Ideal for Ecommerce, Clothing & Parcel Shipping
Grey mailing bags are a popular choice for online retailers, warehouses, fulfilment operations, clothing sellers and businesses sending non-fragile goods. They are particularly useful for clothing, textiles, accessories and other products that do not require a rigid box.
For fragile, sharp or easily crushed products, use suitable protective packaging rather than relying on a mailing bag alone.
How to Choose the Right Mailing Bag Size
Measure the widest and longest points of the packed item and allow enough room to insert it comfortably and close the adhesive flap without stretching the film. Choosing a close-fitting size can improve presentation and reduce unnecessary packaging.

Are Recycled Mailing Bags Recyclable?
Yes. The supplier specifies that the LDPE film is recyclable once the adhesive strip is removed. Recycling depends on local facilities and soft-plastic collection availability. These plastic mailing bags are not biodegradable or compostable. Choosing 100% recycled content helps reduce reliance on virgin plastic, but no packaging is impact-free.
