TEST PROCEDURE:

A total of twenty test samples were submitted for testing from the one Pallet Wrapz sample, and was subjected to a Tensile Test following the ASTM D 882 Standard Test Method/Procedure. This test determines the tensile properties of plastic in the form of thin sheeting, including film. The test identifies Peak Load, Peak Stress, and Break Elongation of the plastic sheeting/film material. The dimensions of each sample are 1.0 inch wide and 8.0 inches long. The rate of grip separation is set at 20 inches per minute.

GLOSSARY OF STRETCH WRAPPER TERMS

BANDING 
Putting multiple wraps of stretch film to certain areas of a load in order to reinforce the load.
BOTTOM WRAPS
The number of layers of stretch film that are applied to the bottom of a load.
FILM DANCER
A pivoting roller that measures the required film tension in a pre-stretch system. The dancer provides feedback to the control
system in order to compensate for the varied feed rate demands caused by the load corners and thus maintains constant film
tension during wrapping.
FILM FORCE TO LOAD
Also known as “film tension” or “film force”. The tensile force of the stretch film as it is applied to the pallet being wrapped
(measured in pounds of force between the load and film carriage).
FILM OVERWRAP
The length of stretch film that folds over the top of a wrapped load. Overwrap improves load retention and can be changed by
adjustment of the load sensing photo eye.
HOME POSITION
Position of the turntable and film carriage where the machine is ready to start a new wrap cycle and also finishes.
OVERLAP
The amount that a stretch wrap layer covers the previous layer on a wrapped load. Overlap improves load retention and can be
increased or decreased by adjusting carriage speed.
PRESTRETCH
The process of stretching film prior to application of the film to the load. As the film passes through the prestretch carriage it is
directed
