IN Brief:
- Confectionery remains heavily dependent on flexible plastic films for barrier performance, shelf life, and high-speed wrapping.
- Paperisation, bio-based materials, and recyclable mono-materials are advancing, but each has performance and infrastructure constraints.
- Packaging regulation is pushing manufacturers to balance recyclability, EPR exposure, line efficiency, and product protection.
Confectionery manufacturers are facing a harder packaging transition than many sustainability targets imply, with flexible plastics still performing critical roles across wrapping, sealing, shelf-life protection, and distribution.
Plastic is highly visible in retail confectionery packaging, but its role starts earlier in the production system. It is used in storage, handling, conveyor contact, film wrapping, flow packs, pouches, twist wraps, multipacks, and secondary protection. The most sensitive issue remains primary packaging, where films and laminates must protect products from moisture, oxygen, contamination, odour transfer, fat bloom, stickiness, and breakage.
Chocolate, gummies, chews, hard sweets, wafers, biscuits, coated products, and seasonal confectionery all place different demands on packaging. A premium chocolate tablet may require aroma protection and fat stability. A gummy line may need moisture control and seal integrity. A wafer or filled product may require barrier performance against humidity while avoiding crushing in transit. Multipacks must combine shelf impact, portioning, machinability, and transport strength.
Substitution is therefore proving uneven. Paper-based materials can reduce plastic content and improve consumer-facing sustainability signals, but they can struggle with barrier properties unless coatings, liners, or laminated structures are added. Bio-based materials can reduce reliance on fossil feedstocks, but compostability and recyclability depend on local infrastructure and material design. Mono-material films can improve recyclability, but must still run on high-speed flow-wrapping systems and protect the product through storage and distribution.
Regulation, retailer targets, EPR fees, and corporate packaging commitments are already forcing change. The difficult question is how much performance can be preserved while the material structure is simplified. A pack that recycles more easily but shortens shelf life, increases food waste, or slows a wrapping line can move the environmental and commercial cost elsewhere.
Recyclability ratings are increasingly linked to cost exposure, with EPR assessments becoming part of packaging finance and design decisions. Confectionery manufacturers now need to understand whether a pack is likely to attract higher fees, whether it can be collected and sorted in target markets, and whether changes to material composition affect sealing, printability, and shelf-life validation.
PPWR adds a European layer to those decisions. The transition is pushing packaging teams to gather stronger evidence on recyclability, recycled content, hazardous substances, conformity, and market placement. Unresolved technical and legal questions around PPWR transition planning can move quickly into stock planning, pack approvals, and factory risk.
Confectionery plants are also exposed to SKU complexity. Seasonal ranges, retailer exclusives, multipacks, impulse formats, sharing bags, and promotional packs all create frequent changeovers. Packaging materials that need tighter process windows can increase downtime, scrap, or quality failures if they are introduced without enough line testing. Film stiffness, coefficient of friction, seal temperature, tear behaviour, static, and compatibility with coding systems can all affect output.
A stronger engineering-led approach to packaging reform is becoming unavoidable. Material trials need to be linked to line speed, seal validation, distribution testing, shelf-life studies, and recycling evidence. Packaging procurement, sustainability, engineering, quality, and commercial teams have to make decisions together because no single function owns the full risk.
The pressure is likely to intensify as retailers look for clearer packaging claims and regulators tighten producer responsibility systems. Flexible plastics will remain difficult to defend where better alternatives exist, but they will also remain difficult to remove where product protection depends on them. Confectionery is one of the categories where that tension is most visible.
The next phase of packaging change will be less about replacing plastic with one universal alternative and more about segmenting the problem. Some formats may move to paper-based wraps, some to recyclable mono-material films, some to lighter plastic structures, and some to fibre-plastic hybrids. Each route will need evidence that the pack protects the product, runs on the line, and has a credible end-of-life route. In confectionery, sustainability will be decided in those production details.
