Ideal for e-commerce orders, clothing, textiles, soft goods, books, gifts and other non-fragile items being sent via post or courier.

Best used for

  • Online retailers and e-commerce brands shipping directly to customers
  • Clothing, textiles and soft goods that don’t require rigid boxes (for mailing bags)
  • Books, catalogues and printed literature (for book wraps and folder wraps)
  • Environmentally conscious businesses looking to reduce plastic in their packaging (paper products only)

How to use

  1. Place your product neatly inside the bag or wrap, ensuring it fits comfortably within the 250 x 350 mm internal size.
  2. If required, add extra protection such as tissue paper, bubble wrap or paper void fill to minimise movement.
  3. Fold or wrap the flap over tightly and seal using the self-adhesive strip or packaging tape (for wraps and sacks, secure all edges).
  4. Apply your shipping label to a clean, flat area and ensure any barcodes are clearly visible.
  5. For versions with two strips, leave the second strip intact so the customer can reseal the bag for easy returns.

Frequently asked questions

Are these recyclable?
All paper mailing bags, sacks and book wraps are widely recyclable in standard paper and cardboard recycling streams. Grey polythene mailing bags may be recyclable where soft plastics are accepted.
Do I need extra protection inside?
For soft items such as clothing, extra protection is usually not required. For books, files or more delicate products, we recommend using additional inner packaging or choosing a rigid book wrap or folder wrap.
Can these be used with Royal Mail and courier services?
Yes, the sizes are optimised for common Royal Mail and courier parcel formats. Always check your carrier’s current size and weight guidelines.
Can I write directly onto the surface?
Yes, you can handwrite addresses or apply printed labels. For best results, use a permanent marker or high-quality adhesive labels.
Are returns easy for customers?
Yes. Simply advise customers to cut along the opening edge and, where double strips are present, use the second strip to reseal, or secure with tape.
