Do you know the true importance of interior coatings in aluminum packaging? Internal coatings are used on aluminum packaging to protect their contents from contamination and corrosion. Without internal varnishes, aluminum may interact with the contents, altering their taste and odor, so selecting which interior varnish to use is essential. 

Tips for choosing interior protective coatings:

1. Identify the type of product: Different products require different protection levels. For example, acidic products such as tomato sauce or fruit juice require a coating resistant to acid, while carbonated beverages require a coating that can withstand high pressure.
2. Consider if it is an edible product: Products for ingestion must use FDA-approved BPA Non-Intent varnishes that may be in contact with edible products.
3. Consider the shelf life of the product: The longer the product's shelf life, the more protection it requires. Coatings resistant to moisture and oxygen are essential for products with a longer shelf life.
4. Look for safety certifications: Ensure that the internal coating used complies with safety regulations and is certified by relevant authorities such as the FDA or EU.

In conclusion, internal coatings are essential to consider when selecting aluminum packaging. You can choose the right option by understanding the type of product, shelf life, and safety certification.
