Strapping Overview

Strapping ToolsStrapping has a lot of terminology and different things to consider when selecting the perfect strapping for your application. Things to think about:

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.

Cord Strapping

Manufactured from polyester fiber. Polyester fiber is one of the strongest synthetic fibers made. Commonly used in outdoor applications due to polyester cord’s excellent moisture resistance. Cord strapping is used only in manual applications and can be sealed using buckles and metal seals or hand tied.

Creep

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

Elongation

The percent 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 percent 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 feed wheel 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.

Polyester Strapping

The most rigid of all poly strapping materials. Polyester Strapping has superior tension retention and very low elongation. These characteristics make polyester strapping the choice strapping for empty bottles and cans, lumber and heavy rigid loads.

Polypropylene Strapping

The most common and least expensive strapping material available. High elongation and recovery but low retained tension make polypropylene strapping an excellent choice for light duty unitizing, bundling and carton closing.

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.
