Flexible Container with Peel Sleeve

The present invention relates to a flexible container (10). In an embodiment, the flexible container includes a first flexible film (12) superimposed on an opposing second flexible film (14). The first flexible film and the second flexible film are sealed along a common peripheral edge (16) to form an inner container having a closed chamber. The first flexible film and the second flexible film each has an outermost layer comprising an ethylene-based polymer. Each outermost layer is a surface-treated layer having a surface energy from 33 mN/m to 36 mN/m. The flexible container includes a peel sleeve (22, 24) superimposed on each respective outermost layer and along the common peripheral edge. The flexible container includes a release material (26) located between the peel sleeve and each outermost layer along the common peripheral edge. The release material releasably attaches the peel sleeve to the inner container.

Foam heating system

A foam assembly system is provided. The system is configured to heat a surface of foam. After the heating of the foam, an adhesive is applied, typically a high solids adhesive. The foam is then bonded to another foam surface. It has been found that the pre-heating of the foam before adhesive application greatly enhances the bond strength between the foam and the second foam surface to which it is adhered.
