Aseptic transfer technology Benefits and Advantages

Double Membrane TechnologyThe hermetically sealed membranes provide ‘tamper evident’ protection, before and after filling.The double membranes also maintain the high barrier properties of the entire package.

Before FillingTop membrane completely sealed. Internal membrane partially sealed.

During FillingInternal membrane is completely heat-sealed to the gland from below.

After FillingInternal membrane is fully sealed, providing tamper-evidence for the filled pack.

The Intasept® 2200 series is part of Rapak™ portfolio of cost effective, and environmentally-friendly packaging alternatives for liquids. Rapak’s filling systems include manual, semi-automatic and fully automated multi-heads for filling fresh and stable or sensitive liquids.

Rapak is part of DS Smith, Plastics Division and a world leader in liquid packaging, filling systems, and supplier to leading beverage companies worldwide.

Step by step fill valve principles

• Heat-sealed into the barrier bag wall is a 16mm or 32mm Intasept® gland (filling port).

• The aseptic gland features two laminated barrier membranes.

• One membrane is sealed across the top of the gland, and a second, internal membrane is partially sealed across the bottom of the gland.

• The bag and gland are then supplied sterilised, ready for filling.

• The Intasept® system provides interface sterilisation, filling and resealing without removing the bag from the filling head. At no time during the filling cycle is the product exposed to any potential contamination.

Unique double membrane

Product protection during filling via a completed sealed transfer system

Hermetically sealed, pre-fill and post-fill assuring product sterility - no clean room required

Advanced and innovative aseptic transfer technology

Aseptic bag-in-box filling

Steam SterilisationThe filling interface and the outer surface of the top membrane are steam sterilised at a high temperature.

Piercing the Membrane The top membrane is pierced by a forward stroke of the fill plunger.

FillingSterile product flows through the filling head and into the bag past the partially sealed internal membrane on the bottom of the gland.

Sealing and Flushing The internal membrane is completely heat-sealed to the gland from below, but does not fuse to the bag itself. The gland is steam flushed before the bag is released.
