Title
(EN) PROCESS AND COMPOSITION FOR PROTECTING AND CUSHIONING PROTRUSIONS
(FR) PROCEDE ET COMPOSITION SERVANT A PROTEGER DES PARTIES PROTUBERANTES EN LES AMORTISSANT CONTRE LES CHOCS
Abstract
(EN)
A process for packaging a product, particularly one with sharp protrusions such as cuts of meat, a composition for cushioning the sharp protrusions during packaging and shipping and a foamed material prepared therefrom, the process including the steps of applying a foamed composition to the product to be packaged, and encasing the product in an outer package. The foamed material can be applied in liquid or semi-liquid form at a point-of-contact temperature less than about 130 °F with solidification occuring substantially on contact. The foamed material is, preferably, applied selectively to cover the sharp protrusions and contains a chemical substrate which includes a polymer selected from the group consisting of polyethylene, ethylene vinyl acetate and mixtures thereof, an aliphatic hydrocarbon and an antioxidant stabilizer. A suitable gas is encapsulated within the chemical substrate.
(FR)
Procédé d'emballage d'un produit, en particulier un produit comportant des parties protubérantes à angles saillants tel que des découpes de carcasses de boucherie, composition servant à protéger les parties protubérantes au cours de l'emballage et de l'expédition, et matériau expansé préparé à partir de cette composition. Le procédé consiste à appliquer une composition expansée au produit devant être emballé et à envelopper le produit dans un emballage externe. Le matériau expansé peut être appliqué sous forme liquide ou semi-liquide à une température de point de contact inférieure à 130 °F environ, la solidification se produisant pratiquement au moment du contact. Le matériau expansé est de préférence appliqué sélectivement de façon à couvrir les parties saillantes aigües, et contient un substrat chimique qui comprend un polymère choisi dans le groupe composé de polyéthylène, de copolymère éthylène/acétate de vinyle et de mélanges de ceux-ci, un hydrocarbure aliphatique et un stabilisant antioxydant. Un gaz approprié est encapsulé dans le substrat chimique.
