Import Automatic Four Sides Sealing & Packing Machine — Buy in wholesale FOB from Supplier in China

The SB800W is an automatic four-side sealing and packing machine manufactured by Ruian Yidao Machinery Co., Ltd. in Zhejiang Province, China. It produces hermetic four-sided seals on flexible packaging, with an adjustable speed control system and sensor-guided sealing mechanism. The control panel is designed for direct operator access, and the frame footprint is compact for factory floor efficiency. The machine processes flexible films and laminates into sealed pouches or sachets.

Standard four-side sealers in this class typically achieve sealing temperatures between 120 degrees Celsius and 200 degrees Celsius depending on film specification, with heat-seal jaw pressure adjusted via pneumatic or cam-driven systems. The SB800W uses formed film from roll stock, with common seal widths ranging from 5 mm to 10 mm as typical for the category. Seal integrity is maintained through constant heat or impulse sealing, with cooling bars following the seal line to prevent deformation. Film transport is usually handled by a combination of draw belts and forming shoulders, with registration sensors for print alignment.

This configuration serves food and beverage producers packaging snacks, condiments, and powdered ingredients, as well as pharmaceutical firms requiring barrier protection for tablets and capsules. Consumer goods manufacturers use four-side sealers for single-serve cosmetics and samples. Buyers should confirm with Ruian Yidao Machinery the exact film thickness range, maximum web width, and output speed in cycles per minute before specifying the machine for a line. Packaging and Incoterms are not stated in the source data and require direct supplier confirmation.

Ruian Yidao Machinery Co., Ltd. is based in Feiyun Industrial Zone, Ruian, Zhejiang Province, China, postal code 325200. The company operates within the Ruian machinery manufacturing cluster, a region known for packaging and printing equipment production. The supplier holds a harbor trust tier on the platform, with a response rate of 0.00 percent and an average response time of zero hours recorded. These engagement metrics suggest limited active communication through the platform channel, so buyers should establish direct contact outside the platform to assess responsiveness.

The listing describes the SB800W four-side sealing machine as the supplier's offering, but provides no information about factory size, year of establishment, annual revenue, export markets served, or client references. No ISO or CE certificate numbers are supplied, and no audited manufacturing capabilities are documented. Buyers should request a company profile, factory audit report, and reference installations before committing to a purchase order. Video verification of the machine in operation is advisable given the lack of third-party certification detail in the source material.
