  • Air cellular cushioning article of enhanced strength per unit weight of film, and process for making same
    Patent number: 9017799
    Abstract: The cellular cushioning article comprises a thermoformed film bonded to a second film, with the thermoformed film having thermoformed regions separated by a land area. The thermoformed film has a combination of (i) a layer containing a high melt point polymer and (ii) thermoformed regions exhibit a high average maximum birefringence. The high birefringence corresponds with high stress on the polymer chains. The combination results in cells of substantially increased burst strength. The cellular cushioning article can provide higher burst strength per mil of film thickness, or can be produced using less plastic than prior art cellular cushioning articles, while maintaining the same or comparable burst strength. Also disclosed is a process for making the cellular cushioning article.
