PVA 1788 for Paper Surface Sizing And Coating Food Grade

This medium-viscosity PVA 1788 is a partially hydrolyzed grade that dissolves in cold water, offering low foam generation and stable viscosity under high-speed stirring. It is designed for paper surface sizing and coating applications, improving smoothness, printability, oil resistance, and tensile strength. With low odor and food indirect contact suitability, it is ideal for food packaging and carton lamination.

Key Selling Points

Low Foam: Reduces foam formation during high-speed mixing, improving process efficiency.
Stable Viscosity: Maintains consistent performance under varying shear rates.
Improved Printability: Enhances ink holdout and surface smoothness for high-quality printing.
Oil Resistance: Provides a barrier against oil and grease, suitable for food packaging.
Food Contact Certified: Meets indirect food contact safety standards, low odor for consumer packaging.

Materials and Structure

PVA is a water-soluble polymer produced by alcoholysis of polyvinyl acetate (PVAc), offering excellent film-forming and binding properties.

Applications

Paper surface sizing
Coatings for high-gloss printing paper
Food packaging cardboard
Carton lamination
Book binding adhesives

Customization

We can adjust viscosity and mesh size within a range to meet specific production needs. Our technical team provides formulation support for paper coating.

Case Study

While we do not have a specific paper industry case study in our records, our PVA grades have been widely used in similar applications globally. We can provide technical support to optimize your paper coating formula.

FAQ

Can PVA 1788 be used for hot-melt adhesives?

PVA 1788 is water-based and not suitable for hot-melt systems. It is typically used in water-based adhesives and coatings.

Is this product suitable for food contact?

Yes, it meets indirect food contact safety standards, but we recommend checking with your local regulatory body for final compliance.

What is the dissolution process?

Add PVA 1788 slowly to cold water with gentle agitation. It dissolves within 30-60 minutes under continuous stirring. Avoid high shear to prevent foaming.

What is the MOQ?

5 tons, FOB/CIF.

Can you supply samples for testing?

Yes, we can send free samples. Contact our sales team.

Do you provide any certifications?

We provide COA, MSDS, TDS, and if required, certificate of origin.
