The present invention refers to improvements in a security bag using a tamper-evident system. The bag is manufactured based on a specific mixture of a low density and an ultra low density polyethylene, with which mechanical or resistance properties of the film results in a highly resistant bag capable of being recycled. The present invention also comprises a combination of longitudinal reinforcement seals which may vary from about 3 to about 5 millimeters, said reinforcement seals remarkably increasing the resistance of longitudinal edges upon incorporation thereof. Further, the carrying strip adhesive material is colorless and will be cracked and broken along with the carrying strip upon a tamper attempt at high or low temperatures. The improvements also include a detachable protective film disposed along the carrying strip, thus avoiding a premature adherence of the colorless adhesive to the adhesion portion of the bag rear panel. The strip is also useful as a closure, and environmental friendly because the use of lead seals is avoided, which otherwise would pollute the environment, thereby causing diseases such as cancer, leukemia and the like.
