Handle-it High Quality Machine Grade Film.  It is important to use the correct type of stretch film in our stretch wrap machines. There are many different manufactures and types of stretch film in the market. You must use machine grade film in our machines, or you will most likely see poor performance and film tearing. Hand grade films are not made to withstand the tension and stretch that a machine can put on the film. Our machines require 20'' wide machine grade film to feed through the carriage rollers properly, you can your narrower film but 20" is the most common.
