Macfarlane Packaging can supply a large range of bags for a variety of applications. We can offer many different sizes, shapes, and styles of bags to suit business needs.

Bag dimensions are listed width x height or, if gusseted, closed width x open width x height.


To calculate the size of the bag you require, the following calculation works for all bag types, hoods and liners:


  • For a relatively flat item, calculate the face width of the bag. Measure the width of your item (A) and add a 50mm allowance to it. An odd load or shape may need 100mm tolerance.

  • For a larger, bulkier item the bag needs to open wider. The measurement is the width of your item (A), plus the depth of your item (B), plus 100mm tolerance. An odd load or shape may need 150mm tolerance.

  • The length of bag needed is calculated by measuring the height of your item (C), plus the measurement of the depth (B), plus a 150mm tolerance. You may wish to add extra length if the bag is to be tied off or dropped over the sides of a container.
The type of packaging bag you need will depend on what you’ll be using it for. There are a few things you should consider when choosing the bags you need:

  • Are your products lightweight or heavy?
  • What will you be using your bag for? E.g. retail, food, waste disposal or posting products?
  • If you’re using bags for posting products, do they need to meet Royal Mail parcel or envelope sizes?
  • Do you need to buy bags in high volumes?


For example, if you’re shipping lightweight or letterbox size products like clothes, you will probably want a mailing bag. Whereas if you need a bag to store products and seal them away, a grip seal bag will work well.
