Stretch films manufactured with Clearflex H&T CLH 196 have outstanding fracture mechanical properties, mainly Elmendorf tear strength along machine direction (MD) and puncture resistance. Moreover, the holding force is the key property of these films when used in automatic wrapping machines.
Main Applications: Clearflex H&T CLH 196 is recommended for production of super-power stretch films. Its properties, especially in terms of holding force and puncture resistance, make Clearflex H&T CLH 196 the ideal choice for packaging goods of irregular shape and for applications requiring a superior mechanical strength.
