Series: Wads
PP Induction Wads
Polypropylene (PP) is renowned in the packaging industry for its high tensile strength, excellent fatigue resistance, and significantly higher thermal tolerance compared to standard polyethylene formulations. In modern packaging, PP is the polymer of absolute choice for high-end cosmetic cream jars, hot-fill food containers, and rigorous retort sterilization applications. Consequently, PP induction wads require advanced heat seal layers capable of operating at highly elevated temperatures while successfully forming strong covalent and secondary bonds with the rigid, semi-crystalline PP container matrix.
