Patent

CA 2186009

The invention concerns a foil for covering goods carriers such that they can be handled more securely, so replacing the known aluminium cover foils. The foil comprises a plastics matrix which contains a particulate filler, the filler being selected and present in the matrix in such a quantity that the resistance to piercing of the foil is reduced to a limit of less than 450 N/mm (measured on an approximately 150 µm thick foil). A highly crystalline polypropylene is used as the plastics matrix material.

L'invention concerne un film recouvrant des plaquettes-supports de produits pour en permettre une manipulation plus sûre, remplaçant ainsi les films de recouvrement en aluminium connus. Ce film comporte une matrice plastique qui renferme une charge particulaire, cette charge étant choisie et présente dans la matrice en une quantité telle que la résistance à la perforation du film est réduite à une valeur limite inférieure à 450 N/mm (mesurée sur un film d'environ 150 µm d'épaisseur). La matrice en plastique est constituée d'un polypropylène fortement cristallin.
