Container liners are used in transportation of dry bulk materials in a 20' container.  It is used to protect the product from containmination and also keeps the container clean.  Typically a inlet spot and vent is installed at the rear top of the container.  The outlet spout is placed at the rear bottom.  We have developed container liners with flexible suspension within the container, sift-proof seams, and advanced fixtures for easy and secure install of the container liners.
