The composite film is expressed as surface layer/printing layer/adhesive layer/aluminum foil/adhesive inner layer (tepelně těsnící vrstva).
Common structures of pharmaceutical composite packaging include the following types:
| Typ | Typická struktura | Production Process | Vlastnosti |
| Ordinary composite membrane | PET/DLAL/PE
PET/AD/PE/AL/DL/PE |
Dry compounding method or extrusion first and then dry compounding method | Good printing adaptability, gas and moisture barrier properties. |
| Easy-to-tear strip packaging | PT/AD/PE/ALAD/PE | Extrusion compounding | Good printing adaptability, gas and moisture barrier properties. |
| Paper aluminum plastic packaging | Paper/PE/AL/ ADPE | Extrusion compounding | Dobrá potiskovatelnost, dobrá tuhost, gas and moisture barrier properties, degradability, atd. |
| High temperature cooking film | BOPA/CPP or PET/CPP
PET/ALCPPor PET/ALNY/CPP |
Dry compounding | It can basically kill all bacteria in the package. It can be placed at room temperature without cold installation. It has good gas and moisture barrier properties, is resistant to high temperatures, and has good printability. |
