M-real Consumer Packaging’s Carta range features lightweight and sustainable boards developed especially for luxury packaging such as beautycare, high quality consumer goods and confectionery.
While sustainability is another issue of vital importance to the industry, M-real has chosen to invest in lightweight products in order to help its customers to reduce their own carbon footprint and waste, but also their costs, and without loss of printability, stiffness or other benefits.
Lightweighting of products thus became a major part of M-real’s strategy in recent years. According to M-real, lighter weight boards offer the same properties of stiffness and bulk as heavier conventional grades, but in lower substances. This means they can be specified for luxury applications without losing a quality feel. They offer cost savings and benefit the environment thanks to lighter transport weights and less waste at the end of their lifecycle.
“A key factor in lightweighting is the use of BCTMP  pulp, the development of which has been driven by M-real,” M-real claims. “M-real has also tightened its tolerances to be the tightest in the trade, ensuring better consistency in board quality. This results in clear savings and improves sustainability.”
For example, in board thickness M-real’s target value for consistency is plus or minus 3%, compared to the 5% considered the norm in the industry. “Variations in thickness lead to inconsistency in printing results, as well as stoppages and waste in converting and packing lines,” the company says.
