PROCESS FOR MANUFACTURING OF A ROBUST, FLEXIBLE WAXED WEB MATERIAL |
摘要 |
A process for manufacturing robust, flexible sheet-like material, includes the steps of a) applying a waxy composition to the web to form a waxed web; b) leading the waxed web via at least one roller to a chiller; c) cooling the waxed web; and d) leading the waxed web to a collection station for collecting the waxed web for further processing. The waxy composition comprises about 10-60 wt-% of a waxy compound and about 90-40 wt-% of a diluent. The waxy compound is selected from the group consisting of A) monoesters of a polyhydric aliphatic alcohol and a fatty acid; B) diesters of a polyhydric aliphatic alcohol and a fatty acid; and C) mixtures of said monoesters and diesters. The coating forms a stable liquid mixture at a temperature between about 35° C. and about 100° C., has a liquefaction temperature of at least about 30° C., and has a contact angle with a flat surface of the substrate of less than about 35° when measured at a temperature of 60° C. |
