Abstract

LA INVENCION SE REFIERE A TAPAS DE ABERTURA FACIL PARA PRODUCTOS ALIMENTICIOS Y UN PROCESO DE OBTENCION DE ESTAS. ESTAS TAPAS ESTAN COMPUESTAS POR UNA HOJA METALICA (1) Y POR UNA PELICULA DE MATERIAL PLASTICO PRESENTANDO LA HOJA METALICA UNA PREINCISION MECANICA (3) Y LA PELICULA PLASTICA TERMORRETRACTIL PRESENTA UNA DEPRESION CONTINUA (4) SITUADA AL DERECHO DE LA PREINCISION MECANICA. ESTA DEPRESION, OBTENIDA POR ACCION DEL CALOR, PERMITE EVITAR EL DEFECTO DE "FEATHERING" Y LA PELICULA DE MATERIAL PLASTICO ES MAS BARATA Y MAS RESISTENTE A LA CORROSION QUE EL BARNIZ CLASICO.
