Alu Alu Foil VS Plain Foil

Cold-formed aluminum foil and ordinary aluminum foil are both packaging foil materials with a relatively thick foil thickness obtained after calendering of aluminum alloy. They have many similarities in physical properties, but also have many differences.

The main difference between cold-formed medicinal foil and ordinary aluminum foil lies in their composition, manufacturing process and application.

Cold aluminum foil and plain foil have different compositions

Cold-formed medicinal foil:

Alu alu foil is a multi-layer structure that usually consists of three main materials: alyuminiy folga, polimer plyonka (PVX yoki PVDC), and usually a layer of nylon (OPA). The layers are laminated together to achieve excellent barrier properties. Aluminum acts as the main barrier layer, while PVC provides strength and flexibility, va neylon tarkibini kuchaytiradi.

Oddiy alyuminiy folga
U tarkibiga kiradi 100% alyuminiy, ba'zan ular mo'ljallangan foydalanishga qarab yupqa polimer yoki moylash vositasi bilan qoplangan. Oddiy folga qo'shimcha laminatsiya va oddiy tuzilishga ega emas.

Alu Alu Foll Vs Oddiy folga ishlab chiqarish jarayoni

Sovuq shakllangan farmatsevtika folga
Sovuq shakllantirish jarayonidan foydalanib, ko'p qavatli laminat va kerakli shaklga bosilgan yoki bosilgan holda (blister) Isitishsiz. Yagona to'siqni himoya qilish va shakllanishini ta'minlash uchun ixtisoslashtirilgan uskunalar va aniq laminatsiya talab qilinadi.
Oddiy alyumin folga:
Alyuminiy choyshablar ingichka varaqlarga o'ralgan jarayon orqali ishlab chiqarilgan. Bu laminatsiyani yoki sovuq hosil qilishni o'z ichiga olmaydi. Sovuq shakllangan farmatsevtika folga bilan taqqoslaganda ishlab chiqarish jarayoni sodda.

Turli xil to'siq xususiyatlari

Sovuq shakllangan farmatsevtika folga: Due to its multi-layer structure, beradi 100% barrier to moisture, kislorod va yorug'lik, making it suitable for highly sensitive drugs (e.g. tablets or capsules that degrade in moisture or light). Provides excellent durability and protection to meet long shelf life requirements.
Oddiy alyumin folga: It provides a good but not absolute barrier to moisture, yorug'lik va gazlar. Pinholes may form during the manufacturing process, reducing its effectiveness as a complete barrier.

Different applications

Sovuq shakllangan farmatsevtika folga: Used in blister packaging in the pharmaceutical industry to package sensitive drugs. Preferred for packaging high-value and highly reactive drugs as it ensures maximum protection.
Oddiy alyuminiy folga: Widely used in household applications (E.G., oziq-ovqat qadoqlash, pishirish, va pishirish). Also used for industrial and commercial purposes such as insulation, but it is not designed for sensitive pharmaceuticals.

Thickness and strength

Cold-formed pharmaceutical foil: Thicker due to its multi-layer structure (typical aluminum thickness is about 20-25 mkm, plus polymer and nylon layers). This makes it stronger and more durable than ordinary foil.
Oddiy alyuminiy folga:
Usually thinner, dan tortib 6 µm to 20 mkm, depending on grade and use. It is more flexible, but has poorer puncture and tear resistance.

Difference in cost

Cold-formed pharmaceutical foil: More expensive due to its complex structure, advanced manufacturing process, and specialized applications.
Oddiy alyuminiy folga: Relatively cheap and widely available due to its simpler composition and production process.

Cold-formed pharmaceutical foil is designed for sensitive pharmaceutical packaging with high barrier requirements and long-term stability, while regular aluminum foil is a versatile, low-cost material suitable for general-purpose applications where barrier properties are less important.
