Square Bottom (SOS) Bag

SOS Paper Bags with a Flat Square Bottom

SOS paper bags are handle-free paper bags designed with a flat square or rectangular base. This construction allows the bag to open into a spacious shape and stand upright more easily while products are being packed.

They are a practical option for businesses that need simple paper packaging without handles and can be produced in different sizes and paper specifications according to the intended use.

Suitable for Food, Grocery and Retail Packaging

SOS bags are commonly suited to takeaway counters, bakeries, cafés, grocery stores and other businesses packing everyday products.

The flat bottom provides useful internal space for items such as packaged food, bakery products, takeaway containers, groceries and suitable retail goods.

If handles are required, explore our Square Bottom Bag With Handle. For a narrower folded-base format, you can also view our V-Bottom Kraft Bag.

Custom Printing for Your Business

Your business name, logo or suitable artwork can be printed on the bag to create customised packaging.

For kraft paper bags, the natural paper colour should be considered when choosing artwork and print colours. Simple logos and clear brand elements can work particularly well for everyday food and retail packaging.

Paper and Size Options

The appropriate paper specification depends on the dimensions of the bag and the products it will be used to pack.

SOS bags can be produced in different widths, depths and heights, allowing the size to be selected according to your packaging requirements.

Our Paper Types and GSM Guide resources can help when selecting the appropriate specification.

Custom Sizes and Bulk Orders

Rather than using one standard size for every application, SOS paper bags can be customised according to the products your business normally packs.

For a quotation, share your required dimensions, quantity, product type, preferred paper or GSM if known and printing requirements. You can also provide your logo or artwork with the enquiry.
