Rational analysis of the advantages and disadvantages of metal packaging

January 02, 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 performance Metal packaging materials have very low (nearly zero) permeability to gases, water, and water vapor, are good in fragrance, and are completely opaque and effective. 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 advantageous for 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) With special metallic luster, good surface decoration, special metallic sheen, and exquisite decorating 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 The metal packaging containers and internal paints generally meet the requirements of hygienic safety, and the products that are packaged are convenient to carry and use (usually equipped with easy-open devices such as pull-tabs for cans, etc.), and can be adapted Different climatic conditions. And waste disposal is good, can be recycled and used.

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