Paper & Packaging

VINNAPAS® polymer dispersions are used to formulate a broad range of paper and packaging adhesives. They are notable for their strong adhesion to a large number of substrates, very high heat resistance, excellent machinability and versatile formulation properties.

WACKER’s Technical Centers are equipped to test different formulations of paper and packaging adhesives. Here: Testing of setting speed.

Thanks to their copolymer composition, VINNAPAS® VAE dispersions can be applied to formulate plasticizer-free packaging adhesives with low migration potential and in compliance with major regulations regarding food-contact materials.

VINNAPAS® polyvinyl-acetate dispersions can be compounded to bond paper and paperboard in standard packaging and converting applications.

Benefits:

  • Excellent adhesion to difficult substrates
  • Very high setting speed
  • Strong adhesion / cohesion balance
  • Low-temperature flexibility
  • Good wetting
  • Compliant with food-contact regulations

Applications:

  • Case and carton sealing: e.g
    • Bags, pouches and sacks
    • Corrugated board
    • Folding boxes
    • Laminating
  • Paper board

Benefits:

  • Excellent adhesion to many substrates, including those of low surface energy
  • Low-temperature flexibility
  • Very high setting speed
  • Good wetting

Applications:

  • Aluminum foil converting, e.g., metalized film to paper
  • OPP film converting, e.g., surface-treated OPP film to paper
