| 1 | Match paper type to the job | Kraft paper is commonly chosen for its natural appearance and general-purpose strength. White or coated paper provides a smoother surface for detailed printing. Recycled-content paper is another option; its appearance and performance vary by grade. | Retail shopping, takeaway, gifts, and promotional packaging | Consider the required print finish, appearance, contents, and whether recycled content or a particular paper specification is needed. |
| 2 | Select an appropriate paper weight | Paper weight is often specified in grams per square metre (gsm). As a broad starting point, lighter bags may use roughly 70–100 gsm paper, while heavier-duty bags may use around 120 gsm or more. These are not guaranteed load ratings. | Choosing a starting specification for samples and testing | Bag size, paper grade, seam design, handle attachment, humidity, and load all affect performance. Test a finished bag with the intended contents. |
| 3 | Choose handles for comfort and load | Twisted-paper handles offer a paper-based option for many retail bags. Flat-paper handles sit comfortably in the hand. Rope handles can provide a more substantial feel, while die-cut handles eliminate a separate handle but require a reinforced or suitably designed top. | Retail bags, gift bags, and bags carried by hand | Check handle strength, attachment area, grip comfort, and whether the handle material matches the intended bag design. |
| 4 | Use a base construction suited to the contents | A flat-bottom or block-bottom bag can stand upright and accommodate boxed or bulky products. A simple flat bag may suit lightweight, flat items. A bottom insert can help spread weight across the base. | Groceries, takeaway containers, books, and boxed goods | Check that the base dimensions fit the product and that the bottom seams and any insert support the intended load. |
| 5 | Size the gusset and bag dimensions carefully | Side gussets expand to provide more capacity; the bottom gusset or base depth determines how well the bag accommodates three-dimensional items. A closer fit can reduce excess material and help limit product movement. | Products with varying widths or depths | Measure the product, allow room for easy packing, and account for closures or protective packaging. |
| 6 | Consider coatings only when needed | Coatings or laminations can improve surface durability and resistance to moisture or scuffing, but they may affect recyclability depending on the materials and local recycling facilities. Treated paper should not automatically be considered waterproof. | Printed bags or applications involving light surface exposure | Confirm the required level of protection and check local recycling guidance for the complete bag, including coatings, handles, and attachments. |
| 7 | Test the complete bag before ordering | A finished sample brings together the paper, size, seams, base, handle, and printing. Testing with representative contents is more informative than relying on paper weight alone. | New bag designs, heavy products, and repeat production | Check loaded carrying, handle comfort, seam integrity, base stability, packing speed, and appearance under expected storage conditions. |
