Embodiment 1

[0069] (Manufacture of base film)

[0070] A total of 8 parts by mass of acetyl lemon was blended into a copolymer (100 parts by mass) having a monomer charge mass ratio (VD / VC) of 81 / 19 during polymerization of vinylidene chloride (VD) and vinyl chloride (VC). tributyl sebacate (ATBC), dibutyl sebacate (DBS) and epoxidized vegetable oil, further add a total of 1.4 parts by mass of epoxy-containing polymers, surfactants, stearic acid amide and silicon dioxide , and a polyvinylidene chloride-based resin was obtained. Next, the obtained polyvinylidene chloride-based resin was melt-extruded using an extruder screw having a diameter of 90 mm, and then biaxially stretched to obtain a base material film.

[0071] (Manufacture of films for opening sheets)

[0072] A total of 8 parts by mass of acetyl lemon was blended into a copolymer (100 parts by mass) having a monomer charge mass ratio (VD / VC) of 80 / 20 during polymerization of vinylidene chloride (VD) and vinyl chloride (VC). T...

Embodiment 2

[0078] In the production of the film for an opening sheet, the film a was further subjected to a tension heat treatment at 80° C. for 1 minute to obtain a film c for an opening sheet with a total thickness of 80 μm (two films with a thickness of 40 μm overlapped).

[0079] The base material film and the packaging body with an opening sheet were produced in the same manner as in Example 1.

Embodiment 3

[0081] In the production of the film for an opening sheet, the film a was further subjected to a tension heat treatment at 100° C. for 1 minute to obtain a film d for an opening sheet with a total thickness of 80 μm (two films with a thickness of 40 μm overlapped).

[0082] The base material film and the packaging body with an opening sheet were produced in the same manner as in Example 1.

Abstract

Provided is a package with an opening piece that is configured to enable more secure opening of the package. A package (1) with an opening piece includes: a package (2) that is formed from a first polymeric film, has a tubular body thereof filled with a content, and has both ends thereof closed; and an opening piece (3) that is formed from a second polymeric film and joined to the package in sucha manner that a part of a rim of the opening piece can be pinched, wherein a shrinkage rate of the second polymeric film at 120 DEG C is 15.0% or higher.

Description

technical field [0001] The present invention relates to a packaging body with an opening sheet, in particular to a packaging body with an opening sheet in which the packaging body is formed of a cylindrical film. Background technique [0002] Packages for sealing processed foods such as sausages are generally manufactured by filling a cylindrical film with contents, and then binding both ends together. In order to facilitate the opening of the packaging film of such a package, a cutting tape formed of a small film or an opening sheet called an opener is attached to the packaging film. Specifically, a part of the opening sheet is welded to the wrapping film, and when the peeling sheet is pinched and peeled off, the wrapping film is broken starting from the welded portion, thereby facilitating opening of the wrapping film of the package. [0003] In a conventional package with an opening sheet, when the opening sheet pinching the package is opened, the opening sheet may break...
