Norwich Union (NU) aims to improve the plastics industry's poor accident rate with a safety guide it developed with trade publication Plastics & Rubber Weekly (PRW).
The guide was launched this week, which is European Health & Safety at Work Week.
NU product manager Matt Frost said the UK was the world's leading supplier of plastics and production is set to increase further.
"The sector is primarily made up of small to medium-sized enterprises and also has one of the highest accident rates in the industry," he said.
"Major accidents can put smaller firms out of business and even a minor incident can cause significant losses. PRW has drawn on the expertise of the Health & Safety Executive and NU Risk Services to put together this guide, aiming to make managers aware of potential risks and draw up ways of minimising them."
