What is Alu -Alu Foil

Alu - Alu Foil is used in pharmaceutical packaging for pharmaceuticals that are highly hygroscopic, light sensitive and require a very high level of barrier protection.

In Alu Alu blister packs, the lid and base are made of aluminum foil, which protects the drug from atmospheric water vapor, oxygen, and strong light.

Why Alu Alu Foil is also called Cold Formed Blister

Because in the Alu Alu foil manufacturing process, the laminate is pressed in a mold without the help of any additional heat and is completely formed by cold forming techniques.

Forming pins are used to form cavities in this film for specific tablets or capsules, which are then sealed with an aluminum lid material.

Product characteristics of alu alu foil

1,Barrier property: the current good barrier performance of pharmaceutical hard tablets, almost can be isolated from water vapor, oxygen, ultraviolet light, fragrance preservation performance is very good.
2, with the traditional PVC advantage: each blister forms an independent unit of isolation from water vapor, oxygen, ultraviolet light, take out part of the contents of a plate of tablets, there is no effect on other intact packaging of drugs in the same plate.
3,Appearance: simple, generous and beautiful, it is the ideal way for drug packaging.

Suitable scope of alu alu foil

1,Applicable to drugs with high barrier requirement.
2,Can be used for the packaging of pills, tablets, powders, suppositories, capsules and external application of drugs.
3,Applicable to cold press molding aluminum blister packing machine.

Useage of alu alu foil

Used for packaging of pharmaceuticals and food industry, packaging material for products with high barrier requirements for moisture, oxygen, light avoidance and chemicals.
For tablets, capsules, ointments and emulsions and other pharmaceutical foaming packaging.
Applicable to the foam packaging of candy, chocolate, chewing gum and other food products.

Sales of alu alu foil

Cold press forming aluminum is especially suitable for packaging medicines that are sensitive to moisture or need to be sold in hot and humid areas. By changing the mold, it can be easily designed and manufactured in a variety of shapes, and its gorgeous silver gray color adds to the attractiveness of the packaged products, which can greatly increase the sales of the products.

Typical Alu Alu Foil specifications

Alu Alu Blister Foil or CFF (Cold Formed Foil) is a film, which is a film with a multilayer structure consisting of oriented polyamide OPA (Nylon), aluminum foil and PVC film, which are bonded together using an adhesive . Typical Alu Alu Foil specifications are as follows:

OPA (Nylon) film 25 microns/adhesive/aluminum foil 45 microns/adhesive/PVC 60 microns
OPA (Nylon) film 25 microns/adhesive/aluminum foil 50 microns/adhesive/PVC 60 microns
OPA (Nylon) film 25 microns / adhesive / aluminum foil 60 microns / adhesive / PVC 60 microns

Alu Alu foil is perfect for expensive medicines

Sensitive and expensive drugs such as Cefixime, Ofloxacin, and Ciprofloxacin are packaged in aluminum-aluminum blister packs.

While aluminum-aluminum blister packs are an expensive packaging option, they are also considered the best option when they meet the API's barrier protection

1. It has high thermal stability, excellent thermoformability, high ductility, which helps to form deep brewing cavity

2. It can meet the highly sensitive requirements of drugs, and prevent moisture, oxygen, ultraviolet and thermal degradation to the greatest extent

3. It can be sealed with ordinary aluminum foil, so it is the best choice for extending the shelf life of expensive drugs and can be effectively delivered to customers.

ALU ALU Packaging VS Blister Packaging

Advantages and Disadvantages of ALU ALU Packaging And Blister Packaging
Classification	definition	advantage	shortcoming
Blister Packaging	Conventional blister packs are the most common type of pharmaceutical packaging for capsule and tablet blister packs, where the blister pack has an aluminium lid foil on one side and a PVC film (plastic) or other structure of PVC film (laminate) on the other side, Such as PVC/PVDC or PVC/PE/PVDC (three-layer composite laminate).	Compared to aluminum-aluminum blister packing, ordinary blister package cost less. Capsules or tablets are visible in it because the PVC used is mostly transparent.	Unlike regular blister packs, Alu-Alu blister packs have aluminum foil on both sides. Its WVTR (water vapor transmission rate) at 38°C/90%RH (relative humidity) is almost 0 g/m2/day, while the WVTR of standard PVC film is 3.1g/m2/day under the same atmospheric conditions .
ALU ALU Packaging	Alu Alu Blister Foil or CFF (Cold Formed Foil) is a film, which is a film with a multilayer structure consisting of oriented polyamide OPA (Nylon), aluminum foil and PVC film, which are bonded together using an adhesive . Alu - Alu Foil is used in pharmaceutical packaging for pharmaceuticals that are highly hygroscopic, light sensitive and require very high levels of barrier protection	Ordinary blister packing may not be suitable for some light sensitive medicines because the plastic side (PVC side) of the pack is transparent and the tablets/capsules are exposed to light. The permeability of PVC films generally increases with increasing temperature, resulting in a higher WVTR (water vapor transfer rate)	Cold-formed foil packs cost more than standard blister package. It is impossible to form an angle close to 90 degrees with aluminum foil, so the cavity and blister card of the resulting blister pack are larger than necessary.
