We have small packs for individual boxes and hanging packs for whole containers. Call or message us on Zalo and we will send you a price.
The container leaves the factory in the heat, but out at sea the nights turn cold very quickly. Moisture inside meets the cold walls, condenses, and drips right onto the goods. At the port the buyer may open it to spotted shoe boxes, yellowed fabric and tarnished components, a shipment that has lost value and is sometimes sent back. Desiccant packs put in when you pack the cartons catch the moisture before it turns into water.
Silica gel is a porous bead of silicon dioxide, full of tiny pores that hold moisture. At 90% humidity it absorbs 35 to 40% of its own weight. The beads are inert, so they do not corrode your goods or give off any odor, and the pouch keeps them inside so no fibers fall onto the cargo. A 1g pack fits in a shoe box and a 500g pack hangs straight in the container, and some sizes can be printed with your logo, each with its own minimum order.
This is only a starting suggestion, and our staff will confirm the exact size for your cargo.
The table lists the shared specs of the silica gel packs we sell. Check it against your boxes, cartons or container.
01
The figure is a share of the pack's own weight. A 500g pack absorbs about 175 to 200g of water and a 5g pack about 1.75 to 2g. A 1g pack in a watch box or small parts box holds only about 0.35 to 0.4g, so the bigger the box, the heavier the pack you need (shoe boxes usually take a 5g pack).
02
35 to 40% was measured at 25°C and 90% humidity. Inside a real container, temperature and humidity move with the route and between day and night, so the actual amount can differ. Treat it as a reference and tell our staff which route the container takes and for how many days, and we will work out the number of packs for you.
03
For containers, the product page suggests about 4 packs of 500g for a 20ft and 8 for a 40ft on trips of up to 30 days, hung against the container wall. Four such packs absorb roughly 700 to 800g of water. For small boxes and cartons, pick a pack between 1g and 100g by carton size, and send us the carton dimensions so we can work it out with you.
These figures are reference values under test conditions, and our staff will confirm the size and dose against your actual cargo and route.
