摘要： An improved method and an improved device for producing a monoaxially or biaxially stretched plastic film are distinguished, inter alia, by the following features:
In the intermediate space (Z) tapering in a wedge shape to the contact line (111, 11′) between the melt film or plastic film (5, 5′) and the roller jacket (9) spaced apart therefrom or the roller surface (9′) spaced apart therefrom of the cooling roller (1, 1′), at least one device for preventing precipitation of condensate (K) in the intermediate space (Z) is used and is designed such that precipitation of condensate (a) on the underside (5a) of the melt film or plastic film (5, 5′) facing the roller jacket (9) or on the roller jacket (9) of the cooling roller (1, 1′) is prevented, and/or a condensate (K) which has precipitated there evaporates or vaporises, and/or condensate disposed in the intermediate space (Z) is transported away, suctioned off, or blown out and/or runs out to the side.-

摘要： Provided is a method of making a sterilized flat plastic bag including the steps of: forming a roll of a tubular polymeric film in a blown film extrusion process, providing the roll of tubular polymeric film to a bag making process, and forming a sterilized flat plastic bag, wherein the tubular film is not slit in the longitudinal direction during any step of the method, and therefore avoids the necessity of a separate sterilizing step. Also provided is a sterilized flat plastic bag made according to the foregoing method of making and a method of using such a sterilized flat plastic bag to collect and retain a product sample and eliminate product contamination. The sterilized plastic bag made according to the above method provides improved tear strength and resistance to rupture when containing product.

摘要： A method for producing a tube, which includes: extruding a melt-fabricable fluororesin from a mold of an extruder into a form of a tube, leading the extruded melt-fabricable fluororesin to a cooling device to cool the extruded melt-fabricable fluororesin, and winding a resulting cooled tube onto a winding reel using a winding device. A gas is fed from a head end of the tube wound onto the winding reel into a hollow of the tube, the gas in the hollow is allowed to pass through a gas-introducing entrance of the mold and then through a gas-discharging hole of the mold to discharge the gas outside, thereby allowing the gas to flow along the hollow, and an internal pressure of the hollow is kept higher than atmospheric pressure and lower than 0.5 kgf/cm2.

摘要： The formation of paraffin condensate on an inner cooling body of a blown film extruder can be either avoided or allowed in a controlled manner and then removed, thereby reducing damages to the film tube or even avoiding them. In an inner cooling body for a blown film extrusion line, the inner cooling body includes a shell around which a blown film tube, coming from the annular die, can ascend against gravity or can descend with gravity when the blown film extrusion line is running. The shell has a fraction condensate diverter for keeping paraffin condensate or any other condensate away from potential contact points of the blown film tube on the shell.
