Introduction of Anti-rust three-dimensional bag products
Product definition and structure
The Anti-rust three-dimensional bag is a customized packaging container made from polyethylene (PE) or polypropylene (PP) using a three-dimensional hot-press molding process. The inner layer is coated with vapor phase corrosion inhibitor (VCI). Its three-dimensional structure perfectly fits the contours of irregular metal parts, providing 360° rust protection.
The core structure of Anti-rust three-dimensional bag:
Outer layer: high strength PE/PP film, puncture resistant and tear resistant (thickness 0.1-0.3mm optional)
Middle layer: VCI corrosion inhibitor coating (5-15g active ingredients per square meter)
Inner layer: electrostatic adsorption layer to ensure uniform distribution of rust prevention molecules
Technical advantages of Anti-rust three-dimensional bags
Precise protection
The three-dimensional bag type can be customized according to the 3D scanning data of the work piece to avoid the crease gap of the traditional flat bag (such as gears, crankshaft and other complex parts)
The penetration rate of rust prevention molecules is 99.7% (ASTM B117 salt spray test ≥ 2000 hours)
Increase efficiency and reduce cost
The rust prevention oil coating process is eliminated, and the packaging efficiency is increased by 60%
Reusable design (up to 3 cycles) reduces the cost per unit by 40%
Environmental compliance
Through REACH/SDS certification, VCI is an organic amine compound with a degradation cycle of less than 180 days
Typical application scenarios of Anti-rust three-dimensional bags
Industry applicable product protection cycle: 3 years for automobile manufacturing gearbox assembly and turbine blade; 5 years for energy equipment valve group, pipeline flange; 2 years for precision electronics and 5G base station metal cavity
How to use the Anti-rust three-dimensional bag
Pretreatment: the work piece should be cleaned until the surface residual oil is less than 5mg/m²
Encapsulation: it is recommended to seal with hot air welding gun (temperature 120±10℃)
Storage: stack height ≤ 2 meters, avoid direct ultraviolet light
