What is the difference between Alu-Alu and Alu blister

Alu-Alu and Alu-Blister are two kinds of packaging method for food, medicine and nutrition industry especially for hard tablets and capsules. Then what is the difference between these two ways and how to choose the proper ways of packing for your own products, you may want to dig inside.

`Alu-Alu and Alu blister Variation`

Material Structure Alu-Alu is a final pack with both aluminum on top and bottom. The top layer is Blister aluminum foil (also called lidding foil) while the bottom layer is cold form aluminum foil( also called alu alu bottom foil). Alu-Blister is made of Blister aluminum foil on the top and PVC film (or PVDC coated PVC film) on the bottom.

Appreance Alu-Alu is of both side of metallic luster while Alu-Blister is with one side made of plastic so it can be more colorful or see through.

Blister Machine application Alu-Alu packing machine and Alu-Blister packing machine have different blistering structures. Alu-Alu is cold formed under the usage of the mold to directly stamp the aluminum foil into the required blister shape at room temperature. While PVC is plasticized at high temperature so that the shape required within Alu-Blister machine.

Protection Effects Alu-Alu pack has better barrier effect than Alu-Blister (usually we indicate (ALU-PVC) against water, oxygen and sunlight. In order to make up for the effects, pharmaceutical companies may choose PVDc film instead of pure PVC rigid film to achieve lower transmittance of those factors mentioned ahead.

Cost and Value Alu-Blister pack has cheaper cost than Alu-Alu pack. For normal medicines or food, Alu-Blister pack will be enough for protection. For those who are easy to absorb moisture and oxidize, Alu-Alu pack will be on top list.

Are pharmaceutical packaging material companies considered pharmaceutical companies?

In the pharmaceutical industry chain, pharmaceutical packaging material companies are often regarded as "behind-the-scenes heroes", but whether they should be classified as pharmaceutical companies has sparked widespread discussion. Pharmaceutical packaging materials play a vital role in ensuring the safety, effectiveness and quality of drugs. Therefore, more and more voices believe that these companies should be included in the category of pharmaceutical companies.

Drug packaging materials and food packaging materials: key differences in safety and performance

As consumers pay more and more attention to health and safety, packaging materials for drugs and foods have become the focus of public attention. However, although there are similarities between drug and food packaging materials in some aspects, the differences between them are crucial, especially in material selection, performance requirements and regulatory standards.

What are the Inspection Standards for Pharmaceutical Packaging Materials? —Taking Pharmaceutical Aluminum Foil as an Example

In the pharmaceutical industry, pharmaceutical packaging materials serve as important barriers to protect drug quality and ensure patient safety. The quality and performance of these materials directly affect the stability and effectiveness of drugs. With the continuous advancement of medical technology and increasing demands for drug safety from patients, stricter and more comprehensive requirements have been proposed for the inspection standards of pharmaceutical packaging materials. Pharmaceutical aluminum foil, as a high-quality material widely used in drug packaging, plays an irreplaceable role in ensuring drug quality due to its unique barrier properties, corrosion resistance, and heat-sealing performance. This article aims to explore the inspection standards of pharmaceutical packaging materials, using pharmaceutical aluminum foil as an example, and elaborates on specific requirements in terms of physical properties, microbial contamination, heat-sealing performance, and others.

Dietary Supplements vs Pharmaceuticals: Analysis of Packaging Differences

With the advancement of technology and the diversification of consumer demands, the markets for dietary supplements and pharmaceuticals are flourishing. Their packaging serves as the "first impression" of the products, carrying not only the basic functions of protecting and facilitating portability but also serving as a crucial medium for conveying product information, shaping brand image, and safeguarding consumer rights. Starting from the nature of dietary supplements and pharmaceuticals, we can delve deeper into analyzing the differences in their packaging.

Pharmaceutical Cold Aluminum Foil: The Optimal Choice for Efficient Long-Term Drug Storage

Medications are essential in our daily lives, and their quality and safety often depend on the packaging materials used. Pharmaceutical cold aluminum foil, a new type of drug packaging material, offers unique advantages for efficiently storing medications, making it an ideal choice for long-term preservation. Traditional drug packaging materials, such as plastic bottles, typically only meet basic packaging needs and pose several issues regarding drug safety and shelf life. The advent of pharmaceutical cold aluminum foil provides a new solution in the pharmaceutical packaging field, leading to widespread application. The advantages of pharmaceutical cold aluminum foil are mainly reflected in the following four aspects.

What is Pharmaceutical PVC Rigid Film?

PVC (Polyvinyl Chloride) is a synthetic plastic made from vinyl chloride monomers through polymerization reactions. It is the third largest synthetic polymer plastic in the world (after polyethylene and polypropylene) and can be traced back to the late 19th and early 20th centuries. PVC gradually became an important material in various fields. Among them, medicinal PVC hard sheets are a common pharmaceutical packaging material, with good sealing, moisture resistance, and corrosion resistance.
