Here is the size chart for the most common roll sizes ordered by our customers. Since our customers were located in different places around the globe , different units are also being used , so we have created a size chart as a very convenient tool for our customers. Please remember that the weight and size of the boxes are all based on 1~2mil PET films. Any different material or thickness films will have different weight and size of boxes , thus please do not use this chart as a reference for the volume of your order to calculate your shipping costs.
