FOOD WRAP PAPER AND METHOD OF MANUFACTURING SAME

摘要

A method and apparatus for manufacturing food wrap paper. A paper web is formed and its first side is subjected to on-line surface treating by applying barrier material such that a water vapour and grease resistant barrier coating is formed onto the paper web. The forming and on-line surface treating are made so that after the on-line surface treating, the paper web has basis weight of 25.5 g/m2 to 34 g/m2 when measured in balance moisture.

1. A method for manufacturing food wrap paper, comprising:
forming a paper web; and on-line surface treating a first side of the paper web by applying barrier material so as to inhibit penetration of water vapour, water, grease and oily substances to the paper web; wherein the forming and on-line surface treating are made so that after the on-line surface treating, the paper web has basis weight of 25.5 g/m2 to 34 g/m2 when measured in balance moisture, and wherein the on-line surface treating of the first side of the paper web is performed in two or more on-line surface treatment phases comprising a first on-line surface treatment phase of barrier material and a second on-line surface treatment phase of barrier material following the first on-line surface treatment phase.
