TECHNOLOGIES & TECHNIQUES Table 4. Availability for Use FDA Regulation Solventless Water Base Solvent Base 175.105 ./ ./ ./ 177.1390 ./ X ./ 177.1395 ./ ./ ./ ABOUT THE AUTHOR: Larry Jopko is technical service manager, North America Region, Packaging and Industrial Adhesives, Specialty Materials Group. He has 10 years of experience in converting and 24 years on the supply side, mainly in adhesives, coatings, heat seal coat- ings, barrier,.fùnctional coatings. Michael Leib has been with Rohm and Haas for 23 years. In his tenure he has held positions such as RB[D chemist, technical service chemist and is currently a technical service manager in the Flexible Packaging Group. A reputable solventless adhesive supplier will list the FDA Regulations to which the adhesive complies, as well as appropri- ate recommendations for intended use to ensure safety in the packaging for food supply (Table 4). CURE BY TECHNOLOGY One of the advantages of current sol- ventless adhesives is that the chemistry is well known and has been in use for decades, based on urethane chemistry developed first as solvent-based adhesives. The history of performance is known and generates confidence in use. With new advancements in chemistry, the same ap- proach of urethane chemistry is now much safer for the workers and can cure in a very fast time to produce fit-for-use packaging in a relatively short time. Many current sol- ventless adhesives now cure as fast, if not faster than, their solvent-born analogues. Overweight. ( Are heavy anilox sleeves straining ) your back - and your budget? FUTURE DIRECTIONS The progress of the solventless adhe- sive technology continues. Various new approaches and cure mechanisms are being explored, including: · Bio-based raw materials, which re- duce petroleum-based materials. · Non-isocyanate curing, which further enhances safety. · Energy-assist curing (electron beam or UV light), which cure faster. · Faster-cure mechanisms that retain ease of use. Lighten up your anilox sleeves. Weightlifting is forthe gym. You need durable, lightweight sleeves in your pressroom for safe loading and unloading. You want Apex UltraQuick. sleeves because they're the best money can buy. Our aluminum TruCore T . sleeve design cuts 33% to 50% in weight and delivers peak ani lox performance. Coupled with UltraCele laser engravings, you get the highest ink-release in the industry - and the absolute lowest inside and outside TJR. With zero bounce. How? Only Apex makes both the sleeves and the engrav- ings from the ground up, not just repurposing other sleeve applications. Given the current state of solventless adhesives, there are clear advantages in economy, energy use and efficiency compared to conventional solvent- and water-based adhesives. Solventless now covers all of the foreseen applications for lamination of packaging, from simple snack laminations to the very demanding medical, high-heat sterilizable and retort packaging. For new installations of lami- nation capacity, solventless adhesive use should be considered as one of the prime approaches. .
