Analysis of Different Types of Hand Stretch Film
I. Classification of raw materials used for manual stretch film forming: polyethylene stretch film, polyethylene stretch film, polyester stretch film, etc.
II. Classified by the purpose of stretch film: there are agricultural stretch films (plastic film and greenhouse film); Packaging wrapping films (such as food packaging films and packaging films for various industrial products), as well as breathable wrapping films for specific environments and purposes, water-soluble stretch films, and films with piezoelectric properties.
III. Classify according to the molding method of hand stretch films: there are extruded and then blown stretch films, called blown stretch films; The stretch film formed by extruding and plasticizing the molten material from the mold mouth is called the casting stretch film; The stretch film made by rolling and plasticizing raw materials onto a rolling machine is called a rolling stretch film.
