    1.What Is Alu-Alu Packaging and PVC Packaging?

    When you mention about the pharmaceutical packaging, alu-alu packaging and PVC packaging are definitely your choice. Here are the explanation of the alu-alu packaging and PVC packaging:

    Alu-Alu Packaging

    Alu-Alu-Packaging

    Alu-Alu Packaging-sourced: aluminumblisterfoil

    The alu-alu packaging refers to the packaging that both the bottom and lid are made of aluminum-based film. It uses cold forming technology, where the laminate is pressed into a mold without heating, using forming pins to create the product cavity, and then the packaging is sealed with an aluminum lid material.

    Products using alu-alu packaging are generally effervescent tablets or high-value, high-potency drugs.

    PVC Packaging

    The PVC packaging, also known as PVC-alu packaging, uses aluminum foil material on one side and transparent materials such as PVC (PVC/PVDC, PVC/PE/PVDC) on the other side to package different products. Most of the tablets and capsules such as paracetamol tablets, amoxicillin capsules, etc. are packed in this type of packaging.

    2.What Are The Application Of Alu-Alu Packaging and PVC Packaging?

    The alu-alu packaging and PVC packaging are widely used in various industries such as food, pharmaceuticals, supplements, accessories and cosmetics industry.

    Pharmaceutical Industry

    3.How To Make Alu-Alu Packaging and PVC Packaging?

    The process of making alu-alu packaging also called as the cold-forming blister formation, and the PVC packaging also called as thermoforming blister formation:

    Alu-alu Packaging: Cold-forming Blister Formation

    Alu-alu-Packaging-Coldforming-Blister-Formation

    Alu-alu Packaging: Cold-forming Blister Formation-sourced: researchgate

    Compared to the thermoforming process, the cold-forming blister formation does not use heat to shape the film. It undergoes plastic deformation by pressing the film into a mold. Therefore, this forming method is a physical and mechanical change process.

    The film cannot form an angle close to 90 degrees when it is pressed into the cavity mold. This will increase the draft angle of the bubble size, thereby increasing the production cost of cold-forming blister formation.

    The PVC Packaging: Thermoforming Blister Formation

    The-PVC-Packaging-Thermoforming-Blister-Formation

    The PVC Packaging: Thermoforming Blister Formation-sourced: researchgate

    The thermoforming blister formation is a process in which PVC film is heated to forming temperature and stretched on a mold to form. You first need to feed the PVC film into a preheating station and heat it to just above the glass transition temperature of the plastic.

    The softened plastic is later sent to a forming station. Press the mold onto the sheet. This is the most common forming method for blister packaging.

    5.What Are The Pros and Cons Of Alu-Alu Packaging and PVC Packaging?

    Alu-alu packaging and PVC packaging each have their own advantages and disadvantages, and it is not necessarily who is better between them. You can decide which packaging method is more suitable for your product by comparing their advantages and disadvantages.

    Pros Of Alu-Alu Packaging

    Strong Stability

    Strong-Stability

    Strong Stability-sourced: hanlin

    Due to the use of OPA-aluminum-PVC laminate packaging materials, it almost completely eliminates water vapor permeability and the entry of oxygen and light. It also can enhance the stability of packaged products.

    Strong Protection

    Strong-Protection

    Strong Protection-sourced: hanlin

    Due to its strong sealing, it can enhance the protection and stability of sensitive drugs, so that the active ingredients in the drugs will not be affected and destroyed. Extended shelf life of medicines. Enhanced protection against highly sensitive drugs.

    Cons Of Alu-Alu Packaging

    High Cost

    High-Cost

    High Cost-sourced: stock

    The packaging material cost of the OPA-aluminum-PVC laminate used by alu-alu packaging is higher than that of PVC, and for the same number and size of tablets or capsules, cold-formed blisters require more packaging than thermoformed blisters material.

    Complex Process

    Alu-alu-Packaging-Coldforming-Blister-Formation

    Cold-forming Blister Formation-sourced: researchgate 

    The alu-alu packaging is a cold forming process. It uses pins to press the cavity geometry into a thin sheet of aluminum. Because aluminum cannot form angles close to 90 degrees, resulting in cavities and blister cards that are larger than necessary. Therefore, the production process is more complicated.

    Takes More Time To Make

    Takes-More-Time-To-Make

    Takes More Time To Make-sourced: avantisystems

    The alu-alu packaging is slow to make and requires professional feeders. Because the board of alu-alu packaging is opaque, it increases the complexity of inspection. Therefore, it takes longer to make.

    Pros Of PVC Packaging

    Low Cost

    Low-Cost

    Low Cost-sourced: formilla

    PVC packaging uses PVC material that is easy to form and cheap. The cost of subsequent secondary packaging is also very low. Therefore, costs can be well controlled.

    Simple Process

    Low Moisture and Oxygen Resistance-sourced: versaperm

    PVC packaging has low moisture-proof and oxygen-proof properties and is not suitable for packaging such as effervescent tablets or highly active pharmaceutical packaging. Packaging cannot match CFF blister protection.

    Poor Stability

    Poor-Stability

    Poor Stability-sourced: nationofchange

    The permeability of plastic molded films for PVC packaging usually increases with temperature, making the drug susceptible to the effects of temperature, resulting in poor stability.
