Since PPWR enforcement began rolling out across the EU, customs holds over packaging non-compliance have become a growing headache for brands shipping food, coffee, and pet food into the bloc. What starts as a routine packaging update often spirals into delayed shipments, rework costs, and retail onboarding delays - not because brands are cutting corners, but because small, common assumptions do not hold up to real-world enforcement.
Across supply chain audits and retail onboarding reviews, a handful of consistent gaps keep appearing in flexible packaging setups. Below are the most frequent missteps, along with practical adjustments to align packaging with on-the-ground PPWR requirements.
The "100% recyclable" print claim that falls apart at customs
Earlier this year, a premium nut brand faced nearly €12,000 in storage and rework costs after a 20-foot container of its stand-up pouches was detained in Hamburg. The packaging featured a prominent "100% recyclable" claim on the front panel, but used a standard PET/PE laminate structure - a longstanding go-to for moisture and oxygen barrier, but one that cannot be sorted and reprocessed through standard EU municipal recycling streams. Local authorities flagged the claim as unsubstantiated, and the brand had to arrange for third-party relabeling before the goods could be released.
This is far from an isolated case. Many brands take a supplier's "recyclable" product description at face value and print the claim directly onto artwork, without verifying the structural basis for the statement. Under the regulation, recyclability is not a marketing descriptor. It is tied to whether the full material structure - every layer, coating, and component - can be effectively recovered in existing waste management systems. Mixed-material laminates containing PET, nylon, or aluminum do not meet that threshold, regardless of what is printed on the surface.
Mitigating this risk starts with shifting to a true mono-material film structure, built exclusively from a single polymer family (PE or PP) with no mixed plastic layers. As a specialized flexible packaging manufacturer, LepuPouch produces recyclable packaging on a pure Mono-PE platform, with a proprietary high-barrier coating that matches the oxygen and moisture protection of traditional laminates - no tradeoff between shelf life and compliance.

Why uncertified PCR claims don't survive retail onboarding
Post consumer recycled content is one of the most accessible ways to align with PPWR's circular economy targets and one of the most frequently misapplied sustainability claims. Market audits show a growing number of brands print "30% PCR" or "made with recycled plastic" on packaging, only to hit a wall during retail onboarding when buyers request third-party verification. Major grocery chains across northern Europe now treat GRS documentation as a non-negotiable onboarding step, even in markets where formal regulatory enforcement has yet to ramp up fully.
Under PPWR, recycled content declarations require end to end traceability. This goes far beyond blending reclaimed resin into a production run: it requires GRS (Global Recycled Standard) accreditation for the feedstock, and a Transaction Certificate issued for every individual production batch to verify the recycled content percentage. Without that paper trail, claims will not pass retail audits, and in multiple EU member states, they can be classified as misleading commercial practice.
The only reliable way to stand behind PCR claims is to source from a supplier with full GRS accreditation and batch-level traceability protocols. LepuPouch formulates its PCR packaging lines using certified recycled resins, with customizable content ratios typically ranging from 30% to 50%, calibrated to balance clarity, stiffness, and mechanical performance for each product category.

How small components break your full-package recyclability
Most brands auditing their packaging for PPWR focus first on the main film structure and stop there. But a frequently overlooked detail in the regulation is that recyclability is assessed on the finished, complete package, not just the primary film. A pouch with a pure PE body but a non-PE zipper, degassing valve, or tear notch can fail a formal recyclability assessment, because the mixed-material components disrupt automated sorting and contaminate the recycling stream.
This issue disproportionately impacts coffee and pet food brands. Resealable zippers and one-way degassing valves are non-negotiable functional features, but most standard off-the-shelf versions are manufactured from mixed plastic blends. Swapping the body film to mono-material while keeping standard accessories does not deliver full compliance - it simply results in a higher-cost bag with the same end-of-life limitation.
A fully compliant recyclable design requires every component to match the base film's polymer family. For coffee packaging, this means a mono-material PE degassing valve that preserves aroma integrity without introducing a foreign polymer. For resealable pet food and snack pouches, a full PE zipper replaces multi-material closures to keep the entire unit recyclable.

Lightweighting done wrong does more harm than good
There is a widespread misconception that PPWR rewards the thinnest possible film. In practice, the regulation prioritizes functional adequacy alongside waste reduction - packaging that fails to protect its contents does not count as a sustainable solution, even if it uses less material.
PPWR's emphasis on packaging reduction has led many brands to request the minimum feasible film thickness from suppliers. But excessive lightweighting backfires quickly: reducing thickness beyond a product's requirements erodes puncture resistance, seal strength, and barrier performance. For oily pet food, oxygen-sensitive coffee, or moisture prone snacks, this translates to spoilage, leaks, and product damage during transit. Wasted product creates a larger environmental footprint than a properly specified protective package, and it runs counter to PPWR's core waste-reduction goals. The regulation calls for the minimum necessary material use not the minimum physically possible.
Meaningful lightweighting comes from structural optimization, not arbitrary thickness cuts. A well-formulated mono-PE film with advanced barrier coating can often replace a heavier multi-layer structure, reducing overall material weight without compromising performance. LepuPouch engineers each recyclable food bag and specialty pouch to match specific product barrier and strength requirements, allowing brands to meet PPWR reduction targets without risking shelf life or transit damage.

The documentation gap that stalls shipments at the border
Many brands operate under the assumption that compliance paperwork is the sole responsibility of the EU importer or retail partner. In practice, customs and market surveillance authorities can request technical documentation at any point in the supply chain - and when documents are missing, the shipment is held, regardless of which party is technically accountable. Enforcement has been most proactive in Germany, the Netherlands, and Sweden so far, but requirements are expected to harmonize across the bloc through 2026 and 2027.
For flexible packaging, the most commonly requested documents include food contact safety certificates (FDA,EU10/2011), recyclability recognition statements, GRS certification for PCR products, and clear end-of-life handling instructions. There are well-documented cases of brands losing weeks of lead time because their packaging supplier could only deliver physical goods, not the supporting compliance paperwork.
The most reliable approach is to treat compliance documentation as a core purchasing requirement, not an afterthought. Before finalizing a bulk order, brands should confirm exactly which certificates and specification sheets a supplier can provide, from food contact safety reports to recyclability guidance and quality management documentation. Working with an EU experienced packaging supplier also reduces back-and-forth and last-minute document requests.
PPWR compliance cannot be boiled down to a single checkmark on a spec sheet. It requires a holistic review of every element of packaging - from raw material composition and functional components to printing inks, traceability systems, and supporting documentation.
Brands that adapt most smoothly are those that treat PPWR as a design priority, not a last-minute compliance task, and partner with suppliers that can map out the full compliance picture from the initial design phase. For brands seeking a reliable flexible packaging partner with proven PPWR-aligned solutions, LepuPouch offers low-MOQ custom production, zero-plate-fee digital printing, and 7–15 day production lead times.
