覆する方法等が知られている。Laminated bodies containing metal foil such as aluminum foil, paper, etc. between thermoplastic resin film layers have been widely used in recent years, for example, for food packaging bags. However, in this type of laminate, the edge of the metal foil or paper is exposed on the surface at the end surface, so the metal foil may oxidize and corrode from the end surface during storage, or the paper may absorb moisture. There is a problem that the laminate deteriorates due to expansion. For this reason, various methods have been proposed to cover the end faces of this type of laminate to prevent deterioration. For example, 1) Skive method, in which approximately half of one side of the laminate is scraped off and folded back to cover the end face; 2) Adhesive, pressure-sensitive adhesive, etc. is applied in advance. How to apply coating tape to the end surface to cover it, ■
A method is known in which a molten thermoplastic resin is extruded onto the end faces of the laminate to cover the end faces.

In addition, method (■) has the disadvantage that the fold line and the thickness after folding are unstable because a relatively thick laminate is folded back. There are problems in that a device is required and the manufacturing cost is high because a covering tape coated with an adhesive, pressure-sensitive adhesive, etc. is used in advance. Furthermore, method (2), in which a thermoplastic resin coating film is formed on the end face by extrusion, tends to cause unevenness in the thickness of the coating film, and unevenness in the film thickness also causes unevenness in the adhesive strength of the coating film. As a result, there was a problem in that the coating film was likely to peel off, resulting in a decrease in protective properties.

かつ効率良く製造することができる。As explained above, in the manufacturing method of the present invention, a thermoplastic resin film for coating is fused to the end face of the laminate by laser beam irradiation to cover the end face, and the thermoplastic resin film for coating is fused by non-contact heating. This eliminates the risk of molten thermoplastic resin adhering to the heating means and reducing workability, unlike the conventional method of fusing by contact heating using a heating means such as a seal bar. Since the resin film can be reliably fused, there is no fear that the paper or metal foil will be corroded from the end surface, and an excellent laminate can be manufactured reliably and efficiently.

Resin films have various effects such as being able to provide excellent laminates at low cost since they are cheaper than covering tapes coated with adhesives or pressure-sensitive adhesives in advance.
