Functional classification

(1) enhanced composite packaging.

(2) high impermeability composite packaging (gas, water and oil resistance).

(3) anti-corrosion type (corrosion and rust prevention) composite packaging.

(4) anti-electromagnetic field (dry worry) composite packaging.

(5) anti-static composite packaging.

Be careful with the classification by application: ordinary, boiled and steamed. Ordinary packaging means that the contents are put into the package at room temperature; boiled packaging usually requires the packaging material to resist boiling at 99 degrees for 30 minutes; steaming is divided into two different applications: 121 degrees and 135 degrees.

Select by printing method: surface printing, lithography without lamination, lithography lamination. Surface printing refers to the ink printed on the outer surface of the package; inside printing refers to the pattern printed on the inside of the package, which may be in contact with the packaged material; inside printing composite refers to the outer layer of composite packaging using inside printing.
