When a converter, brand owner or distributor begins sourcing fully biodegradable resin, the first question is rarely "does PBAT exist?" The question that decides the order is different: who can deliver the same pellet, batch after batch, with the technical support and documentation my customers will accept? That is the question Gansu Mogaojuhe Environmental Protection New Material Technology Co., Ltd. was built to answer.
Based in the Yongchang Economic Development Zone of Jinchang City, Gansu Province, the company is a wholly-owned subsidiary of A-share listed Mogao Co., Ltd. It produces fully biodegradable virgin pellets — PBAT and PBS — together with PLA blended modified materials and biodegradable masterbatches, and it supports downstream processing of mulch films and packaging products. Annual virgin polyester capacity stands at 20,000 tons, with a premium product rate of 99%. For buyers who need a supplier with a real plant behind the quotation, that is the starting point.
Fully Biodegradable Virgin Pellets: PBAT and PBS
The core of the product range is virgin resin, not reprocessed material. PBAT provides the flexibility and toughness that film applications demand, while PBS brings complementary performance for converters building a portfolio of biodegradable grades. Because both are produced as virgin pellets, downstream manufacturers can plan their formulations around predictable melt behaviour, consistent pellet geometry and stable lot-to-lot indicators rather than compensating for incoming variation.
Behind that consistency is an in-house professional testing laboratory. Every production run can be checked against defined indicators before it is released, which is what makes a declared 99% premium product rate meaningful in practice: it is a quality discipline applied to shipments, not a line in a brochure.
Modified Compounds and Masterbatches Built Around Your Process
Very few converters can run raw PBAT straight from the silo. Film lines, injection moulders and agricultural film producers each need a different balance of stiffness, tear strength, slip and processability. Gansu Mogaojuhe supplies both the base resin and the engineered compound, with customised modified formulas developed for:
Film blowing — grades tuned for bubble stability, drawdown and roll quality on conventional blown film equipment.
Injection molding — compounds balanced for flow and toughness in rigid and semi-rigid parts.
Agricultural mulch films — formulations developed for the mechanical demands of field deployment and the degradation behaviour growers expect.
Food packaging bags — compounds designed for the film strength and appearance that retail packaging requires.
Alongside these, PLA blended modified materials and biodegradable masterbatches allow converters to build colour, additive or performance functionality into a formulation without rebuilding the whole recipe. The company also owns independent patented modification technologies; its portfolio includes a granted utility model patent (ZL 2023 2 1879648.1, authorised 27 February 2024) covering a tail gas treatment device for PBAT and PBS polycondensation — a reminder that process engineering and environmental control sit alongside formulation work in this business.
Toll Modification Processing: Your Material, Our Formula
For distributors and packaging producers who already hold PBAT stock or have committed to a resin source, the company accepts toll modification processing across the full range of PBAT materials. You supply the base polymer; the technical team applies a modified formula matched to your target application.
The service is deliberately flexible. Fill and toughening formulas can be adjusted on demand, so a single base resin can be turned into several saleable grades for different end uses. Small-batch sample trials allow a formulation to be validated before commitment, and long-term mass processing orders follow once the specification is fixed. With mature processing techniques and years of operating experience on the same equipment, the transition from trial to volume production is a matter of scheduling, not re-development.
Quality, Certifications and Cost Control
Three factors support the commercial case for sourcing here:
Certification coverage. The company holds a full set of national standard certifications and biodegradation accreditations — the documentation overseas buyers need when their own customers ask how a material claim is substantiated.
Cost structure. Located in a region with favourable access to raw materials, the company tightly controls production costs through geographical advantage rather than through shortcuts in specification. For distributors managing landed-cost margins, that difference compounds across container volumes.
Verified stability. The in-house laboratory closes the loop between production and shipment, keeping product indicators stable enough for converters to lock in their own process parameters.
A Track Record You Can Trace
The company was registered on 30 September 2018. Construction of the Phase I 20,000-ton PBAT project began on 5 August 2019; the plant achieved a successful trial run at the end of December 2021 and moved to full-line mass production on 18 March 2022. In 2023 the R&D programme delivered a breakthrough with PBST copolyester laboratory and pilot-scale trials completed jointly with research institutes. In 2024, capacity and qualifications were further strengthened. A buyer assessing supply security can read this as a plant that has already passed through commissioning risk and is now operating in a steady production phase.
Where These Materials Are Used
The end markets are the ones under the most regulatory and consumer pressure to move away from conventional plastics: agricultural mulch film programmes, shopping and carrier bags, food packaging, mailer and express packaging, compostable serviceware and rigid injection-moulded items. In each case, the value to the converter is not simply a biodegradable label — it is a resin that runs on existing equipment with an adapted formulation and a supplier who can support the trial-to-production path.
An Industry Note for Buyers
Demand for biodegradable resin is being pushed by single-use plastics regulation in many markets and pulled by brand commitments to recyclable or compostable packaging. That combination is producing two pressures on the supply side: converters need grades that fit their existing lines, and they need documentation that survives customer audits. A supplier who offers base resin, custom modification and in-house testing under one roof reduces the number of parties a buyer must manage — and reduces the risk that a formulation performs in the lab but not on the line.
Start With a Sample
Rather than asking buyers to commit on a datasheet alone, the company supports small-batch sample trials so that film blowing, injection molding or mulch film performance can be assessed on your own equipment. From there, volume supply or toll processing can be scoped against your specification.
