 |
Taper Band |
Standard sealing |
Strong standard seals |
 |
Reflex Band |
Vacuum packaging |
Less sealing force needed |
 |
Double Seam Band |
Stronger sealing |
Good for liquid packaging |
 |
Beaded Band |
Cut and seal |
Standard cut and seal applications |
 |
T-Profile Band |
Cut and seal |
Sharp cut and seal for medium to thick materials |
 |
Triangle Profile |
Cut and seal |
Best for thickest materials |
 |
Half Round Profile |
Cut and seal |
For cutting or sealing of thick materials |
 |
Oval Profile |
Pressure seal |
Produces a strong but narrow seal |
 |
Cutting Wire |
Cutting |
Used for rough cutting inadequate for sealing |
 |
Special Shapes |
Sealing |
Used to seal irregular or Profiles shapes or attach fitments |
 |
