What is PET Strapping?

First, it's important to know that PET strapping is made from the same material as plastic beverage bottles (PET). It's known for being:

Application Process: Step-by-Step

The application of PET strapping can be manual, semi-automatic, or fully automatic, but the core principles remain the same.

Step 1: Choosing the Right Strapping

Select the appropriate size (width and thickness) and strength of PET strapping based on the weight, size, and stability requirements of your load. For example, a heavy, dense load like bricks requires thicker, stronger strapping than a light load of empty cardboard boxes.

Step 2: Positioning the Strapping Around the Load

The strapping coil is placed on a dispenser or fed through an automatic machine. The strap is guided around the load (e.g., a stack of boxes on a pallet).

• Manual/Semi-Automatic: The operator pulls the strap from a dispenser and wraps it around the load by hand.
• Automatic: The machine has an arm or carriage that automatically wraps the strap around the pallet.

Step 3: Tensioning

This is the most critical step. The strapping is pulled tight to secure the load.

• How it works: A tensioner (built into a tool or machine) grips the strap and pulls it with a specific force. PET strapping's elasticity allows it to be stretched, which creates a constant clamping force on the load. This force compensates for any slight compression or shifting during shipping.
• Goal: Apply enough tension to secure the load without damaging the goods or breaking the strap.

Step 4: Sealing (Joining the Ends)

Once the desired tension is achieved, the two ends of the strap must be joined to form a secure loop. There are two primary methods for sealing PET strapping:

Friction Weld (Heat Seal): This is the most common and strongest method.

• ​​Process: The two overlapping ends of the strap are rubbed together at high speed under pressure. The friction generates heat, melting the PET and fusing the ends into a single, monolithic piece.
• Equipment: Used by semi-automatic tools and automatic machines.
• Advantage: The seal is as strong as the strap itself.

Metal Seals (Crimping):

• ​​Process: A pre-formed metal seal (a small, flat piece of metal) is placed around the two overlapping ends. A tool called a "sealer" or "crimper" compresses the seal, deforming it and mechanically locking the straps in place.
• Equipment: Used with manual tensioners and some specific heavy-duty applications.
• Advantage: Does not require electricity, making it useful in certain environments.

Step 5: Cutting

After the seal is made, the strap is cut from the coil. In automated systems, this happens instantly after sealing. With manual tools, the operator often uses the tool's built-in cutter or a separate knife.
