AR Metallizing use the brand name RotoFLEX® for our wet-strength paper line. In addition to different basis weights (grammages) there are other differences in our RotoFLEX® papers that usually are related to specific requirements of the end users. Usually the end users are breweries or wineries, but we also support a variety of different beverage producers (sparkling water brands, for example).
The term 'wet-strength' itself indicates that the base paper before metallizing has been manufactured with a chemical that improves the bonding strength of the wood fibers when they have become completely wet in water. The wet strength chemical has little effect on properties of the paper when it is dry, but when wet the paper is stronger and resists breaking, tearing, and damage from rubbing. The most common way to measure the wet strength of paper is to test the tensile strength on an Instron-type machine, measuring strips when dry and also after soaking in water for five minutes.
With high quality products and considerate service, we will work together with you to enhance your business and improve the efficiency. Please don't hesitate to contact us to get more details of wet strength paper.
