AI Overview
Rapid resilience waterborne polyurethanes (WPU/PUD) are advanced, sustainable, and high-performance materials designed for modern flexible packaging applications, including food pouches, print primers, and laminating adhesives. These dispersions, such as RHERI™U112 and SiwoPUD® series, provide high-speed compatibility, strong adhesion, and excellent flexibility, making them essential alternatives to solvent-based systems.
Key Characteristics and Performance
- Rapid Performance: Designed to support high-speed production lines and offer fast drying times for printing and lamination.
- High Flexibility & Toughness: They offer excellent elasticity, with some formulations featuring 1100% elongation and tensile strengths around 2.5 MPa, ensuring resistance to cracking and mechanical stress.
- Eco-Friendly and Safe: These formulations are typically toluene-free, ketone-free, NMP-free, and VOC-free, promoting sustainable, odor-free, and safe packaging (especially for food contact).
- Substrate Adhesion: They provide superior adhesion to varied substrates, including PET, BOPP, PVC, paper, and foil.
Applications in Flexible Packaging
- Laminating Adhesives: Used for bonding plastic to plastic (monomaterial) or foil, offering strong adhesion, high peel strength, and resistance to water and heat.
- Printing Inks: High-speed, water-based polyurethane binders are used in Gravure and Flexo printing on PET/BOPP films, offering excellent transfer properties, heat resistance, and self-healing properties against scratches.
- Surface Coatings: Providing barrier properties against grease, oil, and oxygen.
Common Product Solutions
- SiwoPUD®-1209 & 919F: Polyester-based, flexible, and fast-drying PU dispersions with excellent abrasion and water resistance.
- RHERI™U112: An aliphatic polyurethane dispersion designed for high-speed printing and laminating, offering high elongation.
- Sapici Waterborne PUDs: Used in combination with Cellulose Nano-Crystals (CNC) for improved barrier properties in food packaging.
These waterborne solutions allow converters to meet regulatory requirements while reducing carbon footprints and enhancing the aesthetic and protective quality of packaging.
