NOVEL FLAVOUR/AROMA BARRIER LAMINATES FOR PAPERBOARD CARTONS |
摘要 |
<p>The present invention relates to an improved container for citrus juices and other liquids. The container utilizes a paperboard barrier laminate for the containment of essential oils and flavours. The laminate makes use of a layer of a heat-sealable polycarbonate polymer food contact layer to enhance the barrier properties of the laminate. Specifically the invention provides a container for liquids containing essential oils and/or flavours, said container constructed from a laminate characterized by comprising: a) a paperboard substrate (36); b) an outer layer of a heat-sealable low density polyethylene polymer (34) coated on said outer surface of said paperboard substrate; c) an inner layer (38) of a low density polyethylene polymer coated on said inner surface of said paperboard substrate; and d) a liquid contact layer comprised of 1) a tie layer (40) or 2) an extrusion coatable adhesive and a heat-sealable polycarbonate polymer layer (42) which can be heat-sealed with the outside layer of low density polyethylene of the laminate on conventional equipment at temperatures ranging from 250 DEG F - 500 DEG F. Also disclosed is a process of making the laminate.</p> |
