Abstract
Included are food packaging materials and processes that are useful for commercial products to extend the freshness and preserve the integrity and shelf-life of packaged foods. Said food packaging materials utilize a low bioburden, biodegradable and/or compostable shock absorbing/cushioning nonwoven structure and some form or forms of an antimicrobial and/or antifungal agent consisting of silver or silver-based species that destroy microbes which would otherwise spoil the food. The shelf-life extension process involves silver-based antimicrobial agents that function to mitigate the spread of food spoilage pathogens when they come in contact with the said food packaging materials. Fluid absorbing or superabsorbent, capabilities may be incorporated in the structure to control excess fluids.
