ても検討されている。 Containers made of synthetic resin are widely used as containers for various liquid cosmetics, beverages, etc., and have recently come to be used as substitute containers for glass bottles and metal cans. In particular, stretch blow-molded containers made of polyethylene terephthalate are used as containers for storing soy sauce, edible oil, etc. because they have excellent gas barrier properties, toughness, and softness. Containers with high gas barrier properties against oxygen gas are also being considered as containers for storing carbonated drinks, wine, fruit juices, etc.

ることが殆んど不可能である等の弊害が存する。 By the way, as a container that satisfies a high degree of gas barrier property against oxygen gas, the container wall of a ready-made polyethylene terephthalate stretch-blow molded container is coated with a synthetic resin having excellent oxygen gas barrier properties such as polyvinylidene chloride. A coating film formed by a spray coating method, a dipping coating method, etc. has been developed, but containers with this synthetic resin coating film of polyvinylidene chloride have an oxygen gas barrier property of about 2 to 4 times at most. Not only is the storage stability of the contained contents insufficient, but also the polyethylene terephthalate stretch blow molding process and the coating/drying synthetic resin coating film formation process are separate processes. Container manufacturing equipment has become large and expensive, and when used containers are incinerated, chlorine is generated from the polyvinylidene chloride coating.
Furthermore, during recycling, it is difficult to separate the polyvinylidene chloride coating from the polyethylene terephthalate stretch-blow-molded container, making recycling almost impossible.
