Suggested processing conditions
Scope of application
Supamid? TSA? Linear Tear enables straight-line easy-tear functionality when laminated with conventional PE, CPP, or BOPET films, while preserving the packaging's original structural integrity and strength. Ideal for liquid/semi-liquid products (soups, oils, sauces) and powdered goods, it effectively prevents content splashing/spillage during opening - significantly enhancing consumer experience.

The packaging made with TSA demonstrates remarkable user-friendliness: Effortless tearing benefits pharmaceutical/electronic packaging (protects fragile contents) and senior/child-friendly design for accessible food packaging.

Beyond standard applications, TSA excels in zipper bags requiring clean-cut openings, microwaveable stand-up pouch or other reusable packaging systems, and ready-to-eat convenience formats, delivering brand-enhancing presentation with every tear.
