Wax Cardboard Core Boxes vs.
Discoverer Plastic Core Trays

Wax Cardboard Core Boxes:
An Introduction

Wax cardboard core boxes (or plastic corrugated core boxes, which have similar properties) are predominantly used in the USA, where the supply chain is very much established.

Cardboard core box


  • Easy to transport large amounts due to its flat pack nature – entire ‘drill hole’s worth’ can be taken to the rig
  • Lightweight material; one-person lift is possible
  • Comes with a lid and, along with it, a large flat area to write notes on


  • Can collapse when laden with heavy objects
  • Due to its flexible material, the dividers can slant when there’s core inside – not the perfect setup for imaging/scanning
  • Not good for humid or cold climates where moisture is predominant
  • Companies additionally invest in shed structure and shelving for storage
  • Being a shorter box than its peers, the core has to be broken more to fit into the box
  • Assembly before use is required


Cardboard boxes do the job they are intended to do. However, if assembling a core box is a new concept to you, we don’t recommend you start now with these cardboard wax core boxes.

Why try plastic core trays?

Plastic core trays are not new technology, but aside from having a proven track record of durability, it has evolved into more than a basic core sample container. More and more innovations are built into the plastic core tray that are eliminating entire sections of the downstream processes that in turn lead to savings in money and man-hours.


  • It’s been proven in high (140°F/60°C) and low (-58°F/-50°C) temperatures around the world
  • Designed to be stacked in pallets and left outside for the entire life of the mine
  • The expense of building a storage shed or having racking is completely removed
  • Chemically inert product, not susceptible to sulfide corrosion
  • Lightweight to carry
  • High-impact resistant and built to last
  • Not susceptible to termites or rotting
  • No need to DIY assemble the boxes on site


  • As they are not flat-pack, they can be a little bulkier, leading to higher transport costs
  • You are limited to the sizes the manufacturer offers, as the injection mold tooling is expensive to set up


With the Pros vastly outweighing the Cons, it’s no surprise that the plastic core tray is steadily becoming the most predominant form of storing and transporting core across the globe.
