The Classic Coffee & Dry Goods Bag
The side gusset bag is one of the most recognisable packaging formats in the specialty coffee and premium dry goods industry. Its flat front and back panels combined with folded side gussets create a sleek, pillow-like appearance when empty — and a sturdy, block-bottom look when filled.
The four wide seal panels give brand designers ample space to work with, making this format ideal for brands that want to communicate premium quality at retail. Pair it with a tin tie or zipper for consumer convenience, and a one-way degassing valve for freshly roasted coffee.
