The technical principle

The TIZIP SilverSeal is made from a strong, plastic coil zipper on a high strength fabric. Every coil half is safely embedded and secured in a plastic profile.

When the TIZIP SilverSeal is closed the sealing lips above and below the coil are compressed making a perfect seal. The entire plastic profile is highly abrasion resistant. The unique design prevents the slider from wearing down the sealing lips when the zipper is opened or closed.

The physical design of the TIZIP SilverSeal increases the seal strength when the pressure is raised or when cross tension is applied. Both actions lead to an increased mechanical pressure on the top sealing lip.

Tightness

The TIZIP SilverSeal is highly water resistant and splash proof. Heavy bending may cause leakage. Please try to avoid!

Dirt or Sand

The TIZIP SilverSeal 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 chain profiles. If the TIZIP SilverSeal 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.

Stability

The TIZIP SilverSeal´s performance in terms of strength and durability is outstanding. It can take weight, it is abrasion resistant and it will survive short term sharp bending and twisting without separating.

When closed, the TIZIP SilverSeal has a cross-breaking strength of minimum 300 N/cm.

However, in the event the TIZIP is over-stressed during closing, the chain may stay separated. In this case, simply move the slider back, reduce the cross tension, then reclose the zipper. The TIZIP will not be damaged by this procedure.

If the zipper has opened all the way down into the bottom stop, the first min. 2 cm have to be closed by hand before the slider is pulled back.

Follow the step by step instruction.

Versions

open top

Width: 50 mm und 70 mm
Chain width: 9 mm
Extensions over end stop and docking end: 16 mm or 25 mm

Operating Force

For the sealing function the TIZIP SilverSeal requires up to 2 kg to pull 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.
