130°C Heat Sealable Polypropylene Coil

This heat-sealable PP Coil is a roll of isotactic polypropylene film engineered for controlled sealability, with heat seal initiation around 130 °C. It balances clarity, rigidity, and thermal integrity with food-safe, low-odor formulation. The coil is widely applied in flexible packaging systems, sterile barrier layers, retort pouches, and easy-open lids. Typical applications include boilable snack wrappers, cold-form seal trays, and medical blister covers. It plays an essential role in thermal bonding validation, peel force consistency testing, and mono-material recyclable film innovations. These PP coils are integral to studies on lamination interface behavior, heat-seal window optimization, and temperature-controlled transport packaging. Their use in reducing multilayer complexity in packaging aligns with sustainability goals and food safety compliance in high-speed manufacturing lines.
