Import Doybag Fill Seal Machine — Buy in Bulk from Supplier in China

The Doybag Fill Seal Machine offered by Unionpack International Inc. is a fully automated system designed to fill and seal pre‑made Doybags in a continuous line. Model RZ8‑200 features a stainless‑steel 304 frame and a frequency‑conversion motor drive, delivering a total power of 2.3 kW at 380 V three‑phase. The equipment can handle bag dimensions from 70 mm to 200 mm in width and 100 mm to 300 mm in length, with a filling range of 5 g to 1500 g per pouch. Packing speeds of 20  -  45 bags per minute are achieved depending on product viscosity and target weight.

Key components include a SUS304 stainless‑steel contact surface, imported plastic bearings that operate without oil, and a vacuum generator from SMC for efficient air removal. The control system uses a PLC with a dual‑language touch screen, providing precise weight control with an accuracy of ±1 % and a typical error of 1 % of set weight. The machine accommodates heat‑sealable films such as PA/PE, PET/PE and AL‑film, reflecting standard industry material compatibility. Standard maintenance intervals involve quarterly lubrication checks of the bearings and annual calibration of the weighing system.

Target users are manufacturers of liquid or semi‑solid products, including sauces, cosmetics and pharmaceuticals, that require hygienic, high‑speed pouch filling. Unionpack International Inc. notes that the system can operate unmanned, with automatic alarms for filling or sealing failures, which reduces labour costs. Shipping terms are not detailed in the listing, so buyers should confirm FOB or CIF options as well as the preferred payment method, typically L/C or T/T. Prospective purchasers are advised to verify the machine’s compliance with GMP standards and request installation and training support.

Unionpack International Inc. is situated in the Economic Development Zone, Ruian, Zhejiang, China (postal code 325200). The company carries a harbor trust tier, indicating verification through the platform’s trust system, but its public response rate is recorded as 0 % with no average response time logged, suggesting that communication may need to be initiated proactively.

The firm specialises in engineering high‑speed filling and sealing equipment for flexible pouches, with the RZ8‑200 model highlighted in the listing. Although production capacity and client references are not disclosed, the supplier emphasises features such as stainless‑steel construction, oil‑free bearings and a PLC‑based control interface. Potential buyers should request detailed technical drawings and after‑sales support information to assess suitability.
