5-19mm Width PP Packing Belt Smooth Feeding Fits Manual Semi Automatic Fully Automatic Strapping Machines Polypropylene Strapping

A good strap still fails if it is set up on the wrong machine settings. Follow the steps below and the same roll will run all day without jams or broken joints.

Manual tensioners and battery tools pull slowly and accept a 5mm to 19mm strap. Semi automatic and fully automatic machines need a strap that is straight, evenly wound and matched to the arch size. Check the machine manual for the accepted width, thickness and core diameter before ordering.

• Place the coil on the dispenser so the strap unwinds without twisting.
• Keep the strap path straight through the guide rollers; a twist causes the weld to skew.
• Leave enough free length to thread the arch before starting the first cycle.

Start low and increase gradually. The correct tension is the point where the carton corners stop moving but the board is not crushed. PP strap stretches under load, so a light initial tension that settles after a few hours holds better than a hard pull that necks the strap.

PP strap is joined by friction weld: the machine rubs the two ends at speed, melts the surface, then presses and cools them. Keep the welding time within the machine setting; too short a time gives a weak joint, too long a time burns the strap. Pull the joint once by hand after the first cycle of every new roll.

• Store coils indoors, dry, off the floor and away from direct sunlight.
• Use the oldest stock first; polypropylene ages faster in heat.
• Clean the feed wheel and cutter weekly to keep width and joint quality stable.
