中文Recycling has a quiet enemy: everybody measures it differently. A pouch deemed recyclable by one company’s in-house test can fail another’s. In Japan’s flexible-packaging sector, two of the biggest ink makers just decided that nonsense has to stop — and they built a rulebook to prove it.
The artience Group, through its packaging-solutions subsidiary Toyo Ink, and DIC Corporation have developed a common industry protocol that standardises how deinking and debonding are tested, evaluated, and reported for the material recycling of flexible film packaging in Japan. They say it is the first such protocol in the industry, and they are inviting the whole domestic supply chain to adopt it.
Why “recyclable” needs a dictionary
Flexible packaging is everywhere — food, daily goods, pharmaceuticals. It is light, protective, and efficient to ship. But it is also a sandwich of films, printing inks, and laminating adhesives. To recycle it properly, you must remove the printed ink (deinking) and separate the layered films (debonding). Do those badly and the recycled plastic comes out contaminated and useless.
In Japan, those evaluations used to run on each company’s own proprietary test conditions and criteria. The result? You could not compare results across firms or materials, which made it nearly impossible to assess recyclability at the design stage or share information cleanly down the chain. For a country positioning the circular economy as a growth strategy — and watching resource prices swing and geopolitical risks rise — that ambiguity was a real drag on progress.
What the protocol actually fixes
The protocol has three core elements, and together they are refreshingly practical:
First, test procedures. It spells out the equipment, conditions, material handling, and steps so results are reproducible in Japanese testing environments. No more “trust me, we tested it.”
Second, evaluation criteria. It sets objective standards for how well deinking and debonding worked and how good the resulting recycled plastic is. Opinion becomes measurement.
Third, a reporting format. It standardises test conditions and results into one unified layout, so converters, brand owners, and recyclers can actually talk to each other without a translator.
Who benefits, and how
The companies are explicit that this is not a lab curiosity. Converters can more easily choose printing and processing conditions and materials that prioritise recyclability. Brand owners can pick highly recyclable packaging based on objective data instead of supplier claims. Recyclers can set processing conditions to match material traits, improving the quality of what comes out the other end.
That last point is the whole point of a circular economy: not just collecting plastic, but making the collected plastic good enough to use again.
The honest path forward
artience and DIC are not pretending the protocol is finished. They plan to keep refining it using real packaging materials and recycling processes from the Japanese market, and they are actively courting other stakeholders to adopt it. The goal is for it to become the de facto standard for recyclability assessment in Japanese flexible packaging — from design and manufacturing through collection and recycling.
They will showcase it at Tokyo Pack 2026, 14–16 October, at Tokyo Big Sight, under the theme “ReLoop – Drawing the Future with Circulating Materials.” Toyo Ink’s stand (East Hall 2, 2N10) will present both sustainable solutions and colour innovation.
For the rest of the world, the lesson is portable. Circular packaging will not scale on good intentions. It scales on shared, boring, rigorous standards that let everyone in the chain trust the same number. Japan’s ink makers just handed the industry a template — and dared the rest to use it.
The protocol’s significance reaches beyond Japan. Every region wrestling with plastic waste faces the same measurement mess — Europe under PPWR, North America under state mandates, Asia under varied frameworks. A Japanese standard is not directly transferable, but the template is: agree the test, agree the bar, agree the report. Without that, “recyclable” remains a marketing word rather than an engineering fact.
For brand owners, the move is a prompt to ask harder questions of suppliers everywhere. Demand the data behind the recyclability claim. If your converter cannot show a standardised test result, you are carrying risk you do not understand. The companies that get comfortable with that scrutiny — and the ink makers handing them the ruler — will define what circular packaging actually means.
Standards rarely make headlines, but they make markets. Without a shared way to measure, every recyclability claim is a negotiation, and negotiations are where good intentions go to die. By publishing a method anyone can adopt, artience and DIC have done the unglamorous work of turning a slogan into a specification. That is how circular packaging actually scales — not through one heroic material, but through thousands of comparable, auditable tests that let a brand trust the number on the spec sheet.
