Abstract
Official abstract text for this publication.
A formulation includes a polymeric material and can be used to form an insulated container.
First claim
Opening claim text (preview).
The invention claimed is: 1. An insulative container of cellular polymeric material comprising an extruded sheet having an inside extrusion tube surface, an outside extrusion tube surface and an elongated shape die-cut in a cross direction and formed into a tubular container wall with the outside extrusion surface facing the inside of the tubular container wall, the cellular polymeric material comprising a primary polypropylene resin, wherein beta-phase crystallinity is identifiable by wide angle X-ray diffraction and is not identifiable by differential scanning calorimetry. 2. The insulative cellular polymeric material of claim 1 , further comprising a polypropylene secondary resin. 3. The insulative cellular polymeric material of claim 1 , further comprising a slip agent. 4. The insulative cellular polymeric material of claim 1 , further comprising at least one nucleating agent. 5. The insulative cellular polymeric material of claim 1 , wherein a beta-phase crystallinity peak is present in the diffraction pattern from diffraction of crystal reflections from a β(300)plane. 6. An insulative container of cellular polymeric material comprising an extruded sheet having an inside extrusion tube surface, an outside extrusion tube surface and an elongated die-cut shape formed into a tubular container wall with the outside extrusion surface facing the inside of the tubular container wall, the cellular polymeric material comprising a primary polypropylene resin, wherein beta-phase crystallinity is identifiable by wide angle X-ray diffraction and is not identifiable by differential scanning calorimetry. 7. An insulative container of cellular polymeric material comprising an extruded sheet having an inside extrusion tube surface, an outside extrusion tube surface and wherein the extruded sheet is formed into a tubular container wall with the outside extrusion surface facing the inside of the tubular container wall, the cellular polymeric material comprising a primary polypropylene resin, wherein beta-phase crystallinity is identifiable by wide angle X-ray diffraction and is not identifiable by differential scanning calorimetry.
