Extrusion film accumulation layer composite package.      

Multi-layer co-extrusion (by more than two extrusion head) composite soft package.     

Hot melt coated composite soft package.     

Solvent-free (i.e., solid binder) composite soft package.     

Physical vapor deposition composite soft package.      

Compounding type soft package.      

Combination of the aforementioned methods of composite soft package, etc.

Second, according to the classification of composite material      

Paper and paper.      

Paper and metal foil.      

Paper and plastic film.     

Plastic film with plastic film.   

Plastic film with metal foil.     

Plastic film with metal foil.   

Plastic film with substrate material.   

Plastic film with inorganic compound film.   

Plastic film and organic compound film.      

Amorphous plastic film with plastic film.      

Substrate material with nano-like super-particle composite   

Substrate material coated or impregnated with special additives.

Partial lamination, e.g. only in the packaging closure area or imparting certain functions.  

Laminate sheet or laminate bag, where special features are combined in one place to perform an overall function.      

Gradual lamination (or non-uniform lamination, as needed in the direction of the thickness of the laminated booklet (or length, changing the concentration, component or thickness of the added material).     

 Special lamination, such as lamination by mesh pattern, etc.

Third, according to the composite function classification      

Increase the type of composite packaging.     

Highly permeable composite packaging (gas, water and oil resistance).

Fourth, according to the application classification: ordinary, boiling, steaming.

Ordinary packaging refers to the contents into the package at room temperature. Boiling packaging usually requires packaging materials at 90 degrees boiling water for 30 minutes. Steaming is divided into 121 degrees and 135 degrees two different applications.      

Fifth, according to the printing method: surface printing, printing not composite, printing composite.

Surface printing refers to the ink printed on the outside surface of the package. Inside printing refers to the pattern printed on the inside of the package, may be in contact with the packaging. Lile printing composite refers to the outer layer of composite packaging using lile printing.
