Custom Poly Mailer Shipping Bags

Ship lightweight products securely while creating a professional packaging experience with custom poly mailer shipping bags. Poly mailers are lightweight, self-sealing shipping bags designed for items that do not require the rigid protection of a cardboard box.

Imprint offers custom printed poly mailers, blank self-sealing poly mailers, and padded bubble mailers in multiple sizes for businesses, online sellers, retailers, and organizations with different packaging needs.

What Are Poly Mailer Shipping Bags?

Poly mailers are flexible shipping envelopes made from polyethylene film. They provide a lightweight alternative to boxes for shipping products that are not easily damaged by impact or compression.

The poly mailers available from Imprint are designed to help protect contents from dirt and moisture during shipping. Their self-sealing adhesive closure makes packages quick to prepare without requiring separate packing tape.

Poly mailers are commonly used to ship:

• T-shirts and other apparel
• Soft accessories
• Textiles
• Books and similar compact products
• Jewelry and small merchandise when appropriate
• E-commerce and retail orders
• Promotional merchandise
• Other lightweight, non-fragile products

For products that need additional cushioning, consider a padded bubble mailer instead.

Why Choose Poly Mailers for Shipping?

Lightweight Packaging

Poly mailers add relatively little packaging weight compared with corrugated boxes, making them a practical option when a rigid container is unnecessary.

Water-Resistant Material

Polyethylene construction helps protect packaged products from moisture encountered during ordinary handling and delivery.

Tear-Resistant Construction

The flexible material is designed to withstand the handling involved in packing, transportation, and delivery.

Self-Sealing Closure

An adhesive closure allows the bag to be sealed quickly without needing separate packing tape for the primary closure.

Space-Efficient Storage

Because empty poly mailers are flat and flexible, businesses can store substantial quantities without the storage space required for assembled shipping boxes.

Branding Opportunities

Custom poly mailers transform functional shipping packaging into branded packaging. Adding a logo, company name, artwork, or other design can make the package recognizable before the customer even opens the order.

Custom vs. Blank Poly Mailers

Choosing between custom and blank mailers depends on whether branding or simple shipping functionality is the priority.

Choose custom poly mailers when the shipping package is part of your customer experience or brand presentation.

Choose blank poly mailers when you primarily need simple, economical packaging for fulfillment.

Poly Mailers vs. Bubble Mailers vs. Shipping Boxes

The best shipping package depends on how much protection the product requires.

A standard poly mailer is usually appropriate when the product itself does not need substantial impact protection. If an item is fragile, easily crushed, or requires significant cushioning, use more protective packaging.

How to Choose the Right Poly Mailer Size

Choosing the correct mailer size helps prevent wasted packaging while leaving enough room to insert and seal the product.

A useful process is:

• Measure the length, width, and thickness of the product after folding or preparing it for shipment.
• Allow additional room for the item's thickness.
• Select a mailer that provides enough space to insert the product without stretching the bag.
• Leave sufficient material near the opening so the adhesive strip can close completely.

Smaller mailers work well for compact merchandise, while larger sizes are better suited to folded apparel and bulkier soft goods.

Avoid selecting a bag based only on the product's flat width and length. Product thickness also affects the usable interior space.

What Size Poly Mailer Do I Need?

The right size depends on the dimensions and thickness of the item being shipped. Imprint carries poly mailers ranging from compact sizes suitable for smaller merchandise to larger formats for apparel and other bulky, non-fragile products.

Always compare your packed product dimensions with the specifications of the individual mailer before ordering.

Poly mailers are particularly useful for T-shirts, clothing, textiles, and other soft merchandise that generally does not require rigid packaging.
