    摘要： Embodiments disclosed herein include multilayer films having at least an outer layer that includes 1) polyethylene elastomer and 2) ULDPE or VLDPE and that has a purge fraction greater than 20 percent as determined by Crystallization Elution Fractionation (CEF) test method. Embodiments disclosed herein also include related compositions to make such films and methods of making such films. The ULDPE or VLDPE can be made via Ziegler-Natta catalyst reaction techniques to provide the desired purge fraction.

    摘要： The invention relates to a multi-layer, expandable sleeve (100) for a printing press cylinder and to a method of manufacturing this expandable sleeve. The sleeve has an inner layer (110) with a hard surface inner jacket (112), which defines a longitudinal axis (A) and the cavity for mounting on the cylinder, and an outer layer (130) with a cylindrical outer jacket (132) for carrying an outer shell, a printing plate or a separate outer sleeve, in particular. An intermediate layer (120), manufactured in the form of a lightweight honeycomb having honeycomb cells oriented radially (B) to the longitudinal axis (A), is provided between the inner jacket (112) and the outer jacket (132).
    According to the invention, the intermediate layer (120) comprises at least one honeycomb layer (122-1, 122-2, 122-3, 122-4, 122-5) of fibre composite honeycomb consisting of fibre material embedded in a resin matrix that has been shaped coaxially around the longitudinal axis (A).
