Easy-to-tear thermoplastic polyvinyl alcohol film and its preparation method and application |
| abstract |
The invention provides an easily tearable thermoplastic polyvinyl alcohol film and its preparation method and application. The film of the present invention is obtained by adopting polyvinyl alcohol, thermoforming with a thermoplastic agent and stretching in the longitudinal direction. The film has the characteristics of anisotropy, the Hermans orientation factor is greater than 0.5, the tensile strength ratio of the longitudinal stretching direction and the transverse stretching direction is greater than 8, the tear strength ratio of the transverse stretching direction and the longitudinal stretching direction is greater than 3.5, and the film optical Excellent performance, can be used in the field of adhesive tape and so on. |
