Abstract
A resealable bag includes a first end, a second end, a first transverse seal sealing the first end and a second transverse seal sealing the second end. The second transverse seal is part of a weak seal zone of the bag that can be readily unsealed by a consumer by hand. The bag further includes a third transverse seal between the first transverse seal and the second transverse seal, closer to the second transverse seal than the first transverse seal. The third transverse seal is at least partially longitudinally aligned with the second transverse seal and can be selectively unsealed and resealed by the consumer by hand. In one embodiment, a fourth transverse seal is located between the first transverse seal and the second transverse seal, while being at least partially transversely aligned with the third transverse seal, and part of a strong seal zone of the bag.
