From PP resin to finished bag — ZONGYE controls every step in-house. Food-grade, UN-certified, anti-static and custom FIBC solutions, backed by a documentation package built for EU and global compliance.
IN-HOUSE PRODUCTION · 300+ MACHINES
Tangshan Zongye Packaging Co., Ltd. is an integrated industrial packaging manufacturer founded in 2021 (with production roots going back to 2013). We design, produce and export mid-to-high-end FIBC bulk bags, PP woven sacks and liners for chemical, new-energy, food, agriculture, mining and hazardous-material applications.
We don't organise bags by how they are woven — we start from your material, then specify structure, liner, loops and electrostatic rating. Browse the series most relevant to your product.
Powders and granules with moisture, leakage and static risks. Anti-leak seams, liners and Type C/D options.

One fabric folded into a U plus two side panels. Lowest cost, highest output, square shape.
Four sewn panels. Dimensionally stable, holds shape under load — ideal for dense minerals.
Woven as one tube, no side seam — the best defence against fine-powder leakage.
Internal PP baffles keep the bag square when filled — up to 15–20% more containers per shipment.
Most competitors quote gram-weight and price. We win on structures you can't get elsewhere, documents buyers actually need, and traceability to the source.
Form-fit liners, single-loop integrated lifting, hollow-board inserts, built-in pallets, lattice bottoms. Eight patented structures — when others say "we can't", we send a drawing.
Not "we comply" — but migration, heavy-metal, MOSH/MOAH and PPWR ten-element files. The packet European buyers ask for, ready to attach to the RFQ.
Our "Quality Passport" traces every batch to raw-material lot, machine, shift and inspector. A failure can be pinpointed in minutes, not weeks.
Every non-standard order follows a documented process with a deliverable at each step — no verbal promises.
