They consist of different layers of materials that improve the strength and desired characteristic. For example, a barrier film will have a base such as polyethylene or polypropylene, an inorganic high-quality vapour deposition layer (such as aluminum oxide for food packaging applications), and a proprietary barrier coat layer.
Properties of high barrier films
In this section, you will learn some of the benefits of high-barrier films and what makes them superior to other forms of plastic film packaging.Improved functionality: They can incorporate other features to make them more functional, for example,food packaging pouch with zipper this feature is perfect for ready-to-eat consumables.
Superior preservation: One of the reasons barrier packaging is highly-sought after is because of its superior preservation. They are great for locking in moisture and vapor while preventing contamination from external sources- This makes them great for storing food items and other sensitive materials like medical products and electronics.
Improved mechanical properties: High-barrier films have greater mechanical strength when compared to other products in the market. Their improved strength can be ascribed to advancements in polymer technology and the different layers in the film that add robustness to the material.
Flex resistance: Barrier films are highly resistant to flexing- this means they can be bent and deformed multiple times without losing strength and relevant characteristics.
Eco-friendly: Nowadays, manufacturers are shifting towards making more sustainable packaging materials that are better for the planet. High-performance film laminates like PE or PP-based laminates are friendly for the environment. They contain fewer materials that make them easy to recycle while retaining their strength and superior performance.
Excellent thermal properties: Premium-grade films can work under pressure. They have superior thermal, and pressure resistance. They can be used in an autoclave that can reach 2500F and 15 psi. Their thermal resistance makes them perfect for less demanding tasks such as cooking.
The superior performance and strength of barrier films make them very versatile across different industries. Film packaging are used in the following industries:
Food and beverages
Medicine and Pharma
Health and beauty
Décor materials
Electronics
Types of high barrier packaging
Packaging films can be grouped based on their level of performance, transmission rate, or base material. All these factors determine their application and their unique properties.
