Export-Ready Retainer Bulkheads Built for Performance
Production Packaging Innovations supplies IP-protected retainer bulkheads designed for fast, safe, and reliable bulk commodity export. Their contour-hugging design moulds to the container walls, improving sealing, retention, and overall loading performance. Lightweight construction allows simple single-person installation, helping reduce manual handling issues.
Built for Strength, Simplicity & Efficiency
Our retainer bulkheads eliminate common door-closure problems thanks to their high rigidity and superior strength. The latest No-Cut models further improve installation time and sealing accuracy, eliminating the need to cut around lugs or make awkward adjustments. Unloading is straightforward: simply cut the cardboard as required and remove.
Applications
Our retainer bulkheads suit a wide range of bulk commodities and export requirements. The design provides strong sealing, easier door closure, and a cleaner, more efficient workflow. Multiple configurations and No-Cut sets allow operators to select the right fit for their commodity and container type.
Types of Retainer Bulkheads
Single Door
Lightweight at approximately 8 kg, this model includes adjustable support beams, pre-notched side-wall features to avoid channel lugs, and sealing flaps for both the floor and walls. No cutting is required during installation, allowing for fast setup and stronger sealing performance.
Double Door
Double-door bulkheads retain bulk product without contacting the container doors and are made to size with no preparation required. Easy for one person to install, it features movable bars with options for two or three bars suitable for cotton seed, bone & poultry meal or four bars grain and heavier commodities.
Custom Bulkheads
Custom bulkhead solutions can also be developed for specialised requirements, including left-hand door seal inserts, retainer door clips, and more. The PPI Solutions & Development Team can engineer solutions to suit various commodity types and export conditions.
Retainer Liners
Manufactured from food-grade material and ideal for grain export, our retainer liners provide an economical solution to the shortage of food-grade shipping containers. They install quickly, reduce return-container costs, and pair perfectly with our patented bulkheads. Available in pallet lots of 50.
Container Desicants
Pro-Ex Gel Desiccants are designed to control moisture inside shipping containers. Made with calcium chloride and starch, they absorb up to 3 litres of moisture and traps it in a leak-proof gel. A slim profile and built-in hanging hook make installation easy without sacrificing cargo space.

Client Testimonials
Switching to the ‘no cut’ boards has been an absolute game-changer for our operations. Gone are the days of constant cutting and the inevitable mess that came with it. These boards have not only saved us an incredible amount of time but have also drastically reduced spillage. It’s now a rare occurrence that we even need to pick up a saw to trim anything down. Our workflow has become smoother, more efficient, and cleaner thanks to these.”
— Tim Ladlow – Riordan Grain Services

The new bulkheads are lightweight and we’re able to reduce a two-person job down to one.”
