HOW TO USE DIFFERENT TYPES OF STRAPPING MATERIAL

May 29, 2019

Pallet strapping, or banding is the process of using a metal or plastic strap to unitize, palletize or bundle products together. Strapping is used in a variety of industries from shipping large industrial equipment and lumber to reinforcing cases in e-commerce fulfilment centres. For this reason, there are many grades and types of materials on the market today.

Strapping is applied either manually with a hand tool or automatically with a strapping machine. In both cases, a strap or band is feed around the product and pulled taught. A fastening method then secures the ends of the strap around the product and the excess material is removed.

Strapping materials are available in many different strengths with specific grades and classifications. It is important to understand these grades and how they can affect your material choice when choosing your packaging. How your product is transported will affect the rating system and materials used. The two associations who grade strapping are the American Association of Railroads and ASTM International. Although ratings can be similar, it is important to understand that the designations are not interchangeable.

Types of Strapping Material

With a variety of applications and uses, it is important to understand the different types of strapping materials. The materials used come in multiple strength levels as well as elongation and recovery rates.

Elongation and recovery are important for loads that are susceptible to sudden shifting. The movement will apply tension to the strap as the load shifts. As the shifting occurs, a strap can stretch to reduce the impact of sudden inertia changes. The straps recovery ability of the strap will indicate the straps ability to return to its original state.

Steel Strapping

Steel strapping is the oldest and most commonly used banding materials to this day. Steel strapping is designed for extreme tasks that require a heavy or very heavy-duty strap. Steel strapping is optimal for packaging industrial equipment, heavy construction materials, and shipping steel coils.

Features & Benefits of Steel Strapping:

Large Loads
Hot Temperature
Sharp Edges
High Break Strength
Low Elongation Capabilities
UV Resistant
Extreme Durability

Steel strapping is applied manually with a tensioning tool and then fastened together by crimping a steel buckle around the bands ends. The excess steel strapping is then cut and disposed of.

Plastic Strapping

Plastic strapping materials are made from polyester, polypropylene and are available in a variety of strengths, styles, and finishes. Unlike steel strapping, elongation and recovery are a key factor for deciding which type of plastic strap to use.
