The present disclosure relates generally to tension-activated, expanding articles, films, and sheets including a multi-slit pattern. In some embodiments, these articles, films, and/or sheets are used as cushioning films and/or packaging materials. The present disclosure also relates to methods of making and using these tension-activated, expanding articles, films, and sheets.

Multi-slit tension-activated, expanding sheets

Face mask

Compositions are provided including an uncrosslinked thermoplastic nitrogen-containing matrix material and composite particles distributed in the matrix material. The composite particles each include a chemical blowing agent particle encapsulated within a shell including an uncrosslinked thermoplastic material. The uncrosslinked thermoplastic material exhibits at least a certain minimum complex viscosity at a decomposition temperature of the chemical blowing agent particle. Also described are foam compositions and articles including the foam compositions, such as a sheet or multilayer construction. Composite particles are further provided. Methods of making the foam compositions are additionally described herein. Also, polishing pads, polishing systems, and methods of polishing a substrate are provided.
