IN Brief:
- PPWR includes beverage reuse targets of 10% by 2030 and 40% by 2040 for relevant drinks within reuse systems.
- Amcor is placing closure performance at the centre of reusable PET and glass bottle design.
- Deposit return and reuse systems increase pressure on sealing, durability, washing resistance, and pack validation.
Amcor is advising beverage producers to reassess closure choices as the EU Packaging and Packaging Waste Regulation and expanding deposit return systems push more drinks packaging towards reuse and return models.
The PPWR framework includes beverage reuse targets requiring 10% of alcoholic and non-alcoholic beverages to be made available in reusable packaging within a system for reuse by 1 January 2030, rising to 40% by 2040. Deposit return schemes are also being introduced or expanded across multiple markets to increase container return rates and improve the quality of recovered material streams.
Closure performance becomes more demanding when bottles move from single use into reuse. Reusable PET and glass bottles are exposed to repeated handling, washing chemicals, temperature changes, refilling, transport, return logistics, inspection, and consumer use. The closure still has to deliver sealing performance, tamper evidence where required, opening convenience, carbonation control, and compatibility with the bottle neck finish.
Uli Kobert, Product Line Director at Amcor, said: “PPWR is accelerating the shift towards reuse systems, and that has real implications for packaging choices. Amcor supports customers with closure solutions for reusable PET and glass bottles, alongside technical expertise, to help them prepare for deposit return schemes and the operational realities of reuse, delivering responsible packaging solutions without compromising on performance.”
Deposit return systems place packaging into a more circular physical flow. Empty containers return through collection points, reverse vending systems, retail networks, logistics hubs, or dedicated pooling routes. Those containers then need sorting, inspection, washing, refilling, and redistribution. Germany is frequently cited as one of the strongest performing deposit systems, with return rates for eligible single-use drink containers widely referenced at around 98%.
Reuse changes the definition of pack performance. A single-use bottle and closure must protect the product until consumption and disposal. A reusable bottle system must protect the product, survive the return system, withstand washing, remain inspectable, and re-enter filling without introducing unacceptable risk. Closures sit at the functional centre of that system because seal failure can affect safety, carbonation, shelf life, leakage, and consumer confidence.
The same operational logic is shaping wider circular packaging discussions, with reuse advocates pressing for transport packaging to be built more firmly into EU strategy. Reuse depends on assets moving through a controlled loop. The environmental case weakens if return rates are poor, washing is inefficient, breakage is high, or packaging fails before reaching its intended number of cycles.
Beverage producers will need to validate closures as part of the full system rather than as a single component. Tests must consider torque retention, cap removal force, carbonation retention, stress cracking, liner performance, tamper band behaviour, thread wear, caustic resistance, thermal exposure, and compatibility with washing and filling equipment. A closure that works on a new bottle may behave differently after repeated cycles.
Reusable glass and PET also create different technical conditions. Glass is durable and familiar in many return systems, but it brings transport weight and breakage considerations. Reusable PET is lighter, but it requires careful management of scuffing, bottle ageing, washing conditions, odour, and mechanical wear. The closure must match the chosen container route.
The shift also affects operations beyond the filler. Return logistics, crate design, bottle inspection, rejected container handling, washing capacity, data capture, and retailer participation all influence whether reuse can scale. Packaging procurement is becoming more closely connected to logistics, engineering, quality assurance, and sustainability teams.
Regulatory timelines are adding urgency to validation work. Beverage producers planning for 2030 need time for market trials, infrastructure partnerships, consumer participation, bottle pool design, cleaning validation, and pack performance evidence. The closure may look like a small component, but in a reuse system it helps decide whether the loop remains reliable.
Amcor’s guidance reflects a wider change in packaging decision-making. Recyclability, recycled content, reuse, deposit return, and producer responsibility are now being designed into packs at the same time as shelf life, speed, cost, and brand presentation. Beverage closures are becoming one of the key engineering points where regulation, circularity, and factory performance meet.
