Both rolls were heated to 105.degree. C. The packager sheet 10 is pressurized by both rolls at a pressure of 36.3 kPa.

The smoothing process was performed using a roll having a projected portion of a stripe pattern with smooth top surface, and a roll having smooth surface in entire periphery. Both rolls were heated to 105.degree. C. The packager sheet 10 is pressurized by both rolls at a pressure of 36.3 kPa.

Abstract

An individual package of an absorbent article permits a base end of a tape to be bonded with sufficiently large bonding strength without complicating packaging process and increasing manufacturing cost. The absorbent article is wrapped by a package sheet having side edge portions and end edges, and one end edge is overlapped over the other end edge. The package sheet is sealed along the side edge portions, a base end of a tape is fixed on the surface of the package sheet located outside in an overlapping portion, and a free end of the tape extends across one end edge and is releasably adhered on the outer surface of the package sheet adjacent one end edge. The package sheet has a surface, on which the base end of the tape is fixed, the surface being smoothed by a smoothing process.

Description

[0001] 1. Field of the Invention[0002] The present invention relates to an individual package, in which an absorbent article, such as sanitary napkin, panty liner, sanitary tampon, incontinence pad, disposable diaper and so forth is individually packed.[0003] 2. Description of the Related Art[0004] For example, an absorbent article, such as sanitary napkin or the like, is individually packed into an individual package. Conventionally, a package sheet of the individual package is formed from a polyethylene film or the like. It is a typical structure that side portions of the package sheet are heat sealed in a condition wrapping the absorbent article.[0005] However, the package sheet formed from a resin film, such as polyethylene film and so forth may generate husky (or crinkly) noise upon handling due to friction with a packaging film upon opening the package and taking out the absorbent article. This is true even in the case where the individual package is taken out from a porch, is...
