Customer Questions & Answers

  • Question: What are UCGOU Poly Mailers made from?

    Answer: UCGOU Poly Mailers are made from sturdy polyethylene material, which provides strength and durability. This material is designed to withstand various shipping conditions, making it ideal for transporting items safely. Polyethylene is also waterproof and tear-resistant, ensuring that your contents stay protected from moisture and rough handling. As a result, these mailers are perfect for e-commerce businesses looking to securely ship clothing, accessories, and other soft goods.
  • Question: What is the weight capacity of UCGOU Poly Mailers?

    Answer: While specific weight capacity can vary based on the type of items being shipped, UCGOU Poly Mailers are designed to handle a substantial amount of weight typically associated with medium shipping needs. The strong construction allows them to securely transport multiple items or heavier soft goods without fear of tearing or breaking. This makes them suitable for businesses that frequently ship clothing, books, and similar products.
  • Question: Are UCGOU Poly Mailers reusable?

    Answer: No, UCGOU Poly Mailers are not designed to be reused. They are made for one-time use, ensuring that your items are packaged securely. However, they are cost-effective and recyclable, making them a responsible choice for eco-conscious businesses. By using these mailers, you can ensure your products reach customers intact while also maintaining an environmentally friendly approach.
  • Question: How do the self-sealing features work?

    Answer: UCGOU Poly Mailers come with a self-sealing adhesive strip, which makes sealing easy and efficient. Simply peel off the protective strip and press the flap down to seal. This feature not only saves time during packing but also ensures a strong closure that keeps contents secure during transit. It's especially useful for e-commerce businesses that process high volumes of shipments daily.
  • Question: What sizes are UCGOU Poly Mailers available in?

    Answer: The UCGOU Poly Mailers in question are 12x15.5 inches, making them versatile for a wide range of products. This medium size is ideal for shipping clothing, accessories, and other soft goods securely.

  • Question: Are these mailers waterproof?

    Answer: Yes, UCGOU Poly Mailers are waterproof, providing excellent protection against moisture during shipping. This is an essential feature, especially for items that could be damaged by rain or water exposure. Businesses that ship products in varying climates can rely on these mailers to ensure their shipments arrive in pristine condition.
  • Question: Can these mailers be printed on?

    Answer: UCGOU Poly Mailers are not designed for ink printing. However, many businesses choose to add printable labels directly on the surface for branding purposes. Using adhesive labels allows you to customize your shipping packages while ensuring clear delivery information. This is particularly useful for elevating brand presence and ensuring professional packaging.
  • Question: How many mailers are included in a pack?

    Answer: Each pack of UCGOU Poly Mailers includes 100 mailers, making it a bulk purchase that is perfect for small and medium-sized businesses.

  • Question: Do these mailers have any color options?

    Answer: The UCGOU Poly Mailers in this listing are navy blue, providing a professional appearance for shipments. However, UCGOU offers other color options for those interested in customization and brand representation.
