Polypropylene cloth, from which big bags are made, is characterized by a low density of weaving. Therefore, special polyethylene inserts are used to protect the contents from external influences.
Technically — it is a package made of high-pressure polyethylene (HPP) by the corresponding container size. The film is strong enough to withstand transportation and automatic loading of the container.
The package is inserted inside the big bag before loading substances that are undesirable to excessive moistening. These are salt, sugar, cement, and many types of fertilizers. The insert can be ordered separately or together with a soft container. If necessary, it is sewn to the top of the walls of the big bag and does not affect loading. The insert is installed automatically, if special equipment is available, or manually.
