る。BACKGROUND OF THE INVENTION Polyethylene is a preferred material used to make containers. It is inexpensively manufactured by injection molding or extrusion. However, polyethylene has a serious drawback: when a fluid such as a substance containing hydrocarbon as a main component is packed in a polyethylene container, it tends to exude from the wall of the container. This is because polyethylene has permeability.

を防止するものである。The aluminum stearate is used as a drug having the ability to gel or thicken aliphatic and aromatic hydrocarbons. Its presence as a thermoplastic resin or additive to the thermoplastic lining in the present invention reduces permeation through the vessel wall. When an aliphatic or aromatic hydrocarbon penetrates inside the container wall or inside the lining, it is partially thickened by the presence of aluminum stearate, thereby preventing penetration.

に適用される。Prior to mixing, the mixtures were covered (the container was capped). After mixing, the additive is in a state suitable for subsequent mixing with the resin (hereinafter referred to as secondary mixing). The secondary mixing then produces a thermoplastic composite that reduces and prevents wall penetration. After the secondary mixing with the thermoplastic resin, the additive is preferably contained in 3 to 6% of the total composition of the secondary composite obtained by the secondary mixing. The mixture can also be used as a thermoplastic lining for containers made of other materials. Such a lining is applied to the container by means known to those skilled in the art.
