The four-sided sealed bag (side gusset) has the advantage of high strength and suitable fill volume. Side gusset bags are recommended for weights ranging from 5 to 20 kilograms. The four longitudinal seams act like strong straps, increasing the bag’s durability along its length or height, and a notable feature of this packaging is its resistance to tearing upon impact.
Another advantage of the four-sided sealed bag is the ample space it provides for printing and advertising. Despite lacking a bottom gusset, these bags have relatively good stability and are often used for packaging coffee powder, pet food, cat litter, bodybuilding supplements, and other heavy and bulky items.
The single-layer construction of these bags simplifies their design, printing process, and bag-making, making them less expensive than other bags such as pouch boxes and stand-up pouches. Thus, they are a suitable choice for affordable and economical products.
