A number of substrates can adhere together and may consist of film, paper, or metal foil in varying configurations. The multi-layer composite structure can be produced either through a process using adhesives or by extrusion. The most acceptable multi-layer laminating process is determined usually by taking into consideration what the product is, that is being packaged. Numerous different packaging techniques are available that encompass the wide variety of applications in food and non-foodstuffs packaging production. • Benefits of laminated packaging materials • • Resealable and versatile consumer-friendly pouches. • • Added protection and performance • • Dependable and long-lasting bagging • • Reduction of the overall carbon footprint and transportation cost for a sustainable solution. • Multi-laminated films are used to provide superior barrier attributes of the packaging material in order to protect the packaged item and dramatically increase their 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. • Lamination usually takes place after printing, and before reel slitting and subsequent processing on form-fill-seal machines. In less common instances where the laminated film is printed externally, lamination is carried out before printing. • Applications where the packaged product needs to be protected and its shelf life extended is the perfect recipe for laminated packaging use. This is most relevant in the never-ending variety of food products for human and animal consumption. Applications are almost as common for non-food products, which can mandate functional and extremely technical film structures. In the food sectors, these range for 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 backsheets and packaging of liquids for the cosmetic industries. • Trending in the flexible packaging industry is to use less material thereby generating less waste. Laminated packaging drastically increases the packaged product shelf life. • As a laminated film manufacturer, International Plastics has been in the flexible packaging business since 1964.
