Abstract: A film comprising a perforated layer, wherein the perforated layer is characterized by water vapor transmission rate (WVTR) of at least 300 gr/m2/day; and wherein the perforated layer is characterized by a liquid permeability of less than 0.6 gr when measured according to AATCC 35. Further, methods of manufacturing the composition of the invention are provided.

Abstract: A twine is disclosed. The twine comprises a mixture of at least 95 wt. % polypropylene and at most 5 wt. % additives. The twine is characterized by up to 8% vol. smectic phase. The percentage of the smectic phase is characterized using X-Ray Diffractometry (XRD). The additives are selected from, impact modifier, polyethylene, pigment, and UV stabilizer. The twine may be characterized by a ratio between a specific work to a relative stiffness, of between 40 to 55 [J*mm/KgF].

Abstract: A bale wrapping system includes an emitter configured to generate electromagnetic radiation within an emitted spectrum and a wrap. The wrap includes a melt layer containing an additive absorbent to at least some electromagnetic radiation within the emitted spectrum and a solid layer substantially free of the additive.

Abstract: Embodiments of the invention are related to a coating system and a method for coating a surface of a product. The system may include a coating unit, comprising; a droplet deposition assembly configured to deposit droplets of a coating material from a plurality of nozzles according to a predetermined deposition pattern, to form a coating on the surface. The system may further include a curing unit for curing at least one polymeric component included in the coating material and a control unit configured to receive the predetermined deposition pattern and control the coating unit to deposit the predetermined deposition pattern on the surface, such that the coating has a thickness deviation of less than 1 micron per 1 meter.

Abstract: A device and a method allow for adhering sealing tape to open end of a multilayer sheet, usable at the production line and at the installation site. The device comprise means for applying pressure and heat onto the sealing tape and cutting blades for removing protruding edges of the sealing tape after it was adhered. The method comprise providing of a sealing tape, attaching and adhering the sealing tape to an open end of a multi-wall sheet by means of heat and/or pressure and adhesive and removal of protruding edges using cutting blades.

Abstract: A supper hydrophobic surface (e.g., autoclean surface) and methods of making such a surface. The method includes forming an open porosity on a surface of a product, the open porosity including pores having undercuts and attaching functional nano-particles to the surface, such that the functional nano-particles are located inside the open porosity. The open porosity is formed by various methods such as, for example, co-extruding or applying a polymeric material with a blowing agent and/or etching the surface and/or directly printing a porous layer on the surface.

Abstract: Embodiments of the invention are related to synthetic printed boards and a method of printing and coating the synthetic boards. A synthetic board is printed, using for example, an inkjet printer, to form a pattern on at least one face of the board. The printed pattern is then cured. The printed pattern is coated with a transparent protective coating. The transparent protective coating has a thickness of less than 500 microns. The transparent protective coating is further cured to be hardened and weather-durable.
