In many manufacturing processes in modern industry, the sterility of packaging, raw materials and materials is essential to ensure reproducible results as well as the quality and safety of the end products. Various processes can be used to sterilise packaging materials. Beta-Gamma-Service GmbH (BGS) focuses in particular on ionising radiation and advises customers on the most suitable technology.<\/strong><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The trend in the manufacture of cosmetic products and foodstuffs towards the avoidance of preservatives also makes effective sterilisation necessary. Blasting treatment has become established for the rapid and cost-effective throughput of large quantities of packaging material: Through a Treatment with beta, gamma or X-rays<\/strong> plastic packaging such as bag-in-box systems (bib), inliners, flexitanks or ampoules, bags, bottles, cans and tubes can be sterilised so that they do not microbially contaminate the product to be packaged. Pathogens such as salmonella in particular are efficiently eliminated even at low irradiation doses of 15 kGy. \u201eWe also irradiate closures as well as exhaust valves and limiters such as sliding levers - all in the transport packaging<\/strong>. We never open the boxes,\u201d explains Barbara Schmitz, an expert in sterilisation and disinfection using radiation at BGS<\/a>, the process.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Various processes and technologies are available for disinfection and sterilisation. If sterilisation is established as an outsourced process, treatment with beta and gamma rays is one of the most common technologies. Particularly common is the use of sterilised with gamma rays, and increasingly also with electron beams. X-ray irradiation (X-ray) is at an early stage of development<\/strong>.<\/p>

Radiation sterilisation is the only process, Sterilise products in the sealed end-of-line packaging without significantly increasing the temperature<\/strong> and without the use of chemicals. Another advantage of radiation sterilisation is the reliable penetration of the materials.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Electron radiation has a high dose rate and a limited penetration depth, whereas gamma radiation has a high penetration depth and a relatively low dose rate. Electron beams are characterised by their ability to, irradiate individual packages within a few seconds<\/strong>. In contrast, irradiation in gamma systems takes several hours. Due to their high penetration depth, gamma rays are able to penetrate entire pallets or containers. \u201eThe products to be irradiated can usually be guided through the irradiation process directly on the delivery pallets,\u201c explains Barbara Schmitz. \u201eThe blasting used creates no radioactivity for physical reasons<\/strong>.\"<\/p>
