There are few types of strapping depending upon the product which suits with it.

a) Poly:

Oriented or tensilized polyester and nylon are the strongest plastic strapping products/tools and are used as a viable alternative to steel strapping in few industries. It provides excellent retained tension on rigid loads. Its excellent recovery properties help a load absorb impact without strap breakage. There are some specialized types available for specific applications. For instance, in cold climates a strap bonded in hot melt glue is used because it is weather-proof.

b)Cord:

Corded strapping is available in several constructions, primarily involving polyester and rayon. Some types are reusable. Because this system uses a buckle for a joint, corded strapping can have a larger system strength than steel banding. Corded polyester strapping also has a higher elongation than other strapping systems, which gives it an ideal memory for sea and rail shipments. Because corded  polyester straps are light weight and soft, they are also a safer alternative to steel banding.

c)Steel:

It is the oldest and highest tensile strength strapping. It is available in a variety of widths and thicknesses as well as variations in the grade of steel. Steel is used for heavy duty holding where high strength and minimal stretch are desired. It has common applications include steel coils, bundles of metal, baling wire, bricks and pavers, and roll end-binding. Steel Strapping is sold by weight rather than length, due to the natural expansion and contraction of steel in the manufacturing process.

This are the main types of strapping.
