(EN) PROCESS FOR HEAT SEALING PACKAGES AND MATERIALS USABLE IN SAID PROCESS

Abrégé
(EN)
A sealing process for producing clean, contamination-free seals. The process includes the step of incorporating a small amount of polar liquid within the material (12) to be sealed between heat-sealable layers (14, 16). An alternating electromagnetic energy field, such as that produced by a dielectric heating device (18), is applied to the seal area (24). The energy vaporizes the polar liquid, thereby cleaning the seal area (24). Subsequently, the energy causes the resinous layers (14, 16) to seal together, sealing the material (12) within the package. A preferred composition for sealing within the resinous package is also disclosed. The material includes a polar liquid, a surfactant, wax, oil and microbeads. The material is especially suited for producing padding devices.

Procédé de scellement permettant de produire des scellements propres sans contamination. Le procédé comprend une étape d'incorporation d'une petite quantité de liquide polaire à l'intérieur du matériau (12) à sceller, entre des couches thermosoudables (14, 16). L'on applique un champ d'énergie électromagnétique, tel que celui produit par un dispositif (18) de chauffage diélectrique, à la zone à sceller (24). L'énergie vaporise le liquide polaire, nettoyant ainsi la zone de scellement (24). Par la suite, l'énergie provoque le scellement des couches (14, 16) résineuses et le scellement du matériau (12) à l'intérieur de l'emballage. L'on décrit également une réalisation préférentielle permettant de réaliser le scellement à l'intérieur de l'emballage résineux. Le matériau comprend un liquide polaire, un agent de surface, de la cire, de l'huile et des microbilles. Le matériau convient particulièrement à la production de dispositifs de rembourrage.
