Plastic Film Recycling - The Solution

Plastic film is typically manufactured from either polyethylene or polypropylene and if recycled correctly can achieve a high profit margin as a recycled polymer. Traditionally, plastic films have created huge problems in recycling lines. Films can get wrapped around machinery, reducing its efficiency and potential machine downtime. This has led to the majority of plastic film being rejected from plastic recycling facilities and being sent either to energy from waste centres or unfortunately straight to landfill.

With many local authorities as well as many major supermarkets now providing dedicated plastic film collections, many pure film waste streams now exist; creating an opportunity for a uniformed in-feed material. This has created a huge opportunity for the industry to tap into a previously difficult source of recyclable polymer.

To account for this shift in the market, Rotajet have developed a series of standard plastic film recycling lines that can handle capacities ranging between 500Kg to 3MT per hour. The typical process flow is outlined below.

The Complexity of Film Recycling


With plastic film typically being made from polyethylene or polypropylene, it can be a highly profitable material if recycled correctly. And with plastic film collections now in place across the UK, opportunity is arising for businesses to take advantage of the profits offered by plastic film recycling, whilst reducing landfill at the same time.

Compared to other types of plastic recycling, recycling plastic film can come with a range of complexities that wouldn’t be present with other types of plastic. As a low bulk-density material, film is lightweight with a large surface area meaning that it can be particularly difficult to wash and dry

With large quantities of plastic film comes large quantities of air which can complicate the process further. This means that any cleaning medium must be equipped to handle large capacities of product. On top of this, the design of plastic film makes it susceptible to getting wrapped around the plastic washing machinery, causing a reduction in the efficiency of the machine as well as risking potential downtime. 

With over 30 years’ experience in the industry, Rotajet understands these complexities and can offer complete solutions to recycling plastic film. By increasing the capacity of our plastic recycling lines, we can offer standard solutions to processing up to 3MT of plastic film per hour.

Shredder In typical situations, a shredder is used for the initial size reduction of the material. The feed stock is normally reduced down to a shred of 40-50mm.

RJ-FW/22 – The shredded material is then passed through a high-performance friction washer which removes contaminants with both the impingement from the water jets and the pulverising action of the high-speed rotary paddles.

RJ-HKS50 A sink float is used to separate the plastic film from contaminants such as dust and sand. We typically recommend the sink float to be positioned prior to the granulator, to protect the granulator from adhesive materials which would cause undue wear.

RJ-GR55/w ­– Our robust wet granulators reduce the particle size into a uniformed recycled plastic suitable for resale.

RJ-MD-55This horizontal mechanical dryer is the most efficient way of dewatering granulated and shredded plastics. The machine is fitted with a Rotor which rotates at high speed (approx. 1450rpm). To ensure our dryers are simple to maintain, the rotor is fitted with easy-to-change wear paddles manufactured from D2 steel.

RJ-SC Finally, one of our screw presses is used to squeeze out the remaining moisture to allow for efficient extrusion.
