A process is presented for fabricating composite bodies of thermoplastic material including a foamed core bonded to a compatible thermoplastic sheet. A sheet of thermoplastic material is first preheated and then thermoformed on a first half-mould. The first half-mould with the thermoformed sheet is positioned opposite a second half-mould to form a hollow chamber therebetween. A foamable thermoplastic material containing one or more liquid hydrocarbons is injected into the hollow space at a temperature sufficiently high to permit the foamable material to expand and bond to the thermoformed sheet.

Containers, which are impervious to hydrocarbon vapors, in particular to fuel vapors, and comprise an outer shell of plastic material, which is coated with a polyamide layer at least on the surface in contact with the fuel. Said containers are used in the sector of the fuel industry, in particular in the automotive industry, as tanks for automobiles and motor vehicles.

Hydrocarbon vapor-impervious containers and process for producing them

A process for producing bodies of polymeric material having an outer shell and a core of foamed material is disclosed. The process includes the steps of: providing a mold having a pair of separable half-molds arranged facing each other; extruding a tubular thermoplastic parison between the half-molds; closing the half-molds around the parison, thereby defining a hollow space between the parison and walls of the mold; injecting into the inside of the parison a thermoplastic polymeric material admixed with a physical blowing agent, the parison expanding into contact with the walls of the mold, and conforming to the shape of the mold; and removing the article form the mold.

Multilayer and multifunctional packaging elements having a high-absorption activity toward aqueous liquid substances as well as barrier properties toward gases such as oxygen and carbon dioxide are prepared by thermoforming. The packaging elements includes an inner porous layer, an intermediate absorbing layer and an outer sheet having high barrier properties toward gases. The intermediate layer may contain anti-bacterial agents.

an apparatus for producing bodies of polymeric material having an outer shell and a core of foamed material is disclosed. The apparatus includes an extruder and accumulation chamber for extruding a tubular element, i.e., a parison, and a second extruder and accumulation chamber for injecting a foamable polymeric material for forming the core of the body inside the parison. The injection occurs inside the walls of a mold, which causes the tubular parison to undergo swelling due to the expansion of the foamable material until the parison conforms to the shape of the mold.

Apparatus for manufacturing bodies of polymeric material having a core

A die for co-extruding structural shapes is provided with a central cylindrical duct through which the molten polymeric material destined to constitute the central core of the structural shape flows, and a conical gap, coaxial with the central duct, into which the polymeric coating material is fed which will constitute the outer skin of the structural shape.
