A security film comprises at least two layers of polyethylene alkyl ester calendaring films. The polyethylene alkyl ester calendaring films are bonded and fit by polyacrylic acid pressure-sensitive adhesives. In order to ensure the security film to bear higher strength impact, the bonding strength between the two adjacent layers of polyacrylic acid pressure-sensitive adhesives can be different so that different forms of micro displacement happens when the security film endures different kinds of impact, and the basic films on different lamination can also undergo stretching to different extents. The micro displacement and film stretching lengthen the work path of the impact force, effectively weaken the impact strength and finally relieve the impact. The security film can ensure the common glass 3-5-6mm in thickness to have the effect of preventing injuries in accidents, theft and bullets after being bonded on the glass and meet various requirements of the CAS140-2007 standard on security films on glass of China Association for Standardization.
