Flexible film packaging systems, often laminated with foil or paper, are increasingly popular alternatives for packaging food and other goods. Our specialty coatings are creating virtually limitless performance possibilities for these new end use products:
A small amount of a Michelman wax emulsion can improve slip, block and barrier properties without affecting gloss, printability or heat sealability. Carnauba waxes are preferred for their excellent lubricity and favorable food contact status. Polyethylenes and montans are also used.
Low heat-seal temperature Michem® Prime co-polymer dispersions allow packagers to laminate different films together and use lower coating weights. As a primer, Michem® Prime provides an ink receptive surface compatible with most digital and conventional printing processes. Michem® Prime is clear, FDA-compliant, and resistant to water, grease and many solvents.
Meeting the Diverse Needs of A Wide Range of End Uses
Customers count on Michelman’s technical experts for solutions that meet the specific requirements of their end uses. Most requests include one or more of the following needs:
Barrier Properties. Packaging for snack foods, dry foods, confections, pet foods, flavored coffee and pharmaceuticals all need varying barrier properties such as water resistance, oil resistance, aroma and oxygen barrier.
Heat Sealability. Packaging for many of the above products, plus yogurt and frozen foods can also require low heat seal temperatures. Low coating weights and faster line speeds are frequently desireable.
Top Coats. Cigarette foils and a number of the packages mentioned above need multi-substrate products that provide print protection, gloss and short dry times.
Wet and Dry Bond Laminating Adhesives. These are used on the packaging for sweets, yogurt, soups, snack foods, dry foods, confections and pet foods. Long storage ability, fast curing and blister avoidance are the primary concerns.
Primers. Metallized films for sweets packaging, dry foods, confections, pet foods, shrink films, specialty films and foil primers all require multi-substrate products that offer good adhesion strength, low foaming, short cure times and low cure temperatures.
