Where Is the Most Effective Placement of VCI Powder in Export Packaging?

Rust-inhibiting particles work by releasing VCI, which forms a protective shield inside the packaging, isolating moisture and corrosive agents. Therefore, their placement is crucial—the molecules must be evenly distributed throughout the packaging to reach all metal surfaces.

Generally speaking, placing china vci powder for metal in these three locations yields the best results:

1. Close to the metal surface—The china vci powder for metal should be placed as close to the product as possible so that the released rust-inhibiting molecules can immediately reach the metal and form a protective layer.

2. In the center of the packaging—If the box is large, place china antirust powder in the center and corners to ensure even distribution of the rust-inhibiting molecules, eliminating any dead spots.

3. In the gaps within sealed containers—china vci powder for metal works best in sealed environments, so they should be placed before the packaging is sealed, avoiding areas with potential exposure to moisture, such as areas at the bottom where water could accumulate.

Speaking of this, I recall a client of ours who exports precision machinery. They previously used standard rust-inhibiting oil. The result was a thick coat of oil, which gave the packaging a shiny, glossy appearance. However, upon unpacking the packaging on-site abroad, some parts inside were still yellowed and rusted. Later, they tried our china vci powder for metal and made only a minor adjustment to the export packaging—placing pellets in a few strategic locations. After several months of shipping, the product was still in good condition when unpacked, prompting them to place more orders.

Our china antirust powder is compact, releases evenly, is non-toxic and odorless, and can be used with a variety of packaging materials, such as anti-rust film, bags, and paper. china antirust powder is not only suitable for export packaging but also for long-term storage of products, such as machined parts, precision bearings, copper and aluminum parts, for rust protection.

CVCI has its own large, modern factory capable of producing a variety of protective materials, including china antirust powder, anti-rust film, paper, and oil, ensuring stable production capacity and timely delivery. We also have a 4,000-square-meter laboratory accredited by the China National Accreditation Service for Conformity Assessment (CNAS). Equipped with advanced equipment, such as a salt spray tester, we simulate various transportation and storage conditions. This allows us to repeatedly test our china antirust powder and other anti-rust products to achieve optimal rust prevention results.

Our anti-rust granules and other rust-preventing products are now widely used in numerous industries, both domestically and internationally, including automotive parts, military equipment, aerospace, new energy equipment, metallurgical sheet metal, and electronic components. Our long-term partners include well-known companies such as Volkswagen, BMW, GM, Mitsubishi, Chery, Dongfeng, Sinotruk, Weichai, Huawei, and Gree. Many clients first approach us because their export products have rusted during transportation. After working with us, they readily return for repeat orders, sometimes even establishing long-term partnerships.

So, if you're exporting metal products, a small package of china antirust powder, with the right placement and proper handling, can help protect your goods from rust during the long journey, ensuring they arrive looking like new upon arrival.
