Lehua side gusset coffee pouch:
Benefits for Consumers: Besides freshness preservation, side gusset pouches are often easier to store than rigid containers due to their flexible design. The gussets also make it convenient to pour the coffee without spilling.
Degas Valve: Some side gusset pouches come with a one-way degassing valve. This valve allows carbon dioxide to escape from freshly roasted coffee beans while preventing air from entering the pouch, which can spoil the coffee.
Sustainability: While traditionally made from foil or laminated materials, there are now also side gusset pouches made from recyclable or compostable materials.
