Abstract
Procedimiento para la fabricación de una lámina en material plástico con burbujas, para embalaje y producto obtenido. Comprende una fase en la que se calienta el material plástico entre 170°-250°C procurando su fusión, y a la vez preservando la integridad del material, otra fase en la que se adiciona y se mezcla un aditivo anticorrosivo a la masa fluida, posteriormente dicha mezcla se extruye y se configura en dicha lámina una pluralidad de cavidades, por último se une la citada lámina a otra lámina lisa o con cavidades por termosoldadura y simultáneamente inyectando aire que llena al menos parcialmente las citadas cavidades. El material plástico obtenido comprende las siguientes características técnicas: ser polietileno de baja densidad (LDPE) e incorporar un aditivo anticorrosivo, compuesto de un anticorrosivo fenólico y coestabilizantes de azufre y fosfito, integrado en una fase de obtención del material en la que dicho polietileno está en estado fundido.Procedure for the manufacture of a sheet in plastic material with bubbles, for packaging and product obtained. It comprises a phase in which the plastic material is heated between 170 ° -250 ° C ensuring its fusion, while preserving the integrity of the material, another phase in which an anticorrosive additive is added and mixed to the fluid mass, subsequently said mixture is extruded and a plurality of cavities is configured in said sheet, finally said sheet is joined to another flat sheet or with heat welded cavities and simultaneously injecting air that at least partially fills said cavities. The plastic material obtained comprises the following technical characteristics: being low density polyethylene (LDPE) and incorporating an anticorrosive additive, composed of a phenolic anticorrosive and sulfur and phosphite co-stabilizers, integrated in a phase of obtaining the material in which said polyethylene is in molten state
