Yawancin lokaci za ku ga kalmomi kamar haka:
"The seam peel strength shall be ≥ 1420 N for a 100mm cell depth, tested in accordance with ISO 13426-1 or ASTM D4437."
The "Minimum" vs. "Average" Tarko:
Ƙaƙƙarfan tallace-tallacen ababen more rayuwa (musamman na manyan titunan gwamnati) za su fayyace a Matsakaicin Matsakaicin Matsakaici (MARV) ko mafi ƙanƙanta.

- Ƙarfin Ƙarfafawa: "Minimum seam strength 1400N." (Wannan ya tabbatar kowane weld ɗin da aka gwada yana riƙe da kaya).
3.3 Abubuwan Haɓakawa ga Masu Kayayyaki
To meet a strict "Minimum" requirement, the manufacturer must have precise ultrasonic welding calibration. A "cold weld"—where the plastic didn't fuse deeply enough—will snap instantly during peel testing.
As a supplier, I ensure my production line monitors the dwell time and pressure of the ultrasonic horn for every batch. If a tender requires high seam strength, we often have to adjust the welding parameters specifically for that order, rather than using a standard "stock" saitin.
4. Abubuwan Baƙin Carbon: Tsare-tsare da Tunanin Juriya na UV
