Title (EN) ADHESIVE COMPOSITION
(FR) COMPOSITION ADHESIVE
Abstract: front page image
(EN)This adhesive composition for use in plastic and metal foil composite packaging materials contains (A) polyester glycol having a molecular weight of 3,000 to 1000,000, polyester polyurethane polyol having a molecular weight of 3,000 to 100,000, or a mixture thereof; (B) a silane coupling agent; and (C) organic polyisocyanate, wherein the equivalent weight ratio (NCO/H) of the isocyanate group (NCO) to active hydrogen (H) is from 1 to 10. A packaging material making use of the present composition prevents the plastic film from peeling off the metal foil even when the sealed packaging filled with a food is treated in boiling water for sterilization. Such packaging exhibits excellent resistance to foods and permits their stable and long-term preservation.
(FR)La composition adhesive utilisable pour des materiaux d"emballage en feuilles composite de plastique et de metal contient (A) un polyester glycol ayant un poids moleculaire de 3.000 a 100.000, un polyester polyurethane polyol ayant un poids moleculaire de 3.000 a 100.000, ou un melange des deux; (B) un agent silane de copulation; et (C) un polyisocyanate organique, ou le rapport equivalent en poids (NCO/H) du groupe isocyanate (NCO) avec l"hydrogene actif (H) est de 1 a 10. Un materiau d"emballage utilisant la presente composition evite que la pellicule de plastique ne s"ecaille de la feuille metallique meme quand l"emballage ferme est rempli de produits alimentaires et qu"il est traite dans l"eau bouillante pour sa sterilisation. Un tel emballage permet une longue et stable conservation des produits alimentaires.
