Allegro® M sealant addresses pharma/medical device ‘clean peel’ lidding issues


Pharmaceutical and medical device manufacturers looking to solve “clean peel” lidding issues can now benefit from Rollprint Packaging Products, Inc. proprietary Allegro® M sealant. The sealant can be extrusion coated onto various substrates including film, foil or even paper to create a cost effective way to a achieve a “clean peel.” The sealant seals to numerous rigid cup or tray structures including high-impact polystyrene (HIPS), polyvinyl chloride (PVC), amorphous polyethylene terephthalate (APET), polypropylene (PP) and high-density polyethylene (HDPE). Allegro® M seals at low temperatures and also offers a wide operating window. Further, it frequently offers improved peelability at lower-cost than competitive products. The sealant is ideal for more challenging applications, including those that might be tough-to-seal due to liquid contamination on the sealing surface. Typical applications include unit-of-use liquid medications, diagnostic cartridges, pre-filled syringes and medical devices. Allegro® M’s sealing properties help the lidding structures stand up to transport challenges, thereby minimizing the chance of compromise. Allegro® M’s “no residue” clean peel offers a positive visual aesthetic. Additionally, it has a good thermal and dimensional stability and it is also suitable for radiation sterilization.
