A corrugated master carton is the export-grade outer box that holds the primary packs — PP bags, vacuum/nitrogen tins, or retail pouches — for shipment and storage. Cashew Tech sources and specifies these cartons to match a processor’s chosen primary pack.
The ply grade sets the strength: 3-ply for lighter loads, 5-ply as the common export standard, and 7-ply for heavy or long-haul consignments — chosen for burst strength and edge-crush resistance so kernels arrive unbroken.
3-ply, 5-ply & 7-ply explained
| Ply | Typical use | Relative strength | Best for |
|---|---|---|---|
| 3-ply | Light or inner packs | Lower | Short-haul, small units |
| 5-ply | Standard export cartons | Medium | Most kernel exports |
| 7-ply | Heavy or long-haul | High | Bulk or rough-transit consignments |
Burst strength & edge-crush for export
Burst strength (resistance to puncture) and edge-crush test (ECT, resistance to stacking load) determine how a carton survives palletising and container movement. Target values are set to your route and stacking height and confirmed per order — no figures are guessed.
What goes inside
Cartons hold your primary pack: 25/50 lb PP bags, vacuum tins, or retail pouches. A common configuration is two units per carton — for example two 22.68 kg tins, roughly 45.36 kg — though the exact fit depends on your pack and is confirmed per order.
Sizing, print & HS-code marking
Boxes can carry brand print, labelling and HS-code marking for customs — see the cashew kernels HS code reference. Board GSM, flute type and print MOQ are confirmed per order.
What Cashew Tech sources & specifies
Cashew Tech specifies ply, burst strength, sizing and print to match your primary pack and destination, and supplies the cartons with your line. For the packing process and machine, see the cashew packing guide and the vacuum packing machine.
