Films and Packing

Products:

SELVOL™ and ULTILOC™ films offer a unique variety of attributes:

Water solubility
Biodegradability/compostability
Oxygen and other gas/odor barrier properties
Resistance to solvents, oils and greases
Inherently anti-static
Innocuous and environmentally friendly

SELVOL™ and ULTILOC™ films are most recognized as the films used to package unit-dose detergents (e.g., P&G´s Cascade in the U.S.; Unilever's Persil Capsules in Europe). In these applications, a consumer can conveniently drop a pre-measured dose, wrapped in PVOH film, into the washing machine. The film completely dissolves within minutes of the start of the wash cycle.

Sekisui Specialty Chemicals has an active development program focused on development of high-performance films, both from solution cast and extrusion blown processes. We are applying various techniques, including copolymer technology, novel plasticization, and additives/compounding, to provide the film performance needed in demanding new applications.

Sekisui Specialty Chemicals holds key patents in melt extrusion and pelletizing of PVOH: USP 5,137,969 and USP 5,051,222 – with equivalent coverage in Europe and key Asian countries. We continue to develop novel melt processing technology with a fully equipped laboratory.

Recipe for Success

Select the Right PVOH Grade to Get the Most Benefit from Your Final Product

Before choosing any of the SELVOL™ grades, please consider what type of film you need.

PVOH molecular weight and hydrolysis levels have a large influence on the final properties of the film. In general, higher molecular weight PVOH grades will result in emulsion polymers with higher viscosity, increased shear thinning, higher tensile strength and higher wet tack. Lower hydrolysis levels will create good stability, increased water sensitivity and improved freeze – thaw stability.

SELVOL™ for films include SELVOL™ 165, 103, 107, 310, 325, 350, 425, 513, 523, 540.
