What Kind of Stretch Wrap Do I Need?

March 25, 2020
Machine Stretch Film vs. Hand Wrap The first question is easy: how will you be applying your stretch wrap? Stretch film comes in both machine and hand grades. Hand stretch wrapping is done manually by simply winding the stretch film around the objects to be wrapped. Proper tension must be used to ensure a tight wrap and secure hold. Hand stretch film is designed for the job, with shorter, lighter rolls that can be comfortably applied by a human. Machine stretch wrapping is fast, easy and efficient. Machine wrapping can also reduce waste and provide a tighter and more consistent wrap for maximum load security. Stretch wrap machines may be fully automatic or semi-automatic. When machine wrapping, you must use a stretch film made for the job. The biggest difference between the two is in the stretch rate of the film, or the amount that the film can stretch before tearing. A film with a 100% stretch rate can double in length without tearing. Higher stretch rates result in less waste (you can wrap more with less film), lower costs and better tension. Hand film stretch rates are typically in the 75% to 150% range. Machine film stretch rates can be as high as 200%-250% or beyond. The higher the yield, the more you get for your money.
