SNP has been a supplier of water-soluble and water-based products to the paper industry since it was founded in 1964. Our sodium alginate, polyvinyl alcohol, polyurethane dispersions (PUDs), polyester-based emulsions, acrylic/SB emulsions, and ethylene acrylic acid (EAA) are used in a wide variety of paper grades. More details are available below.

SNP’s aqueous polyvinyl alcohol products for ideal for customers who:
SNP’s sodium alginate is used in silicone release liner. It seals the surface of the base paper, allowing the surface to hold out the silicone coating and the desired performance is achieved at lower silicone coat weights. The sodium alginate does not affect the performance of the silicone coating. The starch/sodium alginate sizing is applied to the paper with puddle or meter sized press.
SNP’s aqueous polyvinyl alcohol products for ideal for customers who:
SNP’s sodium alginate is used in high Gurley porosity grades like card stock and poster papers. It works in synergy with starch to efficiently close the surface of the sheet. The starch/sodium alginate sizing is applied to the paper with puddle or meter sized press.
SNP’s aqueous polyvinyl alcohol products for ideal for customers who:
Sodium alginate improves the runnability and water retention of pigmented paper coatings. By controlling water loss to the sheet during application and metering, binder migration and print mottle can be prevented. Alginate improves the flow properties of a coating during application and metering. SNP will help you determine the best sodium alginate to meet your target coat weights, improve leveling, eliminate coating defects, and reduce process variability and maintenance.
Polyvinyl alcohol is used as a binder and/or optical brightener carrier in pigmented paper coatings. It provides unique rheological properties that give uniform surface with metered rod or blade applicators. Polyvinyl alcohol can be used as a replacement for protein in pigmented paperboard coatings.
Polyurethane dispersions (PUDs) are used in printing grades to increase durability and printing strength.
SNP’s aqueous polyvinyl alcohol products for ideal for customers who:
Sodium alginate is used in ink jet printing papers to absorb water carrier from ink to help with ink setting.
Polyvinyl alcohol is a very strong binder. It is used in ink jet formulations applied at the size press to bind the structured silica pigments which are highly absorptive and require substantial binder strength.
SNP’s aqueous polyvinyl alcohol products for ideal for customers who:
Sodium alginate is an excellent film former with oil and grease resistance. It is often used with other film formers such as starch and polyvinyl alcohols to improve oil and grease barrier properties.
Polyester-based emulsions are designed for use in food packaging grades. They provide an excellent balance of water, oil and grease resistance. Polyester-based emulsions are used to prevent edge wicking in label papers.
Acrylic/SB emulsions are excellent for use in barrier coatings. They are oil, grease, water, and moisture vapor resistant. Some of SNP’s acrylic/SB emulsions meet requirement for food contact.
SNP’s aqueous polyvinyl alcohol products for ideal for customers who:
Polyurethane dispersions (PUDs) are used in many grades of specialty papers. They provide high gloss, abrasive-resistant surface for decorative papers used in furniture, flooring and wall coverings; create faux leather surface in PU leather; create desired surface texture and feel in haptic papers; and are chemical resistant.
Ethylene acrylic acid (EAA) adheres to many different substrates including paper. It is an excellent heat seal material with good moisture vapor transmission resistance (MVTR) and good chemical resistance.
