Embodiment 1

[0113] A laminate (multilayer sheet) consisting of the lower innermost layer (A) / next layer (B) / lower next layer (C) is molded by the coextrusion molding method.

[0114] In the present specification, the density is a value measured in accordance with JIS K6922, MFR is in accordance with JIS K7210, and melting point is in accordance with JIS K7122.

[0115] Innermost layer (A): Propylene-ethylene random copolymer [IDEMITSU PP F744NP (manufactured by Idemitsu Petrochemical Co., Ltd.), melting point 135° C., MFR (abbreviation for melt flow rate, the same below) 6.4 g / 10 minutes] Layer thickness 10μm

[0116] Next layer (B): 50% by mass of homopolypropylene [IDEMITSU PP E304GP (manufactured by Idemitsu Petrochemical Co., Ltd.), melting point 162° C., MFR: 3.0 g / 10 minutes], 50% by mass of low-density polyethylene [ Nobatec HE30 (manufactured by Nippon Polyethylene Co., Ltd.), melting point 108°C, MFR: 0.3g / 10min] resin composition, layer thickness 100μm

[0117] Lower layer (C): ...

Embodiment 2

[0126] In addition to using a laminate (multilayer sheet) composed of the innermost layer (A) / next layer (B) / next layer (C) formed by co-extrusion molding as follows, use and implementation The packaging body for sterilization of the present invention was obtained by the same method as Example 1.

[0127] Innermost layer (A): Propylene-ethylene random copolymer [IDEMITSU PP F744NP (manufactured by Idemitsu Petrochemical Co., Ltd.), melting point 135°C, MFR 6.4g / 10min] layer thickness 10 μm

[0128] Next layer (B): 70% by mass of homopolypropylene [IDEMITSU PP E304GP (manufactured by Idemitsu Petrochemical Co., Ltd.), melting point 162° C., MFR: 3.0 g / 10 minutes], 30% by mass of ethylene-acrylate- Maleic anhydride copolymer [Lexpara ET182 (manufactured by Nippon Polyethylene Co., Ltd.), density 937kg / m 3 , melting point 99°C, MFR: 8g / 10min] blend, layer thickness 30μm

[0129] Lower layer (C): Homopolypropylene [IDEMITSU PP E304GP (manufactured by Idemitsu Petrochemical C...

Abstract

A packaging body for sterilization selectable with an emphasis placed on the heat sealability thereof with a sheet for sterilization without limiting the selection of a thermoplastic resin forming the innermost layer of a multi-layer packaging body unit. In a sterilization treatment, the packaging body for sterilization can sufficiently cope with a high temperature treatment such as a steam treatment, and there are no possibilities of the adhesion and the stain of an adhesive agent thereonto in the high temperature treatment. The packaging body is formed by heat-sealing the multi-layer packaging body unit (2) formed of the thermoplastic resin to the sheet (3) for sterilization. The packaging body (1) for sterilization is characterized in that when the sheet (3) for sterilization is peeled off from the multi-layer packaging body unit (2) for unsealing, the layers of the multi-layer packaging body unit (2) including at least the innermost layer (25) are moved to the sheet (3) for sterilization and peeled off.

Description

technical field [0001] The present invention relates to a package for sterilization. Background technique [0002] In the past, when storing medical materials, medical equipment, food and other articles, the packaging body that inserts and arranges the above-mentioned articles in the shape of a container, film, sheet, etc. is used, and the packaging body that has both bacteria and other microorganisms impermeable and sterilizing gas permeable Between the sterilization sheets with high performance, the sterilization sheet is heat-sealed on the package for sterilization. Then, the package for sterilization is treated with a sterilization gas such as ethylene oxide, hydrogen peroxide, or steam. [0003] However, for the sake of heat-sealability, conventionally commonly used sterilization packages are packages in which an adhesive layer is provided on the sealing surface of a sterilization sheet. The adhesive needs to be applied topically. Furthermore, there are many restrict...
