Title
(EN) VAPOR DISPERSIBLE PLASTIC FILM PAINT ADHERENCE AND CLING
(FR) FILM PLASTIQUE DISPERSANT LA VAPEUR, ADHERANT A LA PEINTURE ET A AUTO-ADHERENCE
Abstract
(EN)
A co-extruded plastic film comprises an outer layer (12) formed of a polymer or co-polymer having a high surface energy, such as corona treated high density polyethylene; a core layer (14) preferably formed of a polyolefin, which can included a foamed polymer preferably formed by an exothermic blowing agent; and an inner layer (16) that includes a filler of sufficiently large particle size and in an sufficiently large amount that water vapor can escape laterally from under the film. The inner layer can also include a desiccant and be embossed. This film allows vapors to disperse and can also be moisture absorbent and vapor permeable. The film also has the benefit that one surface has high paint adherence and the opposite surface clings to a substrate, typically a painted metal or simple metal surface.
(FR)
Un film en plastique co-extrudé comprend une couche extérieure formée d'un polymère ou d'un copolymère possédant une énergie de surface élevée, tel qu'un polyéthylène haute densité traité par décharge corona ; une couche centrale formée de préférence d'une polyoléfine, pouvant comporter un polymère en mousse produit par un agent gonflant endothermique ; et une couche intérieure contenant une charge de particules suffisamment grande et en quantité suffisante pour que l'eau s'échappe latéralement par le dessous du film. La couche intérieure peut également comprendre un déshydratant et peut être estampée. Ce film permet à la vapeur de se disperser et peut également absorber l'humidité et être perméable à la vapeur. Ce film a également l'avantage de présenter une surface possédant une grande adhérence à la peinture et une surface opposée auto-adhérente sur un substrat, généralement une surface métallique peinte ou une surface métallique simple.
