    AbstractColor bright visual effects in polyolefin layered film materials for the production of consumer goods packaging are described. A multi-color light reflection by a package of films varies in case of a light angle change, depends on a thickness and number of layers. The relation between anisotropy, crystallinity and nanostructure of polyethylene and polypropylene films and their color in polarized light is identified. The fact of recrystallization of a part of fibrils in heat treatment in the course of films duplicating which reduces the effect of pleochroism is established by differential scanning calorimetry and electron microscopy techniques. The films duplicating processes with a simultaneous marking protecting the packed production against counterfeit are suggested

    The paper illustrates the possibility of manufacturing deployable test objects to configure aviation optical equipment for remote sensing of the Earth in the form of a set of fragments made of weatherproof polymeric materials using the method of digital inkjet printing of two types of prints. The main fragments with a fixed optical density include images of light bars against a dark background. Background fragments are monochrome. We have suggested a reasonable combination of materials for test objects fragments, and assessed their optical parameters and lightfastness
