Methods for producing a stretch film are provided, including disposing one or more extruders in fluid communication with a stock of virgin resin; heating the virgin resin to a molten state; delivering the molten virgin resin to a die; and extruding the molten virgin resin through the die onto a casting roll, thereby creating a cast stretch film. Methods for delivering the molten virgin resin onto a casting roll of varying sizes and set temperatures; and of moving a resulting film onto a secondary chill roll of varying sizes and set temperatures, are also provided. Finally, methods for moving the film from either the casting roll or the secondary chill roll onto a slitting assembly, dividing the film using one more interior or exterior slits, and then capturing and gathering the trim waste but not reintroducing the trim waste back into the production process are also disclosed.

Disclosed are a new silicone cold-extrusion lamp belt and its manufacturing method. The manufacturing method includes the following steps. S10: Select a PCB and use the PCB as a substrate. S20: Set LED lamp bead spot-welding units arranged in an array formed on the substrate to obtain a target board. S30: Extrude a slurry which is formed by a food-grade silicone and coat the slurry on an outer surface of the target board to form a lamp skin. S40: Cut the target board into at least one lamp belt substrate. S50: Heat and bake the lamp belt substrate to obtain a lamp belt. This disclosure has the advantages of feasible design, low manufacturing cost, high resistance on cracking, wearing, yellowing, high/low temperature, good fire resistance, environmental friendly and harmless to human safety, high transparency, high light emitting efficiency of the lamp, and applicable for indoor/outdoor lamp belts.

A multilayer film, including: a barrier layer in which an unstretched first film layer containing a first resin, and an unstretched second film layer containing a second resin different from the first resin are alternately and repeatedly laminated; a pair of unstretched first outer layers sandwiching the barrier layer; and a pair of unstretched second outer layers sandwiching the pair of unstretched first outer layers, wherein the average thickness per layer of the first film layers is 10 to 1,000 nm, and the lamination number of the first film layers in the barrier layer is in the range of 50 to 5,000.

A method for forming a multilayer plastic sheet material (1) for floor and/or wall panels, wherein a first polymer mass comprising a rigid PVC is melted under pressure and is passed through an extruder head at a specified discharge rate in the form of a plastic strand in sheet form that is provided with one or more layers so that a multilayer plastic strand is formed, which is passed to two or more rolls of a finishing stand, which processes the multilayer plastic strand into a sheet of defined thickness, which is then led away via a transport device to a sawing device to be cut to the desired length, wherein, after the plastic strand in sheet form leaves the extruder head, it is first passed between a top roll and a bottom roll of a roughing stand, wherein the speed of the rolls of the finishing stand and the rolls of the roughing stand is synchronized with the discharge rate of the plastic strand in sheet form from the extruder head, so that said plastic strand is processed without stress.

The present invention provides a flexible mat with fluid conduit, methods of manufacture thereof and apparatus for the manufacture thereof. In an embodiment, the mat comprises a base layer, one or more fluid conduits and a thermoplastic bonding tape that attaches the fluid conduits to the base layer. The base layer can be a textile fabric, mesh or netting, or a flat flexible sheet. The base layer is preferably also formed of a thermoplastic layer. The fluid conduits can carry heated or cooled fluid, such as water, that can be used for heating or cooling an environment in which the device is deployed. For example, the device can be used for heating or cooling in a greenhouse environment. The fluid conduits can additionally or alternatively carry irrigation fluids, such as water or treated water, for irrigating plants and crops. The fluid conduits can additionally or alternatively carry gases, such as carbon dioxide (CO.sub.2) or carbon dioxide mixed with other gasses, for treating plants and crops.

A plastic floor board processing technology using digital printing, aiming to solve the problem relating to the high production cost, comprising the steps of: preparing a base material; blending the base material; extruding the blended base material into a mold to form a stone-plastic base material; adjusting a gap between a surface embossing roll and a bottom embossing roll to enable the stone-plastic base material to pass through the gap; generating embossing patterns and positioning marks at equal intervals on a surface of the stone-plastic base material; cooling the stone-plastic base material; cutting the stone-plastic base material into plastic floorboards; using a digital printer to print the plastic floorboards. According to the present disclosure, patterns are directly printed on the surface of the stone-plastic base material, which avoids the processes of arranging a color film and a wear layer, lowers the production cost and improves the production efficiency.
