Packaging and Transportation
The packaging should be able to withstand the impact, vibration, stacking and extrusion that may be encountered during transportation, while also it has to easy to load, unload and handle.
We use professional wafer box packaging. The wafer box is protected by a double layer bag, the inside is a PE bag that can be dust-proof, and the outside is a aluminum foil bag that can be isolated from the air. The two-layer bags are vacuum-packed.
We will choose carton models according to different sizes of products. And between the product and the carton filled with shock-proof EPE foam, play a comprehensive protection.
Finally choose air transport to reach the customer's hands. This allows customers in any country and region to receive the product in the fastest time.
We comply with the Material Safety Data Sheet (MSDS) rules to ensure that the products transported are free of harmful substances and will not cause environmental pollution and explosion and other possible hazards.
