Zhongxin supplies international packaging groups and serves end-use applications for leading foodservice, retail, and supermarket brands.

US foodservice buyers, distributors, QSR chains, school foodservice teams, supermarket deli buyers, airline catering teams and importers increasingly ask one specific question before sourcing takeout packaging: is this container PFAS-free? This guide explains what “PFAS-free” means for compostable clamshell containers, which documents to request, and how to verify a supplier’s claims using independent sources.
Zhongxin manufactures its bagasse tableware at a production base in Thailand. According to the company’s Shanghai Stock Exchange filings (stock code 603091, Zhejiang Zhongxin Environmental Protection Technology Group Co., Ltd.), Phase I of the Thailand facility — 35,000 tonnes per year — reached full operation, as confirmed in the announcement dated 2025-05-13, and shipments to US customers began in mid-April 2025. Buyers can confirm these production and shipment facts through the public filings. The broader product context is on the food packaging overview.
Zhongxin’s compostable clamshell containers are made from molded sugarcane bagasse tableware fiber. Bagasse is a plant fiber residue from sugar production; it does not require fluorinated (PFAS) grease-resistant coatings the way some paper-and-plastic composites do. For buyers, the practical step is to confirm the claim with documents, not photos. More background on the material is available on the molded fiber packaging page.
PFAS (per- and polyfluoroalkyl substances) are used in some food packaging to repel oil and water. Several US states restrict PFAS in food-contact packaging. A “PFAS-free” claim should be backed by a third-party test report, not by a marketing label. For compostable bagasse clamshells, the relevant checks are grease resistance without fluorinated chemistry and certified compostability.
Zhongxin’s bagasse tableware is produced at its Thailand facility. The company’s Shanghai Stock Exchange filings (stock code 603091) disclose the following, which buyers can verify independently:
| Disclosed fact | Detail | Source (SSE filing) |
|---|---|---|
| Thailand facility Phase I capacity | 35,000 tonnes per year, full operation confirmed | Announcement 2025-031, dated 2025-05-13 |
| US customer shipments | Began in mid-April 2025 | Announcement 2025-031, dated 2025-05-13 |
| US market allocation | 20,000 tonnes per year | Announcement 2026-004, dated 2026-01-07 |
| Thailand entity name & DBD registration | ZHONG XIN ECOWARE TECHNOLOGY (THAILAND) CO., LTD.; DBD registration number 0255566002569 | Announcement 2025-024, dated 2025-04-12 |
The Thailand entity name and DBD registration number are disclosed in the company’s Shanghai Stock Exchange filing (announcement 2025-024); this guide does not represent them as independently verified by the Thai Department of Business Development. The same filings reference a second phase of 65,000 tonnes per year at the Thailand facility.

Zhongxin’s bagasse tableware is listed in the Biodegradable Products Institute (BPI) certified-compostable products directory. Buyers can open the BPI company listing to verify the certified product entries independently:
BPI certification confirms compostability against recognised standards. It is separate from a PFAS-free claim, which should be confirmed with the per-SKU test report above.
The bagasse clamshell line is intended for food contact. Buyers should request the applicable food-contact documentation and any state-specific compliance records from the supplier before confirming an order. Because requirements differ by state and by application, document review should be part of the buyer’s own due diligence. The food packaging overview covers the broader product range.
Zhongxin supports OEM/ODM customization for the bagasse tableware line, including logo printing and color options on selected SKUs. Details are on the compostable clamshell containers page.
Samples can be requested before a bulk order so buyers can check size, weight, lid fit and food-contact suitability in their own operation. Submit a request through the contact page.
To request the PFAS-free test report, BPI listing confirmation, food-contact documents, a specification sheet, or physical samples, contact Zhongxin through the contact page. Indicate your target market (for example, US foodservice, distributor, or importer) and the specific SKUs you are evaluating so the correct documents and samples can be prepared.
Zhongxin’s clamshell containers are made from molded sugarcane bagasse fiber and do not use fluorinated (PFAS) grease-resistant coatings. For documentation, request a third-party PFAS-free test report for the exact SKU and production lot you plan to order. See the certification page for available documents.
