Polibox® Containers

Food and perishable items have very high conservation requirements. They must be maintained in a safe environment regarding health and hygiene. The other important requirement is the mechanical protection caused by the delivery of food products. And finally we have the temperature control. Today the need of HO.RE.CA. and catering companies is caring about ecological and environmental aspects. Our commitment has been and will be, in the coming years, to create product culture by promoting the reduction of environmental impact with our isothermal containers, as they are reusable, not disposable and above all 100% recyclable.

Expanded polypropylene

Expanded Polypropylene used in the production of Polibox® is an ecological material: it is composed of 98% air and is recyclable. The basic material is oil. For the production of EPP, the pearls (form in which the polypropylene is presented at the early step) are swelled up to 50 times their initial volume by putting them in contact with hot water steam and nothing else. Hence chlorofluorocarbons are used neither for production nor for processing. Therefore the EPP does not harm the environment neither for its productive effect nor as a raw material, as it consists of air and only 2% of pure hydrocarbon structural material.

CO2 reduction

For the production of Polibox® only first quality virgin EPP is used, environmentally friendly: without CFC, polyurethane foams or other expanding gases. The goal is to use materials that minimize the environmental impact of CO2 pollution.
CO2 reductions are the result of the ability to manufacture isothermal containers for foods that weigh up to 37,5% less.

100% recyclable

The EPP can be burned with other solid urban waste without producing poisonous or acid substances. The combustion gases are only CO2 and H2O. 1 kg of expanded polypropylene saves about 1.3 kg of naphtha in incinerator operation. You are allowed to dispose of the containers in normal landfills without affecting the environment, as the product is chemically neutral and does not pollute either the air or the aquifers. We can safely say that these manufactured goods, shredded with solid urban waste, made mostly of air, contribute to the decomposition of organic waste.

Technical features


Maximum tightness

The closed cell structure of EPP guarantees excellent isothermal qualities and confers excellent insulating qualities, from odors and liquids. Nothing can cross the structure of Polibox® containers, which thanks to the interlocking lids, become an excellent solution for large movements. Regarding Crystal containers, the internal surface is "crystallized", perfectly smooth and waterproof, complying with UNI 12571 standards.

Maximum lightness and strength

Sturdy, but light. Polibox® isothermal containers, thanks to the high density of closed cell expanded polypropylene, guarantees excellent resistance to mechanical stresses. This allows the container to be less heavy, which is restrained because EPP is made up of 98 % of air. Polibox® containers are extremely stable, absorb shocks and are scratch-proof. An excellent protection for your loads, even for the heaviest ones.


Polibox® is easy to handle, thanks to the lack of edges, combined with the lightness of expanded polypropylene and the comfortable lower ergonomic handles. The handles allow you to move and transport your contents in complete safety. The maintenance of Polibox® containers is very easy because industrial washing and disinfection with detergents and disinfectants, hot water and steam up to a temperature of 110° C.


Polibox® isothermal containers are the best solution for large movements. If you have to transport large quantities but in a small space, there is only one solution… Thanks to the smart space-saving stacking method, a safe and well-organized transport is guaranteed. If your core business is food distribution, you will find a faithful ally in the Porter containers, as they can be front-loaded, even when they are stacked.

LCA life cycle analysis of an isothermal container

In seguito alla collaborazione nata tra il Dipartimento di Scienze Agrarie e Ambientali dell’Università degli Studi di Milano e l’azienda SDS srl, si è valutato l’impatto ambientale del ciclo di vita di un contenitore isotermico Polibox. I contenitori Polibox sono ottenuti da polipropilene espanso (PPE). Un materiale atossico, leggero, resistente e 100% riciclabile. Non sono prodotti monouso, si possono utilizzare per movimentare alimenti caldi e freddi, sfusi o in Gastronorm. La sua composizione, 100% polipropilene espanso, permette di non usare altri materiali (come parti in metallo o in plastica) nella struttura del contenitore. Il contenitore Polibox è particolarmente utilizzato nei sistemi tradizionali di ristorazione collettiva. Il trasporto di Gastronorm 1/1 dalla cucina centralizzata alla sede satellite necessita di contenitori isotermici per garantire le caratteristiche termiche del prodotto. I vantaggi dei contenitori isotermici Polibox non sono solo a livello strutturale e di performance del contenitore ma portano vantaggi anche e soprattutto dal punto di vista logistico (contenitori più leggeri e impilabili).

Due to the collaboration between the Department of Agricultural and Environmental Sciences of the University of Milan and the company SDS srl, the environmental impact of the life cycle of a Polibox isothermal container was assessed. Polibox containers are made from expanded polypropylene (PPE). A non-toxic, light, resistant and 100% recyclable material. They are not disposable products, they can be used to handle hot and cold food, in bulk or in Gastronorm. Its composition, 100% expanded polypropylene, allows not to use other materials (such as metal or plastic parts) in the container structure. The Polibox container is particularly used in traditional collective catering systems. The transport of Gastronorm 1/1 from the centralized kitchen to the satellite location requires isothermal containers to guarantee the thermal characteristics of the product. The advantages of Polibox isothermal containers are not only at the structural and performance level but also and above all bring advantages from the logistic point of view (lighter and stackable containers).


What is the life cycle assessment (LCA)?

The term Life Cycle Assessment (LCA) identifies the main operational tool of "Life Cycle Thinking". An objective method to evaluate and quantify the energy and environmental loads and the potential impacts associated with a product, process or service, throughout its life cycle, from obtaining raw materials to disposal. At the base of the LCA methodology there are the ISO 14040: 2006 and ISO 14044: 2006 standards which define the fundamental steps for carrying out the analysis. The ISO standards establish the structure of the LCA and define 4 phases for its implementation:
Phase 1: Definition of the objective and the field of application
Phase 2: Inventory analysis (LCI Life cycle inventory)
Phase 3: Evaluation of the impacts (LCIA life cycle impact assessment)
Phase 4: Interpretation.

Polibox Green

- WEIGHT + PERFORMANCE = - 37.5% Co2

The advantages of using the Polibox container are not only in its production phase as the material used is expanded polypropylene. The main advantage is identified in the use phase. The reduced weight (85% less than traditional containers) leads to a reduction in load equal to 27%, which therefore leads to savings in fuel and consequently a reduction in emissions.

Most of the impacts demonstrated in positive percentages (therefore negative for the environment) are deriving from the extraction phase of the raw material or from the transformation phase for the production of Polibox. The only raw material used for the production of the Polibox containers is expanded polypropylene (PPE), a material of petrochemical origin and the molding phase requires the production of steam at high pressures. The impacts deriving from the molding phase are mainly linked to the gas extraction and combustion phase and to a lesser extent to the production of energy. Unlike other products on the market, Polibox isothermal containers are not composed of other raw materials other than expanded polypropylene. The impact deriving from the disposal of the Polibox has a very low incidence when compared with the entire life cycle. It must be emphasized that the Polibox container, being made up of 100% expanded polypropylene, is a 100% recyclable isothermal container.
