- a spout obtained by injection molding random polypropylene was heat-sealed on the top of this bouch, and a flat bouch with a spout bout having a surface area of 90 cm 2 and an internal volume of 60 ml at the time of full injection was prepared.
- an acid coating film is formed on the inner surface of the biaxially stretched blow bottle made of PET single layer obtained in Example 8 by the following procedure. Shi It was.
- the biaxially stretched blow bottle made of PET single layer obtained in Example 8 was mounted in an inverted manner on a bottle holder provided in a metal cylindrical plasma processing chamber 1 having a diameter of 300 mm and a height of 300 mm.
- the bottle 8 is made of a sintered metal body having an outer diameter of 10 mm and a hole diameter of 120 m, which has an iron antenna 10 with a tip of 0.5 mm in diameter and a length of 30 mm added in a needle shape.
- a gas introduction pipe 9 was arranged.
- the vacuum pump 2 is operated to maintain the vacuum level outside the bottle in the processing chamber 1 at 2 KPa and the vacuum level inside the bottle at 2 Pa.
- Hexamethyldisiloxane gas 2 sccm and oxygen as the processing gas 20 sccm and argon lOsccm were introduced, and the degree of vacuum in the bottle was adjusted to 50 Pa.
