Mailing Bags FAQs

What can you use as a postage bag?

There are several options you can use as a postage bag, depending on your needs and the items you are shipping. Some common postage bag options include:

  • Mailing Bags: These are lightweight, self-sealing bags made from materials like plastic or paper. They are often used for sending small items like clothing, accessories, and documents.
  • Bubble Mailers: Bubble mailers are padded envelopes with a bubble wrap lining on the inside, providing extra protection for delicate or fragile items during shipping.
  • Poly Mailers: Poly mailers are lightweight, water-resistant plastic bags commonly used for shipping non-fragile items like clothing, books, and other flat items.
  • Shipping Boxes: For larger or bulkier items, shipping boxes provide a sturdy and protective option for postage. They come in various sizes and can be easily sealed with packaging tape.
  • Gusseted Mailers: These expandable mailers have side folds (gussets) that allow them to accommodate thicker items, making them suitable for shipping items with irregular shapes or multiple items in one package.
  • Tyvek Envelopes: Tyvek envelopes are made from a durable, tear-resistant material and are often used for sending important documents or items requiring extra protection.
  • Padded Envelopes: Padded envelopes have a cushioned lining that provides protection for slightly delicate items during transit.

When choosing a postage bag, consider the size and weight of your items, the level of protection required, and any special handling needs. Macfarlane Packaging offers a wide range of options to fully meet your needs.

What is the purpose of mailing bags?

The purpose of mailing bags is to provide a convenient and secure packaging solution for sending items through the mail or shipping them via courier services. Mailing bags serve several essential purposes:

  • Protection: they’re designed to protect the contents from external elements, such as dust, dirt, moisture, and minor impacts, during transit.
  • Security: many bags feature tamper-evident seals or self-sealing adhesive strips to ensure the contents remain secure and prevent unauthorized access during shipping.
  • Versatility: this type of packaging comes in various sizes and materials, making them suitable for shipping a wide range of items, from documents and clothing to small products and non-fragile goods.
  • Lightweight and Cost-Effective: Mailing bags are lightweight, which helps reduce shipping costs, especially for items that don’t require heavy packaging.
  • Space-Saving: Mailing bags are often flat and flexible, taking up less space when stored compared to rigid packaging materials like boxes.
  • Eco-Friendly Options: Many postage bags are made from recyclable materials, providing a more environmentally friendly option for packaging and shipping.
  • Branding and Marketing: this type of packaging can be customised with branding, logos, and other designs, serving as a cost-effective way to promote a brand and create a professional image.
  • Postal Efficiency: Mailing bags are designed to meet postal regulations and fit within standard mailing and shipping requirements, ensuring smooth processing through postal and courier systems.
  • Convenience: Self-sealing adhesive strips or easy-to-use closures make postage bags user-friendly, saving time and effort during packaging.

Overall, mailing bags offer a practical, cost-effective, and efficient solution for sending various items through the mail or courier services, ensuring safe delivery to recipients while maintaining the integrity of the contents.

Can mailing bags be recycled?

The recyclability of mailing bags depends on the material they are made of. Here are common types of mailing bags and their recyclability:

  • Paper: postage bags made from paper are typically recyclable. They are made from paper or cardboard materials, which can be recycled through regular paper recycling programs. It is essential to remove any non-paper components like labels, tapes, or plastic windows before recycling.
  • Plastic: postage bags made from plastic are generally made from low-density polyethylene (LDPE). Some bags made from plastic can be recycled, but the recyclability depends on the recycling capabilities in your area. Many recycling centers accept LDPE and HDPE plastics for recycling. However, it is essential to check with your local recycling facilities to ensure they accept this type of bag. If they don’t, consider looking for specific recycling programs or drop-off locations that handle plastic film recycling.

Always check with your local recycling facilities to understand their guidelines on recycling and follow their instructions to ensure proper disposal and recycling of the bags.
