An eco-friendly packaging coating to replace plastics films has been developed scientists at Sheffield Hallam University in England and Sweden’s Karlstad University, who are seeking partners to market the idea.
CaiLar, which is made from starch and clay, has been designed to encourage the use of natural based packaging. The clay-starch-plasticiser combination is said to maximise moisture and oxygen barrier properties under normal conditions.
A board substrate without any coating had a water vapour transmission rate of 340g/m2/day, which was reduced to 260g/m2/day after adding two individual layers of the starch and plasticiser.
The product, developed as part of a Sustainpack and European research programme, is initially aimed at low water content foodstuffs such as biscuits and cheese.
