What Stands Out

Self-Seal Closure
The self-seal closure provides quick and hassle-free packing, ensuring items are securely sealed without the need for additional tape or glue, saving time for busy shippers.
Durable Material
Made from high-quality poly material, these mailers are tear-resistant and waterproof, offering excellent protection for contents during transit and ensuring package integrity.
Cubic Pricing
Designed with tiered cubic pricing, these mailers offer cost-effective shipping solutions for bulk items, making it easier for businesses to manage shipping costs and maximize profitability.

  • Question: What items can be shipped using these poly mailers?

    Answer: These poly mailers are perfect for shipping a variety of items, including clothing, textiles, and lightweight products. Their spacious dimensions of 18" x 18" allow you to pack several items together, making them ideal for bulk shipments. Businesses in the fashion and retail sectors often find these mailers convenient for sending out customer orders or promotional items.
  • Question: Are these mailers eco-friendly?

    Answer: While Bubblefast 18" x 18" Self-Seal Unlined Poly Mailers are made from durable plastic, they are not typically designed as biodegradable. However, companies using these mailers can focus on minimizing waste by reusing or recycling them where possible. For businesses considering eco-friendliness, these mailers can still be a cost-effective solution that offers longevity and strength when shipping goods.
  • Question: What is the cubic pricing tier for these poly mailers?

    Answer: The Bubblefast 18" x 18" Self-Seal Poly Mailers fall under Tier #5 cubic pricing, which means they are designed to optimize shipping costs based on volume rather than weight. This pricing strategy allows sellers to save on shipping when sending lightweight packages, making it especially beneficial for online retailers looking to manage operational costs effectively.
  • Question: How should I store my poly mailers for best results?

    Answer: To maintain the integrity of your Bubblefast 18" x 18" Self-Seal Poly Mailers, store them in a dry, cool place away from direct sunlight. Keeping them in a flat, organized stack prevents wrinkles or creases that could affect sealing. For businesses, designating a specific area for shipping supplies ensures efficiency when fulfilling orders and preparing parcels.
  • Question: Can I use these mailers to ship fragile items?

    Answer: While these poly mailers provide a strong outer layer, they do not include additional cushioning for fragile items. For delicate products, consider adding bubble wrap or foam padding inside the mailer to provide extra protection. This combination of materials ensures that even sensitive items arrive safely at their destination, particularly for businesses selling glassware or electronics.
