This invention relates to moisture resistant frozen food packaging using highly-sized paperboard and press applied moisture resistant over-print varnishes. Such structures of this type, generally, employ a moisture-resistant coating which is placed between the food product and the paperboard in order to provide a barrier for the food from the board and also to prevent the paperboard from absorbing moisture. Also, edge-wick moisture absorption is minimized by the use of the highly-sized sheet.
Cette invention concerne les emballages d'aliments surgelés résistant à l'humidité en carton fortement encollé enduit d'un vernis résistant à l'humidité appliqué sous pression sur les caractères d'imprimerie. Ce genre de procédé utilise, en général, un enduit résistant à l'humidité, entre le produit alimentaire et le carton, afin de les séparer et d'éviter que le carton n'absorbe l'humidité. L'utilisation du carton encollé réduit aussi l'absorption de l'humidité par le bord.
