Tamtam tracks 48 Plastics Manufacturing companies headquartered in the United Kingdom. This list ranks all of them by number of employees on LinkedIn, led by KlΓΆckner Pentaplast, Polypipe and Victrex. Their median headcount is 58. Half of them were founded in 1983 or later. The most common headquarters are Doncaster (2), Huddersfield (2) and Northampton (2).
This selection of plastics manufacturing companies in the United Kingdom includes a range of established firms, many of which have a significant global presence. Companies like KlΓΆckner Pentaplast and RPC Group Limited specialize in polymer conversion for packaging and non-packaging markets. Others, such as Victrex, are global leaders in advanced polymer solutions, while Kingspan Water & Energy focuses on sustainable water and energy solutions.

## How this list is built
Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 13, 2026.
