Laminated packaging material with good oxygen and aroma barrier properties and manner of manufacturing the material.

摘要

Laminated packaging material for packaging of juice and other oxidisation-sensitive liquids containing polar aromatic substances. The material exhibits as an aroma barrier a layer (2) of an acid-modified polyethylene terephthalate which has on the one hand low absorption of the said aromatic substances and on the other hand sufficiently low oxygen permeability to give the packaged juice or liquid satisfactory chemical product protection in cold storage. <IMAGE>
