Poly Mailers: The Smart Choice for Soft Goods

If it doesn’t break when you drop it, it probably belongs in a poly mailer. Apparel brands, fabric stores, and accessory retailers have moved to poly bags because they solve the two biggest headaches in logistics: space and cost. A stack of 1,000 poly mailers takes up a fraction of the shelf space of 1,000 corrugated boxes. They require no assembly, just peel, seal, and ship. This efficiency allows smaller teams to pack more orders in less time, scaling your operation without scaling your warehouse footprint.

Engineering the Perfect Bag

Not all plastic bags are created equal. We focus on thickness, opacity, and seal strength to ensure your shipment is secure.

Material Specifications

• 2.5 Mil Polyethylene: The industry standard. It offers the perfect balance of flexibility and strength. Strong enough for a pair of jeans, light enough for a single t-shirt.

• 3.0+ Mil Heavy Duty: For bulkier items like winter coats or shoe boxes (yes, you can ship a shoe box in a poly mailer!). The extra thickness prevents the corners of the box from poking through.

• 100% Recycled Poly: Made from post-consumer waste. This option gives plastic a second life and appeals to eco-conscious consumers who want to minimize virgin plastic use.

• Biodegradable / Compostable: Plant-based alternatives (often made from cornstarch) that break down in home or industrial compost settings.

Functional Features of Poly Mailers

• Self-Sealing Adhesive: A high-strength adhesive strip that bonds permanently. Once sealed, the bag must be cut open, providing instant tamper evidence.

• Double Adhesive Strip: Features two adhesive lines with a perforation in between. This allows the customer to open the bag and reuse it for a return shipment using the second strip, a huge plus for apparel brands with free returns.

• Bottom Gusset: An expandable bottom fold that allows the bag to open wider for bulky items without stressing the side seams.

• Handle Bags: Die-cut handles at the top turn the mailer into a tote bag, adding convenience for customers picking up orders in-store (BOPIS).

Functional Features of Poly Mailers

Printing on flexible plastic requires specialized techniques to ensure the ink doesn’t crack or rub off.

• Full-Bleed Flexography: We can print edge-to-edge patterns, turning the entire bag into a branded texture (e.g., leopard print, floral, or logo repeat).

• Spot colors: Crisp, vibrant logos that stand out against the white or colored background of the bag.

• Matte vs. Gloss: Choose a glossy finish for vibrant color pop or a matte finish for a sophisticated, premium feel that feels less “plasticky.”
