The material used to package coffee
The packaging material for bagged coffee is polyester/aluminum foil/polyethylene, paper/cellophane and paper/hydrochloric acid rubber films, which mainly insulate oxygen and prevent coffee from oxidation.In addition, polyester/polyvinylidene chloride/polyethylene, polypropylene/polyvinylidene chloride/polyethylene and nylon/polyvinylidene chloride/polyethylene are not only suitable for vacuum packaging, but also for nitrogen-filled packaging.The lining material of the bag in the box is polyester/aluminum foil/polyethylene composite material. The inner polyethylene is the heat seal layer. Medium-density polyethylene should be adopted instead of low-density polyethylene.Although low density polyethylene has good heat sealing performance, it will react with coffee oil and cause coffee deterioration.After bagging the coffee, vacuum and seal it.The outer carton helps advertise the product and protects the soft packaging from damage.
