Medicinal packaging composite film refers to a multi-layered film formed by combining base materials with various plastics, કાગળ, aluminum metal or other materials through lamination, 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 ફાર્માસ્યુટિકલ પેકેજિંગ.
જોકે, 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 (હીટ સીલિંગ સ્તર).
Common structures of pharmaceutical composite packaging include the following types:
| પ્રકાર | Typical Structure | Production Process | લક્ષણો |
| 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 | Good printability, good stiffness, gas and moisture barrier properties, degradability, વગેરે. |
| 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. |
