What Is a Poly Mailer?

 

A poly mailer is a lightweight, tear-resistant plastic envelope used to ship soft goods and non-fragile items. Made from polyethylene (usually LDPE or co-extruded materials), these self-sealing bags are moisture-resistant, flexible, and highly durable.

 

Key features include:

Tamper-evident adhesive strip

Water- and dust-resistant material

Lightweight to reduce shipping cost

Available in multiple sizes, colors, and prints

Optional bubble lining for added protection

Common Uses for Poly Mailers

Poly mailers are ideal for shipping:

Apparel and fashion items

Books and magazines

Documents and office supplies

Health and beauty products

Small accessories (jewelry, phone cases, etc.)

Non-breakable retail goods

Unlike cardboard boxes, mailers conform to the shape of the product, taking up less space and reducing dimensional shipping fees.

Seal quality: Strong adhesive strips to prevent tampering or opening during transit

Opacity: Especially important for privacy and security (white or black layers inside)

Size accuracy: Be sure your dimensions match the intended product categories

Certifications: For food-safe, recyclable, or eco-friendly claims

Pro tip: Ask for samples before placing a large order.
