Different from Blown film, tape casting is another method for producing film, more often for cling film. Firstly, the difference is the shape of material, for blown film, most of materials are processed as pellet, but when it comes to tape casting, the material has to be lamellar. Secondly, the end product through tape casting is more even and more transparent, it has greater heat seal ability. Lastly, it takes more financial and technical effort to set up a tape casting production since it requires more complex production technique.
