Whether it’s paint buckets, oil cannisters or cleaning agents, the packaging for chemical products comes in a wide variety of formats, is often irregular, and is used in a range of application-specific ways. It can be quite difficult to apply labels to their surfaces, as this must often take place in dusty or moist environments. Labeling systems must be able to avoid errors and provide documentation while also meeting demanding requirements for precision and speed – there must be no interruptions in the labeling process. Chemical production systems often run year round, twenty-four hours a day. The packaging and labeling lines downstream of the production area also have to run for this long, and often at high speed. Furthermore, the processes have to meet the extremely wide range of labeling requirements for chemical products, as the industry is subject to strict legal regulations. For example, illegible or detached labels can cause consumers to mistake the contents of a container, which can have drastic consequences for people and the environment.
Whether it’s tamper-evident strips, booklet labels or any other common label type: The modular design of HERMA systems make them particularly well suited to cover the wide spectrum of products and applications in the chemical industry. Moreover, HERMA systems are highly stable and capable of handling large loads without impairing the high throughput. High-performance printing, camera and control systems provide maximum reliability, up to and including controlled rejection of products or labels. Precise, hygienic and fast – for perfectly aligned labels. When labeling paint buckets, cans or similar containers made from metal or plastic, our systems also take the presence of the handles into account. The handles must be raised at exactly the right time during the labeling process in order for the labels to be applied correctly. The systems can also take weld seams into account. A sensor is used to detect the seam. The bottles are then aligned in a roller prism and labeled. The roller prism eliminates spiral misalignment, leading to perfectly applied labels.
