Automatic Bagging System for PVC Resin Granule Packaging
The chemical packaging industry handles a broad variety of powders and granules, each with its own flow characteristics, dust behavior, and safety requirements. Packaging lines in this sector need stable filling performance, reliable sealing, and smooth handling of different bag types to keep production efficient and consistent.
- Product name (Material): PVC resin (polyvinyl chloride resin)
- Material form: Granular
- What we provided: Servo gravity dual-scale system + transition hopper + 3CM automatic open-mouth bagging machine + GKS sealing machine
A PVC resin manufacturer selected our automatic bagging system for packaging PVC (polyvinyl chloride) granules. The solution combined a servo-driven dual gravity scale, transition hopper, 3CM-PS automatic open-mouth bagging machine, and GKS-13 paper bag heat-sealing and stitching unit. This configuration ensured high-speed operation, compatibility with the required bag types, and full alignment with the customer’s performance and material standards.
Project Requirements
The packaging line needed to achieve an output of 800 bags per hour with a 25 kg filling weight. The specified bags were M-type multi-wall kraft paper sacks with a composite structure (three-in-one). The system also had to handle two empty bag sizes: 860 × 450 mm and 890 × 460 mm, and a filled bag dimension of 700 × 460 × 150 mm. All product-contact components were required to be stainless steel, while the remaining machine frame could be carbon steel. Fasteners such as screws and nuts needed to be stainless steel. Several electrical components had to be supplied in designated imported brands to ensure compatibility with the customer’s existing production environment.
Our Solution
A 3CM-PS automatic bagging machine with a capacity exceeding 800 bags per hour was configured for this project, fully matching the customer’s bag type and size specifications. All contact points were manufactured in 304 stainless steel, while the main frame used carbon steel for durability and structural integrity. This setup ensured hygienic handling of the material, stable filling performance, and reliable operation in line with the customer’s technical, structural, and integration requirements.
