All you need to know about the Barrier Films

We are lucky to live in a world where miraculous inventions like Flexible packaging films may make our daily lives easier and more pleasurable. Many aspects of our daily lives are affected by barrier coatings. Barrier films are used to improve and enable a wide variety of experiences, from the everyday items we use in our kitchens, offices, and elsewhere, to large-scale industrial and medicinal uses. Barrier films' primary function is to prolong the shelf life of their contents while also improving its aesthetic value and reducing production costs and environmental impact.

The different types of barrier films that are used in the packaging industry

In general, the packaging industry depends on three primary kinds of barrier films in order to serve to a wide range of different end usages. In order to meet the requirements for safe and fresh contents within packages, many types of Flexible packaging films, including metalized films, transparent barrier films, and white barrier films, are used.

·       Metalized Barrier Films:

Metalized films are used to produce a barrier against the transfer of gas, oxygen, water, vapour, and ultraviolet radiation to and from the contents of the package. These films are provided with a thin layer of coating with metals like aluminium, and they are utilised to create the barrier. In addition, there are three primary categories of metalized barrier films: high moisture barrier (HMB), high speed barrier (HSB) with high hot tack, and ultra-high barrier (UHB).

·       Transparent Barrier Films:

They are used in the packaging sector to stop the defacing or degradation of printed information and images, as well as to halt the absorption of moisture and prevent it from happening. Aroma Barrier Film, Aroma and Oxygen Barrier Film, and High Barrier Film are the three subtypes that may be assigned to barrier films according to the coatings and chemical characteristics that distinguish them.

·       White Barrier Films:

On one side, these white opaque cavitated BOPP films have been treated, and on the other side, a PVdC coating has been applied. They exhibit great dimensional stability as well as stiffness, in addition to their outstanding moisture and gas barrier qualities.

Potential future of the Sustainability of the Packaging Industry?

The advances that have been made by top BOPP film manufacturers have, indeed, made it possible for the packaging sector to have a reduced carbon footprint. For instance, a newly developed category of Metalized films that are composed of high-density PE resins are gradually replacing non-recyclable materials with totally recyclable and complete PE structures that are simpler to recycle.

In order for consumables to be able to be sold to customers and utilised by customers over an extended length of time, BOPP films are designed to preserve the consumables' freshness and maintain their original qualities for an extended period of time while they are in transit and on retail shelves. In the end, barrier films lead to reduced waste, which leads to the development of smaller packages that make better use of their contents.
