Silage film, also known as forage film or forage film, is a plastic film used to store silage feed. Silage refers to the process of processing high moisture forage (such as corn, cereal, etc.) into silage feed with a certain moisture content, and fermenting and storing it in a closed container to prepare feed with excellent quality. Silage film is widely used for the storage of silage feed, which can effectively protect the nutrients in the feed, prevent oxidation and mold, and maintain its fresh and attractive odor.Classification and selection criteria for silage filmsPolyethylene film is the most commonly used type of silage film, with strong toughness and good waterproof performance, while polypropylene film has good breathability and is commonly used for long-term storage.When selecting silage film, it is generally necessary to consider factors such as film thickness, strength, waterproofing, transparency, as well as storage conditions and duration, to ensure the selection of a suitable silage film for storing feed.
