Peelable-seal compositions and sealant film layers

摘要

The present invention pertains to peelable seal compositions and peelable seal film structures. The novel compositions are made from at least one homogeneously branched ethylene plastomer, a minor amount of at least one amorphous or elastomeric polymer and a lesser amount of at least one substantially crystalline or crystalline polymer. The compositions and film structure are useful in applications requiring broad heat seal windows such as, for example, cereal liners and packaging.
