What are the storage methods for rust proof paper?

10/25/2024

What are the storage methods for rust proof paper? Today, the editor will talk to you about three common and convenient methods for storing rust proof paper.

1. Store in a cool and dry place, with sealed packaging to avoid direct sunlight and contact with flammable and explosive objects;

2. The shelf life of general rust proof paper is within one to one and a half years, and it is recommended to use it within the shelf life for better results;

3. Do not come into contact with acidic or alkaline substances to prevent oxidation and rusting, which may affect the effectiveness of use;
The main function of rust proof paper is vapor phase rust prevention. A certain amount of vapor phase corrosion inhibitor is coated on the surface of the rust proof paper, which can be used for steel or multi metal applications. The vapor phase corrosion inhibitor has a certain vapor pressure. During use, the vapor phase corrosion inhibitor evaporates and adsorbs onto the metal surface with a film thickness of one to two molecules, forming a passive film that can effectively block the corrosion of the metal by corrosive atmospheres such as water vapor and oxygen, thus effectively preventing rust.

Metal packaging materials play an important role in modern packaging materials. Let’s talk about the disadvantages and advantages of metal packaging.

(1) Metal packaging materials have excellent barrier properties and comprehensive protective properties, with extremely low (almost zero) transmittance to gas, water, and water vapor. They have good fragrance retention and are completely opaque, effectively avoiding the harmful effects of ultraviolet radiation; Its air resistance, moisture resistance, light shielding, and fragrance retention far exceed other types of packaging materials such as plastic and paper. Therefore, metal packaging can provide excellent protective performance for the contents, which is beneficial for maintaining the quality of goods for a long time.

(2) Metal packaging materials with good mechanical properties, processability, and high strength have good ductility and high strength. They can be processed by stamping, rolling, stretching, welding, etc., and can be made into thin-walled, high pressure resistant, and durable packaging containers. They can also be combined with other materials to form composite packaging materials with excellent comprehensive performance.

(3) Having a special metallic luster and good surface decoration, combined with exquisite decorative printing, can make the appearance of the product luxurious, beautiful and marketable, while also increasing the value of the product.

(4) Convenient and hygienic metal packaging containers and inner coatings generally meet the requirements of hygiene and safety. Products packaged with them are easy to carry and use (usually equipped with easy opening devices, such as pull rings for cans), and can adapt to different climatic conditions. And the waste has good disposability and can be recycled and reused.
