Product FAQs
How do I use heavy duty mailing bags?
- Choose the appropriate size, the bag should be large enough to contain the item without too much excess space, but not so tight that it strains the seams and compromises the effectiveness of the packaging, which is there to protect the item(s) inside
- Secure the item, if the item is fragile, consider wrapping it in additional protective materials, such as bubble wrap or tissue paper before placing into the bag. Adding void fill into any empty space left inside of the bag minimises movement and risk of damage to the item(s) inside
Tip: heavy duty kraft paper bags with gussets can be expanded to accommodate bulkier items, be sure to expand the gussets if needed to avoid tearing the packaging by placing a bulkier item inside
- Locate the quick peel and seal strip at the top of the bag. Carefully peel off the protective backing to reveal the adhesive
- Press the adhesive strip firmly against the opposite side of the bag’s opening to seal it. Run your hand across the sealed edge to ensure it’s securely closed, preventing the bag from opening during transit
- Attach a shipping label, and write or print in clear text, the recipient’s address and your return address on the designated area of the bag. If using a printed label, ensure it adheres firmly to the Kraft paper surface
Tip: depending on your shipping requirements, you might need to add a "Fragile" sticker or other special handling labels. Before sending, double-check that the seal is intact and the bag is securely closed, ready for shipping
- Weigh and measure the package to determine the correct postage. This can usually be done at home with a postal scale or at the post office
- Drop it off at the post office once the package is ready. Alternatively, use a shipping centre, or schedule a pickup with your preferred shipping carrier
How do I choose the correct heavy duty mailing bag size for my parcel?

Do heavy duty mailing bags provide enough protection for heavy items?
As these heavy duty mailing bags are made from strong 70gsm paper, they are robust enough for safely sending products to your customers.
