Poly Mailer Bag Mailing Courier & Shipping Envelopes

Our poly mailer bags — also called poly mailer envelopes, shipping bags, courier bags, mailing bags, or postal bags — are designed as a reliable and cost-effective solution for e-commerce, retail, and logistics. Made from strong polyethylene (PE), these bags provide lightweight protection, flexibility, and tear resistance while keeping freight costs low. With decades of experience in packaging, we deliver poly mailers that meet international shipping standards and are trusted by leading brands and logistics companies worldwide.

Material & Structure
We offer two material options:

• Virgin PE: glossy surface, higher stretchability, excellent tear resistance.

• Recycled PE: matte surface, usually in black, cost-effective, less stretchable.

Each bag is produced with a side-sealed structure and a self-seal adhesive flap for secure closure. The bags are bundled in packs of 100 with elastic banding and then packed into strong export cartons.

Customization Options

• Logo & Printing: support for single or multi-color printing. Multi-color artwork requires additional printing plates and ink adjustments.

• Sizes: dozens of stock sizes are available for immediate shipment; custom dimensions can be tailored to your specific needs.

• Color: white, black, gray, or fully customized color options.

• Eco Options: recycled and recyclable versions available for sustainable supply chains.

Applications
Poly mailers are ideal for non-fragile products that do not require bubble protection. They are widely used in:

• E-commerce fulfillment for clothing, scarves, textiles, handbags, and shoes

• Books, documents, and lightweight accessories

• Promotional packaging and brand campaigns

• Postal and courier deliveries where lightweight protection is critical

Unlike a Bubble Mailer, which has an inner cushioning layer, poly mailers focus on branding, scratch protection, and cost-efficient shipping. They are widely used by global retailers and e-commerce platforms because of their balance of durability, lightweight design, and affordability.

Performance & Quality
Our poly mailers meet the handling requirements of DHL, UPS, and FedEx. The strong PE film prevents accidental tearing and keeps goods safe throughout the delivery cycle. Production is certified under ISO 9001 and BSCI, and products carry RoHS and Reach certifications, ensuring compliance with European Union standards. These certifications make our mailers suitable for international clients who value safety, sustainability, and compliance.
