Aluminum Packaging vs. Metalized Packaging: Differences and Applications

Aluminum, a common packaging material, has been used in many industries, including the food industry, transport, and construction. Nevertheless, in recent years a big competitor of aluminum packaging came into view, known as metalized film packaging. This article discusses packaging, its differences, and its applications in the food industry.

Main features

Aluminum packaging

aluminum film packagingAluminum foil offers great packaging because it is a flexible and thin sheet of material. But the main drawback is that it can easily get damaged. This is why aluminum is used in combination with other materials to enhance its properties, making aluminum foil for food packaging suitable. The main features of aluminum include

 

 

 

 

 

  • Flexibility
  • Ease of use
  • Easily printed
  • Waterproof
  • Greaseproof
  • Lightweight
  • Protects from light and oxygen for an extended period
  • Toughness
  • Resistant to fire
  • Recyclable

Metalized film packaging

 

Metalized film packaging differs from aluminum packaging in the aspect of its material. The metalized film does not contain aluminum as the main component; instead, it is only sprayed on the top. The aluminum spray makes this type of cinema cost-effective and a good barrier for packaging. The main features of metalized film packaging include:

  • Flexibility
  • Lightweight
  • Visual appeal due to the shine from the aluminum spray

Main applications in the food industry

 

Laminates with aluminum foil

There are many types of flexible films that can be made with aluminum foil for food packaging, including:

1)       PET ALU PP

This triple film is commonly used to create pouches used for pickled products. In addition, it allows heat sterilization and printing on it.

2)       PET ALU PE

This triple film protects against light, oxygen, and moisture. It is best for making foiled bags of sauces, olive oil, spices, and coffee.

3)       OPP ALU PE

This triple film provides thermal, mechanical, and elastic properties and is used for coffee packaging.

4)     PET ALU OPA PP

This quadruple film is impact-resistant, thus suitable for liquid packaging. In addition, it allows heat sterilization, so it is great for sauces, purees, custards, and cured meats.

Laminates with metalized film

In recent years there has been an increased use of metalized film to retain the freshness and taste of products.

1)       MET PE

This double film offers protection against moisture and gases. It is best for packaging sauces, snacks, smoked salmon, and cheese slices.

2)       PAPEL MET

This double film offers heat-sealing for both hot and cold, commonly used for dessert lids.

3)       OPP MET PP

This triple film provides good protection as snack packets but not as stand-up foiled bags.

4)       MET PE PEL

This triple film is used as peel-able film, which is best for processed meat products, snacks, cheese slices, meat slices, and sausages.
