International que mide la resistencia a la adherencia en caliente de los materiales, en particular las pel\u00edculas utilizadas en los envases. La resistencia a la adherencia en caliente se refiere a la capacidad de un sello para resistir fuerzas disruptivas mientras el sello a\u00fan est\u00e1 caliente, lo que es un desaf\u00edo com\u00fan en las operaciones de formado y llenado. La prueba se realiza normalmente utilizando una m\u00e1quina de prueba de retardo fijo o variable, con el objetivo principal de determinar cu\u00e1nta fuerza se requiere para despegar una muestra sellada despu\u00e9s de la exposici\u00f3n al calor.<\/p><p data-start=\"1270\" data-end=\"1656\">Esta prueba es vital porque durante los procesos de envasado, especialmente en las industrias alimentaria y farmac\u00e9utica, los envases suelen estar sometidos a fuerzas mientras a\u00fan est\u00e1n calientes. Si el sellado falla prematuramente, el contenido podr\u00eda verse comprometido, lo que provocar\u00eda la p\u00e9rdida o contaminaci\u00f3n del producto.
