The systems for processing and preserving products, such as tomatoes, vegetables and legumes, tuna, meat, jams and baby food are located in environments that are very humid and subject to constant temperature fluctuations. Zanasi inkjet marking systems are designed with high standards of protection, suitable for canning and bottling departments and intensive seasonal processing.
In addition, long-life products are subject to heat sterilisation process to maintain the nutritional properties and increase shelf life, i.e. the period of time for which the food product can be safely sold. Thermochromic ink specially formulated by Zanasi to produce codes on materials subject to sterilisation is used to provide quality control indications through the colour change of the ink, which means that the thermal treatment has been carried out in the phase of hermetic packaging.
Zanasi inkjet systems are extremely flexible for marking numerous types of containers with flat, curved, even and uneven surfaces. The versatility of the printhead allows it to be positioned in different points on the production line to clearly code the production data on the side or base of cans made of tin, glass or other materials.
