Abstract
A microwave popcorn package is provided. The preferred package includes a flexible bag construction reinforced with a sidewall construction. The package is such that the flexible bag construction and the sidewall construction are selectively expandable between a collapsed configuration and an expanded configuration. After the package is opened, the sidewall construction provides for a rigid sidewall to provide a stand up bowl for access to the popped popcorn.
