    Abstract: To provide a method for producing a laminated film, a laminated film, and a packaging container, which are capable of reducing an environmental load and suppressing generation of air bubbles in an adhesive layer. In the method for producing a laminated film. a solventless adhesive has a viscosity at 50°C of from 700 to 2000 mPa s. The coating device further includes a coating unit, the coating unit including: a pair of rolls, a plurality of transfer rolls configured to sequentially transfer and supply the solventless adhesive, and an application roll disposed on the opposite side of a fine clearance from a doctor roll, the doctor roll being one of the plurality of transfer rolls and positioned at an end on a side where supply of the solventless adhesive starts. A peripheral speed of the doctor roll is from 1.0 to 10.0 m/min.

    Abstract: Provided is a coating device capable of forming a non-coated portion at an end portion of a web and adjusting a coating width without deteriorating productivity. The coating device according to the present invention includes: a coating bar extending in a web width direction; a partition disposed below an axial center of the coating bar in the vertical direction, the partition extending in the web width direction; and an upstream container and a downstream container disposed on an upstream side and a downstream side in a web conveyance direction, respectively, with the partition interposed between the upstream container and the downstream container, the upstream container and the downstream container including side plates having both ends on a web width direction side are disposed inward in the web width direction with respect to both ends of the partition on a web width direction side. The partition has a flow path for discharging the coating liquid from a position within a range of a web width and outside the side plates in the web width direction.
