  • Patent number: 5661201
    Abstract: The present invention relates to a thermoplastic film including at least one ethylene copolymer, which film is capable of being sealed by a high-frequency current. The film is characterized by its inclusion of a sufficient quantity of at least one N,N'-ethylenebisamide in order to obtain a high-frequency sealing time not exceeding 1 second. The films thus sealed are especially useful for packaging.
