AI Technical Summary
Technical Problem
Existing plastic packaging materials face challenges in achieving dimensional stability and recyclability, particularly in flexible containers, which often result in deformation and non-uniform stress patterns that complicate recycling processes.
Method used
A multi-layered plastic sheet structure is developed, comprising layers with specific molecular orientations and stress patterns that counterbalance each other, maintaining flatness and reducing deformation, while being recyclable through existing HDPE recycling streams.
Benefits of technology
The multi-layered structure maintains dimensional stability and flexibility, allowing for efficient recycling without additional processing steps, aligning with existing HDPE recycling infrastructure.

Abstract
The present description describes a sheet comprising: a multi-layered structure comprising: a plurality of layers including an outermost layer and an innermost layer, each of the plurality of layers having a molecular orientation that results in a strain value for each layer; wherein the strain values of at least two of the plurality of layers are not zero and are different from each other; and wherein the multi-layered structure has a net strain value that is less than the largest strain value of the plurality of layers.
