Brick-Pack Packaging in the Beverage Industry
Brick-pack (or brick-shaped carton) packaging is widely used for UHT milk, juice, liquid food, and other aseptic beverages. The term 'brick plant' in the used equipment market typically refers to the downstream packaging and palletising equipment that handles filled cartons — including tray formers, shrink wrappers, case packers, and palletisers configured for brick-pack carton products.
Typical Brick Plant Components
- Carton accumulators — buffer filled cartons between the filling machine and secondary packaging
- Tray formers — create corrugated trays for carton grouping
- Shrink wrappers — apply shrink film over carton groups or tray-and-film combinations
- Case packers — pack cartons into corrugated cases
- Straw applicators — attach drinking straws to individual cartons
- Palletisers — stack finished cases or trays onto pallets
Critical Inspection Points
- Carton handling — brick-pack cartons require gentle handling to avoid seam damage
- Speed compatibility — all downstream equipment must match the filling machine output
- Format flexibility — different carton volumes (200ml to 1L) require different handling setups
- Straw applicator condition — if applicable, check adhesive system and straw feeding mechanism
- Integration with filling machine — downstream equipment must accept cartons from your specific filler
Common Issues
Problems to Watch For
- Carton damage from aggressive handling in conveyor transitions
- Straw applicator adhesive failures causing straw detachment on retail shelves
- Limited format flexibility when changing between different carton sizes
- Compatibility issues between downstream equipment and specific filling machine brands
Frequently asked questions
What is a brick plant in the used equipment market?
In the used machinery market, a 'brick plant' typically refers to the secondary packaging and palletising line configured for brick-shaped carton products. It includes all equipment from the filling machine discharge to the finished pallet.
Can brick plant equipment handle different carton sizes?
Most brick plant equipment can be adjusted for different carton volumes with mechanical changes and change parts. However, large format differences (e.g., 200ml to 1L) may require significant changeover time and tooling.
Is the filling machine included in a brick plant?
The filling machine (typically from manufacturers like Tetra Pak, SIG, or Elopak) may or may not be included. Used brick plant equipment is often sold separately from the filling machine. Verify exactly what is included in any listing.
