Bio-Based Compostable Pressure Sensitive Adhesive

KEY INFORMATION
Chemicals - Bio-based
TECHNOLOGY OVERVIEW
Pressure sensitive adhesives (PSAs) are viscous resins that are designed to adhere to various substrates under light pressure. Majority of commercially available PSAs are derived from non-renewable petroleum sources such as acrylics and silicones, providing the required bonding performance for either permanent or removable applications for use in labels and packaging. However, conventional PSAs present environmental concerns at their end of life, even when its substrate is biodegradable.
The technology on offer is a patented bio-based, compostable PSAs comprising of 95% soy and other bio-derived materials that costs less than petroleum adhesives. These PSAs can bond to a variety of substrates (including paper and foams), contains no solvent or water, lowers CO2 emissions when compared to conventional PSA. It can be applied using standard application techniques (slot die or gravure systems) and upon curing will result in a light, cream coloured film.
The technology owner is seeking for R&D collaborations and IP licensing opportunities with Singapore partners to manufacture/utilise the technology in packaging and non-structural applications.
TECHNOLOGY FEATURES & SPECIFICATIONS
The technology is a soy-based, hot melt PSA that enables excellent adhesion to a variety of substrates.
Some features of the technology include:
- Does not contain water or solvent
- Comparable adhesive performance to petroleum-based PSAs
- Net negative CO2 emissions - 0.79kg CO2 sequestered per 1 kg manufactured
- Costs 20% less than competing petroleum-based PSAs
- Home compostable (ASTM 6400/EN 13432) and industrial compostable (ASTM 5511)
- Applied using standard application techniques such as slot die and gravure systems
- Can be UV or thermal cured
- Can be designed to be removable or permanent for labels and tapes
POTENTIAL APPLICATIONS
Potential applications include (but are not limited to):
- Packaging such as flexible and paper-based
- Tapes
- Labels
- Protective films
- Commercial applications that require compostable, bio-based alternatives to acrylic
Market Trends & Opportunities
The pressure sensitive adhesives market is projected to grow from USD 13.2 billion in 2022 to USD 16.9 billion by 2027, at a CAGR of 5.1% between 2022 and 2027. With this technology, companies will be able to move away from fossil-based PSAs and achieve their environmental, social and governance goals to combat climate change.
