Custom Packaging

IMPAK produces custom printed pouches and packaging with an emphasis on materials with distinctive barrier properties to protect products from the adverse effects of moisture, oxygen, light and more. Learn about our unique custom capabilities.

How to Choose a High Barrier Bag

High barrier bags are used to preserve and protect products. When paired with an oxygen absorber or desiccant, products enjoy even greater shelf-life and stability. However, selecting the appropriate package is not always as straight forward as it seems.

Right Sealer for Your Setting

Not every Industrial Vacuum Sealer applies to every application. There are different models and types of Vacuum Sealers available, and each one of those sealers has different features that can affect the way a production line works.
