  • Publication number: 20220062070
    Abstract: A forming structure includes an outer surface configured to receive a polymer web, an inner surface, a thickness between the outer surface and the inner surface, and a plurality of openings extending through the thickness at an acute angle relative to a plane tangential to the outer surface. Each of the plurality of openings has a shape at the outer surface defined by a first ellipse having a first major axis and a first minor axis and a second ellipse having a second major axis and a second minor axis. The first major axis is substantially parallel to a machine direction and coincides with the second minor axis. The second major axis is substantially parallel to a transverse direction orthogonal to the machine direction and is offset from the first minor axis.

  • Patent number: 5258422
    Abstract: The present invention relates to compostable and biodegradable thermoplastic compositions comprising a thermoplastic polymer, a hydrolytically unstable antioxidant, a pro-oxidant, an accelerator, and a property modifier. The hydrolytically unstable antioxidants effectively prevent the thermoplastic polymer from breakdown by oxidative or thermal degradation under dry conditions. Under wet conditions, the hydrolytically unstable antioxidant becomes ineffective and the thermoplastic polymers breakdown to low molecular weight materials.
