General roasted and ground coffee are packed in vacuum with good airtightness, both bagged and canned, and the latest ones are packed in boxes. Ordinary coffee also uses inflatable packaging technology.
Inflatable packaging technology is vacuum before sealing and filled with other inert gases, coffee inflatable packaging is often filled with nitrogen or carbon dioxide; vacuum packaging technology is coffee bagged, vacuum and sealed. The main purpose of the above two packaging technologies is to remove oxygen. Therefore, the packaging materials used must have sufficient air tightness and heat sealing performance. Vacuum and inflatable packaging technology can effectively prevent coffee from moisture and oxidation, and the fragrance preservation effect is also very good.
At present, the retail packaging of coffee is generally made of composite materials, and it is carried out on the vertical molding-filling-sealing packaging machine. Before sealing, vacuum and then filled with nitrogen, the fragrance preservation effect is better. The packing is in the form of pillow, three-sided sealing or four-sided sealing. Instant coffee is also widely used paper / aluminum foil / polyethylene flexible packaging structure, enough to achieve moisture-proof and oxygen insulation effect. The remaining space in the pouch is limited, and the internal oxidation problem can be ignored.
