Abstract
A medical bag and method of manufacturing the bag from a thermoplastic resin by irradiating a ferromagnetic heating element which has been prepositioned between the mouth and receiving portions of the bag and which is caused to generate high frequence-induced heat. During subjection of the heating element to a high frequency magnetic field, the mouth portion and receiving portion of the bag melt about the element so that mouth portion, element and receiving portion are bonded together. This technique can also be suitably used for thermoplastic resins, for example, polyolefin resins, to which conventional high-frequency bonding cannot be applied.
