La pel·lícula composta d'embalatge medicinal es refereix a una pel·lícula de diverses capes formada combinant materials base amb diversos plàstics, paper, metall d'alumini o altres materials mitjançant laminació, extrusion veneer, co-extrusion plastic and other process technologies. It has dustproof properties. , anti-fouling, barrera de gas, fragrance maintenance, UV protection and other functions.
No packaging material used alone can achieve the above functions, but after compounding, it can basically meet various requirements for envasos farmacèutics.
No obstant això, composite membranes also have the disadvantages of being difficult to recycle and easily causing pollution.
The composite film is expressed as surface layer/printing layer/adhesive layer/aluminum foil/adhesive inner layer (capa de segellat tèrmic).
Common structures of pharmaceutical composite packaging include the following types:
| Tipus | Estructura típica | Production Process | Característiques |
| 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 | Bona imprimibilitat, Bona rigidesa, gas and moisture barrier properties, degradability, etc. |
| 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. |
