Transparent High Barrier Films
When an ultra-high barrier film is required, we usually recommend one of the many heavy duty foil structures we have available, such as PAKDRY7500. Clearly, however, opaque structures are unsuitable when it is necessary (or desirable) to see the contents inside of your package. Whether you are conducting tests on bacteria growth in a soil sample, or you sell visually appealing moisture-sensitive bath bombs, you need a clear pouch with a high barrier against the elements. Through chemical treatments and co-extrusion and lamination techniques we can provide clear materials with near unbeatable barrier levels. We also work with customers who have more specific needs to develop custom clear high barrier multi-layer film specs.
Not just science fiction any more.
The quality tested materials and products listed in the table below all offer transparency with high oxygen and moisture barrier properties.
