In packaging, a secure cap seal is essential for product integrity. Softlon®, a cross-linked, closed-cell polyolefin foam from Sekisui Chemical, is the ideal material for high-performance cap seal applications. 

Why Softlon® is Perfect for Cap Seals 

• Exceptional Cushioning: Softlon’s fine-cell structure conforms perfectly to container rims, creating a tight, reliable seal that prevents leaks. 

• Superior Barrier: The closed-cell foam acts as a strong barrier against moisture and oxygen, preserving product freshness. 

• Inductive Sealing Compatible: Designed for use with inductive sealing, Softlon melts and bonds securely to the container, creating a hermetic, tamper-evident seal. 

• Durable and Lightweight: Softlon is resistant to many chemicals and is extremely lightweight, making it suitable for a wide range of products.
