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