The choice of a specific seal is often most strongly influenced by the type of tool or machine selected to apply it. |
|
Five standard seal types |
|
Snap-on seals |
|
Placed over the overlapping strap ends either during or after tensioning the strapping. Eliminates pre-threading. Speeds the strapping operation. |
|
 |
|
Thread-on seals |
|
Must be threaded over the overlapping strap ends before the tensioning tool is applied. Generally used on bales, bundles
and the larger strap sizes. |
|
 |
|
Open-flange seals |
|
Heavy-duty version of the snap-on. Requires no pre-threading. |
|
 |
|
Push-type seals |
|
Used where strap is tensioned by butting the nose of the tensioner against the seal. Overlapping flanges withstand the higher stress. |
|
 |
|
Nestack seals |
|
Held together by interlocking nibs. This Signode development permits loading partial stacks into magazines of
seal feed combination tools and power strapping machines |
|
 |
|
Microgrip seals |
|
For severe impact applications using waxed strapping. Microgrip seals are coated inside with a high-friction grit which bites through the wax to provide maximum holding power. |
