Break Strength
The amount of force required to break the strapping is expressed in pounds.

Camber
The side to side curvature of strapping. Machine grade strapping must be camber free to allow the strapping to move through the equipment.

Creep
The loss of the strapping tension that occurs over a period of time.

Elongation
The % of stretch in the strapping as force or tension is applied.

Elongation Recovery
The strap's ability to return to its original state after tensioning.

Embossing
The textured pattern applied to the strapping surface. Quality embossing will increase joint efficiency, enhance split resistance and improve stiffness characteristics. However, an overly embossed strap can increase the thickness and lower break strength.

Joint Efficiency
The usable strength of strapping is only as powerful as the joint holding the two strap ends together. Joint efficiency is expressed as a % of the total breaking strength of the strapping.

Knurling
The embossing found on the surface of polypropylene strapping. The feed wheels in strapping equipment grip the embossed strapping to carry the strapping through the equipment. Low knurling can cause miss feeds and strapping jams.

Feed Wheel Tensioner
Tensions painted or waxed steel strapping on a flat surface. This strapping tensioner has serrated feedwheel that grips the strapping.

Front-action Sealer
Handles are held perpendicular to the strapping and usually in front of the operator. Handles are pushed together to crimp the strapping seal. For light duty strapping applications.

Push Type Tensioner
Tensions painted or waxed steel strapping on irregular or round bundles. The steel strapping is engaged by a serrated feed wheel.

Rack-and-Pinion Tensioner
Tensions dry or lubricated steel strapping on round or irregular shaped packages. Uses a serrated gripping dog to hold the pulled steel strap end. Has limited strapping take up.

Shock Resistance
The ability of strapping to stretch and return to its original state upon impact without breaking.

Side-action Sealer
Lower handle can be laid on a flat surface enabling the operator to use both hands on the upper handle to apply more force on the strapping seal . For heavy duty strapping applications.

Split Resistance
The ability of strapping to resist lateral tearing.

Steel Strapping
Is the strongest strapping material made. Recommending strapping where high strength is necessary and low elongation is important. Ideal for very sharp and extremely hot products.

Windlass Tensioner
Primarily used with dry heavy strapping for extra heavy- duty applications. The windlass tensioner winds one end of the steel strapping around a slotted windlass shaft. Strapping must be pre-cut to desired lengths.
