Allnex is rapidly enriching the COWISE™ CHOICE product portfolio and recently launched polyurethane dispersion PUD products with high barrier properties to provide sustainable solutions for the packaging industry. , promoting the industry to develop in a sustainable direction of high efficiency and recyclability.
At present, allnex has released products such as DAOTAN® TW6450/30WA, an environmentally friendly polyurethane dispersion suitable for a variety of applications, and DAOTAN® TW7000/40WA for enhanced printing inks and packaging.
Reusability of raw materials and environmental impact play a key role in solving the plastic waste problem. The latest developments in the allnex ECOWISE™ CHOICE range are a beacon of sustainable packaging design. Among the ECOWISE™ CHOICE product portfolio, waterborne PUDDAOTAN® TW6450/30WA was originally developed for automotive (OEM) primers and offers outstanding properties such as excellent elasticity, moisture resistance and good adhesion to various plastic and metallized substrates. Focus. It is suitable for specialty coatings, blister molding and packaging lamination. It contains low to zero VOC content.
ECOWISE™CHOICE water-based PUD
DOTATAN® TW7000/40WA combines high shear strength with flexibility. It has excellent adhesion to plastic and metallized substrates and is water and chemical resistant. It can be used as an ink (jet) binder due to its very good pigment compatibility, and its oxygen barrier properties make it suitable for packaging laminations and coatings. DAOTAN®TW7000/40WA is also suitable for automotive plastic coatings. It contains no solvents and contains low to zero VOCs.
In packaging applications, maintaining the functional requirements of food flexible packaging is a requirement for the packaging industry to move towards a circular economy. A common approach today is to use multiple substrate layers composed of different types of plastics to provide mechanical resistance and barrier properties. These layers need to preserve the nutrition, flavor and consistency of the packaged product while protecting against the ingress of water, sunlight (UV) and airborne contaminants.
Advanced Technologies offers innovative solutions for sustainable packaging materials while maintaining performance and protective properties. This contribution is critical to developing more environmentally friendly and circular packaging solutions that meet consumer demands, retailers and regulators. The concept of monomaterial packaging is growing in popularity in the pursuit of a circular economy. This design strategy involves creating packaging materials from a single type of material, thus greatly simplifying the recycling process.
Allnex’s polyurethane dispersions help facilitate this transition. By replacing various barrier coatings in multi-substrate packaging, PUD can create single-material packages without sacrificing the functional requirements of flexible packaging.
