umers,tape samples The formaldehyde content of 3 mg / kg, there is contact with packing tape before washing the formaldehyde content of the sample was 30 mg / kg, after cleaning the formaldehyde content of 10 mg / kg in some cities prohibit packing tape tied dish According to public information, the country has Some cities prohibit the direct use of packing tape tied vegetable .2011 March, under the Harbin Municipal Agricultural Commission issued "on the prohibition of direct use packing tape bundling sales of vegetables notice" that the binder contains a variety of chemical constituents remaining in the vegetables difficult to clean, easy to cause harm to humans. sub conductive fabric packing tape, which is made of conductive fabric packing tape, which is based on characteristics of conductive fabric on the increase of the "glue" feature, an important characteristic of the word can refer to --- conductive fabric strips. on general industry hope of "glue" is a conductive adhesive, it is a "nickel" component, in order to play the magnetic shielding effect. But there does not need to and just plain conductive adhesive acrylic adhesive or the hot melt adhesive, conductive cloth goal is to have enough to have good adhesion properties of conductive fabric packing tape:.. ◎ good electrical conductivity and shielding effect ◎ good anti-friction properties, anti-friction frequency of up to 5,000,000 times (NF35B050 , ASTM D 4966) ◎ good metal adhesion and electrical wizard Z ◎ good workability (NF35B050):.. soft, cut no edges, anti-fingerprint dirt, antioxidant treatment primarily conductive fabric packing tape. : conductive fabric is covered by polyester fiber exterior metal copper and nickel and other metal surface constituted by woven fiber layer is a high conductivity copper, corrosion-resistant surface is the oxidation of nickel metal copper and nickel.
