In any case, polymers are not always modern synthetic products. In fact, we have been using naturally occurring biopolymers (such as asphalt or resins) for thousands of years. However, when we talk about 'plastics', we usually mean synthetic polymers that are widely used in practical everyday life, such as PVC, polypropylene, polyethylene or polyester.
The requirements of the printing and packaging industry have changed. New coloring methods, new surfaces and processing options have made plastics an increasingly popular medium for designers, which in turn has received corresponding attention from the printing industry. Experts estimate that the use of synthetic materials rose by 10-15% between 2005 and 2006. In places where paper and cardboard were once the main information carriers, further industrial development has produced a significant shift in interest. More specific requirements have emerged for the packaging, protection, transport and display of goods. As a result, the requirements to be met by the printing substrate become more complex:
* The label is required to be tear-resistant and waterproof, but it must be easy to print or write on it.
* Documents should be more durable and cannot be torn even when used under extremely harsh conditions.
