Abstract: The invention relates to a thermoplastic elastomer composition comprising a mixture of a. 5-50 wt. % of a block copolymer type thermoplastic polyurethane elastomer (TPE-U) b. 5-50 of a block copolymer type thermoplastic co-polyester elastomer (TPE-C), and c. 10-60 wt. % of a thermoplastic styrenic block copolymer (TPE-S), wherein the wt. % is based on the total content of the elastomer composition. The elastomer composition might be efficiently connected with polar polymers so that corresponding polymer articles are formed.

Abstract: A closure made of metal or plastic for a container for accommodating beverages or food has a mouth opening which is to be closed by the container closure. The container closure has a sealing insert which is arranged such that it closes the mouth opening with sealing action when the container closure is fitted on the container. The container closure, including the sealing insert, does not contain any halogen-containing material, and the sealing insert comprises at least two different polymers, of which at least one is a barrier polymer with a Shore D hardness of at most 40 and oxygen permeability of at most 1000 cm3·100 ?m/m2·d·bar and, without the Shore D hardness being limited, with oxygen permeability of at most 10 cm3·100 ?m/m2·d·bar.

Abstract: The present invention relates to compositions (compounds) which can be used as seal material in vessel caps, even under pasteurization conditions and possibly sterilization conditions. More specifically, the invention relates to such compositions that are suitable for vessel caps that can be unscrewed, such as lug screw caps and in particular Press-on/Twist-Off® caps, and that result in a reduced migration of undesirable substances.

Abstract: The invention relates to a polymer compound for a PVC-free sealing system for container closures, which is equipped with at least one oxygen-consuming compound, in which the Shore D hardness of the polymer compound is at least 20 and the polymer compound has a melt flow index (190° C., 5 kg) of at least 5.

Abstract: The invention relates to a method for producing a vessel closure for vessels comprising an opening that is to be closed by the vessel closure, an inner diameter of more than two cm and surrounds a polymer-based sealing element that is arranged in the vessel closure in such a manner that is sealingly rests on the opening of the vessel in the closed state. A polymer material becomes sufficiently free-flowing by warming and is applied to the vessel closure in the region of the sealing element that is to be produced, and optionally, is mechanically formed into the desired shape which it maintains after cooling. The invention also relates to a metal or plastic vessel closures for vessels for receiving drinks or food, and comprises a sealing insert, the material thereof being selected so that the migration of material components into the drink or food, that are a health risk, is prevented.

Abstract: The invention relates to a polymer compound for a sealing insert for a container closure, in particular for fat-containing filling materials, which has a composition such that the migration of constituents of the compound into the filling material is reduced, characterized in that the Shore A hardness of the polymer compound is between 45 and 95 and in the compressive deformation test analogous to ASTM D395-97 Method B at 70 DEG C the polymer compound exhibits a compression set of 30-90%.
