Abstract
A laminate providing an effective barrier to the migration of essential oils and/or flavorings, such as d-limonene and for the retention of Vitamin C, is provided comprising from the outer surface to the inner surface, a paperboard substrate, a web of nylon directly coated thereon, a web of Surlyn overlying and in contact with said nylon web and a web of olefin overlying and in contact with said Surlyn web. Preferably the paperboard substrate is also coated on the external surface thereof with a web of heat sealable polymer. Containers constructed from such laminates are especially useful as fruit juice containers which enable significant flavor and Vitamin C retention in the liquid i.e., fruit juice contained therein over the normal shelf life of the product.
