As we all know, industrial products during production, transportation, and storage, due to contact with air, moisture and other natural environmental factors, can experience corrosion. Corrosion not only affects the quality of the product, but also causes great losses to the company and the production line. The emergence of rust-proof bags provides an effective solution to this problem.


I. Definition and working principle of rust-proof bags


Rust-proof bags are a new type of packaging material widely used in the packaging industry, which can effectively prevent industrial metal products from corrosion, oxidation, and contamination during storage. The main component of the rust-proof bag is polyethylene, and it also adds a new type of VCI vapor phase rust inhibitor. When packaging metal workpieces, the rust-proof bag film layer will automatically evaporate VCI vapor phase rust prevention gas, which will gasify in a closed space and condense on all metal surfaces, including hard-to-reach surfaces such as holes, holes, and crevices, forming a vapor phase protective layer, thereby preventing metal workpieces from rusting.


II. Application range of rust-proof bags


Rust-proof bags are suitable for the storage, transportation, and packaging of various industrial products, such as auto parts, machine tool accessories, bearings, pipes, mechanical parts, etc. At the same time, rust-proof bags can also be used together with other packaging materials, such as cartons, wooden boxes, and barrels.

III. Advantages of rust-proof bags


1. Long-term storage of metal products

The rust and corrosion resistance of rust-proof bags is very strong, and it can store metal products for a long time, keeping their original performance.

2. Convenient to use

Rust-proof bags are simple to use, you just need to put the metal products directly into the bag and seal it, and it can protect the metal products well.

3. Safety and environmental protection

Compared with other rust-proof materials, the materials of rust-proof bags are safer and more environmentally friendly.

4. Economic and practical

Using rust-proof bags can reduce equipment damage and maintenance costs during production and transportation, and reduce economic losses for enterprises.

5. Good visibility

The rust-proof bag has high transparency, and you can easily observe the status and quantity of the items in the bag. In addition, rust-proof bags can often be customized in size according to customer requirements.

6. Cost reduction and efficiency increase

The workpieces protected by rust-proof can be unpacked and used immediately, eliminating the need for oiling, degreasing and cleaning. Improve work efficiency, save costs. VCI-2000 rust-proof bags are recommended.

IV. Storage requirements for rust-proof bags


1. In order to guarantee the rust prevention performance of the rust-proof bag, avoid exposing the rust-proof film in the open environment, whether indoors or outdoors.

2. The unused or remaining rust-proof packaging materials should be

stored tightly after use.


In conclusion, rust-proof bags are a simple, easy-to-use, environmentally friendly and practical rust-proof material, which can greatly extend the service life of metal products and reduce enterprise losses. With the increasing awareness of environmental protection and the continuous innovation of the packaging industry, rust-proof bags have become the ideal packaging choice for various products.
