Abstract
A method of stretch-blow-molding a beverage container for containing a carbonized beverage which method comprises providing a preform () having a neck part and a body part. The preform includes an inner layer () of a first polymeric composition, an outer layer () of a second polymeric composition, and an intermediate layer () of a third polymeric composition. The third polymeric composition has adhesive surface properties relative to the first and second polymeric compositions, and the adhesive surface properties are permanently degraded by exposure to irradiation of a certain wavelength or certain wavelengths and intensity. The method further comprises mounting the preform onto a stretch-blow-molding device and blow molding the preform into the beverage container by irradiating the body part with radiation at least including the certain wavelength or certain wavelengths and intensity while protecting the neck part from any substantial radiation.
