Abstract
A glass protecting film including at least 5 or more layers, of which at least one layer is the layer which comprises polyester having 1,4-cyclohexane dimethanol is one of the components, and a glass protecting including a multi-layer structure which comprises at least two kinds of thermoplastic resin, of which the difference of glass transition temperature is 40° C. or less, the face-impact strength is 18 J/mm or more, haze is 3% or less, are films which excel in transparency, tear resistance, and impact resistance, and are suitable for protecting glass and preventing damaged glass fragments.
Claims24
A glass protecting film, comprising a multi-layer structure which comprises at least two kinds of thermoplastic resin of which the difference in glass transition temperature is 40° C. or lower, in which face-impact strength is 18 J/mm or more, in which haze is 3% or less and tearing-propagation resistance in the longitudinal and/or width direction is 10 N/mm or more.
A glass protecting film, comprising a multi-layer structure which comprises at least, two kinds of thermoplastic resin of which difference in glass transition temperature is 40° C. or lower, in which impact strength is 8 to 40 J, in which haze is 3% or less and tearing-propagation resistance in the longitudinal and/or width direction is 10 N/mm or more.
