Definitions

  • the present disclosure relates to handling and storage containers, and more particularly to flexible containers, known as "Big Bag” and FIBC (Flexible Intermediate Bulk Container), used for the handling and storage of various bulk materials such as food grade or industrial material (in the form of granules or powder for instance).

  • FIBC Flexible Intermediate Bulk Container
  • a complementary liner made of a coextruded complex barrier film may be placed inside the outer body of the flexible containers.
  • the liner covers the whole inner surface of the outer body of the flexible container so the material filled in the liner does not come into contact with the fabric or seams of the outer body.
  • the liner is used to prevent leakage and provide barrier properties for example to water vapor and oxygen (also called dioxygen), avoiding contamination, moisture and oxidation of the stored product, oxidation being responsible for the deterioration in the quality of food products, including loss of organoleptic and nutritional qualities.
  • water vapor and oxygen also called dioxygen
  • MAP MAP preservations the harvests cereals and seeds from germination and insect pests. However, lots of insects still survive with only a few percent of remaining dioxygen inside the barrier-liner, and germination still occurs for many varieties of seeds.
  • An alternative to vacuuming and gassing processes in order to reduce oxygen ratio in a MAP is the use of dioxygen absorbers.
  • a liner for eliminating the above-mentioned disadvantages and for bringing new advantages to the related technical field.

  • the receptacle has at least one sheet of an oxygen permeable material allowing dioxygen to pass through it and to be removed from the stored product by the dioxygen absorbent material accommodated in the internal receptacle.
  • the rate of dioxygen in the product stored in such a liner may be inferior to 0,01%.
  • the structure of the liner thus avoids deterioration or decay of the big bag contents.
  • the liner is also compliant with EC food regulations.
  • the at least one internal receptacle is a pocket secured to the liner.
