About Us

LINYI DONGYI IMPORT&EXPORT CO.,LTD. is the exclusive foreign trade subsidiary of Shandong Donglai Packaging Group Co., Ltd. Headquartered in Linyi, Shandong-China's renowned "Logistics Capital"-the group entered the plastic packaging industry over a decade ago, initially focusing on PP woven bag manufacturing. Through years of continuous expansion, we have built a fully integrated industrial chain covering wire drawing, circular weaving, color printing, film lamination, and finished product processing. We have since diversified our portfolio to include LLDPE stretch film, agricultural weed control fabric, and square bottom valve sacks. This dedicated export subsidiary was established to secure independent import & export customs clearance qualifications. Today, we have evolved into a comprehensive packaging manufacturer integrating R&D, mass production, and global trade.

Our Factory

We own a self-built standardized industrial park spanning 108 mu, with a total production workshop area of 40,000 square meters. The facility is systematically divided into independent production workshops, raw material warehouses, finished goods warehouses, and a professional quality inspection laboratory. We operate on a fully self-controlled production model with zero outsourcing, supported by over 300 on-site employees including professional R&D and foreign trade sales teams. Standardized site management and full-process quality tracking enable us to efficiently handle both large-volume bulk orders and small-batch customized orders in parallel.

We supply three major series of packaging products. The first is our core PP woven series, including plain woven bags, color woven bags, laminated woven bags, ordinary valve bags, square bottom valve bags, agricultural mesh bags, and FIBC bulk jumbo bags-all available for customization in size, thickness, color, printing pattern, and lamination process. The second is PE stretch film, covering hand stretch film, machine stretch film, colored film, and large raw film jumbo rolls, with customizable width, thickness, weight, color, and packaging method. The third is agricultural weed control fabric in black and green types with various weights and apertures, supporting custom width, thickness, length, hole size, and hole arrangement.

Our products serve a wide spectrum of industries. PP woven bags are widely used in agriculture for packing grain, fertilizer, seeds, fruits, and vegetables; in construction and chemicals for sub-packaging cement, mineral powder, plastic pellets, and chemical raw materials; in the food industry for food-grade laminated packaging of rice, flour, and feed; and for general storage and seaworthy transport packaging of daily wholesale goods.

PE stretch film is specially designed for the logistics and transport industry, widely used in pallet wrapping, cargo bundling, and warehouse storage to protect goods from scratches, moisture, and breakage during land, sea, and air freight. It is also commonly applied in manufacturing assembly lines for semi-finished product protection and in the paper, textile, and food & beverage industries for roll wrapping and palletized cargo stabilization.

Agricultural weed control fabric is mainly laid on farmland and in orchards to suppress weeds, retain soil moisture, and prevent soil erosion. It is also widely used in greenhouses and nurseries to maintain clean growing beds, in landscaping and garden projects for decorative ground cover, and in orchards and cash crop plantations for row mulching to improve fruit cleanliness and harvest efficiency.

We hold a complete portfolio of authoritative certifications. We have passed the ISO 9001 Quality Management System Certification, obtained the AAA Enterprise Credit Rating and the AAA Contract-Abiding & Trustworthy Enterprise Certificate, and been recognized as a CCTV Certified Enterprise and a 1688 Super Factory. In addition, we hold an Independent Import & Export License that grants us self-operated customs clearance for global trade. These credentials fully demonstrate our commitment to quality, integrity, and compliance.

We are fully equipped with a complete range of automated production machinery, including 4 wire drawing extruders, 300 circular looms, multi-color flexographic printing machines, color-printing & laminating machines, automatic cold-cut square bottom forming machines, heat-sealing equipment, 3 PE stretch film extrusion lines, large-width circular looms dedicated to weed control fabric production, slitting & rewinding machines, and perforating machines for precise aperture punching.
