Usage: moisture requirements applicable to electronic product packaging: PC boards, IC integrated circuits, optical drives, hard drives, as well as chemicals and biological intermediates vacuum packaging. Food issue has been broad interest in the problem of removing the food itself, the packaging has become another important issue. As food bags material is not the same, so he has the particularity itself is different. As personal food composition, its quality, the printing ink is also very important. Some exquisite designs printed bags, with a lot of ink, benzene substances containing it more if it exceeded the residual amount of words, for human consumption after it, it may cause chronic poisoning. Many companies blindly pursue excessive beautifully packaged, often ignored issue of food security.
