A process for forming a plastic article, such as a container, involves heating at least one or more layers individually to temperatures below the melting point, immediately stacking two or more layers while retaining the peripheral portion of the layers and immediately forming the stacked layers into a plastic article which is then allowed to cool. Alternatively after stacking the layers, the stacked layers are immediately forged into a preform in a heated and lubricated mold and immediately thermoformed into a plastic article, which is then allowed to cool. The layers may be diverse (i.e. material, shape, molecular weight, additives, etc.) or similar and stacked so as to provide a layered angular orientation. |
