In addition, Liofol Fast One stays within the specific migration limit (SML). The laminating adhesive is toxicologically safe in terms of Risk Phrase R40. No R40 labeling is necessary. "Our goal was to develop an adhesive that would enable just-in-time (JIT) manufacturing of flexible packages," says Georg Kinzelmann, corporate technical director, dead of the R&D platform for polyurethanes at Henkel. "With this unique one-component PUR laminating adhesive Liofol Fast One, curing is substantially reduced to just a few days, compared to a curing time of up to two weeks with a conventional adhesive".
The fast cure combined with a high initial tack enables packaging converters to bundle printing, lamination and cutting in a single step, increasing flexibility across the processing chain. In addition to time saving, the reduction of warehousing costs and lower capital employed are benefits that will be apparent to converters.
