At Boix, we keep improving our machines to meet real packaging challenges. That is why we have expanded the functionality of our MCT-1/TS Top Seal punnet machine with a new upgrade: the Double-Wall Kit. This kit allows you to fold an additional double wall on the canopy (ledge). As a result, the punnet becomes stronger and more durable, even in demanding supply chains.
This upgrade was developed together with a customer in the Netherlands. It was designed to support a patented punnet format. In addition, it helps brands protect products better while keeping packaging efficient and reliable.
Why a double wall matters in Top Seal packaging
Top Seal punnets often face high stress. They are stacked, transported, and handled at speed. For this reason, the canopy area can become a critical point. With the Double-Wall Kit, the long sides gain extra reinforcement. This improves stiffness and overall box integrity. It also supports better performance in automated handling and palletising.
Main advantages of the Double-Wall Kit
- Reinforced structure for greater stability during handling and stacking.
- Increased product protection throughout transport and storage.
- Reliable Hot-Melt sealing for a strong and consistent bond.
- Better performance with reinforced designs, without adding complexity for operators.

Built for efficiency: the MCT-1/TS platform
The MCT-1/TS is designed to form multiple types of Top Seal punnets. It is also built as a compact, double-head solution. This means it can work with two different designs at the same time, depending on the configuration.
In addition, official product documentation highlights key elements such as servo-controlled folding, Hot-Melt glue systems, and production output that can reach high speeds per head (depending on format and setup).
Therefore, adding the Double-Wall Kit is a natural next step. It extends the machine’s capability for brands that need extra strength in Top Seal punnets, especially in fresh produce and food packaging.
