A container having enhanced wall integrity is provided that includes a sidewall having a polygonal cross-sectional shape and an alignment structure formed therein. The alignment structure is adapted for orienting the container with respect to a second container such that the panel sections of the containers become parallel with one another, and the containers may be fully nested one within the other. The alignment structure may include a generally parabolic-shape protrusion that extends radially outwardly relative from the sidewall to form peaks along an external surface of the container and valleys along an inner surface of the container. The peaks are adapted to direct corners of the first container's sidewall toward the corners of the second container's sidewall in order to orient the containers as they are stacked.

A blown film of soil biodegradable aliphatic polyesters produced primarily from diacid and diol monomers. The diacid monomers may be of any type including succinic acid, adipic acid, and hexanedioic acid. The diol monomer may be of any type including ethylene glycol, propanediol, butanediol, and hexanediol. Commercial aliphatic polyesters produced from diacid and diol monomers include polybutylene succinate (PBS), polybutylene adipate succinate (PBAS), and polybutylene adipate (PBA). Comonomers may also be added. Such comonomers include chemicals with a single carboxylic acid, hydroxy, or amine moiety, which act as chain terminators, chemicals with three or more carboxylic acid, epoxy, and/or hydroxy moieties which, act as branching agents.

Various recyclable containers are described herein and generally comprise a frame made of a first paper-based material having a bottom wall and side walls that extend from the bottom wall; and a metallic layer that is removably positioned along an inner surface of the bottom and side walls of the frame; and at least one tab that is attached to a portion of the metallic layer. The at least one tab has a portion that extends past at least one sidewall of the container so that, during recycling, the at least one tab is pulled to remove the metallic layer from the frame. Examples of methods for manufacturing and recycling these containers are also described herein.

A plate comprises a planar central region with a perimeter and a lip with first and second sections, each including two ends. A first end of the first section extends from the perimeter up and away from the planar central region, and a first of the second section extends from a second of the two ends of the first section down and away from the planar central region. A plate comprises circular, mid and end regions. The mid-region protrudes from an outer edge of the circular region in a first direction away therefrom. The end-region protrudes from an outer edge of the mid-region in an opposite direction and away therefrom. The mid and end-regions include openings. A plate comprises a first area and a rim surrounding the first area. The rim has walls which intersect. Each of the walls is either straight or concave. Both of the walls includes openings.

A disposable bowl press-formed from a generally planar paperboard blank. The bowl has a large capacity, wide flange for easy handling and exhibits excellent rim stiffness. The bowl can include a bottom panel, a sidewall extending upwardly and outwardly from the bottom panel and a flange extending outwardly from the sidewall. The flange includes a rim portion having an arched central crown with a convex upper surface defining a radius of curvature RC of 0.650 to 1.180; and annular transition from the rim portion defining a radius of curvature, R3, and an evert extending downwardly from the annular transition, R3, wherein the bowl has an outermost diameter D of about 8 to about 10 and a height to diameter ratio, H/D, of from 0.18 to 0.20.
