Thickness is one of the most important factors for pricing of packaging bags.

Below are some commonly used units for thickness and their conversions.

Here are some regular thicknesses you can take as references for different types of packaging bags.

For regular plastic mailing bags in virgin material, minimum thickness suggested is 60 microns while maximum to be 150 microns. To choose which thickness depends on the weight you need to use the mailing bag to carry. Most commonly used thicknesses are 60/65/70/75/80 microns.

For recycled material, minimum can be 60 microns but we suggest 70 microns minimum to maintain a better tearing strength. Maximum to be 150 microns. Most commonly used thicknesses are 70/75/80 microns.
