Does your ISCC PLUS certification support sustainable packaging claims in the EU?

Yes — with a clear understanding of how ISCC PLUS relates to current and upcoming EU regulations.Our ISCC PLUS certification (Certificate No. ISCC-PLUS-Cert-DE100-22099125, issued by SGS Germany, valid through September 2026) covers us as a converter under the mass balance chain of custody method. This means we can provide verified, third-party audited documentation tracing certified bio-based or recycled content in our materials — which directly supports your brand's sustainability claims. [1]Specifically, this certification enables: Supply chain transparency documentation for your ESG and sustainability reporting Verified recycled or bio-based content claims on your packaging, backed by an independent audit Alignment with major EU voluntary sustainability frameworks and buyer procurement requirements [1] On EU regulatory compliance (PPWR) — and how ISCC PLUS fits inThe EU Packaging and Packaging Waste Regulation (PPWR) (Regulation EU 2025/40) entered into force on 11 February 2025, with most provisions applying from 12 August 2026. [3][4]What PPWR requires: By 2030, certain packaging categories must contain minimum recycled content, for example: 10% for non-PET contact sensitive packaging 30% for single-use plastic beverage bottles 35% for other plastic packaging [5] Companies must be able to verify and prove recycled content claims [4] Where ISCC PLUS stands: PPWR does NOT explicitly mention or mandate ISCC PLUS — or any specific certification scheme However, ISCC PLUS is currently one of the most widely accepted, industry-recognized certification schemes for demonstrating recycled and bio-based content under the mass balance model [1] It serves as a credible, third-party audited tool that can help you meet PPWR's verification requirements. As stated in the ISCC Global Sustainability Conference 2026 recap: "Chemical recycling is being recognised under defined mass balance rules … and mandatory third-party certification like ISCC PLUS." [2] (Note: "like" indicates an example, not an explicit mandate in the regulation text.) In short:ISCC PLUS is not required by PPWR, but it is the most commonly used and trusted "measuring stick" for proving recycled content today. PPWR tells you what to prove (e.g., 10% recycled content). ISCC PLUS helps you how to prove it.Important additional considerations Rules still in development: PPWR's specific delegated and implementing acts — including detailed rules for calculating and verifying recycled content — have not yet been published. No certification scheme can currently claim formal "PPWR approval." As noted by industry sources, "the official methodology for calculating and verifying recycled content under the PPWR will be established in upcoming implementing acts." [5] Food contact compliance (if applicable): ISCC PLUS certification alone does not guarantee compliance with EU food contact regulations (e.g., Regulation (EU) No 10/2011 for plastics). [6] Additional validation is required. Updated ISCC PLUS scheme (July 1, 2025 onward): ISCC PLUS now operates under its own independent system document. Our certificate remains valid and reflects current requirements. Bottom lineISCC PLUS mass balance certification directly supports sustainable and recycled content claims in the EU today. It is well-aligned with the direction of PPWR and widely accepted by industry as a credible verification tool. [1][2][5]However, because ISCC PLUS is not explicitly named in PPWR, and implementing rules are still being finalized, we recommend validating specific compliance requirements with your EU regulatory team as detailed rules are published.We are happy to provide our certificate, sustainability declarations, and supporting documentation upon request.References No. Source Link [1] ISCC System – Plastics and Packaging Market Page https://iscc-system.org/about/markets/plastics-and-packaging/ [2] ISCC Global Sustainability Conference 2026 Recap https://iscc-system.org/recap-of-the-lobal-sustainability-conference-2026/ [3] UK Government – PPWR Overview https://www.business.gov.uk/campaign/europe/european-union-eu-regulations/eu-packaging-and-packaging-waste-regulation-eu-ppwr/ [4] EU Commission PPWR FAQ & Guidance (via GLOBALNORM) https://compliance.globalnorm.de/en/product-compliance-news/detail/eu-packaging-faq-and-guidance-published/ [5] Mondi Group – Recycled Content in Plastic Packaging (referencing PPWR 2030 targets) https://www.mondigroup.com/products-and-solutions/packaging-and-packaging-waste-regulation/recycled-content-in-plastic-packaging [6] EUR-Lex – EU Regulation (EC) No 10/2011 (Food Contact Materials) https://eur-lex.europa.eu/legal-content/EN/TXT/DOC/?uri=PI_COM:C(2025)1085

What is the lead time for production?

Standard lead time for custom-printed bags is 25–35 days following sample approval. Shorter lead times may apply to standard or non-printed rolls. Final production schedules will be confirmed upon order confirmation.

Can you print my logo on the bags?

Yes. We offer water‑based flexo printing up to 4 colors on both sides. Pantone matching is available. Custom printing is subject to MOQ, and we provide pre‑production samples for approval.

What certifications do your compostable bags hold?

All our compostable bags are certified to international standards: BPI (ASTM D6400) for North America, EN13432 / Seedling logo for Europe, OK compost HOME for home composting, and AS4736/AS5810 for Australia. You can request the certificates for each product.To view our full range of certifications, please visit: https://www.torisegroup.com/certificate.htm

Is it important for bio-based plastics to be recyclable?

Yes, it's important for plastics to be made in a way that can be recycled easily because it helps protect the environment. This is also in line with quotas set by laws. Manufacturers are encouraged to design their packing as sustainable as possible.

Are bio-based plastics always 100% bio-based?

Sometimes bio-based plastics are not completely made from plants. Bio-based content in these plastics can be determined by using certain standards such as CEN/TS 16137 for polymers and EN 16785-1 for products. This content is usually shown as a percentage.

Should I be Placing Single-use, Non-compostable Plastic Bags in the Recycling Bin?

As policies are different, contact your local government or recycling company to confirm whether this particle is allowed. In the recycling stream, loose plastic bags are challenging to manage and can block machinery. Single-use bags may be recycled by certain recycling firms if they are packaged tightly and knotted.  

What are Biobased Plastics?

Rather than being produced from oil or natural gas, biobased plastics are generated from plant resources. One may believe that this kind of plastic must biodegrade because it is derived from plants. Nonetheless, biobased plastics can be engineered to have the same structural integrity as petroleum-based polymers, and if this is the case, they will have an equivalent environmental shelf life. Biobased plastics can be designed to be compostable or biodegradable, just like petroleum-based plastics. 

How long will Home Compostable products take to biodegrade?

It generally depends on the plastic thickness and the home temperatures, the home compostable product can start biodegrading within 4-8 weeks and up to 1-2 years. 

What happens to Compostable Packaging in landfill?

In a landfill, compostable packaging behaves like an organic waste. If exposed to moisture and oxygen in the top layers, it will compost over time. However, if buried deep without oxygen and moisture, it will remain inert.

What is left behind after composting compostable bioplastic packaging?

After composting, the compostable bioplastic packaging results in water, CO2, and biomass, which enrich the soil. The compost is nutrient-rich, environmentally safe, and free from micro-plastic or pollutants. Our materials and finished products undergo rigorous certification to ensure their safety and compliance with standards.

What is difference between 'OK Home Compost' and 'OK Industrial Compost' ?

Here are the differences between both:(1) OK compost  INDUSTRIAL (EN13432): Materials carrying this label compost only in industrial composting facilities, where higher temperatures between 55 to 60°C facilitate the breakdown process. (2) OK compost Home: Products with this label compost at lower temperatures, making them suitable for composting in home garden compost stacks as well as industrial composting facilities.

Do you provide After-sales Service and Warranty Service?

In order to protect the rights and interests of our customers and improve your satisfaction, we provide a series of services. These services usually include after-sales consultation, product warranty, return and exchange services, etc., aiming to provide you with a better experience after purchase, thereby enhancing your trust to us and long-term cooperation.

How do These Products Help the Environment ?

In addition to other businesses and homes, the food service industry uses single-use plastics and foam products. Petroleum feedstocks, a non-renewable resource, are used to make the majority of single-use plastic and foam items. Furthermore, the majority of single-use plastics wind up in landfills. Because some of the products we sell can be recycled or composted, they lessen the quantity of single-use items that end up in landfills and our dependency on plastics.Our compostable products are better for the environment because they are sourced from annually renewable resources such as sugarcane bagasse, cornstarch, or wheat straw, and they can be composted in a commercial compost facility, where they will break down within 180 days. These facilities may not be available in all areas.
