The combined technologies of MeadWestvaco and Honeywell have produced a new substrate choice for high barrier blister packaging.
MeadWestvaco’s Packaging Resources Group developed a paperboard that seals consistently to Honeywell’s high moisture barrier film Aclar. Printkote EasySeal Plus achieves a fiber-tear bond to Aclar in heat seal applications.
According to William Sharpless, senior healthcare specialist for Honeywell’s Specialty Films Division, EasySeal Plus is the first paperboard to sustain this level of performance with the barrier film.
“EasySeal Plus gives pharmaceutical companies a more complete range of substrate options that can be used with Aclar in blister-card applications.
This paperboard [Printkote EasySeal Plus] has proven itself to be a viable option in addition to PVC, PETG, APET and PP, removing any potential barriers that would prevent a packaging engineer from using Aclar.”
An additional advantage is the ability to seal at low temperatures with short dwell times. This results in faster line speeds and less product and ink degradation. It is also said to lower packaging costs compared with press-applied coatings.
