ABSTRACT:
A transparent high density polyethylene (HDPE) sheet is disclosed. The sheet has a thickness greater than or equal to 0.05 mm and a bulk haze less than 2%. The HDPE resin is converted into a sheet by thermal processing and the sheet is then uniaxially oriented at a temperature above the melting point of the HDPE resin. The transparent HDPE sheet of the invention can be used for windows and plastic containers.
