Abstract

Procedimiento para formar juntas en tapas para recipientes, cuyas tapas se fabrican de una resina de poliolefina caracterizado porque comprende las etapas de introducir un compuesto de plastisol tal como uno compuesto por 100 partes de polímero de cloruro de vinilo 50 a 80 partes de plastificante en la tapa, dar al plastisol forma de junta con la configuración deseada, formándose la tapa de un polímero de olefina tal como uno elegido entre; polipropileno, y polietileno que prácticamente no es sensible a la activación térmica por energía eléctrica de radiofrecuencia, y estando compuesto el plastisol por polímero de cloruro de vinilo y un plastificante que tiene una constante dieléctrica aproximadamente entre 6 y 8 y un factor de pérdida aproximadamente entre 2 y 25; fundir el plastisol en la tapa calentando dieléctricamente el plastisol con exposición a una fuente de energía eléctrica de radiofrecuencia y dejando enfriar después el plastisol fundido para formar la junta.
