Strapping Core Size

We often get questions about core size measurements for strapping products. Just to make life a little more complicated, strapping machinery manufacturers decided to create machinery and manual dispensers that used a wide range of core sizes. This was originally done to create a proprietary strapping material that only a given machinery manufacturer could provide, but with those days long since passed, it’s now just one more confusing part of the packaging business. So below is an image to make it simple. Core sizes are listed as:

 CORE DIAMETER X CORE WIDTH.

For manual dispensers, the overwhelming majority of units use a 16” x 6” core size. All of Packaging Peddler’s polypropylene hand grade strapping and polyester hand grade strapping use this core size.

For machinery strapping, it’s important to be careful because the core sizes don’t vary by much. The most common size is 8” x 8” – though many machines use 9” x 8. Packaging Peddler offers strapping is both of these core sizes.
