A method for recycling of packaging material is disclosed. The packaging material comprises a multilayer material (10) comprising a metal layer (30) and at least one polymer layer (20, 40). The method comprises placing the packaging material in a vat (310) comprising a separation fluid (330) to produce a mixture of metal shreds from the metal layer (30), plastic shreds from the polymer layer (20, 40) and residual components. The separation fluid comprises a mixture comprising a mixture of water, a short-chained carboxylic acid, phosphoric acid and an alkali metal hydroxide solution.

A removable adhesive member and a display device using the same is provided. The removable adhesive member includes a first adhesive section, a first connecting section, and a tearing portion. The two opposite surfaces of the first adhesive section respectively adhere to the two objects. The first connecting section is connected to the first adhesive section. The first connecting section includes a first adhesive layer and two first protective layers. One side of the first adhesive section extends to form the first adhesive layer. The first protective layers are respectively laminated to two opposite surfaces of the first adhesive layer. The tearing portion is connected to the first adhesive section through the first connecting section, thereby avoiding rupture in pulling the tearing portion. The tearing portion is conveniently pulled up by a user, such that the first adhesive section removes from the objects to disassemble the objects.

A roll conveying unit of a joined body manufacturing apparatus includes a rotating unit and a suction unit. The outer peripheral surface of the rotating unit includes a contact suction portion that makes contact with a first back surface. The rotating unit rotates while bringing the contact suction portion into contact with the first back surface. The suction unit suctions the second layer from the contact suction portion through pores of the first layer, to thereby form a suctioned portion attracted to the contact suction portion under suction, in a laminated body of the first layer and the second layer. The peeling unit peels the coating film from the second back surface of the suctioned portion of the film-attached joined body.
