Protecting product integrity and delivering the product as intended to the customer's hands has always been the goal of the packaging industry. Efforts to change designs, material composition, or packaging engineering have been made to increase packaging integrity. Thus, every kind of packaging must be sturdy and can withstand rough handling during transportation.
Paper and cardboard are two of the easiest materials to get damaged, stained, or ripped. They are often laminated with other materials to increase durability and protect printed materials from fading. Follow this article’s short explanation of the wonders of paper lamination and their roles in strengthening paper packaging everywhere.
What is Paper Lamination
Laminating paper-based materials has been a known practice for dozens of years. In the 1900s, people would encase films, photos, and important papers between two sheets of glass to protect them from dust and possible extensive damage.
As technological advances evolve, flexible materials are used to laminate paper-based products such as Argha’s polyethylene film, Areta. These thin, transparent materials are attached to the base paper materials using adhesives and are pressed with high heat and pressure. Laminated paper meant for product packaging offers superior strength, stability, and moisture resistance that can protect the product from external damage while keeping it pristine on the inside.
How is Paper Lamination Used in Flexible Packaging
Paper lamination can be found in several industries, including food packaging, industrial packaging, and many other consumer products. Aseptic packaging, for instance, makes great use of paper lamination for the top external layer and two innermost layers of the packaging. For F&B products, paper lamination is among the few that can safely be in direct contact with the products without risking possible contamination. As containers are shaped, pre-sterilized food products are poured into them before they are hermetically sealed in a sterile environment. As flexible packaging can be easily shaped and printed on, paper lamination can improve its barrier properties and extend the shelf life of food products.
Paper lamination can also be found in non-food applications, which can require functional but highly technical film structures. Solar panel back sheets, magazine and book covers, insulation, and packaging of cosmetic liquids utilize the non-stick properties of lamination to keep products fresh and safe until they reach the customer’s hands.
