 What is Alu Alu packing?

Alu alu packing may be described as "on the outside, cold forming foil is made of aluminum, and on the inside, it is made of polymeric films. It is suitable for blister packaging to escape from moisture, oxygen, light, and chemically sensitive tablets and capsules. 

The word "ALU" indicates the aluminum material used for the bottom layer and lid of the blister pack, another side the term "ALU-ALU" indicates that both the bottom and lid layers are made of aluminum in alu alu packing so it is called Alu Alu packing.

Aluminum foil is impermeable to all gases, moisture, light, bacteria, and other substances. Due to its capacity to keep out moisture and bacteria in particular packs, it helps the medications live longer than if they were wrapped in PVC foils.

Alu Alu packing is a developed version of blister packaging in the pharmaceutical industry that provide an extra layer of protection to the product and increase the shelf life of tablets or capsules by protecting it from direct light and heat.

What is Alu Alu blister?

Tablets and capsules are two pharma doses that usually come packed in blister strips. However, injection ampoules and vials are also packed in blisters but these are very low quantities in comparison to tablets and capsules. The machine blister is the machine that allows tablets and capsules to be packed in aluminum foils from both sides. Blister uses aluminum foil from one side and another side PVC, and sometimes both sides are aluminum to wrap the tablets and capsules, which protects the tablet from moisture and light in alu alu. 

Working principle of alu alu machine

Alu alu machine is a popular packaging machine used in the pharmaceutical industry for the packing of tablets and capsules. In this machine, two servo motors are used for operating the indexing and feeding the materials to the machine. The working principle of alu alu machine follows the following principle:

  1. Feeding of material: The machine has two moving rolls that feed the aluminum foils and Aluminum films to the machine's stations.
  2. Foil Forming: The aluminum foil is supplied to forming stations where it is heated and then shaped into the required shape according to the change part shape.
  3. Filling of products: After the formation of cavities in the base foil, the machine moves to the filling stations where tablets or capsules are filled in the cavities with help of a mechanical hopper.
  4. Lidding of printed foil: After filling with tablets or capsules the base foil film moves to the lidding station where printed foil gets sealed onto the formed blister cavities, and creates a seal around each tablet or capsule on the strip.
  5. Sealing: Then the machine moves to seal stations where blister packs formated are sealed with printed foil. It is the step where it creates a tamper-evident and secure leakage-proof packaging.
  6. Cutting: Finally, alu alu packs strips are cut into individual strips, and fall into the basket from the machine.

Best ALU ALU packing machine in India?

In India, there are many good blister alu alu packing machine companies that produce high-quality machines. Elmach, Mak, and Apro Pack are some top three brands that are used in the Indian pharmaceutical industry for the packing of tablets and capsules.

Otherside, a BLK Pharmatech, Ahmedabad product, 3 Phase Double Track Alu Alu Blister Packing Machine, 220-380V is also a high capacity alu alu machine which is around 14 lakh price. 

What is the difference between Alu Alu and blister packing?

The basic difference between blister pack and alu alu packing is the material used in packaging, in Blister packing Aluminum is used on the top side of the strip and PVC on the bottom side, in blister, the product is visible in most cases. Another side, in Alu Alu packing the material used in packing, remains aluminum on both sides, however, both foils are different in thickness. There is no visibility of tablets or capsules in alu alu packing. The product remains safer in alu alu packing in comparison to blister packing. 

Aluminum-Plastic Packing is less expensive than Alu-Alu Packing. The size of Alu-Alu Pack blisters is larger than that of Aluminum-Plastic Pack blisters. As a result, more of the same product can be loaded into a single container when packed with Aluminum-Plastic Pack.

What is the advantage of Alu Alu packing?

Alu alu packing machine packing is more efficient instead of the aluminum PVC blister pack. The life of tablets and capsules increases in alu alu packing because there are no chances of entering moisture

If you have small-scale production of tablets and capsules then you should go for a cheap machine that starts from 7 lakhs.

What are the disadvantages of blister packaging?

The blister packing machine is very popular for packing tablets and capsules. Blister packing is usually known as Alu-PVC packing. In this packing, tablets are prone to get in contact with light which can reduce the life of the product. The weight of this packing is higher than alu-alu packing. The look of this strip is not so attractive in comparison to alu alu strip.
