Cấu trúc của vật liệu composite bao bì dược phẩm là gì?

Màng composite bao bì dược phẩm dùng để chỉ màng nhiều lớp được hình thành bằng cách kết hợp vật liệu cơ bản với nhiều loại nhựa khác nhau, giấy, kim loại nhôm hoặc các vật liệu khác thông qua cán màng, extrusion veneer, co-extrusion plastic and other process technologies. It has dustproof properties. , anti-fouling, rào cản khí, 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 bao bì dược phẩm.

Tuy nhiên, 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 (lớp niêm phong nhiệt).

Common structures of pharmaceutical composite packaging include the following types:

Loại hình	Cấu trúc điển hình	Production Process	Đặc trưng
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	Khả năng in tốt, Độ cứng tốt, gas and moisture barrier properties, degradability, vân vân.
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.
