1. What is laminating?

Laminating is the process through which two or more flexible packaging webs are joined together using a bonding agent. The substrates making up the webs may consist of films, papers, or aluminum foils. The multi-layer composite structure can be produced either through a process using adhesives or by extrusion. The choice of the most suitable web-laminating process is mainly dictated by the end-use of the product. A number of different technologies are available that cover a wide variety of applications in the food and non-food packaging industries.

Web lamination is used to improve the barrier properties of the packaging material in order to protect the packaged item and increase its shelf life. Typically flexible packaging laminates have three main functions: mechanical properties that improve the strength of the material by making it more resistant to tearing, punching, etc. that protect it, especially during packaging, distribution, and storage; the barrier properties that protect from outside deteriorating agents (i.e. light, moisture, gas, oxygen, pathogens and spoiling agents) and also prevent loss of the product qualities such as freshness and aroma in the case of food; and finally, the substrate sealability that hermetically closes the flexible packaging.

2. Where does laminating fit in the flexible packaging film process?

Lamination usually takes place after the substrate printing, and before reel slitting and subsequent processing on form-fill-seal machines. In less common instances where the web is printed externally, lamination is carried out before the substrate printing.

3. In what applications would be laminating be ideal?

Basically, all applications where the product needs to be protected and its shelf life extended. This applies to a huge variety of food products for human and animal consumption, but applications are almost as common for non-food products, which can require functional and highly technical film structures.  In the food sections, these range from the packaging of ready-to-eat products such as snacks, ice creams, biscuits, drinks, or products such as coffee and frozen food, to applications such as boil-in-bag pouches or freezer-to-microwave products. In the non-food section, laminated materials may be used for insulation, solar panel back sheets, and packaging of liquids for the cosmetic industries.

4. Are you seeing any new developments or techniques in laminating? If so, what are you noticing?

The trend in the packaging industry is to use less material and generate less waste to dispose of while extending the product’s shelf life. Hence new developments are particularly strong on the part of the film and other consumable products.
