An inflatable, conformable, cushioning, packaging product (11) comprises a plurality of individual inflatable strips (21) of multiple bubble cushioning structures. Each individual inflatable strip (21) has a plurality of bubble chambers (23) with each bubble chamber (23) interconnected to an adjacent bubble chamber (23) by an interconnecting passageways (25) which is smaller in size and internal volume than the bubble chambers (23), but which is sufficiently large to enable air volume and pressure in one inflated bubble chamber (23) to be transmitted to adjacent bubble chambers (23) for distributing a shock load on one bubble chamber (23) along the entire length of the individual inflatable strip (21) of interconnected bubble chambers (23). Each individual inflatable strip (21) is defined between two laterally extending spaced apart peripheral seal lines (43) which have an undulating configuration free of corner shapes which could concentrated stresses.
L'invention concerne un produit d'emballage (11) gonflable, conformable, et matelassé comprenant une pluralité de bandes individuelles (21) gonflables dotées de multiple structures matelassées à bulles. Chaque bande individuelle (21) gonflable comprend une pluralité de bulles (23), chacune d'elle (23) étant interconnectée à une bulle (23) adjacente à l'aide de passage d'interconnexion (25) de taille et de volume d'air intérieur plus petits que les bulles (23), mais suffisamment grands pour permettre le transfert du volume d'air et de la pression de l'une des bulles (23) gonflables aux bulles (23) adjacente, afin de répartir une charge de choc d'une bulle (23) sur la totalité de la longueur de la bande individuelle (21) gonflable de bulles (23). Chaque bande individuelle (21) gonflable est définie entre deux lignes de scellement (43) périphériques espacées et s'étendant latéralement qui présentent une configuration ondulée exempte de coins qui pourraient concentrer des contraintes.
