MATERIAL: POLYPROPYLENE AT ITS BEST
POLYPROPYLENE FOR FOOD PRODUCTS
Top quality polypropylene is a non-toxic, odourless plastic resistant to solvents and acids. It can be washed and sterilised and is water-resistant and non-hygroscopic. Its chemical and mechanical properties make it perfect for the manufacture of boxes and containers, which are ideal for handling in automatic warehouses.
In the food sector, we have gained certification for food products with regard to the master that can be submitted to a metal detector. This ensures the ability to identify a plastic chip inside a packed food container, which was previously in direct contact with the box. This allows us to discard the package before shipping.In the food sector, we have gained certification for food products with regard to the master that can be submitted to a metal detector.

Polypropylene 5A is a compound obtained by blending top quality polypropylene with a percentage of polypropylene from selected recycled post-industrial material. This raw material allows to achieve high levels of mechanical performance in automated warehouses.
FIREPROOF POLYPROPYLENE – CLASS V0
The fireproof polypropylene, available in different colours, ensures the prevention of the risk of fire in the automatic warehouse, a valid alternative where it is not possible to use traditional sprinkler fire-fighting systems.
AT THE CENTRE OF OUR ATTENTION
MATERIAL CHARACTERISATION DEPARTMENT. When materials arrive at our company, the first thing they encounter are our laboratories. Each new arrival is carefully checked and certified according to our strict quality standards, with composition tests and mechanical, thermal and functional tests. Only materials that pass these tests are placed in our silos. When the products have been moulded and the plastic has stabilised, this is the time for further tests: bottom bending and box structure resilience. Only after this process takes place products are released from the plant and sent to customers. Quando il prodotto è stampato e la plastica stabilizzata, è il momento di ulteriori test: flessione del fondo e resilienza sulla struttura delle cassette. Solo a quel punto può lasciare lo stabilimento ed essere inviato al cliente.
MELT FLOW TESTER This is a testing machine that determines the Melt Flow Rate of plastic, in other words the fluidity properties of the raw material in accordance with ASTM and ISO international standards. This value is extremely important during the raw material transformation phase, because thermoplastic materials are processed under pressure and at a certain temperature. The ability of these melted materials to flow under pressure at a certain temperature is essential to the science and technology behind polymers.
TRACTION TEST During the product design phase, we need to optimise the usage of materials to create items that are strong, but also light and rigid at the same time. Two of the reference properties are elasticity and resistance to traction. The traction test is carried out using two vices that secure the extremities of specifically-shaped test pieces and subject them to traction. The test result is a value indicating the breakage or yield load of the raw material. When suitably measured with an extensometer, the test piece also provides the traction elasticity module. The machine is designed to carry out tests on a wide range of test pieces in accordance with ASTM and ISO international standards.
IMPACT TEST WITH PENDULUM For users of the materials, impact resistance is one of the most important properties. It provides an efficient assessment of the cost/performance ratio during product development and quality control. Because components might yield when subjected to a force that is lesser than the critical breakage force, it is necessary to accurately determine the propagation of fractures following an impact. The pendulum machine is designed to carry out Charpy and Izod type tests on a wide range of test pieces in accordance with ASTM and ISO international standards.
18 INJECTION MOULDS OPERATING ON 3 SHIFTS.
From moulding small parts to boxes sized 800 x 600 mm. The moulds are designed for the application of labels with an IML In-Mould Labelling system. This is used both for customisation and the application of barcodes, on-machine weighing and tolerance testing.
The mixture of various “grains” and colours is heated until a homogeneous and mouldable paste is achieved. This is then inserted into the mould to create a product in the desired shape: a box, a finishing element or a mechanical part. The presses and moulds are connected via silos, rollers, testing positions, technical and commercial information systems making up the company’s control and value chain. At the end of the process each product is tested and checked to ensure that there are no imperfections. The product is delivered to the customer only if just perfect.
