(1)Advantages

①The metal packaging material has an unique luster, which is convenient for printing and decoration, and makes the appearance of the product beautiful and gorgeous. In addition, metal foil and gold-plated film are ideal trademark materials.

②The metal packaging material has high strength. Therefore, the wall thickness of the packaging container can be very thin, so that the weight is light, the strength is high, and it is not easy to be damaged.
for storage and transportation, it has good protection for commodities.

③ Metal packaging materials are rich in resources and have good processing performance. The recoverable amount of steel on the earth is 1294 × 10 ° t, ranking first, followed by aluminum, which is 68 × 10 ° t. Metal packaging materials can be processed with different methods to produce containers of different shapes and sizes.

④Metal packaging materials have good comprehensive protection performance. Metals have low permeability to water and gas, and are opaque, which can effectively avoid harmful effects such as ultraviolet rays. It has good comprehensive performance and can maintain the quality of the goods for a long time.Some packages are valid for up to two years.

⑤The production of metal cans has a long history and the process is relatively mature. Now it has automated production and high production efficiency.

2) Disadvantages

①Pb and as in metals and solder easily penetrate into food and contaminate food; in addition, metal ions will also affect the flavor of food.

②When the metal container uses phenolic resin as the inner wall coating, if the processing technology is improper, it will also affect the quality of the food.

Main properties of several major types of metal packaging materials

(1)Protection function. The protection function of the packaging is the most basic and the most important function. It should protect the product from damage and loss. In the circulation process of goods, the factors that cause harm to them are: environmental conditions, such as temperature, humidity, gas, radiation, microbial insects, rodents, etc., Which may damage the packaging and harm the product; human factors, the goods are transported, during storage, due to careless or improper operation, the goods are damaged by shock, vibration, or fall, or they are crushed due to too many stacked layers. Therefore, according to factors such as the shape, characteristics, transportation environment, sales environment and other factors of different products, the most appropriate materials, reasonable design of packaging containers and technologies should be given to the packaging to provide sufficient protection functions to protect the safety of the products inside, and the special use of dangerous goods packaging, pay attention to prevent its damage to the surrounding environment and people and creatures.

(2) Convenience function modern product packaging can bring many conveniences to people, which plays an important role in improving work efficiency and quality of life. The convenient function of packaging should be reflected in the following aspects.

①Convenient production for mass-produced products, packaging should meet the needs of mechanization, specialization and automation of production enterprises, taking into account resource capacity and production costs, and increase labor productivity as much as possible.

②Convenient storage and transportation for the quality and volume (size, shape, etc.) Of each packaging container, the convenient loading and unloading of various transportation vehicles should be considered for stacking; also consider that the quality of manual loading and unloading of goods generally does not exceed 40% of the worker’s weight (limited to about 20kg), etc .; At the same time, it should also consider the storage and stacking method of storage and transportation into warehouses, shops, and residences during circulation indoor decoration and storage during the process.

③ Convenient use of suitable packaging should make consumers feel convenient when opening, using, storing and storing. Such as carton sealed with adhesive tape, cans, spray packaging, portable packaging, etc., In a concise language or icon, to explain the precautions and methods of use to consumers to facilitate the use.

④Convenient handling means that some packages have the function of repeated use.
