MICROFRACTURED FILM AND METHOD FOR MAKING

A method for imparting hand-tearability to an organic polymeric film by impinging a multiplicity of ceramic microblades on a major surface of the organic polymeric film. The resulting microfractured organic polymeric film can be used as a hand-tearable tape backing for a hand-tearable adhesive tape....

Zusammenfassung:	A method for imparting hand-tearability to an organic polymeric film by impinging a multiplicity of ceramic microblades on a major surface of the organic polymeric film. The resulting microfractured organic polymeric film can be used as a hand-tearable tape backing for a hand-tearable adhesive tape. La présente invention concerne un procédé pour conférer une aptitude au déchirement à la main à un film polymère organique en frappant une multiplicité de microlames en céramique sur une surface principale du film polymère organique. Le film polymère organique microfracturé obtenu peut être utilisé comme support de bande déchirable à la main pour une bande adhésive déchirable à la main.
