The SZIP Superproof will hold 750 mbar air pressure. The SZIP Superproof is less air-tight than the SZIP Superproof but is easier to open or close. Heavy bending may cause leakage. Please try to avoid!
The SZIP Superproof is highly resistant to damage caused by dirt or sand. However if dirt or sand are present, the zipper should be cleaned with soap and water. Dirt particles can affect the sealing function if they get caught between the teeth chains. If the SZIP Superproof closure is used to protect life or sensitive material, the sealing function and cleanness of the chain area should be double checked prior to every usage.
For the sealing function the SZIP Superproof requires a fairly strong pull of the slider. Please allow a slightly higher pulling force as compared to regular zippers. A wet surface or lubricant on the outer flanges of the sealing profile reduces the pulling force greatly.
