Bag thickness affects strength, appearance, material consumption, and run price. For T-shirt bags, 30, 40, and 50 microns are the most common comparison points.
30 microns
Suitable for light goods and situations where the bag is used briefly. It is an economical option for low loads, but it should not be used for heavy or sharp products.
40 microns
A universal balance between cost and strength. Stores often choose it when the assortment varies and one basic bag is needed for most purchases.
50 microns
A denser option for heavier products, a more solid bag feel, and increased handle reliability. It costs more, but may fit the brand better when the bag needs to feel more substantial.
How to decide
Estimate average product weight, maximum load, customer expectations, and budget. If unsure, compare several options by price and purpose.
