Sustainable Surface Treatments

What’s next for sustainable CMF in packaging? Sustainability in packaging is no longer defined by materials alone, it’s increasingly expressed through CMF strategy. CMF is evolving from a surface treatment to a system of sensory communication, shaping how users perceive value, authenticity and responsibility. In one of our recent project, we re-evaluated how CMF decisions could serve both environmental performance and emotional connection. Three insights emerged: 🟠Color as a signal of responsibility Moving from synthetic pigments to bio-based mineral dyes reduced VOC emissions by 25%, but more importantly, it shifted the brand’s visual tone toward natural warmth and material honesty. The palette became part of the sustainability narrative: subtle, muted and grounded in origin. 🟠Material as an ecosystem enabler By replacing multi-material laminates with mono-material recycled polypropylene, we achieved 98% recyclate purity and simplified disassembly. This wasn’t just a technical gain, it reframed packaging as part of a circular materials ecosystem, where design anticipates recovery rather than waste. 🟠Finish as tactile storytelling Transitioning to low-gloss, matte micro-textures cut solvent use by 40% and reduced coating layers, but it also redefined the tactile experience. The surface now communicates a more authentic, uncoated honesty, an aesthetic of restraint that resonates with the values of transparency and longevity. Together, these CMF shifts illustrate a broader truth: sustainable design isn’t a subtraction of beauty, but a recalibration of meaning. When color, material, and finish are intentionally aligned with lifecycle thinking, the product itself becomes a narrative of responsibility #cmf #packaging

Laser surface preparation is poised to revolutionize traditional surface preparation methods, offering several key advantages that are becoming increasingly evident as the technology matures and gains wider adoption. Here’s why laser surface preparation is likely to change the landscape:  1. Precision Profiling   - Consistent Surface Profile: Laser profiling can achieve a highly consistent surface profile, typically in the range of 40-200 microns. This level of precision is essential for applications like coatings, where even minor deviations can affect performance. For example, coatings such as EonCoat require a specific 100micron surface profile to bond effectively, and Pulse Tech Lasers is able to deliver this on our job sites  2. Effective Salt Removal   - Chloride Salt Elimination: One of the significant challenges in traditional surface preparation is the removal of chloride salts, which can lead to osmotic blistering under coatings. Lasers excel in this area, effectively removing these salts and thereby reducing the risk of osmotic action that can compromise coating integrity.  3. Abrasive-Free Technology   - Cost and Environmental Benefits: Traditional methods often rely on abrasive materials, which can be costly and environmentally harmful, especially when dealing with toxic coatings. Laser surface preparation eliminates the need for abrasives, making the process cleaner, more sustainable, and safer for operators, particularly in sensitive environments.  4. Potential for Automation   - Increased Throughput: Laser systems can be easily integrated into automated processes. Maintaining a precise spot size and positioning is crucial, and automation makes this easier, potentially doubling the throughput of surface preparation tasks. This is especially beneficial for large-scale infrastructure projects where efficiency and speed are critical.  5. Emerging Adoption in Large-Scale Projects   - Proven Results in Infrastructure: While laser surface preparation has been a staple in small-scale manufacturing for years, it is now being trialed and successfully implemented in large-scale infrastructure projects. The results have been exceptional, suggesting that this technology is ready for broader adoption.  6. Western Australia as a Hub   - Leading the Way: Western Australia is emerging as a leader in the adoption and development of laser surface preparation technology. With companies actively exploring and utilizing this technology, the region is set to be at the forefront of this technological shift.
