With mandatory kerbside collections of flexible plastic packaging due to be introduced across England by March 2027, local authorities are entering a crucial planning phase. Containment will play a central role in the success of these services, both in terms of operational practicality and material quality.
The recently published FlexCollect Final Report provides a strong evidence base, highlighting what has worked well during the UK’s largest trial of flexible plastic collections. At Cromwell Polythene, we are ready to help all local authorities apply these insights to real-world service design, with reliable products that support policy compliance and recycling performance.
Plan Early, Procure with Confidence
Many Material Recovery Facilities should be able to accommodate bagged flexible plastic with little or no modification, making this an efficient and scalable collection model.
However, sourcing high volumes of compliant sacks at short notice may become challenging as the 2027 deadline approaches.
Procuring in 2026 allows time to:
- Conduct local trials
- Educate residents and crews
- Integrate bags with new or existing recycling streams
- Avoid market pressure and delays
Using a UK-based merchant like Cromwell Polythene offers further advantages like trusted quality bags made to specification, secure lead times, and excellent service from quote to delivery.
From Policy to Performance
Bags are not just containers. They are communication tools, contamination barriers and logistical enablers that sit at the frontline of any successful recycling system. When selected and deployed well, they simplify participation for households, support crews on the ground, and improve material quality for processors.
Critically, bags can also play a powerful educational role. By printing clear visual instructions directly onto the sack, such as what materials are accepted, how to present the bag, and whether to tie or knot, local authorities can deliver consistent guidance at the point of use. This ensures residents are reminded of best practice every time they engage with the service.
Printed messaging can reinforce behaviour change and reduce contamination risks without reliance on external leaflets, signage or digital communications. In areas where language diversity or literacy may be a barrier, using colour-coding and iconography on the bag can further enhance clarity.
When bags are lightly tinted, they not only help sorting staff visually identify contents but also create a sense of accountability. Residents are more likely to follow guidance when the contents of their recycling are visible.
The right sack therefore becomes an integrated part of the service design, combining strength, recyclability and clarity with educational value. Cromwell Polythene works closely with local authorities to incorporate schemes that support each council’s goals.
Planning Ahead
As we begin a new year and approach the 2027 milestone for flexible plastic collections, now can be the ideal time to start planning. Selecting the right containment is not just about compliance. It is about designing a system that works, and that starts with the bag.
