When it comes to package design, fresh produce films require a specific balance of properties to protect the food and preserve freshness for as long as possible. Fruits, vegetables, and leaves are living tissues which continue to respire after harvesting.
To maintain optimal freshness in these applications, oxygen, carbon dioxide and moisture must be able to permeate through the packaging film at specific rates. Film clarity is another important factor as consumers value visual appeal and aesthetics when purchasing fresh foods. Finally, produce packaging needs sufficient durability for high-speed converting and to ensure the produce is protected during storage and transportation.
