“What is Barrier? Barrier properties are critical for optimal packaging that keeps your product fresh on the shelf. The level of barrier protection defines how permeable the material is, or how much gas, moisture, or aroma compounds can pass through the film itself. Gases such as oxygen, carbon dioxie and nitrogen can influence your product’s freshness and shelf life, depending on its unique requirements. 

​​

• Low Barrier films are ideal for products that need to ‘breath’, such as fresh produce

​

• Standard Barrier films are suitable for products that are not as vulnerable to exposure to gases or moisture, such as frozen or nonfood products.

​

• High barrier films offer optimal protection for products that are susceptible to spoiling or rancidity due to exposure, by incorporating materials like aluminum, VM-PET or EVOH. Many products that use fresh ingredients require high barriers such as meat, cheese, seafood, coffee and tea.
