(EN) REFRIGERANT FOR ISOTHERMAL BAGS
(ES) PRODUCTO REFRIGERANTE PARA BOLSAS ISOTERMICAS
(FR) PRODUIT REFRIGERANT POUR SACS ISOTHERMES
Abstract
(EN) The invention relates to a refrigerant for isothermal bags, comprising crosslinked sodium polyacrylate as a superabsorbent polymer, propylene glycol as a freezing-point-reducing agent and potable water. The inventive refrigerant is introduced into a container which is positioned together with an insulating polyethylene layer between two sheets forming a shopping bag, in order to perform two functions, namely: maintain the cold chain while frozen and fresh goods are being transported from the point of sale to the home, and prevent liquids from escaping in the event of a tear in the bag.
(ES) Producto refrigerante para bolsas isotérmicas compuesto por poliacrilato de sodio reticulado como polímero superabsorbente de líquidos, propilén glicol como reductor del punto de congelación y agua potable. Este producto se introduce en un envase que se coloca junto con una capa aislante de polietileno, entre las dos láminas que conforman una bolsa de la compra y cumple la doble misión de mantener la cadena de frío durante el transporte de productos congelados y frescos desde el punto de venta al domicilio y de evitar la salida de líquidos en caso de rotura de la bolsa.
(FR) L'invention concerne un produit réfrigérant pour sacs isothermes composés de polyacryle de sodium réticulé comme polymère superabsorbant de liquides, de propylène glycol comme réducteur du point de congélation et d'eau potable. Se produit est introduit dans un récipient qui se situe à proximité d'une couche isolante de polyéthylène, entre les deux couches qui forment un sac d'achat et accomplit la double mission de maintenir la chaîne du froid durant le transport de produits congelés et frais du point devant au domicile et d'éviter la sortie de liquides en cas de rupture du sac.
