# 40 leading Plastics Manufacturing companies in England
Tamtam tracks 40 Plastics Manufacturing companies headquartered in England. This list ranks all of them by number of employees on LinkedIn, led by KlΓΆckner Pentaplast, Polypipe and Victrex. Their median headcount is 42. Half of them were founded in 1981 or later. The most common headquarters are Doncaster (2), Huddersfield (2) and Northampton (2).
These English companies specialize in plastics manufacturing, ranging from global providers of packaging and specialty films to manufacturers of cable management products and polymer solutions. The list includes established firms like KlΓΆckner Pentaplast, a global provider of rigid and flexible packaging, and Victrex, a leader in PEEK and PAEK-based polymer solutions. Other notable companies are RPC Group Limited, specializing in polymer conversion for packaging, and Zotefoams, a producer of lightweight foams for various industries.

## 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 12, 2026.
