Abstract
Un rollo de bolsas de plástico de asas y un método para formar bolsas que contienen asas sin refuerzos. La fabricacion comprende: formar un tubo colapsado continuo para proporcionar multiples capas de pared; formar pares de sellos estrechamente separados transversales al tubo a distancias de la longitud de la bolsa de separacion; perforar una línea de desgarre para formar una línea transversal de debilidad entre cada par de sellos; doblar las orillas marginales del tubo colapsado hacia adentro, una hacia la otra; cortar y remover una region cortada en un extremo de cada segmento sellado del tubo doblado, para definir asas de lazada laterales y una region de boca de bolsa en cada bolsa, teniendo la boca de la bolsa porciones de orilla lisa internas mayores opuestas cortadas con troquel de las paredes de la bolsa adyacente, formadas por el tubo colapsado de película termoplástica, y que forman las orillas internas de las asas laterales. Se logra una mejor separacion de las capas de película mediante la perforacion de una porcion de orilla de boca de bolsa menor localizada centralmente entre las porciones de orilla lisa internas mayores opuestas, y rasgando la película termoplástica de desecho de la boca de la bolsa cortada con troquel, siendo la porcion de orilla de boca de bolsa menor para proporcionar una orilla rugosa a lo largo de la línea de perforacion central rasgada, para facilitar la separacion de las capas de película al abrir la boca de la bolsa, proporcionando de esta manera una serie de descontinuidades de la orilla de la película rasgada en la porcion de orilla de boca de bolsa menor perforada, para facilitar la separacion de las capas de película adyacentes bloqueadas más representativa de la invencion es la numero 6.
