Biodegradable and compostable compounds with improved heat deflection, mechanical toughness and impact strength.

High heat deflection, mechanical toughness and biodegradability.

A fully certified EN13432 high heat deflection, mechanical toughness and impact strength in combination with biodegradability or compostability are highly desirable performance parameters in a wide range of applications in the food packaging and agricultural sectors. These properties are not commonly achievable with commercially available biopolymers systems.

How it works.

The heat deflection temperature is an important measurement and provides an estimate of the service temperature for which a given polymer can withstand. Materials such as high impact polystyrene (HIPS) have a heat deflection temperature generally between 80°C and 100°C, at the higher end of this range these materials become suitable for use in hot food and beverage applications such as coffee cup lids.

In contrast the heat deflection properties of many biopolymers are significantly lower, often in the range 50°C to 60°C, therefore their service temperature is limited and thus unsuitable for use in many elevated temperature applications.

The highly improved heat deflection temperatures, excellent stiffness, tear resistance and impact resistance of the Compol™ range of materials means that the Compol™ products not only hold their shape under elevated temperatures but are not brittle allowing them to be used successfully in such environments.

In addition, the low odour properties of these materials make them ideally suited when used in direct contact with food stuffs.

All Compol™ materials have been tested and approved to EN13432 and conform to all the relevant food contact regulations including EU/D/2011 and CFR21.

Applications:  Sheet Extrusion, Injection Moulding

Wells Plastics Founded

The business was founded in 1984 by Danny Wells servicing the UK with specialist additive masterbatches for the UK film and fibre marketplace, with a particular expertise in UV masterbatches.

New Management

In 1997 Danny left the business, under new management the product range began to grow.

Bactiglas™ Launches

In 1999 the business entered antimicrobial masterbatch marketplace which would become the Bactiglas™ range of products.

Reverte™ Arrives

In 2003 Wells developed a range of oxo-biodegradable masterbatches which would become the Reverte™ range of products in 2005.


In 2006 the business began its first site expansion taking on more warehousing and office space on the same industrial estate, including an expansion of the lab facility to support the growing business.

Growing Team

In 2009 the

Technical Department expanded further

Management Buy Out

In 2011 KCP supported a management buy-out and provided investment for growth

International Growth

In 2012 Wells increased dramatically its international foot print through an expanded distribution network.

Founding Members

In 2015 Wells are the founding Member of the oxo-biodegradable plastics federation (now known as the Society of Biodegradable Polymers)

Capacity Increases

In 2018 the business underwent a significant capacity uplift with a 40% expansion and extension of the current production facility

ISO 14001

In 2019 the business achieved ISO 14001


Ecovadis Silver

In 2020 Wells achieve a Silver EcoVadis rating

A Busy Year

In 2022 Wells created the Innovation Centre, a raw material warehouse, gained a Gold Ecovadis rating and completed a Management Buy Out
