Laminators
Lamination refers to the joining of a thin, often foil-like layer with a carrier material by means of an adhesive. The term lamina stands for layer in Latin and can also be found in laminate. A well-known example is the lamination of documents using a laminating machine.
Today, important documents or beautiful photos are often laminated to protect them from environmental influences such as dirt and moisture. The document or photo is coated with a thin layer of film which repels water, dust and, in the case of special films, UV radiation. This means that the documents are more durable, do not yellow and do not break so quickly.
Lamination can take place in various ways. On the one hand, a distinction is made between hot lamination and cold lamination. In the former case, the adhesive that bonds the film to the document reacts only under the influence of heat. This liquefies it and bonds it to the carrier material. With cold lamination, on the other hand, the adhesive already reacts at room temperature and no device is required for smaller formats. This process is particularly suitable for heat-sensitive materials that would be destroyed by hot lamination.
A further distinction can be made between pocket laminators and roll laminators. The pocket laminators work with prefabricated laminating pockets, which are available in various formats. The document to be laminated is inserted into it and the bag is pulled through the device, which closes the bag completely. With roll lamination, on the other hand, the laminating film is pulled over the document from rolls and connected to it. This system is mainly used in the professional sector, while pocket lamination is mainly used in the office and at home due to its ease of use.
