The future of corrugated board

Corcel Produce Cartons

Corcel single piece apple box

 

Commonly, Z-pack cartons are used for packing pip fruit - these consist of separate inner and outer box sections (i.e. base + lid)which slide one over the other in a complementary fit.


The total cardboard used in such a carton is 1.25m² weighing 1617 grams. Z-packs have a number of limitations, including poor print surfaces, the use of conventional corrugated board which consists of many fluid conduits that allow moisture to penetrate into the heart of the boxes, and compromised strength. Unpacked, the base and lid takes up twice the space.


CORCEL apple boxes use a unique closed cell technology which blocks moisture penetration. The fact that the board itself is eight times stronger than ordinary cardboard in combination with its superior moisture resistance means, the CORCEL box is well suited to long exposure to cool room environments. The CORCEL box is also interlocking for secure pallet stacking and it only weighs 1124 grams - resulting in savings of 27% in materials. These savings in combination with the revolutionary 'green'technology used to make the cardboard make the boxes very attractive to any company wanting to reduce its carbon foot print. It's super flat surface and pre-printed liner also enhances branding and presentation.

Corcel kiwifruit carton

 

Kiwifruit cartons made from Corcel's 3C technology have many advantages over existing cartons. They are moisture resistant and approximately eight times stronger than conventional corrugated board cartons. The extra strength allows for air channels to be incorporated into the cartons which when stacked side by side form ventilation chimneys. Based on thermodynamic calculations these chimneys move 300 cubic metres of air per hour from the bottom out to the top of a pallet stack. This feature cools down fruit much faster and reduces spoilage.

 

This CORCEL carton is made from 510 grams of paper. Again these cartons are excellent for cool store environments, and with a pre-printed liner will add value to branding and presentation.
