• Material made 100% from waste collected from beaches and hillsides from the We Nature Project;
16 Reasons
ENVIRONMENTALLY-FRIENDLY
Core Case products are manufactured with 100% recycled materials.
MORE DURABLE
Plastic has a longer shelf life comparing to wooden boxes, especially if properly stored;
ERGONOMIC AND SAFE
Integrated handles for better handling. Rounded corners: greater safety instacking. Rigid material: no twisting of the box;
NO RISK OF CONTAMINATION
Plastic is an inert material that does not react chemically with other substances; Core Case boxes have holes for water drainage avoiding contamination with the box tacked below;
DATA AND INFORMATION SECURITY
Fitted ID plates, surfaces with a rough texture to preserve the written data, lid with efficient closing and locking system;
GREAT RESISTANCE TO IMPACT AND EXTREME TEMPERATURES
Products tested in laboratory and field trials (exposed to temperatures from -40º to 50ºC);
STANDARD PRODUCTS AND INDUSTRIAL SCALE PRODUCTION
Products are made in an ISO 9001 certified plant. Boxes are not hand-crafted as wooden boxes: higher productivity, consistency and guaranteed delivery time;
EFFICIENT USE OF SPACE
Core Case products considerably improve the organization of warehouses and storage places reducing the need for high investment in infrastructure. Greater stacking capacity;
THE DESIGNS ARE MADE BY INDUSTRY EXPERTS
All products were developed by a design team under the direct supervision of a geologist with over 12 years of experience in mining science and technology development;
ECONOMICAL TRANSPORT
Core Case plastic boxes are lighter than wood which significantly reduce cost during transportation;
COST-EFFECTIVE
Studies have shown that in the mid and long term use, Core Case products are extremely cost-effective has compared to other materials (wood, cardboard, metal).
NO MAGNETIC INTERFERENCE
Our plastic cases have nothing that would effect samples susceptible to magnetic interference. They contain no metal parts, unlike for example the nails used in wooden cases.
FLAMMABILITY
Core Case products were subjected to flammability tests and met the requirements specified in the reference standard ASTM D 635: 2018. That is, they present less risk of fire when compared to cardboard and wood boxes.

FAQ
All types of plastic, including PP, are degraded if left exposed for a long time outdoors. However, currently there are UV protection stabilizers (available as optional items for Core Case products) that can be added to the raw materials used to manufacture plastic boxes. These substances protect the boxes and allow them to resist adverse weather conditions for a longer period. In any case, we do not recommend leaving the core sample boxes outside, regardless of the material from which they are made (metal, wood, plastic or other material), since such exposure may change the characteristics of the boxes and even the samples.
No, as they have holes in the form of drains between each partition wall, in order to avoid the accumulation of water.
Plastic durability has always been the subject of many discussions. However, we estimate a durability of over 20 years, if the boxes are properly stored (in covered warehouses, in order to avoid exposure to adverse weather conditions and with a compartment for each box). If the boxes are stacked up on top of each other for a long period, shorter durability is expected (about 5 years). This is especially true at the base of the stack (first two boxes), where the pressure exerted is greatest, and ruptures and/or cracks may occur in the corners of the boxes. This process should be accelerated even more if the boxes are exposed to the sun and do not have a UV stabilizer in their composition.
The plastic cases are manufactured with an inert material (polypropylene – PP); therefore, they are not harmed by cleaning detergents and HCl, which are commonly used by geologists during the description of the core samples.
Yes, several tests and simulations have been carried out (tensile, bend, tension, impact and hardness tests) focusing on the storage and stacking capacity, resistance and durability of plastic boxes. However, when it comes to duration, this estimate is difficult to specify, as it depends on the culture of the company/user in relation to the manner of use.
People must bear in mind that the boxes cannot be handled by the flaps or in a careless way, nor can they be tossed in the vehicle bed without any concern for their integrity.
As for the measures, they follow the exact same dimensions of the NQ2, HQ and BQ wooden boxes (in the future), aiming at meeting the standards of Brazilian and foreign companies.
Although it is possible to make almost anything out of plastic nowadays, tag holder with fitting from top to bottom would imply a technical difficulty when making the mold due to the extraction direction of the piece. Not that it is impossible to do so; in fact, there is a possibility. But this would require greater investment in tools (molds), in addition to possibly weakening the structure of the mold. It would also require a larger injection press during the manufacture of the boxes, due not only to the larger size of the mold but also to its weight. Therefore, for technical and economic reasons, we decided to make the tag holder this way. In order solve the question of the tag falling, we suggest the use of metal fasteners (rivets, for instance) or high-performance adhesives (Araldite, for instance). Another alternative would be to manufacture high-adhesion adhesives to enter data and customized information, according to the user’s needs.
The internal partition walls of the plastic boxes are corrugated in order to homogeneously distribute their weight when they are stacked, thus contributing to their resistance and durability. Moreover, the corrugated partition walls facilitate the grip when removing cores during measurement, description and sampling activities.
