1. How do I select the right strap for my application?
a.Steel strap is usually reserved for very heavy loads, greater than 5,000 lbs., for strapping high temperature loads, where plastic would melt, for loads with sharp edges, and for some round objects.
b.Polypropylene is used for lighter loads, lots of bundling (think newspapers), and carton closing.
c.Polyester is used for heavier pallets, tight non-compressible loads, like bricks, and as a replacement for steel.

d. Cord strapping is used in agricultural applications and as a manual way to unitize some heavy loads.

2. What if I need a machine, which is best?
The choice of what machine is right for your application depends on what material you specify, how fast you need to strap your product, and how automated you want the operation to be. Range of choices go from semi-automatic “Table Top “machines, perfect for UPS bundling, to machines that strap full pallets.
3. I’d like to get rid of steel strapping. It’s dangerous, can I use something else?
For the last few years many strap users have replaced steel strapping with JIAJUN WILLIE High Strength Polyester. While not every application can be switched, many can. Benefits of changing from steel to polyester may include:

oSubstantial Cost Savings
oA much safer material
oRust free and virtually impervious to normal conditions

It actually works better

4. Can I use the same tools with polyester as with steel?
Unfortunately, no. With the exception of your dispensers the sealing system is different with polyester, so you’ll have to switch to new tools. Keep in mind that for most applications, savings in the cost of polyester versus steel will make up for the cost of new tools in a few months.

5. How do you determine the proper number of straps per package?

It is up to the user to evaluate the suitability and safety of the individual application. Today all the "old rules" are changing as polyester is rapidly replacing steel strapping. The proper number of straps depends upon the load characteristics. Is the load shrinking, compressible, rigid, stable, expanding, etc.? How is the load to be shipped? Stored? Where? And for how long? The weight of the load is also important in determining the number of straps and break strength required. Pls contact us any time.

6. What is the difference between the various grades of strap?
Hand grade strapping is not made to the rigid tolerances required to feed strap reliably through automatic machines. Hand grade may have up to one splice. Semi-automatic grade has no splices and is made to higher tolerances than hand grade. Automatic machine grade strapping is manufactured to the highest tolerances and has no splices.

7.  Will hand tool grade straps work in automatic machines?
It may, but it will not work reliably or efficiently enough to justify the price difference and is not guaranteed by JIAJUN WILLIE for use other than hand grade applications.

8. Will JIAJUN WILLIE strap work in a competitor's machine?

Yes, JIAJUN WILLIE manufactures plastic strapping guaranteed to run in all manufacturers' equipment.
