Flexible Packaging
For almost 40 years, Henkel has been manufacturing special adhesives for laminating various materials, such as those necessary for flexible packaging.
Food packaging has to fulfill several tasks: information, segmentation, protection and preservation. These requirements led to the development of packaging that is flexible and light, yet tear- and compression-resistant, and guarantees that freshness and quality are protected until the product is used. Snacks, like chips or crackers, have to be kept dry. Meat and cheese need to stay fresh and hygienic. The flavor should never escape from coffee or tobacco packages, nor should acid corrode the inner layer of juice packaging.
Light and flexible packaging would not be possible without laminates. They combine the desired properties of various materials, such as paper and plastic films or aluminum foil. Each substrate brings in its own advantages. Depending on the intended use of the package, there may be two, three or four layers. In the laminator, the films are bonded with the help of special adhesives to form a new composite material – at machine speeds of 600 meters per minute or more.
