Abstract

A bag (1), particularly for transfusion blood, has a reinforced head (6), equipped with tubes (5) for feeding and drawing a liquid to be retained in the bag, and substantially rectangular walls made of a composite thermoplastic film of bonded or coextruded layers of polyvinylchoride (2) and a polyolefin (3), the polyolefinic layers being located at the interior of the bag. The reinforced head is formed by over- turning the composite film forming the bag body or by application of a portion of the same composite film as is used to form the bag body, and by welding, the part of the composite thermoplastic film forming the reinforced head having a PVC layer located at the interior of the reinforced head and closely in contact with the feeding and drawing tubes.
