Polybag Size Chart & How to Measure

How to Measure Polybag Size

Measure the packed product’s length, width and height. The polybag must wrap over the thickness on both sides, so bag length = product length + height + margin, and bag width = product width + height + margin. Use a margin of 1 to 2 inches (about 2.5 to 5 cm) so the flap seals easily.

For example, a folded shirt of 10 × 8 inch and 1.5 inch thick needs a bag of about 12.5 × 10.5 inch with a 1 inch margin. Enter your numbers above in inches or cm and the calculator does it for you.
