Abstract
Systems and methods of a container having a tack welded fin seal. The container may include a film, a tack weld joining a first outer portion of a first edge and a second outer portion of the first edge, and a fin seal joining a first inner portion of the first edge of the film and a second inner portion of a second edge of the film. The container may include a faceplate integrally molded to an outer layer of a first end portion of the film. The faceplate may include substantially the same composition as an outer layer of the first end portion, such that no distinct layers are formed between the faceplate and the film. The tack weld may be formed at a tack welding system, and the fin seal may be formed at a fin sealing system having a mandrel.
