The barrier function of laminated food packaging is crucial to maintaining the quality, safety, and shelf life of packaged food products. Barrier properties refer to the packaging’s ability to prevent or minimize the passage of external elements such as moisture, oxygen, light, and odors into the packaged food, as well as the migration of substances from the packaging material into the food.
There are many ways to get barrier function for recyclable laminated pouches. We will discuss in this article in details.

Barrier film, often referred to as barrier packaging or barrier material, is a type of packaging material designed to provide a protective barrier against external factors that can degrade or compromise the quality, freshness, and shelf life of products. Barrier films are used in various industries, including food packaging, pharmaceuticals, electronics, and more, where it is crucial to protect the contents from moisture, oxygen, light, and other environmental factors.
Example: foil ( AL layer)
A coated film refers to a thin layer of material that has been applied to the surface of another material or substrate. This coating can serve various purposes, depending on the specific application and the properties of the coating material. Coated films are commonly used in a wide range of industries and products for purposes such as protection, enhancement, or modification of the substrate material’s properties.
Barrier coatings are used to create a barrier against gases, liquids, or other substances. They are commonly applied to packaging materials to extend the shelf life of food products or protect sensitive products from environmental factors.
Example: PVOH, AIOx, SiOx,
Metalized film, also known as metallized film or metallized polyester film, is a type of plastic film that has been coated with a thin layer of metal, typically aluminum. This metal coating is applied to one side of the plastic film substrate using a vacuum metallization process, which involves evaporating a fine layer of metal onto the film surface in a vacuum chamber. The result is a film with a shiny, reflective, and metallic appearance on one side, while the other side remains the original plastic substrate.
Metalized films provide excellent barrier properties against oxygen, moisture, and UV radiation. This makes them suitable for packaging applications where protection and preservation of the contents are crucial, such as food packaging and pharmaceuticals.
Metalized films are commonly used in flexible packaging materials for snacks, candies, cosmetics, and more. They provide a visually appealing, moisture-resistant, and protective barrier for the contents.
Example: Metalized PET, Metalized CPP, Metalized PE, Metalized OPP,
A “barrier additive film” refers to a type of film with barrier additive during film blowing that is designed to provide a barrier against specific substances, such as gases, moisture, or other contaminants. These films are often used in packaging materials to protect the contents from external factors that could degrade the product’s quality, shelf life, or safety.
Example: EVOH, PA,
The most often use film structure to achieve high barrier functions for recyclable laminated packaging are:
PE / EVOH PE
MDO-PE / EVOH PE
Barrier MDO-PE / PE
MDO-PE / Metalized MDO-PE / PE
Barrier MDO-PE / Metalized MDO-PE / PE
AIOx OPP / CPP
OPP / Metalized CPP
