For food and consumer goods brands in the UK, eco-friendly packaging has shifted from a “nice to have” to a competitive and regulatory necessity. The pressure is coming from every direction: customers who want visible proof of sustainability credentials, retailers enforcing stricter supplier requirements, and government legislation — particularly the UK Plastic Packaging Tax — creating real financial consequences for getting it wrong.
The challenge for most packaging buyers is sorting through the noise. “Sustainable” and “eco-friendly” are terms applied freely, often to products that don’t hold up under scrutiny. This guide cuts through the confusion. It explains what genuinely sustainable flexible packaging looks like, how the two main routes — recyclable mono-material and compostable — compare in practice, and what the implications are for UK brands buying packaging today.
At Aropack, we supply both. This guide will help you make the right choice for your product, your brand, and your customers.
Why Eco Packaging Matters More Than Ever for UK Brands
The regulatory context
The UK is mid-transition through the most significant overhaul of packaging legislation in a generation. Two policies above all others are reshaping buying decisions.
Extended Producer Responsibility (EPR) shifts the cost of collecting and recycling consumer packaging onto the businesses that put it on the market. From 2025, UK producers and importers are required to report on the packaging they place on the market and pay modulated fees based on recyclability. Packaging that is easier to recycle attracts lower fees; packaging destined for landfill or incineration costs significantly more. For many brands, this alone is compelling a hard look at current packaging specifications — and a move towards formats that perform better under EPR.
UK Plastic Packaging Tax (PPT) is already in force. It applies to any plastic packaging manufactured in or imported into the UK that contains less than 30% recycled content by weight. For buyers of flexible plastic packaging — pouches, films, bags, sachets — this is a direct cost sitting on your P&L if your current packaging doesn’t meet the recycled content threshold. We cover the detail and the numbers in the PPT section below.
Consumer and retailer expectations
Consumer demand for environmentally friendly packaging has been building for years, and it has now reached the point where it influences purchase decisions at shelf. UK consumers increasingly prefer brands that demonstrate credible, verifiable sustainability credentials — and they are better placed than ever to spot hollow claims.
Major UK retailers have their own packaging commitments. WRAP’s UK Plastics Pact targets include making 100% of plastic packaging reusable, recyclable, or compostable, and achieving 30% average recycled content across plastic packaging. Brands supplying these retailers are expected to align.
For UK brands in food, supplements, pet food, coffee, and snacks, the question is no longer whether to move to eco packaging, but which option to choose and how to do it without compromising performance.
Aropack Mono: Recyclable Flexible Packaging Built for UK Brands
The most significant development in sustainable flexible packaging in recent years is the arrival of high-performance mono-material films. Aropack Mono is our recyclable flexible packaging rang, built on mono-polyethylene (BOPE / mono-PE) and mono-polypropylene structures, engineered to deliver everything brands need from flexible packaging without the recyclability barrier of traditional multi-layer laminates.
Why conventional laminates are the problem
Standard flexible packaging is built from multiple layers of different polymers, typically PET, nylon, and PE, bonded with adhesive. This structure provides excellent barrier performance, but it makes the packaging almost impossible to recycle through standard UK infrastructure. Most mixed-laminate pouches and films are classified “Don’t Recycle” under the OPRL labelling scheme and go to landfill or energy recovery.
Aropack Mono solves this by using a single polymer family throughout the structure. The result is packaging that:
- Carries the LDPE 4 recycle code, compatible with UK soft plastics recycling infrastructure
- Is OPRL “Please Recycle” compliant — carrying the label UK consumers recognise and trust
- Reduces CO₂ emissions by approximately 33% versus standard multi-layer laminates — rising to 55% when 30% post-consumer recycled (PCR) content is incorporated
- Qualifies for UK Plastic Packaging Tax exemption when manufactured with 30% PCR content
- Supports full print quality, barrier options, zipper closures, windows, and stand-up formats
Aropack Mono is available across our full range of recyclable pouches and recyclable films. View the full technical specifications and available formats on our sustainable packaging page.
Understanding OPRL: What Those Recycle Labels Really Mean
If you’re specifying eco packaging for the UK market, you need to understand OPRL, the On-Pack Recycling Label scheme. Run by the not-for-profit OPRL Ltd, it provides the standardised recycling labels that appear on the majority of UK consumer packaging. Getting this right matters commercially: OPRL status directly affects EPR modulated fees, retailer compliance, and how your brand’s sustainability claims are perceived.
The three labels
Please Recycle (green label): The packaging is widely collected for recycling across the UK. For flexible plastics, this typically means mono-PE or mono-PP structures that can enter the LDPE 4 soft plastics stream — either via supermarket drop-off or, increasingly, kerbside collection.
Recycle with bags at large supermarkets (yellow label): Collected at major supermarket soft plastics drop-off points. As the UK’s soft plastics infrastructure develops, more of this packaging is moving into kerbside collections.
Don’t Recycle (black/grey label): The packaging cannot currently be recycled via UK collection systems. Most traditional multi-layer flexible laminates carry this designation.
Why OPRL status matters for B2B buyers
- It directly determines how your packaging is assessed under EPR modulated fees, “Please Recycle” packaging will attract lower fees than “Don’t Recycle”
- It provides a credible, independently verified sustainability claim for your product
- Major UK retailers increasingly require OPRL compliance as part of new listing and range review criteria
- It gives your customers clear, trusted end-of-life instructions, reducing contamination in recycling streams and improving real-world recyclability
Aropack Mono carries the OPRL “Please Recycle” designation. This is a verified, substantiated claim, not a vague “eco-friendly” badge.
Mono-PE vs Compostable: Which Eco Packaging Option is Right for Your Brand?
Recyclable mono-material packaging and compostable packaging are the two main routes to genuinely sustainable flexible packaging. They are frequently confused with each other, but they serve different needs and work via completely different end-of-life mechanisms. Here is a clear comparison.
Recyclable Mono-Material (Aropack Mono)
Aropack Mono pouches and films are built on mono-PE (BOPE) or mono-PP. They perform like conventional flexible packaging, printable, available with gloss or matte finish, with barrier options for oxygen, moisture, and aroma but are designed for recycling within the UK’s existing infrastructure.
Best suited to:
- Food products requiring gas flushing, oxygen barriers, or extended shelf life
- Brands supplying mainstream UK retailers with OPRL compliance requirements
- Companies seeking UK Plastic Packaging Tax relief via 30% PCR content incorporation
- Products requiring zipper closures, hang holes, windows, or stand-up formats
- Medium to high print run volumes using flexographic or rotogravure printing
Key limitations:
- Requires consumer access to soft plastics recycling (supermarket drop-off or kerbside)
- Not suitable for hot-fill applications above mono-material heat resistance thresholds
Compostable Packaging
Our compostable packaging range is manufactured from renewable materials such as cellulose/PLA or kraft/PLA multilayer structures. All products are certified to EN 13432 — the international standard for compostable packaging and carry TÜV Compostable certification. Available in pouch and roll stock formats with compostable zippers and non-toxic inks.
Best suited to:
- Brands in organic, health food, or premium natural product categories where composting aligns with the brand narrative
- Dry goods: coffee (cold fill), loose-leaf tea, snacks, herbs and spices
- Direct-to-consumer, farmers’ market, and independent retail brands where end-of-life communication is possible
Key limitations:
- Not suitable for hot-fill or high-temperature product applications
- Typically requires industrial composting facilities for full certified breakdown, home composting performance varies by material
- Does not carry the OPRL “Please Recycle” designation
- Generally carries a cost premium over conventional and mono-material formats

UK Plastic Packaging Tax: What Flexible Packaging Buyers Need to Know {#ppt}
The UK Plastic Packaging Tax (PPT) is one of the most direct financial incentives to move towards eco packaging. Introduced in April 2022 and currently rated at £217.85 per tonne (2024–25), it applies to any plastic packaging component manufactured in or imported into the UK that does not contain at least 30% recycled content by weight.
For buyers of flexible plastic packaging pouches, films, bags, sachets, this means you if:
- You import finished packaging from overseas (you, not your overseas supplier, are the liable party)
- You manufacture plastic packaging in the UK
- Your annual throughput across all plastic packaging components exceeds 10 tonnes
The Aropack Mono PPT advantage
Aropack Mono manufactured with 30% post-consumer recycled (PCR) content qualifies for PPT exemption. For businesses placing significant volumes of flexible packaging on the UK market, this is a meaningful cost saving.
As an illustration: a business placing 20 tonnes of flexible plastic packaging per year, currently with no recycled content faces a PPT liability of approximately £4,357 per year. Switching to Aropack Mono with 30% PCR content removes that liability entirely, with no change to format, print specification, or supplier.
Aropack provides the material composition documentation required to support your PPT exemption claim, including certificates confirming the recycled content percentage by weight.
