Our Environmental Ethos

Hanmere Polythene is an environmentally aware company. We are consistently working to assess and improve the environmental impact of the work that we do, and supporting our customers as they make greener choices. Every product that is made by Hanmere is 100% recyclable, and the business is supporting the development of chemically recycled polymer from post-consumer waste. Ultimately this method of recycling is intended to result in recycled polymers approved for use in food contact materials such as tray liners and plastic bags for ingredients. For our clients, we offer environmental process auditing to help customers limit their plastic use and manage their waste streams. This helps us to provide solutions that use the minimum amount of plastic, and to ensure that it can be recycled responsibly following its use.

Our History

From our early days as a family-run company in Letchworth, Hertfordshire, we have invested in and expanded our business to make Hanmere the business it is today.

Incorporated on April 6th 1966, Hanmere Polythene was one of the first innovative  polythene  and plastic bag manufacturers in the UK. We quickly began to make a name for our business as an organisation that valued high standards and advanced film technologies. Within 10 years the business had developed both HDPE and LLDPE Films, the latter in conjunction with Dow Chemicals, and was well on its way to revolutionising the processing and printing techniques.

As time went on, Hanmere was able to develop our own proprietary plastics such as StikSak and GS69 in the 1980s, and Hankraft and Hanbar in the 1990s. Alongside this was recognition from leading certification bodies such as the Royal Society for Public Health (RSPH) in 1999 which was replaced by the British Retail Consortium standard in 2002 and has now evolved into the Brand Reputation Compliance Global Standard (BRCGS) of today. This has been held for more than 20 years under its various forms. This has been consistently held by Hanmere for more than 20 years now. Though our machinery and processes have improved, our high quality standards have remained the same. In 2017, we were able to develop a ground-breaking 30 micron film that was still able to meet the stringent requirements of the M&S Guidelines.

In 2020, Hanmere began the next phase of its growth by acquiring Plasmech. This began our steps into a larger, Pan-European plastics group. Hanmere’s history has led us to some great advances and opportunities in the present day. We hope to continue this legacy.
