This also produces a high gloss finish on card and provides good
protection against damage as it is normally water proof. |

Laminated card is used for items such as menus in a restaurant. A menu will be constantly handled by customers and staff and it is important that it is protected. |
|
THE COMMERCIAL LAMINATION PROCESS | |
Commercial lamination takes two forms: Cold Lamination and Hot Lamination. Both processes are similar, as they utilise rollers pressing a layer of polyethylene, against a printed surface. These processes are ideal for printed posters, that need an additional layer of protection. |
|
THE HOT LAMINATION PROCESS | |
This process fuses a heat sensitive polyethylene film, to the surface of card. The two layers are fed into a roller press, with the laminate film as the top layer. The top ‘heated roller’, is lowered on to the card/laminate layers, as they are automatically fed into the roller press. As the card/laminate feeds through the rollers, the heat form the top roller fuses them together. |
|
THE COLD LAMINATION PROCESS | |
This process joins a card layer with a layer of clear polyethylene, which as an adhesive side. As the card/laminate layers are fed through the ‘cold’ rollers, they are joined permanently, due to the clear adhesive on the polyethylene. |
|
All these posters have being processed through the ‘commercial laminating process’. This means that they are protected against spillages, scratches and light knocks, extending their life cycle. | |
QUESTIONS: 1. Draw a simple diagram of a laminating machine and explain how it works. 2. When is it a good idea to laminate card - give three examples. |
