When you pick up your favorite hand cream or lotion from the shelf, have you ever wondered about the magic happening inside the sleek hand cream aluminum tubes that keeps your product safe and intact? The secret lies in a crucial process known as internal lining or internal lacquering. In this article, let’s look at the fascinating world of aluminum collapsible tubes, exploring the features of the lacquer and uncovering its essential benefits.
The Marvel of Internal Lacquering
At the heart of the production of aluminum collapsible tubes lies a meticulous process – the application of a layer of lacquer on the inner wall of the tube. This internal lining, or internal lacquering, is a vital step that transforms a simple aluminum tube into a robust guardian for your hand cream or lotion.
Features of the Lacquer
The lacquer used in the internal lining process is no ordinary coating. The material used for coating can be either of vinyl, epoxy or phenolic resins. It is a dispersion of fine spherical particles of a metal adhesive thermoplastic resin. This coating is applied to the inside wall surface of the collapsible tube and then heated to fuse the fine spherical particles, forming a metal-adhesive thermoplastic resin layer. This layer acts as a barrier between the exposed aluminum and the contents, preventing any potential interactions that could compromise the product. The quality of the lacquer can be determined by factors such as its ability to resist corrosion, maintain stability under varying temperatures, and provide an effective barrier against external elements.
Advantages of Internal Lining
1. Barrier Protection: One of the primary advantages of internal lacquering is its ability to provide a barrier between the exposed aluminum and the contents. This barrier protection is crucial for products sensitive to metal.
2. Corrosion-Free Packaging: Collapsible aluminum tubes, when internally lined with the appropriate lacquer, become a stable and corrosion-free packaging solution. This is especially important for pharmaceuticals and cosmetics, where maintaining the purity of the product is paramount. (Reference: cosmetic packaging tubes, pharmaceutical packaging tubes)
3. Impermeability to Moisture, Gas, Odor, and Light: The lacquer, combined with the inherent properties of aluminum, makes the tube impermeable to moisture, gas, odor, and light.
4. Preservation of Product Freshness: Internal lacquering minimizes the risk of air entering the pack, preventing reactions with the product or causing it to dry out.
5. Chemical Reaction Prevention: In some cases, the internal coating becomes necessary to prevent chemical reactions between the product and the metal. The inert internal lacquer acts as a shield, ensuring that the hand cream or lotion retains its original properties.
What If There Is No Internal Lacquer in Hand Cream Aluminum Tubes
Imagine a world where the hand cream aluminum tubes protecting your hand cream are devoid of internal lacquer. In such a scenario, the risk of chemical reactions, contamination, and product deterioration would skyrocket. The absence of a protective barrier would leave your favorite creams vulnerable to the external environment, jeopardizing their quality and effectiveness.
In the world of packaging, it’s often the unseen processes that play a pivotal role in ensuring product quality. Internal lining in hand cream aluminum tubes is a prime example of this. Understanding the significance of these intricate processes allows us to appreciate the efforts made to deliver products that are not only effective but also safe and reliable.
