Established in 1967 providing diecut shapes of release papers for food and self adhesive tape interleaving. This die-cutting service evolved in the early 70's into gaskets and joints for the plumbing and heating equipment suppliers and manufacturers. By the late 70's the management of GML was taken on by the second generation who began evolving the paper converting part of the business to include products for Industrial and Retail Packaging.

A two colour flexo press and wax coating machine were acquired in 1981 and Printed Waxed Breadwrap was added to GML's range of products. Being printers and coaters of papers, the product range was able to expand. Coupled with investment in high speed sheeting and slitting equipment, a programmable guillotine and two 4 colour flexo presses the 80's was a period of expanding GML's relationship with independent packaging merchants alongside its investment in the skills base of the workforce.

Always taking an opportunity to innovate production techniques to fit a new market place, a range of protective meat wrappers was introduced in the early 90's with GML expanding its end user customer base into France and Germany, winning in 1996 an Export Achievement Award.

Riding many a storm over the next decade, a significant way-post in the life of GML was in 2012 when the first of the 3rd generation of the family joined the business making growth of its exciting Deliwraps customer base possible.

2015 started with the expectation of a further growth in output but this was halted in May of that year with a fire which destroyed the production unit and most of its converting machinery. A combination of vision and self-belief turned this near disaster into re-establishing production over the ensuing 4 months in locally rented premises whilst planning the build of a new, more purpose designed factory.

In 2018 all production was re-located into the new factory, boasting ground source heating, an array of solar pv panels, rain water harvesting and an integral warehouse.

The Management strength was further enhanced in 2020 with the joining of a second of the 3rd generation of the family.

The arrival of 2021 was marked by certification to the coveted ISO 9001:2015 Standard, testament to the Management and Employees steadfast belief in the GML of today and the GML of tomorrow. To finish off a difficult year GML was also awarded with the BRC Packaging & Packaging Materials standard.
