How To Measure For Shrink Wrap

If a product is 10 inches wide and 4 inches high, you can add 10 + 4 + 2 = 16. 16 inches wide film is ideal for packaging products. If a 16-inch film is not available, use the next size up and do not use the next size down.
Shrink Wrap Tubes – To measure shrink wrap tubes, measure the circumference of the widest point of the object, then add 10-15% and divide by 2.

If an object has a circumference of 10, then the equation is: 10 x 10% = 1, then add 1 to the circumference 10 + 1 = 11 and divide by 2 11/2 = 5.5 in. A 6 in. wide shrink wrap tube would be ideal for this object.
If there is no available 6″ size, feel free to increase the width of the tube to the next size up.

Shrink Wrap Bags – The measurement of a shrink wrap bag is very similar to the measurement of a shrink wrap tube. Measure the circumference of the widest point of the object being wrapped.

Then measure the length of the wrapped product. Add 10-15% to the circumference of the width and divide by 2. If you have a product with a width circumference of 14 inches and a length of 20 inches, then the formula is

Find the width 14 x 10% = 1.4, then add 1.4 to the circumference 14 + 1.4 = 15.4 and divide by 2 15.4/2 = 7.7. A bag that is 8 inches wide.

The length is 20 inches. You will need an 8 x 20 inch bag to package the product. If that size bag is not available, you can choose to increase the size.
