How To Test Stretch Film Stretch Rate

The stretch films are a plastic film that is used to secure, parcel, and save the products. The stretch films are manufactured by using linear low-density polyethylenes. When you are applying the films around the products it will be pulled and stretched to obtain a tight and secured product load. It comes with a variety of widths, thicknesses, and colors.

These stretch film used to do exactly what the name implies, stretch. With the help of stretching a stretch film to the maximum stretch rate, all the companies save their money on film costs, and also they reduce their product loss. Some of the hand and stretch film machines commonly offer a different type of stretch rates. Many types of brands and resin formulas also offer different stretch rates. Here are given some simple steps below, that will help the companies to find out which amount of tightness is reached by hand or any mechanical equipment.

There are some steps to check the stretch rate of stretch film 

Tools and Materials Needed

The NewPack packaging experts suggest you by using a pallet of goods that is usually wrapped. Always remember that constant pallet loads namely Moving Boxes will usually obtain a higher stretch rate than loads with sharp edges or corners.

Calculator – To compute the simple mathematics

Marker – Specially use a permanent marker

Tape Measure – For measuring the lines

Pen and Paper – For writing the measurements

Ruler – It will help to draw a straight line

1. Always bind the stretch film all the corners of the pallet & make sure all pallets will be properly wrapped around the box.

2. After completing the last corner make sure is it reached completely for full rounds and loosely stretch it 5-6 ft. of the Stretch Film Roll and grip them until the Pallet Wrap.

3. After that hold the slack stretch film around the boxes and properly secure 3-5 ten-inch lengths on the film. All the lines should be separated aside a few inches beyond the length of the extra film pulled out in the second step. After making a ten-inch line it helps us to calculate and complete all the responsibilities in a very easy manner. Many lines should be marked on the film to get an average rate when one round of pallet wrapping.

4. Always wrap the pallet normally after completing 3-5 ten inch lines are properly marked on it. You can complete it with the help of your hand otherwise you can use any machine to do this task. And after it properly wrap it approximate 10 inches to the pallet.
5. Always use a tape measure which will help you to calculate the stretched lines and always write each line distance in a paper.

6. And the last step is that when all of the stretched lines are properly measured and written into a paper, calculate the average length of these lines by combining all lengths side by side and dividing by the total number of lines. When the average of all these lines comes 20, it means a 100% stretch rate is being reached. When the average of the lines is 30 inches, a 200% stretch rate is being reached.
