Coating for liquid packaging

Active, smart and intelligent packaging coating for liquids

The main role of packaging coating for liquid cartons, like milk and other dairy, is to provide a physical barrier between the package and food in order to prevent the item from damages (mechanical, physical, microbial contamination, etc.) and to maintain the best product quality.

Normally, it is required for packaging coating not to interact with the packed product inside the liquid carton, but current trends are focused on development of packaging that include certain interactions in order to extend the shelf life. For example: Antimicrobial packaging coating and biodegradable packaging coating. This new concept is also called active, smart or intelligent packaging. Packaging coating with special emphasis on novel technologies.

Application of packaging coating on liquid cartons

With a liquid product such as milk, a thin plastic film is needed inside the carton for reasons of product safety and shelf life. Here’s where packaging coating for liquid cartons comes into play. The exceptionally stringent hygienic requirements in the dairy industry imply that the production process in modern dairies needs to take place without manual intervention or interrupted lines. The packaging coating therefor, needs to fit seamlessly into this process.the

The end result of the manufacturing process is affected by different parameters such as:

  • Characteristics of the dairy (fat, proteins, temperature)
  • Instrumentation, number and time of processes
  • Packaging conditions

We can support you in developing packaging solutions for your specific project and through all project phases.

Edible films and coating for dairy products

Edible films and coatings are a trending concept. Not only because of their benefits on food products but also in novel product differentiation and its launching on the market. Coatings are aimed to have similar functions as those of conventional packaging with great ability to act as barriers to water vapour, gases, and flavour compounds.

US and European regulations

To ensure the safety of Food Contact Materials (like liquid cartons), and to facilitate the free movement of goods, EU law provides for binding rules that business operators must comply with.

The EU Rules on food contact materials can be of general scope, i.e. apply to all FCMs or apply to specific materials only. EU law may be complemented with Member States national legislation if specific EU rules do not exist.

In the US the Food and Drug Administration has issued the code of federal regulations (CFR).
