Vaistų pakuočių kompozicinė plėvelė – tai daugiasluoksnė plėvelė, suformuota derinant pagrindines medžiagas su įvairiais plastikais, popierius, aliuminio metalo ar kitų medžiagų laminuojant, extrusion veneer, co-extrusion plastic and other process technologies. It has dustproof properties. , anti-fouling, gas barrier, 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 farmacinė pakuotė.
Tačiau, 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 (šilumos sandarinimo sluoksnis).
Common structures of pharmaceutical composite packaging include the following types:
| Tipas | Tipinė struktūra | Production Process | Savybės |
| 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 | Geras spausdinamumas, Geras standumas, gas and moisture barrier properties, degradability, ir tt. |
| 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. |
