ABSTRACT OF THE DISCLOSURE A bag structure includes a tubular bag body closed at one end and at its edges but open at the bag top. A top closure is affixed to the bag body covering the bag top. The bag body includes opposite wall panels which include a opposite outer layers and opposite inner layers, in which the outer layers are formed from a material that is more readily fusible than the material of the inner layers. The top closure includes opposite attachment flanges composed of a material that is more readily fusible to the outer layer than the inner layer. In one specific embodiment, a heated pressure bar is applied to heat seal the attachment flanges of the top closure to the outer layers of the bag body, while the inner layers of the wall panels remain intact and are not fused together. The inner layer material has a fusion temperature higher than the temperature at which the outer layers and top closure attachment flanges fuse.
