PE film is commonly used in a very broad range of packaging applications and the need for efficient anti-fogs is essential for the quality and appearance of fresh packaged food. Fogging appears when packaged food is placed in refrigerated storage. This is the case of packaged meat, oven backed products, salads, vegetables and fruits. The entrapped air cools and moisture will condense and appear as small discrete droplets on the packaging. Fogging is unacceptable for a number of reasons as it reduces the visibility of the product, provides a less attractive appearance of the package, and the presence of water droplets may cause deterioration of product quality. The request for good and reliable anti-fog solutions is on a steady growth path in a food packaging market where the consumer choice is moving more and more towards ready meals and pre-prepared food that offers convenience in a busy daily schedule.
