The ProVantage Fluting Frigo Forte, developed by Mondi, has been designed to provide high strength packaging at a lighter weight for heavy-duty packaging applications, such as fruit and vegetable transportation, the company said.
The material would also be suitable for applications used in the cooling chain, it added.
High fibre content
The fluting offers 16% better strength properties than regular recycled fibre fluting – a property attributed to its high fibre content.
“The enhanced strength values are attributable to the higher fibre content originating from multilayer packaging,” said Mondi containerboard marketing manager Waltraud Seiner.
The fibres from this multilayer packaging are gently repulped and refined in a separate processing line at the company’s Raubling mill in Germany.
This allows for a high fibre content, but at a reduced weight – maintaining strength.
“The significantly reduced base weight of ProVantage Fluting Frigo Forte does not entail any loss of strength.”
“As shown in laboratory tests, 127 gsm ProVantage Fluting Frigo Forte can substitute 150 gsm recycled fibre fluting in corrugated board without any loss of quality. It also ensures optimum runnability on the corrugator and is easy to convert,” Seiner added.
According to Seiner, the development will allow customers to “realise appreciable cost saving potential for packaging solutions.”
“When using and converting ProVantage Fluting Frigo Forte, customers are able to realise cost savings by reducing the overall weight of a packaging solution.”
The containerboard, which is already available on the market in standard reel widths of 240-250cm, “is Mondi’s first fluting made out of 100 % recovered paper and board that meets coldest challenges with tremendous strength properties.”
“The fluting shows outstanding strength properties even when exposed to extreme climatic fluctuation,” Seiner added.
