What is the difference between metalized pouches and foil pouches? At first sight, the two types of the pouch are similar. However, they offer very different properties, making each of them more or worse suitable depending on the applications.

Metallised and foil pouches are manufactured using a laminated aluminum, PET, PP, and PE and provide an extremely effective barrier protection against spoiling factors such as moisture and oxygen infiltration. They are also very durable, offering your product extra protection during transit.

Foil pouches being able to withstand very high temperatures, meaning they are able to be used in autoclaving environments. As a result, these pouches can be used in direct food contact applications.

Foil pouches are widely used by the healthcare and pharmaceutical sector. This is due to foil packaging’s strong barrier properties, meaning medical samples and devices can be safely transported whilst remaining sterilized.

Metallised pouches are commonly used to house bandages, Petri dishes, medical accessories, and other medical instrument sets. This metalized pouch gives both sparkle & reflection to help display your products in a very attractive way.

The range of pouches covers 150ml up to 4 liters. The pouches have a bottom-gusseted base allowing them to sit on the shelf to create an appealing display.

You might have seen foil pouches being used for packaging health food and nutrients (a market sector that has been dramatically expanding in recent years).

This is primarily due to the packaging’s protection against contaminants and moisture but also the protection against UV light, this means that your nutrients, protein powder or health food stays more effective for longer. Another increasingly popular application for Aluminium and Metallised pouches is within the drink sector, most notably Ice & Easy

Properties Of Metalized Pouches

Metallised pouches are produced from polymer film layers coated with a thin layer of metal ions such as aluminum, nickel, and chromium. The most commonly metalized polymers are polyethylene terephthalate and polypropylene. Metallised pouches are sometimes preferred over traditional plastic ziplock bags because they have reduced permeability to light, water, and gases, allowing for longer storage of food-based products.

Additionally, the metalizing process does not alter the pouches ability to be heat sealed for security. This process results in a bag that is both aesthetically pleasing and durable. They are very popular for food packaging since the process creates either a beautiful glossy or matte bag.

Properties Of Foil Pouches

foil pouches, on the other hand, is made from thin sheets of the metal aluminum. They act as a total barrier that completely blocks out light and oxygen, making it bad for long-term storage of perishable goods.

Foil pouches are great for the aseptic packaging of liquid products and long life foods. As a result, they can be several times more expensive than the metalized pouch. Foil pouches are also often seen with an interior coating of polyethylene that allows them to be heat sealed together.


 So which one is best for my needs?

If you plan to store perishable food products and powdered substances in ziplock style bags, we recommend using the semi-permeable metalized pouches as they provide a durable barrier that allows some moisture and gas to pass through, preventing the food products from becoming rancid. For liquid-based products such as juices, oils, and lotions, we would recommend the aluminum pouches.
