Title (EN) THIN ABSORBENT PADS FOR FOOD PRODUCTS
(FR) GARNITURES ABSORBANTES MINCES POUR PRODUITS ALIMENTAIRES
Abstract:
(EN) Thin absorbent food pads (10) with a bulk under 0.5 cm are provided having an insulation layer (12) and from 3 to 30 sheets (16) of compressed wet resilient cellulosic material wherein the absorbent pad (10) has an absorbent capacity of at least 10 grams fluid per gram absorbent material and which expands in volume by at least 50 %, relative to dry volume, upon wetting. The thin absorbent pads may be provided by calendering the insulation layer and cellulosic sheets under a force of about 100 to 1500 pounds per linear inch, thereby reducing the bulk of the pad by 30 to 60 % and creating a pad which will significantly expand upon wetting to achieve an aqueous absorbent capacity of about 0.85 grams fluid per square centimeter (5.5 g/square inch).
(FR) Garnitures absorbantes (10) minces pour produits alimentaires, d'une épaisseur inférieure à 0,5 cm, qui possèdent une couche d'isolation (12) et de 3 à 30 feuilles (16) de matière cellulosique comprimée dont le volume augmente lors de l'absorption de liquide. Ladite garniture absorbante (10) présente une capacité d'absorption d'au moins 10 grammes de fluide par gramme de matière absorbante et se dilate en volume d'au moins 50 %, par rapport au volume sec, lorsqu'elle est mouillée. Lesdites garnitures minces peuvent être obtenues par calandrage de la couche d'isolation et des feuilles de cellulose sous une force d'environ 100 à 1500 livres par pouce linéaire, ce qui réduit l'épaisseur de la garniture de 30 à 60 % et crée une garniture qui se dilatera considérablement au mouillage pour parvenir à une capacité d'absorption d'environ 0,85 gramme de fluide par centimètre carré.
