The company declined to comment, but PrintWeek understands that employees have been told that the site will shut down at the end of the month.

A number of workers at the business have already found jobs elsewhere, while some are actively searching for new roles.

One Slough employee described themselves as: “Looking for a new opportunity as the company has recently announced a planned closure.” 

Slough (formerly AGI Media Packaging) has historically specialised in multi-media packaging, such as CD and DVD packs.

Four-and-a-half years ago ASG shut its Swindon operation and merged that into Slough, with a remit to diversify its packaging offering into other areas, such as high-end consumer packaging for personal care products.

At the time it had sales of more than £20m.

The group also carried out some restructuring at the site at the beginning of 2016.

Slough is ASG’s only production site in the UK, although it also has a brand management and creative studio in London. Its other European operations are in Ireland, the Netherlands, France, Poland, Italy, Austria and Poland.
