发明名称 Gaskets made from olefin polymers
摘要 Gaskets comprising either at least one homogeneously branched ethylene polymer or at least one elastic substantially linear ethylene polymer, at least one ethylene/carboxylic acid interpolymer; and at least one slip agent are disclosed. These gaskets may also contain enhanced polyethylenes produced by the direct polymerization of various combinations of novel elastic substantially linear olefin polymers in multiple reactors using either single or multiple catalysts. These gaskets may also be comprised of at least one ethylene polymer and at least one ionomer. The above mentioned gaskets may also contain slip agents and/or foaming agents. The gaskets are particularly useful for sealing food and liquid containers and do not contribute to taste and/or odor of the packaged product, which is especially useful in food-stuff applications. Gaskets comprising substantially linear ethylene polymers have processability similar to highly branched low density polyethylene (LDPE), but the strength and toughness of linear low density polyethylene (LLDPE).
