Abstract (en)
[origin: WO9931176A1] The present invention discloses seals including container closure liners, gaskets and barrier membranes, comprising a polymer composition having an oxygen transmission coefficient at a temperature of 25 DEG C of less than about 300 cm<3>.mil/100 in<2>.day.atm. (1.2 cm<3>/cm.day.MPa), wherein the polymer composition comprises at least one substantially random interpolymer (or a blend comprising at least one substantially random interpolymer and at least one other polymer) and from 0 to 80 percent by weight (based on the total weight of the composition) of at least one filler. The present invention also discloses sealing systems which include container closures such as bottle caps comprising these seals. The interpolymers or blends used to produce the seals of the present invention (as well as the novel seals themselves) exhibit a unique balance of properties including low oxygen permeability, low Shore A hardness and excellent tensile strain recovery.
