PURPOSE:To obtain a calked pipe capable of preventing air transmission, in a film material used in enhancing hermetical sealing property, by adding a curing catalyst corresponding to a filled calking material to a specific hydrocarbonaceous polymer. CONSTITUTION:As the material of a film formed to the inner peripheral surface of the base end opening of a container main body and/or the outer peripheral surface of a plunger, a composition, wherein a predetermined amount of a curing catalyst corresponding to a calking material to be filled is added to a hydrocarbonaceous polymer of which the main chain having at least one hydroxyl group at the terminal thereof is saturated or partially saturated, is used. By using this composition, a calked pipe capable of sufficiently preventing air transmission through the contact part of the base end opening of the container main body and the plunger is obtained. |
