Waterproof Packing

Waterproof Packing refers to the use of waterproof materials or processes to package goods in order to prevent damage from moisture, rain, or humid environments. Common materials include waterproof paper, plastic film, waterproof bags, sealed containers, etc. It is typically used for moisture-sensitive goods (such as textiles, paper, electronics, food) during ocean shipping or open-air storage. Precautions: select the appropriate waterproof grade based on the characteristics of the goods; the packaging should be sealed intact and free from damage; note the difference from Moisture-proof Packing, which focuses on preventing moisture vapor penetration, while Waterproof Packing emphasizes preventing liquid water intrusion. In addition, waterproof packing is not necessarily completely watertight and may only be splash-proof. Unlike 'Sealed Packing,' which emphasizes complete isolation from air and moisture, Waterproof Packing focuses more on protection against liquid water. In foreign trade contracts, specific standards for waterproof packing should be clearly stated, such as using 0.1mm thick PE bags, to avoid disputes.
