The physical difference between the two formats
A pull tight strip seals uses a flat, wider strap profile, while a plastic pull-tight seal like the PSM-PP typically uses a rounder, narrower strap. This physical difference affects both how each seal handles and what closure points it fits best. JHAS
Why the flat strip profile suits certain closures
The flatter profile of a strip seal often threads more easily through wider or irregularly shaped closure points, bag zippers, box flaps, and similar openings where a rounder strap might not sit as securely.
Why the rounder profile suits other closures
A rounder plastic pull-tight seal, by contrast, often works better through smaller, more rounded openings, drum bungs, smaller container fittings, and similar points where a flat strip would not thread as cleanly. Follow us JHAS
Comparing strength and load capacity
Both formats offer reliable tamper evidence, but specific strength ratings can differ between strip and rounder profiles depending on the exact product line, making it worth confirming load capacity against your specific application’s demands. JHAS
Cost considerations between the two formats
Pricing between these two formats is generally comparable, meaning the choice usually comes down to which physical profile fits your specific closure point best, rather than a significant cost difference driving the decision.
How to decide which format fits your application
Examining the actual closure point you need to seal, its shape, size, and how the strap will need to thread through it, offers the most reliable way to determine which format will provide the most secure, practical fit. Follow us JHAS
