How to use

To use the BSTech PollyMailers, place your item inside the bag, ensuring it does not exceed the dimensions or weight capacity.

• Ensure the 50-micron thickness meets your durability requirements

Usage recommendations

For optimal results, ensure the bag is not overfilled to prevent stress on the seams. If shipping items with sharp edges, wrap them in protective paper or cardboard before inserting them into the mailing bag to maintain the integrity of the plastic.
