Abstract: A coextruded, multilayer, laminate, suitable for use as a top web in a VSP process, said multilayer laminate being characterized by a modulus at room temperature (23°C) of at least 4,000 kg/cm 2 and comprising at least

a polyolefin sealing layer a),
a gas-barrier layer b) and
a layer c) of a resin material having Tg comprised between 70 and 150 °C, preferably between 70 and 125 °C, and preferably between 70 and 100 °C, and a tensile modulus (evaluated according to ASTM D882 on a 250 µm sheet) of at least 1,900 MPa.

The new laminate is very formable and has good implosion resistance at the temperatures reached in the VSP process without stretching significantly in the longitudinal direction during the VSP process so that it can suitably be employed as a register printable VSP top web.

Abstract: A blister-type package includes one or more items (1) sandwiched between a backing (2) and a thermoplastic film (3) which is sealed to the backing along a closed line (4), external to the item(s) to be packaged. The thermoplastic film is mono- or bi-axially oriented when applied to the backing and, after application thereto, is heat shrunk so as to be tensioned over the item(s) and secures the item(s) to the backing. A method of making such a package also is disclosed.
