Who Uses Poly Mailers?
Lightweight, flexible poly mailers are a practical alternative to rigid cartons for many non-fragile goods. Select packaging based on product dimensions, protection needs and carrier requirements.
Apparel & Fashion
Soft goods such as T-shirts, leggings, uniforms and lightweight garments.
E-commerce Fulfillment
Efficient packing for online stores, 3PLs and repeat parcel shipments.
Accessories & Textiles
Non-fragile accessories, fabric products and similar merchandise.
Warehousing & Distribution
Keep standard mailer sizes ready for recurring commercial shipping.
Why Choose Self-Seal Poly Mailers?
The adhesive flap helps speed up packing without requiring tape to close each bag. Flexible polyethylene bags can save storage space compared with many boxes and help shield contents from light moisture, dust and normal handling.
Poly mailers are not padded and are not intended to replace protective packaging for fragile or sharp items. If you need cushioning, see our Poly Bubble Mailers.

Frequently Asked Questions About Wholesale Poly Mailers
Are poly mailers suitable for fragile products?
Standard unpadded poly mailers work best for soft, non-fragile merchandise. For items needing impact protection, consider padded poly bubble mailers or corrugated boxes.

Our current catalog lists 6 × 9 through 24 × 36 inch poly mailers, with case quantities varying by size. The table above links to the individual product listings. Confirm availability before ordering.
Do poly mailers have a self-sealing closure?
Yes. The poly mailers in this collection have a self-seal adhesive closure, which helps speed up order packing.
Can I request wholesale pricing for recurring orders?
Yes. Provide the sizes, number of cases, purchase frequency and delivery ZIP code in the quote form. Pricing and availability depend on the requested products and volume.
