S-LINER BARRIER

Effective 360° protection against permeation

SAIER pails are used in various industries with different filling goods. The period of time between the filling date and the use of the product can be several months, during which certain liquids, vapours or UV rays can penetrate the polymer structure of the packaging material. This can have a significant negative impact on the mechanical properties of the bucket and the quality of the contents.

With the S-LINER BARRIER, an internal barrier film reliably protects the contents in the pail by means of a welded base-wall film that covers the entire interior right up to the top edge of the pail. A barrier film attached to the inside of the lid additionally protects the contents from above, providing effective 360° protection.

The integrated barrier film protects the plastic polymer from changes and their permeation from the inside to the outside. The product properties of the contents and the stability of the bucket are thus preserved. At the same time, the filling material is protected from external influences that can affect the filling material through permeation from the outside to the inside. Possible changes to the product properties of the contents caused by oxygen or UV rays, for example, are thus effectively prevented.

The S-LINER BARRIER can be customised to different requirements using film technology. Whether round or square buckets, the S-LINER BARRIER inner film technology can be adapted to all container shapes and sizes. The multi-layer barrier layers of the inner film are only a few µm thick and therefore only a fraction of the usual bucket container wall thicknesses. Therefore, depending on the barrier requirement and the selected barrier layer, the recyclability of the bucket container is still up to 100 %.
