A method of making a flexible package made of polymeric film is provided. The method comprises the steps of: a) obtaining post-industrial recycled material from post-industrial recycling of precursor polymeric film formed of precursor polymeric material which is substantially the same as the virgin polymeric material of step c), b) providing at least 30 weight-% post-industrial recycled material obtained in step a) based on the overall weight of the polymeric film, c) providing up to 70 weight-% of virgin polymeric material based on the total weight of the polymeric film, and d) jointly melting the virgin polymeric material and the post-industrial recycled material. The method comprises the steps of: e) extruding the molten polymeric material and molten post-industrial recycled material to form a polymeric film, f) providing print on one or both surfaces of the polymeric film, and g) converting the polymeric film into the flexible package.

The invention relates to a device for printing on edge bands including at least one printhead for producing a printed image on the edge band; a linear drive for moving the at least one printhead in a printing direction within a printing region between two end positions; a feeding apparatus for feeding the edge band into the printing region in a transport direction; and a control apparatus for controlling the at least one printhead, the linear drive and the feeding apparatus. The technical problem of technically and economically improving the process of printing on edge bands is solved in that the transport direction of the edge band is oriented substantially parallel to the printing direction. The invention further relates to a method for printing on edge bands.

A thermoplastic starch (TPS)/polylactic acid (PLA)/poly(butylene adipate-co -terephthalate) (PBAT) blend modified biodegradable resin is prepared by using a chain extender, and is prepared from the following raw materials: 20-30 parts by weight of TPS; 20-30 parts by weight of PLA; 40-60 parts by weight of PBAT; and 0.5-0.9 parts by weight of a chain extender KL-E. The preparation method is a two-step method: blending the TPS with the PBAT in a twin screw for granulating; mixing TPS/PBAT mixed granules with PLA granules, and dissolving the chain extender KL-E into an ethyl acetate solution. The chain extender KL-E can be uniformly distributed in PLA and TPS/PBAT mixed granules by using a spraying method, and the remaining short-chain molecules and terminal carboxyl molecules in the mixed granules can be changed into long-chain molecules.

A solar reactive mulch film comprising one or more layers of heat shrink material pre-strained at a predetermined temperature and tension. Immediately cooling the pre-strained layers retains molecular deformation stresses in the material which facilitate shrinkage but not expansion on exposure to solar radiation. The mulch film adapted to be laid over longitudinal growing beds and held tautly by burying its side edges in soil. Exposure of uncovered portions of film to solar radiation causes shrinkage in one or more directions whereby in combination with the weight of the soil holding it down, maintains tautness of the mulch over a growing period. Methods of manufacture and use of the same.

Provided is a method for producing a multilayer, surface-structured panel, in particular a multilayer, surface-structured flooring panel. The method includes the steps of: providing at least one plastic carrier panel, in particular in the form of a continuous strand; introducing surface structures on at least one side of the plastic carrier panel by means of embossing; applying at least one primer to the structured surface of the plastic carrier panel; printing the plastic carrier panel by direct printing to form a decorative layer; applying an anti-wear layer containing abrasion-resistant particles; applying at least one lacquer layer; and curing the layer structure.

The invention relates to an apparatus for automatically analyzing extruded films, in particular stretched films, wherein a neck-in portion is formed at each of both edges of the film at a specific distance from an extrusion lip of a film extruder along the longitudinal transport direction of the film, and a respective method. The apparatus comprises two edge detectors being arranged along a first line substantially transversal to the longitudinal direction and being spaced from each other by a specific distance, wherein each one edge detector is configured to detect, preferably to continuously detect the lateral position of one respective edge of the neck-in portion of the film, a calculation means for determining the spatial relation between at least one lateral position at the extrusion lip and a respective lateral position at the neck-in portion on the basis of the two lateral positions of the edges of the neck-in portion of the film.

The present invention relates to the technical field of wire-rod production equipment, in particular relates to an automatic production line for conductive tape and a manufacturing method for conductive tape, Automatic production of conductive tape brings about high production efficiency and low cost; it not only conducts pretreatment and corresponding detections of the conductors in the production process but also conducts follow-up treatment and corresponding detections of the conductive tape and thus improves the production quality of the conductive tape; in addition, it marks the abnormality position of the conductive tape which is abnormal during the withstand voltage detection so that the operator can accurately find out the abnormal section of the conductive tape.
