Suzhou Keysun Packaging Co., Ltd

Suzhou Keysun Packaging Co., Ltd operates in Suzhou, China and currently lists five active products. The catalogue covers volatile corrosion inhibitor (VCI) solutions across four top categories: Masterbatch, Industrial Sheets, Corrosion Inhibitor and Plastic Foil. Each product appears under the VCI label - VCI Masterbatch, VCI Paper, VCI Powder, VCI master batch and VCI Film - reflecting the company’s focus on chemical additives and protective packaging materials. The product list aligns with HS‑code chapter 38 (chemical products) that is commonly used for VCI chemicals and related polymer blends. The supplier is classified as an imported tier “harbor” within the platform’s trust hierarchy.

The VCI Masterbatch and VCI master batch entries refer to the same polymer‑based additive, typically supplied in granule or pellet form for extrusion. VCI Powder is a fine crystalline additive used for bulk coating or blending, while VCI Paper and VCI Film are sheet‑type products that incorporate the inhibitor into cellulose or polymer films. All five items are positioned for metal protection applications such as automotive parts, hardware and construction fasteners. The catalogue does not provide specific HS numbers for each line item, so the description remains within the broader chemical product classification.

The catalogue’s VCI Masterbatch products are polymer concentrates that usually contain 2 % - 5 % active corrosion inhibitor by weight, compatible with polypropylene, polyethylene or polyester matrices. In the broader industry, masterbatch grades are graded by inhibitor loading, melt flow index of the base polymer, and thermal stability, with typical melt flow indices ranging from 2 to 30 g/10 min. VCI Powder is supplied as a crystalline salt, often meeting purity levels of 98 % - 99 % and particle sizes between 50 µm and 200 µm, suitable for blending into resins or for direct application on metal surfaces. VCI Paper and VCI Film are sheet products; standard industry specifications include thicknesses of 30 µm - 120 µm for film and grammage of 70 gsm - 150 gsm for paper, with inhibitor loadings of 0.5 % - 3 % by weight. These grades meet typical automotive and industrial corrosion‑prevention standards, such as ASTM G48 for corrosion testing.

Industrial sheet and plastic foil categories, although not detailed in the catalogue, generally follow ISO 9001 quality management and may be produced in standard roll sizes of 1 m × 100 m for film and 1 m × 50 m for sheet, packaged in shrink‑wrapped bundles for export.
