Abstract
A biaxially oriented plastic container having, in section, three layers formed by concentrically injecting two types of plastic into a cavity to mold a bottomed parison and stretch-blow molding said parison to form a biaxially oriented container with excellent heat-resistance and gas barrier properties; said two types of plastic having between them an intermediate layer of plastic having selected lengths of glass fiber.
Claims2
In a biaxially oriented container having three layers in section obtained by concentrically injecting two kinds of plastics into a cavity to mold a bottomed parison and stretch-blow molding said parison to form said biaxially oriented container with excellent heat-resistance and gas barrier properties, an intermediate layer of said container being formed of plastic containing selected lengths of glass fiber;
- said glass fiber having a length of 1-4 mm and being present in a percentage of 0.5-3.0 percent by weight with respect to said plastic which forms said intermediate layer, said plastic material of said intermediate layer being selected from the group consisting of polyethylene terephthalate, saponified ethylene-vinylacetate copolymer, ethylene-vinylalcohol copolymer, and m-xylene-type polyamide.
