发明名称 Composite polyethylene barrier structure
摘要 The present invention relates to an improved composite barrier laminate for an improved container for citrus juices and other liquids. The container utilizes a paperboard barrier laminate for the containment of essential oils and the prevention of losses of vitamin C. The laminate makes use of an inner barrier layer of a heat-sealable oxygen and flavor oil barrier material to enhance the barrier properties of the laminate as well as an extremely thin low density polyethylene food contact layer to provide a resultant secure homogenous non-polar heat seal.
