Isothermal boxes for the transport and storage of all types of products and goods that require temperature-controlled logistics.


We manufacture and market a wide range of isothermal packaging and boxes in different sizes, materials and thicknesses to always offer the most suitable solution.

Isothermal packaging is a crucial aspect in ensuring the safety of products requiring a cold chain. These packages are designed to maintain a constant temperature during transport and storage of the products, avoiding sudden changes in temperature that could affect the quality and safety of the pipelines.

At Tecnisample we have a permanent stock of all products for immediate delivery. We can also make customised isothermal packaging for special needs.

Isothermal 100% recyclable

Ecombox caja isotérmica reciclable de Tecnisample

Sustainable isothermal packaging solution for the temperature-controlled shipment of perishable and sensitive products with maximum guarantees.

Its interior constructed with layers of thermal insulation, using 100% recycled kraft paper and cardboard, provides thermal efficiencies similar to polystyrene (EPS).


  • Foldable
  • Easy to assemble
  • Environmentally friendly and 100% recyclable
  • Insulation without plastic derivatives.
  • Customisable


  • 24-48 hours shelf life.
  • Refrigerated temperature range +2ºC +8ºC
  • Certified according to ISTA 7D

EPS Boxes
(Expanded Polystyrene)

EPS boxes, made of expanded polystyrene, in various sizes for use with cold accumulators or dry ice, depending on the desired temperature range.

Porexpan is a very light synthetic material, which is used intensively in packaging.


  • Unrivalled performance in terms of cushioning, insulation and protection.
  • Good thermal performance.


  • Different models and sizes.
  • Box capacities from 1.5 L to 79 L.
  • Thicknesses from 13 mm to 54 mm.

(polyurethane) enclosures

Embalaje isotérmico de poliuretano ISOPUR

Isothermal boxes, made of polyurethane foam, with a high insulating capacity due to its low thermal conductivity.

Solid, uniform and strong material structure.


  • Reusable
  • Highly impact resistant.


  • Thicknesses between 30 and 80 mm.
  • Made to measure.
  • Can be used with:
    • Positive cold accumulators
    • Negative cold accumulators

Dry ice, to maintain negative temperatures, guaranteeing the cold chain for more than 168 hours of transit.

Isothermal packaging solutions

Isothermal boxes for the transport and storage of all types of products and goods that require temperature-controlled logistics.

Isothermal boxes

Cajas isotérmica reutilizable ISOBIOTEC

Highly resistant hard plastic outer box, suitable for the transport of medicines and dangerous goods at controlled temperatures.


  • High resistance.

Homologation UN3373

Isothermal pallets

Palets isotérmicos CISO

Insulated container + plastic pallet (included). High-capacity insulated packaging for shipments requiring controlled temperature.

Optimal logistics solution for circuits where cold chain transport is not possible or cost-effective.


  • Highly resistant.
  • Reusable.


  • Can be used in combination with:
  • Eutectic plates for refrigerated products, or
  • Dry ice for frozen products

Isothermal boxes
with VIP panels

Friobox Return - Sobreembalaje isotérmico reutilizable para el sector biomédico

Isothermal box with VIP panels. Ideal for the shipment of high value materials, which require very strict temperature control.

The thermal conductivity of VIP honeycombs at room temperature is 0.00036 W / m K. This is approximately 10 times lower than expanded polystyrene.


  • Enables a huge reduction in packaging volume and weight.
  • Savings in transport, space and the number of accumulators to be used.
  • Transits from 24 to 140 hours.

Temperature ranges:

  • 2ºC 8ºC
  • 15ºC 25ºC
  • -18ºC -21ºC

Isothermal boxes approved for the transport of hazardous goods

Within our range of VIP products, we have isothermal packaging approved by the United Nations (UN).

Designed for the transport of hazardous products that require refrigeration or freezing temperatures during transport, they are complemented by the use of cold accumulators or dry ice.

Suitable for different UN and groups and also for various temperature ranges (positive or negative), this design adapted to the needs of sectors such as Pharmaceutical, Veterinary or Aeronautical Engineering, among others, was created to offer a quality solution that guarantees transport in exceptional temperature conditions, complying with IATA regulations for air transport, or with ADR land transport.

Its insulating interior made of high-density expanded polyurethane foam offers, in addition to an excellent insulating capacity, extra resistance compared to other insulating materials on the market that degrade quickly.

Unlike active cold, these composite designs are designed to offer the most select sectors passive travel independence, allowing the regular transport of very specific products, of great economic value or even with a limited life span.
