The Art of Sealing for Metal Tube Packaging

  • Reading time:3 mins read

Aluminum collapsible tubes have become indispensable in packaging viscous paste products, such as glue, lubricant grease, toothpaste, cream, and ointment. These tubes not only provide a convenient and user-friendly container for various products but also ensure the preservation of their quality. One crucial step in the metal tube packaging process is the sealing of these metal tubes by folding. That is, the far end of aluminum tubes is to be folded several times after the contents have been filled. Now, let’s explore why tube sealing is essential and look at three common sealing techniques: double fold, single fold turn back, and saddle fold methods.

Importance of Tube Sealing

1. Product Freshness and Shelf Life

Properly sealed tubes act as a barrier against external elements, such as air and moisture, preventing the product from drying out or becoming contaminated. This ensures the freshness and extends the shelf life of the enclosed paste.

2. Leak Prevention

In the process of metal tube packaging, tube sealing is a critical aspect in preventing leaks. A securely sealed tube guarantees that the contents remain contained within the packaging, avoiding mess and potential damage to other items during transportation or storage.

3. Brand Image and Consumer Trust

The way a product is packaged reflects directly on the brand. A well-sealed tube not only safeguards the product but also enhances the overall perception of quality. This instills trust in consumers, as they associate a securely sealed package with a brand that values the integrity of its products.

Types of Tube Sealing

1. Double Fold: Once the content has been filled in the tube, the open end of the tube is to be sealed. Double fold means the tube end is to be flattened and then folded twice, creating ideal protection. It improves seal integrity and enhances product protection.

2. Single Fold Turn Back: This folding technique creates a tighter seal than double fold, offering enhanced protection against external factors. It is optimal for products requiring a higher level of protection. The drawback is that the folding takes more time and precision during the sealing process.

3. Saddle Fold: It involves folding both sides of the tube, resembling a saddle shape. Saddle fold provides excellent seal integrity and visual appeal. It is typically used for premium products.

Choosing the Right Tube Size and Folding Option

When ordering metal packaging tubes from a supplier, it’s crucial to consider both the folding option and tube size. Different folding techniques may require varying tube lengths to ensure an effective seal. Factors such as the product’s viscosity, intended use, and desired level of protection should influence this decision. Consulting with the tube supplier can help in making informed choices tailored to the specific requirements of the packaged product.

Sealing metal packaging tubes is a pivotal step in ensuring the quality and integrity of the enclosed products. By understanding the importance of tube sealing and comparing different folding techniques, manufacturers can make informed decisions that not only preserve the contents but also contribute to a positive brand image and customer satisfaction.
