- Resin Composition and Container Packaging Film, Container Packaging Bag and Container Package Using the Resin Composition
- the present invention relates to a resin composition and to a container packaging film and the like used in a container packaging bag for housing a container filled with a food or a medicament. More specifically, the present invention relates to a container packaging film ensuring excellent appearance and excellent antiblocking property between a container and a container packaging bag after high-pressure steam sterilization, and also a sealant film, a laminate, a container packaging bag and a container package using the container packaging film.
- packaging of housing a container filled with a food, a medicament or the like in a container packaging bag has been performed.
- the purpose of packaging varies depending on use and the container packaging bag is being used for various purposes, for example, for the purpose of mainly protecting the contents from deterioration, such as prevention of scratches on the container surface, prevention of mechanical damage of the container itself and prevention of permeation of oxygen or ultraviolet light , and for the purpose of describing the contents in the container, such as clarification of contents or handling standard by printing or the like.
- the problem often encountered in packaging a container in a container packaging bag is that the container and the container packaging bag undergo blocking during storage of the packaged container in a storehouse or the like and the container cannot be easily taken out from the container packaging bag on use.
- the case of subjecting a container package obtained by packaging a container in a container packaging bag to high- pressure steam sterilization before use is recently increasing.
- the high-pressure steam sterilization temperature is sometimes more elevated to shorten the high-pressure steam sterilization time.
- the blocking is more liable to occur as the temperature increases and therefore, it is a great technical subject demanded for the container package to solve this problem of blocking.
- the high-pressure steam sterilization is performed by depressurizing the container package to reduce the volume between the medical container and the container packaging bag and to provide a state in which the container packaging bag and the medical container are in tight contact .
- blocking is readily generated.
- a method of physically roughening the surface of the heat-seal layer of film to reduce the contact area with the container as in the case of wrapping a polyolefin-base container with a film having a heat-seal layer composed of a polyolefin-base resin.
- this method include a method of imparting a roughness to the film by roughening treatment (e.g. Japanese Unexamined Patent Application, First Publication No. Hei 5-309124), a method of imparting a physical deformation to the film by crimping, embossing, or the like.
- Other method using a resin composition includes a method in which a polymer composition comprising polybutene-1 and polypropylene and/or poly-4- metylpentene-1 is used for inner surfaces of a container packaging bag(e.g., Japanese Unexamined Patent Application, First Publication No. Hei 5-31156). Furthermore, a method of adding an additive to the polyolefin constituting the heat-seal surface of film can be used.
- the additive used here includes an inorganic filler such as silica and talc, an organic antiblocking agent such as spherical crosslinked methyl methacrylate, a metallic soap-base lubricant such as calcium stearate, and a fatty acid amide-base lubricant often used as a slipping agent of film, such as erucic acid amide .
