Embodiments of the disclosure relate to a blister package having a laminate structure that is heat-sealable to a lacquer layer on strain-hardened aluminum foil. The blister package includes a lid layer comprising a strain-hardened aluminum foil, a lacquer layer on a sealing surface of the strain-hardened aluminum foil and a laminate structure sealed directly to the lacquer layer. The laminate structure includes a multilayer film and a plurality of wells formed therethrough. The multilayer film includes a first formable layer of a thermoplastic material and a sealing layer of a copolyester material. The sealing layer overlies the first formable layer and has an outer surface opposite the first formable layer. The sealing layer has crystallinity from 5% to 20% as measured by differential scanning calorimetry (DSC). The outer surface of the sealing layer is sealed directly against the lacquer layer.

Formable films, laminate structures, and related methods

Formable films are provided that include one or more biaxially-oriented polyethylene terephthalate layers. The formable films include a metaphase with a metaphase transition of about 180&#xb0; C. to 200&#xb0; C. as measured by differential scanning calorimetry (DSC). The formable films further include a molded volume of greater than 200%. Laminate structures including the formable films and processes for producing and using the formable films and laminate structures are also provided.

A thermoplastic film is provided that includes a biaxially-oriented polyethylene terephthalate (PET) layer, a tensile strength in the longitudinal and transverse directions of about 2000 kg/cmor 3000 kg/cmor more, and a tear force in the longitudinal direction that is about 1.5 times as large as a tear force in the transverse direction. Such a film can include two or more layers. Processes for producing the thermoplastic film are also provided.
