Plastic or Steel Strapping?

Strapping materials come in three variations: steel, polyester (PET) and polypropylene (PP).

Steel was previously the most popular strapping material, favoured as it was the strongest, most durable and cost effective option available at the time. It is still used in a small amount of applications where there are no viable plastic options including awkward-shaped pipes and tubing and strapping temperature-sensitive products that may radiate heat through the strap.

However, plastic (PET) strapping is now the most  favoured product across all applications. PET strap is a safe, strong, effective and recyclable option that complies with all Australian operational standards and regulations

PP strapping is another type of plastic material strapping  that can be used to secure lighter items including small boxes, packaging cartons and small pallets. Due to its stretchy nature, it is not recommended for compressing large items or heavy products.

What Type of Strapping Machine is Right For Me?

FROMM engineers a range of strapping machines and tools for various industries and applications. The information found below will help you choose the right machine for your packaging needs.

  • Automatic Strapping Machines: These units are operatorless, with the cargo arriving via conveying systems. These machines remove the need for manual labour and can be categorised into two distinct types:

    • Automatic machines for inline applications such as boxes, totes etc.

    • Automatic machines for large items such as pallets ( bricks, timber, roof tiles etc.)

Automatic strapping machines feature automated processes for feeding, tensioning and cutting the strap, making them ideal for a high production environment

  • Semi-Automatic Strapping Machines: These strapping machines still require an operator to place and insert the strap, but the machine will correctly tension and seal the package. When choosing a semi-automatic strapping machine, flexibility and ease of use of operators are the largest benefits.

  • Horizontal Strapping Machines: Horizontal strapping machines strap cargo around their width, unitising tall column stacked cargoes. 

  • Vertical Strapping Machines: Automated vertical strapping machines apply straps around the load and sometimes through the pallet to unitise larger products.

  • Hand-Held Strapping Tools: There are a range of hand-held tools that can be used in a production environment, they can be manual, battery or pneumatic powered.

Strapping FAQs

Fundamentally you have a manual, semi manual or automated process.

 

Manual involves using hand tools such as tensioning devices and sealing devices ( sold separately) and a buckle or a clip to create the seal. Really only useful if you strap occasionally.

 

The rise of battery operated strapping tools has simplified the application of strapping with the material tensioned and sealed within the tool. Modern batteries mean up to 400 plus cycles per charge and these light weight ergonomic devices are very popular.

 

Automated processes are found in manufacturing and processing facilities such as timber mills, steel and aluminium smelters where cargo is not or do not fit onto a pallet. Growing in popularity is the rise of logistics and distribution where the application of strapping adds to the stability and also security of the cargo.

A strapping tool is a battery or pneumatic hand held device which requires an operator to apply the strapping around the product and using the machine tighten strapping, apply tension and seal.

 

A strapping machine is bespoke technology which is usually used as part of a process or manufacturing line. Strapping is fed around the product automatically by the machine, and applied with correct tension and sealing for an optimized product.

 

Automated strapping machines have a lot of "plug in" technologies such as bearer inserters, top and or bottom corners, top, and or side compression to square the load.

The strapping material starts in a plastic "state". Once tension is applied to it, it becomes elastic and can hold the load intact while providing some shock absorption. Apply too much tension, and it will lose the ability to absorb shock, putting the load at risk. As a general rule of thumb, more than 35% of the total breaking strain of the material is needed to create the elastic "state". Past the limit of 80%, the strapping material’s ability to absorb shock will be hindered.

 

A strapping machine will be able to consistently apply the right level of tension in the strapping material, making it easier and faster to pack items without worrying about their integrity.
