ASM has designed a patented 2-compartment system for products without preservatives. The separation of the propellant and the contents has a lot of advantages and allows the use of compressed air or nitrogen as a propellant. MicroCOMPACK | The world’s smallest 2-compartment system for 5-15 ml capacity, eveloped and patented by ASM. Particularly convenient for pharmaceutical products, creams, emulsions, gels, pastes, and solutions | Propellants: all commercially available liquefied gases, compressed air or nitrogen | Absolutely diffusion-free aluminium collapsible pouches coated on the inside | Operable at all angles. AluCOMPACK | For 15-75 ml capacity | Uses and benefits identical to MicroCOMPACK. COMPACK | Pressurised gas system for special corrosive and extra-sensitive products | Standard aerosol cans for 150 ml capacity | Propellants: compressed air, nitrogen or CO2 | Contents are completely enclosed in a polyethylene pouch, and free of metal contact | Operable from all angles, optimal evacuation. LamiPACK | Aluminium or tinplate | 50-300 ml capacity | Dispensing according to packaging size; e.g. 300 ml = up to 99% | Propellant: compressed air, nitrogen or liquefied gas | Multi-layered laminated pouch fixed to a standard valve | Film with protective barrier layer. ASM also has the necessary filling systems for additional 2-compartment systems, e.g. Bi-Can, Presspack, Exxel and Airless.
