Abstract
Un cierre para un paquete de plástico que puede volverse a cerrar con un sello desprendible que no puede volverse a cerrar y que revela malos manejos, que da una indicacion obvia de que fue roto cuando el paquete se abre por primera vez, y que no puede volverse a sellar luego de abrirse por primera vez. El cierre tiene una primera red, a la que se une un primer material de resina polimérica, y una segunda red frente a la primera, y a la que se une un segundo material de resina polimérica. El primer material de resina polimérica tiene una gran afinidad con un segundo material de resina polimérica. Uno de los materiales de resina polimérica primero y segundo tiene una baja resistencia cohesiva, de manera que se romperá en lugar de estirarse bajo tension. Unas barras de sellado de sello desprendible unen entre sí las redes primera y segunda, uniendo los materiales de resina polimérica primero y segundo uno al otro. Cuando el sello desprendible se abre por primera vez, una porcion de uno de los materiales de resina polimérica primero y segundo con baja resistencia cohesiva permanece unido al otro de los materiales de resina polimérica primero y segundo, y se separa del resto. La separacion causa una decoloracion en el adhesivo, dando una indicacion visual de que el sello desprendible se rompio. La invencion también incluye un método para hacer el sello desprendible que no puede volverse a sellar y que revela malos manejos.
