In the pharmaceutical industry, beyond their packaging appearance, aluminum collapsible tubes offer many benefits to both consumers and manufacturers.

What are the advantages of the aluminum collapsible tube for pharmaceutical ointment?

There are many packaging containers in the pharmaceutical industry. Why does ointment like to use aluminum collapsible tubes, not plastic collapsible tubes?

The collapsible aluminum tube is a container that has been softened and used for packaging creams, ointments and other products, it is one of the most important pharmaceutical packaging containers. Aluminum collapsible tubes can be used as the first choice of pharmaceutical ointment packaging, which can not be separated from their own superiority.

As a packaging material and container in direct contact with drugs, the material must be safe and stable. Metal is stable, but aluminum is much more stable and safe. In pharmaceutical packaging, the quality and safety of aluminum tubes, their performance during use, and their compatibility with the drug have a significant impact on the quality of the drug itself.

There are too many advantages of aluminum tubes: Eco-friendly / 100% recyclable / Lightweight / Unbreakable / Non-reactive / Corrosion-resistant / Longer shelf life for products. It is much better than plastic tubes as it’s 100% recyclable.

BENEFITS OF ALUMINUM TUBE PACKAGING?

1. Recycled Infinitely

2. Product protection

3. Shipping

4. Customizing

5. Sizing

6. Applicators

7. Complete product use

8. Luxurious feeling

1 . Good processing performance, strong plasticity.

The density of pure aluminum is only 2.7 grams per cubic centimeter, making it a light metal that can be used in a variety of casting methods and processing techniques, and is easy to shape. In making aluminum tubes, the aluminum manufacturing process is simple and easy, and the finished products are less prone to breakage, which can greatly reduce processing costs and promote energy savings. Also, it can produce tubes of different sizes, diameters, and lengths, with different shoulders and nozzles.

2. Corrosion resistance, good sealing

The surface of aluminum and its alloys is easy to form a dense oxide protective film, which can effectively isolate water, oxygen, etc., and prevent product corrosion during circulation and use. And with the end latex of the empty aluminum hose has good sealing characteristics and more adequate sealing protection for the drugs contained inside.

3. Good thermal conductivity and good ductility.

Aluminum is a good conductor of heat, its thermal conductivity is three times greater than iron, and its electrical conductivity is second only to copper, and silver, when the cream in the hot filling, more conducive to facilitating rapid cooling heat dissipation, effectively ensure the stability of the cream.

4. Good shading and reflectivity

The polished surface of aluminum reflects more than 80% of white light. The higher the purity, the higher the reflectivity, especially for infrared, ultraviolet, thermal radiation, and other good reflective properties, which can be used for storage on a variety of occasions, saving more storage and circulation costs, suitable for long-term display of the counter, increasing the chance of product exposure.

5. Non-magnetic, impact does not produce sparks.

This feature provides strong guarantees for safe production management and high security for market circulation.

6. High barrier performance.

Compared with other non-aluminum materials, aluminum has excellent moisture and gas barrier properties. Generally speaking, aluminum foil thicker than 0.01 mm has good moisture-barrier performance. Greater than 0.015MM has gas impermeability. The increase in thickness can effectively improve the barrier performance.

7. Good and clear printing

The smooth surface of the aluminum tube is ideal for offset printing, but not for screen printing, hot stamping, silver stamping, and other printing methods. Offset printing involves placing all the text artwork on one page and then printing it onto the aluminum tube, so the overall text is clear and easy to read, which is also very important for pharmaceuticals.

What’s the popular volume for pharmaceutical packaging aluminum tubes?

Any volume is fine, a wide range. The collapsible tube is flexible and squeezable.

The most popular dimension for eye ointment tubes is 13.5mm, like 13.5mm for 5g

Also, 16*100mm for 10g, 19*105mm for 15g, 22*110mm for 20g, 22*130mm for 30g, 25*115mm for 30g, 25*145mm for 50g, 32*175mm for 100g.

What’s the printing for the aluminum medical tube?

There is offset printing and silver printing on aluminum tubes, with a glossy or matte finish. Also, the paper sticker applied to the flexible aluminum tube is a good method to expand clients’ brands & logos for some clients.  Paper stickers can be hot-stamped, silver-stamped, glossy, or matte.

What quality problems may aluminum collapsible tubes have?

There Are Some Critical Defects:

Different Items Were Mixed.

Material Is Different From Specification;

No End Latex Application When Needed;

Printing With Text, Art Wrong, or Missing or Displaced, Omit The Text;

The Low Resistance Of Paint In The Printing

No Internal Coating Application;

How to test pharmaceutical aluminum tubes?

Pharmaceutical aluminum tubes are used to fill eye ointments and ointments that come into direct contact with the eyes, skin, etc., so their safety and hygiene standards must be held to high standards. Throughout the entire production process, which quality testing items must be paid special attention to? How should enterprises implement the quality inspection of ointment aluminum tubes?

The purity of the aluminum sheet: it affects the ductility and airtightness of the aluminum tube. The low purity of the aluminum sheet indicates higher impurity levels, which can easily lead to a decline in stretchability and are not conducive to stamping. Such a sheet of aluminum, extruded by the punching machine, is very easy to produce burrs or pits on the wall of the tube. After comparing aluminum sheets from more than ten domestic and foreign manufacturers, we finally chose the 99.7% pure aluminum sheet, which meets the strict precision requirements of high-speed punching machines, and the produced pharmaceutical aluminum hose has good ductility and strong airtightness.

Quality inspection of the inner coating: As the inner wall of the soft aluminum tube will be in direct contact with the ointment, in order to prevent the aluminum from contaminating the ointment or the chemical properties of the strong ointment corrosion hose must be coated with a protective film on the inner wall of the aluminum tube to isolate the two. Obviously, the quality of the inner coating of the soft aluminum tube will directly affect the isolation effect, such as if the inner coating is not continuous, uneven, has bubbles, is too thin, easy to fall off, the inner coating paint performance is not stable, and the existence of these problems will bring great potential problems to the final product. The internal coating machine can apply three times to the inside of the aluminum hose, from the top of the tube, the shoulder, and the body to the end of the tube, to ensure the formation of a uniform, continuous, thin, and moderate-thickness protective film. The inner coating of the pharmaceutical aluminum hose is made of FDA-approved material, which has good leveling, stability, and anti-aging properties to ensure the inner coating’s performance.

Test the continuity and chemical stability of the inner coating: The testing procedure for the inner coating’s quality is complex and requires professional instruments. – Continuity of inner coating: below 20mA is regarded as qualified. Using the internal coating continuity tester, the coated aluminum hose is filled with the test solution of copper sulfate, a sliding electrode is immersed in the test solution, and the soft aluminum tube itself is in contact with a base electrode with a V-slot, then a DC voltage of 50.5V is applied between the sliding electrode and the aluminum tube, and the current flowed is proportional to the surface area of the aluminum collapsible tube not covered by the internal coating. If the coating is discontinuous, there will also be black copper deposition, indicating the location of the leak. The national standard stipulates that the leakage current shall not exceed 40 mA, and the measured value is generally kept at 20 mA or less. – Chemical stability of the inner coating: cut the aluminum tube body longitudinally and level it, lightly rub the inner coating with skimmed cotton dipped in acetone 30 times, and observe whether the coating comes off on the skimmed cotton.

Flexibility and adhesion of the inner coating: The aluminum tube body is squeezed by the inner-coating flexibility and adhesion test device, then stretched; the inner coating should not fall off.
