Sealing & Handle:
Although the package of coffee in the box is lighter than metal can, the cost is lower, and it is convenient for stacking and display during the exhibition, the packaging equipment of the bag in the box is larger than that of the canning equipment, and the operation process is more complicated.On the mechanized packaging, the efficiency of producing the coffee in the box is only 60 boxes/min, while the efficiency of producing coffee cans by mechanization can be up to hundreds of cans per minute.In addition, the coffee in the box bag, opened after use, not easy to cover tightly, will accelerate the deterioration of coffee.
At present, the retail packaging of coffee generally USES composite materials, and in the vertical molding of a filling and packing machine.Before sealing, it was filled with nitrogen after vacuumization.Packing in the form of pillow, three - side sealing or four - side sealing.Instant coffee is also widely used in paper/aluminum foil/polyethylene flexible packaging structure, enough to resist moisture and oxygen insulation.There is limited space left in the pouch, and the internal oxidation problem is negligible.
