Are you trying to package your item with a polyethylene bag but don't know the size?

Picking out a new dimension of poly bag to be used is really difficult. Not everyone is well-informed when equating the bag specifications to the products it is anticipated to carry. Here are the necessary things to think about when measuring its size.

Plastic bags are either flat or gusseted. Flat bags are two dimensional, while gusseted poly bags expand to add the dimension of depth. In either case, one must remember that the length and width sizes are measured when the poly bag is lying flat. In real-world use, the bag will be opened, thus any amount of increase will reduce the length. You will need to add that number to the length dimension to compensate for its loss.

The same is true with the width. Whereas gusseted bags generally eliminate this concern when accurately matched with the packed product, flat poly bags need an added adjustment on both width and length. This issues should be taken into consideration otherwise, you'll end up with worthless bags.

For instance: Mr. John, John wants to pack up his 8" x 12" books into a plastic bag. These books are 1/2" thick, and he ought to put 4 into each poly bag. That makes the capacity 8" x 2" x 12". He ought to allocate space for inserting the products without stretching it, hence the recommended specs for a flat poly bag would be" 11" x 16" long. That will hold his 10" of total good width (8" + 2") and 14" of total goods length (12" + 2") and allocate 2" more for him to close the poly bag with a tape or a heat seal.

Yes, there is a small amount of work involved in getting the right sized polyethylene bag, but if you take a few moments to take measurements you can avoid ordering the wrong bag for your needs.
