Composite structures used to elongate the shelf life, prevent the smell and aroma permeation and provide protection against external factors.
Depending on the purpose and usage area of the product, metallic barriers with Aluminium layers or transparent barrier solutions coextruded with PA and EVOH additives which provide high flexibility and resistance are also available.

These are liners with low surface conductivity which are designed to prevent sudden energy discharges which can occur during filling & discharging in environments where explosive dusts and gases are present as well as to protect the filled the sensitive product from external conditions.

This is the type of liner used in 1&2 loop big bags which are preferable to mining, mineral, feed and fertilizer industries where the consumption is too high. These liners which can be fixed to the outer bag can provide air discharge when necessary and are easyto use.
