A method of stretch-blow-molding a beverage container for containing a carbonized beverage which method comprises providing a preform (11) having a neck part and a body part. The preform includes an inner layer (24) of a first polymeric composition, an outer layer (12) of a second polymeric composition, and an intermediate layer (22) 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.

1. A method of stretch-blow-moulding a beverage container for containing a carbonated beverage, the method comprising: (a) providing a preform having a neck part and a body part, the preform including an inner layer of a first polymeric composition, an outer layer of a second polymeric composition,
1. A method of stretch-blow-moulding a beverage container for containing a carbonated beverage, the method comprising: (a) providing a preform having a neck part and a body part, the preform including 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 having adhesive surface properties relative to the first and second polymeric compositions, the adhesive surface properties being permanently degradable by exposure to radiation of a certain wavelength; and(b) mounting the preform into a stretch-blow-moulding device and blow moulding the preform to form the beverage container by irradiating the body part with radiation including at least the certain wavelength which permanently degrades the adhesive surface properties of the third polymeric composition while shielding the neck part from the radiation. 2. The method of claim 1, wherein the first polymeric composition has a first absorption spectrum that includes the certain wavelength, and wherein irradiating the body part includes irradiating with radiation in the first absorption spectrum and with radiation having the certain wavelength. 3. The method of claim 1, wherein the first polymeric composition has a first absorption spectrum that does not include the certain wavelength, and wherein irradiating the body part includes irradiating with radiation in the first absorption spectrum and with radiation having the certain wavelength. 4. The method of claim 1, wherein the second polymeric composition has a second absorption spectrum that includes the certain wavelength, and wherein irradiating the body part includes irradiating with radiation in the second absorption spectrum and with radiation having the certain wavelength. 5. The method of claim 1, wherein the second polymeric composition has a second absorption spectrum that does not include the certain wavelength, and wherein irradiating the body part includes irradiating with radiation in the second absorption spectrum and with radiation having the certain wavelength. 6. The method of claim 2, wherein the radiation having the certain wavelength and the radiation in first absorption spectrum are emitted with different radiation intensities. 7. The method of claim 4, wherein the radiation having the certain wavelength and the radiation in the second absorption spectrum are emitted with different radiation intensities. 8. The method of claim 1, wherein the preform is selected from the group consisting of an injection-moulded perform and a pressure-moulded preform. 9. A method of stretch-blow-moulding a beverage container for containing a carbonated beverage, said method comprising (a) providing a preform having a neck part and a body part, the preform including an inner layer of a first polymeric composition and an outer layer of a second polymeric composition, wherein the first and second polymeric compositions exhibit adhesive surface properties relative to one another, the adhesive surface properties being permanently degradable by exposure to radiation of a certain wavelength; and(b) mounting the preform into a stretch-blow-moulding device and blow-moulding the preform to form the beverage container by irradiating the body part with radiation including at least the certain wavelength which permanently degrades the adhesive surface properties while shielding the neck part from the radiation. 10. The method of claim 9, wherein the first polymeric composition has a first absorption spectrum that includes the certain wavelength, and wherein irradiating the body part includes irradiating with radiation in the first absorption spectrum and with radiation having the certain wavelength. 11. The method of claim 9, wherein the first polymeric composition has a first absorption spectrum that does not include the certain wavelength, and wherein irradiating the body part includes irradiating with radiation in the first absorption spectrum and with radiation having the certain wavelength. 12. The method of claim 9, wherein the second polymeric composition has a second absorption spectrum that includes the certain wavelength, and wherein irradiating the body part includes irradiating with radiation in the second absorption spectrum and with radiation having the certain wavelength. 13. The method of claim 9, wherein the second polymeric composition has a second absorption spectrum that does not include the certain wavelength, and wherein irradiating the body part includes irradiating with radiation in the second absorption spectrum and with radiation having the certain wavelength. 14. The method of claim 10, wherein the radiation having the certain wavelength and the radiation in the first absorption spectrum are emitted with different radiation intensities. 15. The method of claim 12, wherein the radiation having the certain wavelength and the radiation in the second absorption spectrum are emitted with different radiation intensities. 16. The method of claim 9, wherein the preform is selected from the group consisting of an injection-moulded perform and a pressure-moulded perform.
