Title
(EN) ANTI -BLOCKING ADHESIVE - COATED SUBSTRATE, AND A METHOD FOR MAKING THE SAME
(FR) SUBSTRAT ADHÉSIF ANTI-ADHÉRENT ET SON PROCÉDÉ DE FABRICATION
Abstract
(EN) A substrate, such as, for example, a flap member of a pinch-bottom product bag, and a method of making the same, comprises a hot melt adhesive disposed upon the substrate so as to comprise first horizontally spaced upstanding portions whereby adhesive blocking is effectively eliminated or sig-nificantly reduced. A fiberized hot melt adhesive overcoat/ overspray may also be disposed atop the hot melt adhesive to further assure the elimination or reduction in the adhesive blocking. The fiberized hot melt adhesive may also be used in conjunction with a conventionally applied hot melt adhesive base or foundation upon the substrate or deposited directly onto the substrate.
(FR) La présente invention concerne un substrat, tel que, par exemple, un élément de rabat d'un sachet de produit inférieur à pince, et un procédé de fabrication de celui-ci, comprenant une colle thermofusible disposée sur le substrat de façon à comprendre des premières parties droites disposées à distance horizontalement permettant de supprimer efficacement ou de réduire significativement l'adhérence. Un revêtement adhésif thermofusible défibré/un excès de pulvérisation peut également être disposé au-dessus de la colle thermofusible pour assurer l'élimination ou la réduction de l'adhérence. La colle thermofusible défibrée peut également être utilisée en association avec une base de colle thermofusible appliquée de manière conventionnelle sur le substrat ou déposée directement sur le substrat.
