Jiangsu Sanfame Polyester Material Co.,Ltd. (600370.SS): How It Works

• Primary revenue drivers: sale of staple fibers, filaments, bottle-grade polyester chips, polyester film, and recycled polyester fibers.
• Vertical integration: in-house PTA/PTMEG sourcing and polycondensation to control feedstock costs and margins.
• Capacity-led economics: large-scale continuous polymerization and spinning lines reduce unit costs and support contract supply to major textile and packaging customers.

• Staple fibers and filaments - textiles, industrial yarns, nonwovens.
• Bottle-grade polyester chips - PET for beverage, food, pharmaceutical, cosmetic packaging.
• Polyester film - packaging, printing substrates, optoelectronic films (base for functional coatings).
• Recycled polyester fibers (rPET) - from post-consumer and industrial scrap, sold into apparel and packaging markets.

• Commodity polyester chips sold in bulk under long-term and spot contracts - pricing linked to PTA/MEG feedstock and global PET demand.
• Value-added fibers and filaments sold at premium pricing to textile brands and industrial customers.
• Specialty film sold to converters and electronics suppliers commanding higher margins than commodity chips.
• Recycled products sold at sustainability premiums and often supported by offtake agreements with brand owners seeking lower-carbon materials.

• 1.5 million ton/year green multifunctional bottle chip project - designed to scale rPET and green-PET supply for the packaging sector, targeting beverage and FMCG customers and enabling premium pricing for certified low-carbon chips.

• Customers: domestic textile mills, global apparel brands (for rPET), beverage and packaging converters, printing/film converters, electronics component suppliers.
• Sales channels: direct industrial contracts, spot market sales, long-term offtake agreements for specialized grades, joint ventures with converters for integrated supply.
• Pricing dynamics: margins cyclically linked to PTA/MEG and global PET demand; specialty film and recycled lines reduce margin volatility and capture sustainability premiums.

• Capex focus: green bottle-chip project and recycling upgrades to increase higher-margin sustainable product mix.
• Cost controls: feedstock integration, energy efficiency in polymerization and spinning, scale economies from larger continuous lines.
• Product mix upgrades: move from commodity chips to functional films, specialty fibers, and certified low-carbon PET to improve blended margins.

• Market capitalization of 8.28 billion CNY (12‑Dec‑2025) reflects investor expectations of growth from the green bottle-chip expansion and rising rPET adoption.
• Sanfame markets itself as a supplier able to meet both volume needs (commodity chips/fibers) and sustainability-driven demand (recycled and green-designated chips and fibers).
