Effective sealing of packaging during food manufacturing plays an important role in food preservation. If the seal is not robust enough, spoilage and pathogenic bacteria may be able to penetrate, potentially leading to food waste. Research at the University of Lincoln has estimated that 8% of packs leaving the factory might fail to provide sufficient protection until reaching the customer. This potentially equates to 480 000 tons of food waste. Better seals could reduce this, and lead to cost savings in the factory.This seminar will cover different ways to improve sealing of packaging, focusing on providing practical solutions to optimise existing and novel sealing methods, and possible ways to monitor the seals' effectiveness
