A new system of forming flexible rollstock produces packages that can replace cans, jars, and other rigid containers. Primapak, the newest addition to the earthclear line from clear lam packaging, uses stiff, thermoformed film with rigid tops and, in some cases, bottoms to make packaging that keeps its integrity while still remaining flexible. The resulting package can be stacked and otherwise treated like a rigid container. The primary ecological advantage for primapak is its light weight and low volume. The finished container has 10 percent or less of the weight of comparable rigid containers.
