Ethylene acrylic acid (EAA) copolymers provide exceptional adhesion, flexibility, and chemical resistance.  EAA is a copolymer of ethylene and acrylic acid, combining the toughness and flexibility of polyethylene with the polar functionality of acrylic acid.

Ethylene unit (x) provides crystallinity chemical, water and moisture resistance and acrylic acid unit (y) provides adhesion, polarity, toughness and strength. Through this combination, EAA copolymers provide resistance to various fluids while providing excellent physical resistance to puncture, tear and abrasion. This unique chemistry enables strong adhesion to polar substrates such as metals, glass, and ionomers—making EAA an ideal tie-layer or coating material in multilayer structures.

EAA copolymer dispersions:

  • Adhere well to many different surfaces including cellulosic, textile/nonwoven, treated and untreated film, metal, glass, concrete, and polymer foams.
  • Make excellent primers and tie-coatings as other coating materials adhere well to EAA.
  • Exhibit melt flow and wetting properties that make them a product of choice for use in aqueous heat seal compounds.

SNP’s S-1900-Series EAA co-polymer water-based dispersions are engineered to deliver:

  • Superior adhesion to polar and non-polar substrates
  • Excellent heat seal and hot tack performance
  • Resistance to environmental stress cracking
  • Low odor and taste, critical for food and medical applications
  • Puncture and tear resistance
  • Water dispersibility, enabling aqueous coatings
  • Excellent Adhesion: SNP’s EAA water-based dispersions offer strong adhesion to many substrates ensuring reliable seals with diverse packaging materials, including paper, film, foil, and metallized materials.
  • Lower Sealing Temperatures: The lower initiation temperature of EAA can improve packaging efficiency and reduce energy costs as compared to traditional polyethylene (PE) heat seals, starting at 65°C. Lower initiation temperatures may lead to faster packaging line speeds and reduced energy consumption.
  • Direct Food Contact Compliance: SNP’s EAA’s can be formulated to comply with direct food contact regulations, making them suitable for a broad range of food packaging applications.
  • Sustainable Packaging: Environmental concerns have led to a growing demand for sustainable eco-friendly and recyclable packaging solutions.  SNP’s EAA copolymer dispersions can be formulated to be compatible with the paper recycling processes. Sustainable paper and paperboard food packaging coated with EAA copolymers offers reduced environmental impact compared to alternative barrier coatings, because they can be recycled without significant issues
  1. Packaging Markets

EAA copolymers are widely used in flexible and rigid packaging due to their barrier properties and sealing performance:

  • Aseptic Packaging: Ensures sterility and shelf life for beverages and dairy.
  • Laminated Tubes: Used in cosmetics, pharmaceuticals, and toothpaste.
  • Condiment Pouches & Sachets: Provides seal integrity and resistance to oils and acids.
  • Dry Food Packaging: Offers moisture-resistance and durability.
  • Paper Coating: Enhances barrier properties and printability.

Application of Heat Seal Coating in Food Packaging:

  • Heat seal coatings are crucial for creating strong and reliable seals in various food packaging applications, ensuring product freshness and preventing contamination.
  • Flexible packaging, like pouches and bags, uses heat seal coatings to seal the packaging material, forming a secure enclosure for the food product.
  • Rigid packaging, like trays and containers, uses heat seal coatings for lid sealing, providing a tamper-evident and protective barrier.
  1. Non-Packaging Applications

Beyond packaging, EAA copolymers serve in diverse industrial and consumer markets:

  • Protective Films: For electronics, automotive, and construction.
  • Textiles & Nonwovens: Used in hygiene products and industrial fabrics.
  • Flooring & Furniture: Adds durability and chemical resistance.
  • Wire & Cable Coatings: Provides insulation and environmental protection.
  • Protective Metal Coatings: Prevents corrosion and enhances adhesion.
  • Digital Printing: EAA copolymer dispersions are use in HP Indigo printing as a primer to enhance adhesion of the liquid toner to the substrate.
