Our tea tin cans are made of food-grade tinplate. Tinplate has the characteristics of corrosion resistance, high strength and good ductility. Coffee packaging containers are widely used in the industry and become a general packaging material. Good airtightness makes canned coffee last longer than bagged coffee.
Coffee iron cans are generally filled with nitrogen, and isolation from the air is good for coffee preservation, and it is not easy to spoil. After the coffee tin can is opened, it is required to be eaten within 4-5 weeks. However, the airtightness and pressure resistance of the bag are not good, and it is not easy to store and transport. The shelf life is about 1 year, and it is easy to break in transit.
People print patterns on coffee tin cans, so that the coffee cans not only play a role in food preservation, but also have a decorative appearance, which is more attractive to customers. Exquisite coffee tin cans have to go through complicated printing process to achieve the effect.
Coffee packaging iron cans made of tinplate, according to the characteristics of the contents (coffee), usually need to be coated with some kind of paint on the inner surface of the iron cans to prevent the contents from eroding the can wall and the contents from being polluted, which is conducive to long-term storage. For coffee, in order to prevent post-processing curling, exposed iron scratches and rust, it is also necessary to apply a layer of decorative paint to increase the appearance.
