Patent

CA 2339963

The present invention is directed to biaxially oriented polymeric films. Specifically, the present invention is directed to biaxially oriented polyethylene films having unidirectional tear characteristics in machine direction and method thereof. The film of the present invention comprises (1) a core layer of medium density polyethylene (MDPE) and optionally a cavitating agent; and (2) at least one skin layer on at least one surface of the core layer. The skin layer is also made from a polyethylene. The core and skin layers coextensively adhere to one another and are biaxially oriented in both machine and traverse directions.

La présente invention concerne des films polymères à orientation biaxiale. Plus précisément, cette invention s'applique à des films de polyéthylène à orientation biaxiale avec caractéristiques de déchirement unidirectionnel dans le sens machine et dans le sens transversal. Le film selon la présente invention comprend (1) une couche centrale composé d'un polyéthylène de densité moyenne et un agent de cavitant; et (2) au moins une couche de revêtement sur au moins l'une des surfaces de la couche centrale. La couche de revêtement est elle aussi réalisée en polyéthylène. Les couches centrale et de revêtement adhèrent l'une à l'autre et sont orientées biaxialement dans le sens machine et dans le sens transversal.
