Polyvinyl alcohol has excellent film forming, emulsifying and adhesives properties. It is also resistant to oil, grease and solvents. It has high tensile strength and flexibility, as well as high oxygen and aroma barrier properties. However these properties are dependent on humidity, in other words, with higher humidity more water is absorbed. The water, which acts as a plasticiser, will then reduce its tensile strength, but increase its elongation and tear strength.

PVA HWF-17 is usually used as a surface treatment agent for paper and paperboard. When higher coverage isrequired, HWF-05 or HWF-08 may be applied. A sizing solution of 2-5% is used, with a plasticizer for example glycerol, an insolubilizer for example glyoxal and defoamer added to the solution. A wax emulsion (10-50% of the weight of PVA ) may be added to prevent sticking to the dryer and staining on the calendar roll. Metallic stearates and rosins may also be applied.The applications of PVA for paper industry are listed as follows.
