Abstract
A method for forming an overwrap container includes the steps of a) providing a base container having a first side seam on a side wall that extends along a longitudinal axis to define an internal volume, and a bottom secured to the side wall; b) providing the side wall of the base container with connecting elements on an outer periphery of the side wall; c) providing an overwrap having a second side seam over the side wall of the base container such that the overwrap is joined in spaced apart relationship by the connecting elements to the side wall of the base container; d) clamping the overwrap to the base container along the second side seam to form a first compressed area; e) clamping the overwrap to the base container in an area 180° removed from the second side seam to form a second compressed area: and f) reforming the second compressed area to define an overwrap container having a substantially uniform spacing and air gap between the base container and the overwrap except in the first compressed area.
