Parkside flexible packaging and the shift to recyclable pack design
Why Parkside matters in flexible packaging discussions
Parkside flexible packaging is a useful case study for brands tracking the move from broad sustainability language to specific, testable pack design. The company’s public product information and recent case studies point to three main routes: recyclable paper-based structures, accredited compostable materials and recyclable plastic formats, including monomaterial and PET-based lidding films.
The wider lesson is not that one material can solve every application. Barrier performance, sealing, line speed, consumer disposal behaviour and local recycling or composting infrastructure now have to be considered together. That is becoming more important as the EU Packaging and Packaging Waste Regulation began applying on 12 August 2026, and England is scheduled to add plastic film and bags to household plastic recycling collections from 31 March 2027.
For packaging buyers, Parkside’s recent projects reflect a practical shift: sustainability claims are becoming more application-specific. A cookie wrapper, a root vegetable flow wrap, a crisp packet and a lidding film may all sit within flexible packaging, but each has a different technical role and a different end-of-life route.
What Parkside flexible packaging covers
Parkside describes its flexible packaging offer across pouches, flow wraps, lidding films, film laminates and bags. Its public materials also highlight UK and Malaysia operations, which is relevant for brands comparing regional supply, technical support and market access. The portfolio uses sustainability-led language, but it is not built around one material family.
A clearer way to assess the offer is by end-of-life route. Recyclable paper formats are intended for paper collection streams where the full structure remains compatible with recycling requirements. Compostable Park2Nature materials target home or industrial composting routes, depending on the specification and certification. Recyclable plastics and lidding films target plastic recycling systems, often by reducing material complexity or matching the film to a compatible tray.
| Route | Typical Parkside examples | Best-fit packaging question |
|---|---|---|
| Recyclable paper | Recoflex paper, flow wrap paper, high-barrier paper, metallised paper | Can the pack reduce plastic while still sealing, protecting and recycling in a paper stream? |
| Compostable flexible packaging | Park2Nature films and laminates | Is composting a credible end-of-life route for this product and market? |
| Recyclable plastic formats | Monomaterial laminates and PET lidding concepts such as Popflex | Can the pack remain functional while improving compatibility with plastic recycling? |
This is why the Parkside example is useful for the wider market. Flexible packaging is often discussed as one category, but the design decisions are highly specific. Moisture barrier, oxygen barrier, grease resistance, aroma protection, cold-chain durability, shelf presentation and filling-line efficiency all influence whether a structure is viable.
Recyclable paper is moving from idea to engineered format
Paperisation has become a major theme in flexible packaging, but Parkside’s examples show why the term can be too simple. A successful paper-based flexible pack still needs the right coatings, sealability and machine performance. Parkside positions its Recoflex range around paper materials that can deliver barrier performance, heat sealing and printability while remaining designed for recycling.
The Cox & Co chocolate wrapper, recognised in 2024 in The Grocer New Product & Packaging Awards, illustrates this direction. Parkside’s published case information says the paper-based flow wrap was developed over an 18-month period and used water-based barrier coatings to help protect against moisture and oxygen. The value of the case is not only the award result. It also shows that recyclable paper packaging may require extended technical development when premium appearance, product protection and existing hot-seal equipment all have to work together.
A newer example, published by Parkside on 29 October 2026, involves Sofi’s Cookies. In that case, the brand moved from a compostable wrapper toward a recyclable paper-based pack for individually wrapped cookies supplied to hospitality customers in Greece and Spain. Parkside’s account is useful because it also states a limitation: the heat-seal coating needed for pack performance contained some petrochemical-derived material. As a result, the development brief moved away from a simple plastic-free claim and toward real-world recyclability. That distinction is increasingly important in packaging communication.
What this means for food brands
Food brands considering paper-based flexible packaging should not treat paper as a shortcut. Paper can support a natural look and lower-plastic positioning, but fatty, moist, frozen or aroma-sensitive products often require functional coatings. The commercial question is whether those coatings preserve recyclability in the intended market while protecting the product through packing, distribution, retail and consumer use.
Case studies show the value of performance data
The strongest information in Parkside’s public case studies is not generic sustainability wording. It is measurable or verifiable detail. Riverford’s root vegetable project is a good example. Parkside says the move from premade paper packs to an automated vertical form-fill-seal paper design improved packing speed from 25 packs per minute to 35 packs per minute. The same case also describes a move from 100gsm material to 90gsm material, while maintaining a kerbside-recyclable paper format and avoiding the need for secondary packaging.
That kind of detail matters because sustainable packaging changes can fail when they add operational cost, slow a line or increase product damage. A pack that is theoretically recyclable but weak in distribution may create more waste elsewhere. The Riverford example suggests that recyclable flexible packaging should be assessed across the full system, not only at the disposal stage.
Parkside’s compostable work with Two Farmers shows a different type of system thinking. The Two Farmers case, published in 2026, focuses on crisp packaging, a demanding application because the pack has to preserve crunch, seal reliably and maintain shelf appeal. Parkside says its Park2Nature material uses renewable feedstocks and is independently accredited to home composting standards for the relevant structure. The case also describes Two Farmers’ broader waste-management approach, including fragmenting compostable packet material for use with production waste in an on-site anaerobic digestion system. That is not a universal model, but it shows why compostable packaging works best when the disposal route is actively planned rather than assumed. See also: BOX DESIGN.
Regulation is making vague claims harder to defend
The regulatory direction in Europe and the UK is one reason Parkside flexible packaging examples are worth watching. The EU Packaging and Packaging Waste Regulation was adopted in December 2024 and began applying on 12 August 2026. Its broad direction is to reduce packaging waste, harmonise rules and make all packaging placed on the EU market recyclable in an economically viable way by 2030. It also keeps recycling targets for major materials, including higher 2030 targets for paper and cardboard and for plastics.
In England, Defra guidance on Simpler Recycling says plastic film packaging and plastic bags will need to be collected with plastic recycling from households from 31 March 2027. The same guidance distinguishes compostable or biodegradable plastic packaging from conventional plastic recycling streams. That distinction matters: a compostable pack is not automatically suitable for plastic recycling, and a recyclable film is not automatically compostable.
The UK Plastic Packaging Tax is another pressure point for plastic formats. It applies to plastic packaging manufactured in or imported into the UK that does not contain at least 30% recycled plastic, subject to the details of the tax rules and exemptions. This helps explain why recycled-content claims, monomaterial designs and PET-based lidding films are now discussed alongside paperisation.
How to evaluate a Parkside-style packaging switch
The main lesson from Parkside’s public examples is that material choice should start with the product and the intended end-of-life route, not with a slogan. A bakery item with grease risk, a fresh produce pack exposed to moisture and a premium crisp packet with aroma and crunch requirements need different structures. The best material is the one that protects the product, runs on the available machinery and gives consumers a credible disposal route in the target market.
- Define the product risk first. List moisture, oxygen, grease, aroma, puncture, light and temperature requirements before choosing paper, plastic or compostable structures.
- Check the actual collection route. Recyclable, kerbside recyclable, store-drop-off recyclable, home compostable and industrial compostable are not interchangeable terms.
- Test on the packing line. Seal integrity, speed, machinability and reject rates can decide whether a sustainable pack is commercially realistic.
- Be precise with claims. If a heat-seal coating or barrier layer remains necessary, the claim should describe recyclability or reduced plastic accurately rather than overreaching.
- Compare total system impact. A lighter pack, faster filling process or removal of secondary packaging may be as important as the headline material change.

Frequently asked questions
Is Parkside flexible packaging only paper-based?
No. Parkside’s public product information includes paper-based formats, compostable flexible packaging and recyclable plastic formats such as monomaterial laminates and PET lidding concepts. Paper is a major focus, but it is one route within a broader flexible packaging portfolio.
Does recyclable paper packaging always mean plastic-free?
No. Some recyclable paper packs may still use coatings or seal layers to deliver grease resistance, oxygen barrier or heat sealing. The more important question is whether the complete structure has been designed and tested for the intended recycling stream.
When does compostable flexible packaging make sense?
Compostable packaging makes the most sense when the product, consumer instructions and local disposal route support composting. It can be useful for specific applications, but it should not be treated as a replacement for recycling where composting infrastructure is not available or accepted.
Why are monomaterial packs important?
Monomaterial packs are designed to reduce the material complexity that can make flexible packaging difficult to recycle. They are especially relevant where brands need plastic performance but want better compatibility with plastic recycling systems.
What is the main takeaway for brands?
The main takeaway is to match the packaging structure to the product, machinery and verified end-of-life route. Parkside’s examples show that sustainable flexible packaging is increasingly about evidence, testing and accurate claims rather than broad material preferences.
