Saving on lids for pepper and aubergine packaging: significant savings in storage, logistics and costs
In the agriculture sector, packaging costs, efficiency and space usage are being more critical than ever. One surprisingly impactful area for cost reduction lies in a component that is often taken for granted: the pre-folded lid.
Many packers still use pre-folded lids to close trays for peppers, aubergines and other greenhouse products. Although familiar, these lids come with clear drawbacks: they require substantial storage space, costs more than plain blanks, and involve more manual handling. Switching to flat blanks, which are formed and closed directly in the line, offers an interesting alternative.
Why switch to blanks?
-
Less storage space & more efficient logistics
Because blanks are delivered flat, far more units fit on a single pallet compared to pre-folded lids. This allows companies to work with significantly fewer pallets, reducing internal logistics pressure. For businesses with limited storage space or those facing seasonal peaks in material demand, this offers immediate advantages.
-
Lower material costs
A blank is simpler to produce and requires less handling to produce, during transport and storage. As a result, the cost per unit is typically lower than that of a pre-folded lid. Packers working with large volumes often see a structural reduction in packaging material expenses.
-
Faster and more efficient packing
When blanks are automatically fed into the line and formed into a finished lid, much of the repetitive manual work disappears. This saving on lids reduces dependence on labour, a major benefit in seasonal periods when staff availability is limited and expensive.
-
A more sustainable choice
Because blanks take up less storage and transport volume, fewer transport movements are required. This reduces CO₂ emissions and contributes to a more sustainable supply chain.
Forming lids automatically: how to approach it?
To use blanks efficiently, a machine is required that can automatically form and place the lid. Such a solution must be compact, reliable and compatible with the common tray sizes used in the fresh produce industry.
Boix HAT MINI: Compact machine for automatic folding and gluing lids and place them on top of the box
For companies looking to adopt blanks, Boix developed the HAT MINI. This hotmelt lid-closing machine automatically forms and applies blanks onto trays, supporting the growing need for space savings, cost reduction and process optimisation.
Key features that allow savings on lids
- Compact footprint, ideal for tight packing areas or greenhouse environments
- Capacity up to 1,300 lids per hour to suits the seasonal peaks
- Compatible with various tray types, including Bliss boxes and C-1 trays
- Generous blanks storage of 1,5 meter long
- Easy glue parameter adjustments, ensuring optimal sealing quality across materials
A smart step towards more efficient packaging
Switching to blanks enables packers to reduce material usage, optimise storage and streamline logistics. With a compact and reliable solution like the HAT MINI, companies can realise these benefits without major changes to their existing packaging line.
