Improving rewet shrink properties of casing |
摘要 |
Disclosed is a method of forming a seamless, non derivatized cellulose tubular film having enhanced rewet shrinkage properties. The enhanced properties are provided by first drying a hydrated extruded tube of non derivatized cellulose gel at one inflated diameter to form a tubular film. The film is then moisturized while holding an inflated diameter smaller than the drying diameter.
