Rational analysis of the advantages and disadvantages of metal packaging

January 25, 2023

As one of the four major Packaging materials, Metal Packaging materials occupy an important position in modern packaging materials. In general, metal packaging materials have the following advantages.

(1) Excellent barrier properties and excellent comprehensive protective properties Metal packaging materials have extremely low (nearly zero) permeability to gases, water and water vapor, good fragrance protection, and are completely opaque and can effectively Avoid the harmful effects of ultraviolet rays; its gas barrier properties, moisture resistance, shading, and fragrance protection far exceed those of other types of packaging materials such as plastics, paper, and so on. Therefore, the metal package can provide excellent protection properties for the contents, which is conducive to maintaining the quality of the products for a long time.

(2) Good mechanical properties, processability, and high strength metal packaging materials have good ductility and high strength, can be stamped, rolled, stretched, welded, etc., can be made into thin-walled, The packaging container with high compressive strength and not easily damaged can also be combined with other materials to form a composite packaging material with excellent comprehensive performance.

(3) It has special metallic luster and good surface decoration. The special metallic luster combined with exquisite decoration and printing can make the goods look wealthy and gorgeous, beautiful and marketable, and at the same time can increase the value of goods.

(4) Convenient and hygienic metal packaging containers and internal paints generally meet the requirements of hygienic safety, and it is convenient to carry and use the packaged products (generally equipped with easy-opening devices, such as pull-tab cans, etc.), able to adapt Different climatic conditions. And waste disposal is good, can be recycled and used.

Although metal packaging materials have many advantages, they also have shortcomings, including: poor chemical stability, especially steel materials are easily rusted, generally should be coated with rust-proof substances; weak acid and alkali resistance, and packaging of acidic substances ( Especially when food), metal ions will precipitate and affect the quality of the product, and generally require isolation and protection of the inner coating; the price of metal packaging materials is higher than other packaging materials, and the overall packaging cost is also higher.
