Aluminum collapsible tubes are a versatile and widely-used packaging material. This article explores the history and evolution of these tubes, delving into the production process and offering insights for industry professionals. Junsam produce aluminum collapsible tubes from pure aluminum (99.7% purity), making them ideal for packaging a wide range of products, including medications, cosmetics, toothpaste, pigments, greases, hair dyes, condiments, and adhesives. The collapsible nature of these tubes prevents air ingress, thereby protecting the contents from oxidation and contamination, and extending shelf life.
The Evolution and Current State of Aluminum Collapsible Tubes
The most common types of aluminum tubes are used in pharmaceuticals and beauty products. They can be categorized into collapsible aluminum tubes and rigid aluminum cans. Collapsible tubes, often referred to simply as “collapsible tubes,” are primarily used for packaging ointments, art pigments, cosmetics, sealants, toothpaste, shoe polish, adhesives, hair dye, ketchup, chocolate sauce, instant glue, and other paste-like products. In contrast, rigid aluminum cans, which are not collapsible, are used for effervescent tablets, capsules, sprays, and other dosage forms.
Packaging tubes can be classified into three categories: metal tubes, plastic tubes, and laminated tubes. Among these, metal tubes have the longest history. The modern aluminum tube, first developed by the Swiss in 1913, became widely adopted in 1937. Aluminum tubes are seamless, allowing for perfect printing on their round surfaces. However, a common issue is that the shoulder area can be difficult to fully empty, often leaving some residue.
The Three Generations of Aluminum Tube Development
First Generation: Lead-Tin Tubes
In the early 1840s, the United States developed lead tubes, later mass-producing lead and tin tubes for various products by the 1870s. However, due to the toxicity of lead and the scarcity of tin, these tubes were eventually phased out.
Second Generation: Aluminum Tubes
With the advancement of electrolytic aluminum technology and the material’s non-toxic nature, aluminum tubes became popular. However, early aluminum tubes had poor sealing properties, which sometimes led to chemical reactions between the tube and its contents, affecting product safety.
Third Generation: Improved Aluminum Tubes
The latest generation of aluminum tubes features significant improvements, such as a thin top seal and a sealing coating at the tail. These enhancements prevent air from contacting the contents, reducing the risk of leakage and drying. The interior wall coating also prevents direct contact between the product and the aluminum, ensuring the product’s efficacy and safety. Modern tubes also offer multi-color printing and additional features like plastic cleaning heads and specialized nozzles for eye ointments, enhancing cleanliness and medication safety. Despite the initial monopolization of production equipment by a few foreign companies, domestic production began to flourish with China’s reform and opening-up, leading to widespread adoption of the third-generation aluminum tubes.
