Block bottom bag

A flat-bottom bag (also referred to as “flat bottom bag”) is a five-sided, free-standing pouch with a flat, rectangular base. It has material for greater space and strength, known as gussets, on both the left and right side of the pouch, with a fastener on top. Side gusseted bags have a single seal that spans the entire width of the bag and runs through the bottom.

The advantages of these bags are that the bags are closed from all end making it spillage proof and dust free. There is no major sealing required on the bag after filling to close it. The flat bottom allows all kinds of products for sturdy storage. It holds more weight in compare to Bottom Gusset Pouches.

Most flat bottom bags are made with kraft paper, aluminium, or LDPE. Some will combine two or more layers for added protection or aesthetic purposes. Block Bottom Bags have been a very popular style of bag for coffee packaging. Coffee roasters that want to communicate a rustic look may choose kraft paper on the outside with an aluminium foil interior, which is an effective barrier against light, moisture, and oxygen.
