Which process is more cost-effective for high-volume production? Extrusion lamination is usually more cost-effective at very high volumes (millions of square meters per year) because the raw material (LDPE resin) is cheaper than formulated adhesives, and there are no solvent or drying energy costs. However, dry lamination offers lower startup waste and faster changeovers, making it more economical for short to medium runs. Many large converters use extrusion for base structures like paper/PE/paper and dry lamination for complex barrier structures. https://www.sinstarsl.com/dry-lamination-vs-extrusion-lamination-which-process-is-right-for-your-packaging

What are the main product quality differences I should expect? Dry lamination produces thinner, more uniform adhesive layers (typically 1–3 g/m²), resulting in a more flexible finished film with better clarity — ideal for printed pouches and transparent packages. Extrusion lamination adds a thicker plastic layer (usually 8–25 g/m²), which creates a stiffer laminate but adds bulk, puncture resistance, and a built-in sealant layer. However, extrusion lamination is prone to "neck-in" (narrower edges) and gauge variation, while dry lamination offers tighter coating control across the full web width. https://www.sinstarsl.com/dry-lamination-vs-extrusion-lamination-which-process-is-right-for-your-packaging
