Why Internal Coatings Matter


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.

This is why selecting which type of interior varnish to use is important. Here are some tips for choosing the interior protective coatings:

  1. Identify the type of product: Different types of products require different levels of protection. For example, acidic products such as tomato sauce or fruit juice require a coating that is 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 shelf life of the product, the more protection it requires. Coatings that are resistant to moisture and oxygen are essential for products that have a longer shelf life.
  4. Look for safety certifications: Make sure that the internal coating used is compliant with safety regulations and certified by relevant authorities such as the FDA or EU.

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