ABSTRACT:
A sheath-encapsulated primary and secondary container for food, beverage and consumable products employs a structure to protect the contents of the container against the stresses of processing, filling, warehousing, distribution, merchandising and customer use. The structure is formed of paper-based or polymeric or other material to be encapsulated so that it may be reused or recycled and need not be of food-grade or virgin type. A sheath encapsulates the structure and is of film material such as polymeric barrier material, providing sheath portions extending over the exterior of the structure and at least partially internally thereof, the internal sheath portion defining a vessel within the structure for receiving the contents. The sheath interposes a barrier between the structure and the contents, and also provides barrier between the structure and outside environment. Various container configurations, including multiple compartment, and reshipper types, are disclosed.
Methods of forming such encapsulated containers are disclosed.
