摘要： A tear resistant film comprises more than five layers situated one on the other in a parallel array. The layers are individually selected from a stiff polyester or copolyester, a ductile polymeric material, and optionally, an intermediate material. The stiff polyester or copolyester is oriented in at least one direction. Tear resistance may be measured in a Graves area test and reflects the ability of the film to absorb energy. The films of the invention are useful in many articles including security control laminates for glazing members.

摘要： A tear resistant film comprises at least three layers situated one on the other in a parallel array. The layers are individually selected from a stiff polyester or copolyester, a ductile sebacic acid based copolyester, and optionally, an intermediate material. Tear resistance may be measured in a Graves area test and reflects the ability of the film to absorb energy. The films of the invention are useful in many articles including security control laminates for glazing members.

摘要： A dispensable multilayer film having alternating layers of a ductile material, a brittle material, and optionally an intermediate layer. The film has excellent strength in its longitudinal and transverse directions but can be transversely cut by forces of less than 9 Newtons on the cutters of commercially available table top tape dispensers. At least one surface of the sheet material can be coated with a functional material.
摘要翻译： 具有延性材料，脆性材料和任选的中间层的交替层的可分配的多层膜。 该膜在其纵向和横向方向上具有优异的强度，但是可以在市售的台式胶带分配器的切割器上横向切割小于9牛顿的力。 片材的至少一个表面可以涂覆有功能材料。
