November 29, 2024 – LaserSharp Marking: Revolutionizing Eco-Friendly Packaging with Direct Laser Etching
In a groundbreaking collaboration, Procter & Gamble (P&G) and LasX Industries have successfully developed LaserSharp Marking, an innovative direct laser etching technology for packaging. This technique utilizes advanced laser pulses to create high-definition markings directly on package surfaces, replacing traditional label adhesion methods. Amid the growing “label-less” trend in the packaging market, numerous brands are embracing label-free packaging to reduce environmental impact and align with circular economy goals.
LaserSharp Marking offers multiple advantages over conventional labels. Firstly, from an eco-friendly and energy-saving perspective, it eliminates the need for PSA labels, shrink films, and inks, significantly reducing resource wastage and promoting sustainability. The markings are crisp, aesthetically pleasing, and capable of producing intricate patterns and text, enhancing the package’s visual appeal. Furthermore, the technology’s versatility allows for markings across various parts of the packaging, providing brands with greater design freedom.
According to Color Masterbatch Industry News, the core of LaserSharp Marking lies in its high-speed, high-precision laser pulses. Emitting millions of pulses per second, the laser beam precisely carves out various patterns and texts on packaging materials, enabling personalized customization and brand identification. This technology also effortlessly addresses challenges faced by traditional printing in handling serialization, language variations, or variable data, by directly applying digital, reconfigurable marks on package surfaces. This not only saves packaging space but also boosts production efficiency.
P&G is actively pursuing APR and RecyClass certifications for its HDPE, PE, and PET packaging products featuring LaserSharp Marking. LasX’s Vice President of Technology, Tom Wegman, expresses strong confidence in the technology, deeming it the future of packaging labeling. Meanwhile, Cajo Technologies has introduced another revolutionary laser marking technique, Cajo MakeBright, which rapidly generates precise and permanent markings on cardboard without any additives, combining eco-friendliness with efficiency.
The label-less packaging trend has gained traction in Europe, the United States, Japan, and South Korea. Evian’s debut of the first label-free, 100% recyclable rPET bottle in Singapore, Suntory’s limited-edition label-free green tea packaging in Japan, and amendments to Japan’s Act on the Promotion of Effective Utilization of Resources allowing the sale of beverages in label-free PET bottles exemplify this shift. In China, brands like Kangshifu Iced Tea, Sugar-Free Iced Tea, and Wanglaoji’s “Jijian Can” have also launched label-free PET bottle packaging, echoing the low-carbon and eco-friendly philosophy.
Labels are a crucial factor affecting product recyclability, requiring design considerations for easy separation from the bottle during recycling without causing contamination. In response, the China Synthetic Resin Association has issued relevant group standards, prioritizing labels in plastic recycling design. With the formulation and promotion of industry and national standards, the plastic recyclable design guideline system is becoming increasingly comprehensive, offering clear technical guidance to brands, packaging supply chains, and recycling enterprises.
In conclusion, the emergence of innovative direct laser etching technologies like LaserSharp Marking not only elevates packaging aesthetics and personalization capabilities but also plays a vital role in environmental protection, energy savings, and sustainable development. As relevant standards continue to evolve and gain traction, label-free packaging is poised to become a significant trend in the future packaging industry.
