When aluminium packaging is described as “monobloc”, this means that it is manufactured from a single piece of aluminium, with no welds on the body of the packaging.
This design, developed by Tournaire over several decades, meets an essential objective: to ensure the integrity of the packaging and contribute to the protection of the products it contains. Monobloc technology is also one of Tournaire’s historical areas of expertise, developed as part of an innovation and quality approach.
A seamless design to limit areas of weakness
Packaging manufactured from a single piece has no welds on its body. This absence of joints helps limit areas likely to become points of weakness, particularly with regard to the risks of leakage or cracking.
The monobloc structure thus helps preserve the integrity of the packaging throughout its use, storage and transport.
An inner surface suited to cleanliness requirements
Monobloc manufacturing also makes it possible to obtain a smooth inner surface with no roughness, limiting areas likely to retain residues.
At Tournaire, this design is combined with intensive washing to control the chemical, microbiological and particulate cleanliness of the packaging. This requirement is particularly important for sensitive products and applications requiring a high level of cleanliness.

A barrier to protect sensitive products
Aluminium naturally has barrier properties that help protect the contents against light, UV rays and gases. The monobloc design, combined with a suitable closure system, also contributes to the tightness of the packaging.
This control of packaging integrity relies in particular on Tournaire’s expertise in tightness.
The choice of packaging must also take into account the nature of the packaged product. Depending on the application, aluminium can be used bare or receive a suitable internal coating. Compatibility between the product and its packaging is therefore an essential factor in preserving the stability and properties of the contents.
Monobloc, a technology serving different applications
This technology is used in many sectors requiring high-performance packaging solutions: perfumery, pharmaceutical and veterinary, fine chemicals and specialties, food, beauty and well-being.
Among the solutions developed by Tournaire, OMNI PLUS® is a range of monobloc aluminium bottles designed in particular for the packaging, transport and storage of sensitive liquids. It is available in several capacities, from 50 ml to 6.25 L, and is UN certified.

Monobloc therefore does not simply mean “manufactured from a single piece”. This technology makes it possible to design seamless packaging while controlling essential criteria such as integrity, cleanliness, tightness and product protection.
Since 1833, Tournaire has been developing its expertise in packaging solutions for demanding products and materials. Monobloc aluminium technology remains one of its distinctive areas of expertise today.
