The VCI Metal Barrier Bags are made using metal barrier technology that is used to prevent moisture penetration for articles which travel in open condition and require high moisture barrier. These are also used where the sea transit time is long or components are placed without individual packaging and require very high moisture protection. Hi Tech International manufactures VCI Metal Barrier Bags. Hi Tech International is an ISO 9001:2000 certified company. The VCI Metal Barrier Bags is totally impermeable to humidity. After the machine or components are packed, the chemicals from the paper surface evaporate and form a VCI atmosphere inside the packaging and prevent corrosion due to the humidity.
