Package for an ophthalmic device having a multilayer lidstock containing a cyclic olefin seal layer

Abstract:

The present invention is related to a contact lens package with a heat sealable multilayer packaging lidstock formed from: a support layer and a peelable seal layer made from a polymer blend, such polymer blend formed from a material: from 40 to 85% by weight of one or more first amorphous cyclic olefin polymer(s) characterized by a glass transition temperature of at least 120.degree. C. from 10 to 55% by weight of one or more second amorphous cyclic olefin polymer(s) characterized by a glass transition temperature of less than 120.degree. C., and from 0.5 to 15% by weight, preferably 0.5 to 10% by weight of at least one elastomeric copolymer comprising at least one polymerized monovinylarene and at least one polymerized acyclic olefin.
