Abstract
Method for molding packaging materials with air bubbles, wherein said materials to be molded are constituted by at least one pair of sheets of low density polyethylene, intimately joined in superposition and with one of them carrying defined multiple protuberances forming said bubbles, characterized by successively comprising the steps of subjecting the cold material to the action of a compression mold but under limits that determine its natural adaptation to the profile of the forming space that mediates between the male and female parts constituting said mold and do not involve the destruction of air bubbles; supplying a stream of hot air through at least one of the constituent parts of the mold and directly towards the areas of the material which are mostly deformable, such as curvature and ribs; interrupting the supply of heat when the material reaches its corresponding softening throughout its thickness; allow the material contained inside the mold to cool; proceed to open the latter and remove the formed material.
