Due to the low weight, the strength of the material and the high degree of thermal stability, the isothermal boxes in PPE are used for products that need the temperature to be controlled and constant during storage or transport.
They can also be used as such, as boxes, but also placed in injected plastic boxes that give a superior resistance to friction or impact.
The most common uses are:
- the placing of food-type food or drink-type products, raw or prepared, which must be maintained within certain temperature ranges; are used by companies from the HoReCa domain, food deliveries at home or street, deliveries to smaller retail stores or even mini market type, etc.;
- various products in the medical area (from vaccines or drugs and laboratory preparations, to biological samples for analysis);
- industrial or production area (samples that may degrade due to improper temperatures, or products that are intended to operate only under certain thermal conditions and that can be disturbed if maintained in other conditions, etc.), and even applications in the military area.
Besides the advantage of maintaining the temperature inside, these boxes are very light because EPP is a light foam, and this entails low transport costs (turn and return).
Even if it is light, the PPE foam is very resistant having a very high density, which also gives it the role of protecting the physical integrity of the products against shocks or vibrations, even more so in situations where the boxes are used as such and are not placed in another outer packaging.
Also, the closed structure of the cells provides a high degree of hygiene to these boxes because they can be washed / cleaned / sanitize even at the industrial washing machine, but does not allow the development of molds and fungi, or the deposition of dust.
They can be produced in a wide range of models and colors, with or without partitions, with vertical or horizontal use, with lid or without lid (if they are put in another container with a separate lid), with labels, logo or other imprints, they can have handles for ergonomic handling.
The insulating boxes in PPE are reusable, 100% recyclable, have no odor, are environmentally friendly, are water resistant, have a long service life.
Technical components of the EPP
The extraordinary qualities of the PPE foam (shock resistance, high degree of thermal and acoustic insulation, moisture resistance, possibility of customization on the desired design, light weight) make it the right material for casting technological parts and components.
Thus, from EPP can be produced casings for hosting important components of heating systems, ventilation and air conditioning systems, such as: pumps, valves, boilers, different control mechanisms, heat exchangers, etc.
These components benefit from the insulating properties of EPP, by limiting and reducing heat loss, increasing the level of acoustic protection (especially in air conditioning units, pumps or compressors), low weight that does not put pressure on the elements and does not additionally require the installations in which they are placed.
A double advantage is that these technical components in EPP also function as a protective packaging for transport, absorbing shocks.
The assembly of technical components in the EPP is done very quickly, which means lower production costs, but also access to parts and fast maintenance.
Boxes with divisions
These boxes are used for parts that are fixed inside by means of these partitions.
They are returnable packaging, which due to the strength of the PPE foam, have multiple uses and can be used in the long term, thus reducing the costs of packaging. They can also be produced from material with ESD properties.
They are placed in large transport packages: injected boxes and containers, flat-mounted containers, they can also be placed as such on injected plastic pallets and covered with lids, forming a compact system.
They are used especially in automotive, for very sensitive parts, which also need anti-scratch packaging conditions in addition to anti-vibration or anti-glare packaging, but also for electronic parts and components, fragile instruments, measuring devices, precision equipment, certain types of electronic equipment (such as drones), expensive products, etc.
A plus is that this type of partitioning also allows the nesting packaging of the products, meaning that the internal space of the box is used to the maximum without the products being affected in any way when packaging or transporting. This aspect attracts low transport costs, but also an optimized volume of deliveries.
