Strapping - A material used to preserve the integrity of a package or bundle numerous packages during transportation and storage. Steel Strapping - The strongest and most expensive strapping offered. Steel strapping is often used to unitize heavy loads. Polyester Strapping - A common substitute for steel strapping, the second strongest type of strapping available.

Nylon Strapping - Offers a high retained-tension capability and commonly used to unitize heavy loads. Polypropylene Strapping - The most common form of strapping, often used for unitizing and protecting smaller containers and boxes. Tensile Strength - A material's resistance to fracture when extended, stretched, and pulled apart, expressed in pounds. Cord Strapping - Commonly made from Polyester or Rayon, considered a heavy duty strapping material.

Core - The inner paper tube strapping is wound upon. Core measurements are measured in diameter and width. Embossed Strapping - Strapping with a rough texture.

Embossed strapping allows the strapping to grip the buckle closure better. Strapping Closure - Any form of seal or buckle to join two ends of strapping together. Strapping closures are most commonly made from plastic or metal. Solutions Packaging Supplies Guide: Everything you need to know about strapping. Guide: Everything you need to know about strapping.

There are multiple types of strapping products available, as well as many application types, but strapping is especially used in environments such as: Bundling together for handling and shipping: newspapers, pipe, lumber, concrete block, etc.

Attaching items to pallets, skids, and crates Reinforcing wooden boxes, crates, and corrugated boxes, such as gaylords Attaching items to flatcars, flatbed tractor trailers, etc. Securing a unit load of bricks, packaged glass, metal parts, etc. Closing corrugated boxes and shipping containers Securing coils of steel or paper Holding bales of agricultural products or textiles Load securing items within intermodal containers, boxcars, and tractor trailers Strapping is most often used in complete horizontal or vertical bands.

Main types of strapping available Steel strapping: steel is the oldest, strongest, and highest tensile strength strapping available. When it comes to knowing if you need something as heavy duty as steel strapping for your shipping, ask yourself these three questions: Is the load heavy and stable? Does it need to travel a long distance? Will it need to be loaded and unloaded many times before destination? Related Posts. Knowledge Base. Featured Posts. What is Cold Chain Packaging?

Of Labor. If however the bundle is a solid brick such as a block of concrete, the slack will be problematic. Additionally, the sun and its UV rays are an enemy to polypropylene strapping. UV degradation can occur is the bundle is left outside in the sun.

If the polypropylene strapping has been treated with UV inhibitors, then the strapping will fare better in the sun. Polypropylene strapping can be printed which has marketing advantages for companies.

The printing can also offer security. It is available in manual and machine grade. It can be sealed with buckles, seals, heat seals or friction welds. Polypropylene can be used for loads up to pounds, has moderate settling, is light weight.

Specific strength is defined as a material's strength force per unit area at failure divided by its density. In fiber or textile applications, tenacity is the usual measure of specific strength.

Nylon has been replaced by polyester. Polyester and nylon are the strongest plastic strapping products and are used as an alternative to steel in some applications. Polyester strapping can be woven or non woven. Woven Polyester strapping is even stronger than the composite straps due to the filaments being weaved together. Woven polyester strapping can be applied using a ratcheting tensioner and a high joint efficient buckle.

Steel strapping is the winner when you talk about time on the market. If the temperature of the metal is above its re crystallization temperature, then the process is known as hot rolling.

If the temperature of the metal is below its re crystallization temperature, the process is known as cold rolling. Steel strapping also comes in a variety of thicknesses and widths as well as variations in the grade of steel.

Break strengths can go as high as 12, pounds. Regular Duty RG strapping is usually a low carbon steel strapping produced for low to medium duty applications, e. Regular duty steel strapping can be used in manual and pneumatic tools, as well as automatic steel strapping heads. High Tensile HT : A high carbon steel strapping that is heat treated to produce a product which combines high strength and elongation stretch for shock resistance.

Typical applications are unitizing compressed fiber bales, securing heavy steel coils and open top rail car and trailer loading.
