ESD anti-static moisture-proof foil bag, also known as aluminum foil shield vacuum bag, aluminum foil bag, vacuum bag, moisture-proof bags. Appearance: silver white, matt and light two kinds. Features: anti-static, anti-electromagnetic interference, moisture-proof three functions, Faraday electric cage construction, shielding barrier average of up to 60db, powerful electrostatic protection, inner layer of pure metal aluminum, resistivity of less than 0.1Ω, four structural composite ability, sealing strong, has a good waterproof, blocking oxygen, light, puncture resistance. Material Structure: anti-static layer (PET) / aluminum foil layer (shield moisture barrier) / PET / antistatic layer (PP or PE) Performance: electrical properties and physical properties to meet international standards ASTTMD257, EIA541, MIL-B-81705 and other conventional Thickness: 4mils 5.5mils 7mils surface resistivity: 8-11 Ω power of the bag 10 style: flat pocket,, envelope, envelopes, self-adhesive, Siamese-style, three-dimensional and other self-styled (dense bag / zipper bag) body bags pattern can be printed according to customer requirements. Usage: Suitable for electronic moisture-proof packaging requirements: PC boards, IC integrated circuits, optical drives, hard drives, as well as chemicals and biological intermediate vacuum packaging. bopp-- BOPP biaxially oriented polypropylene film, also known as biaxially oriented polypropylene film, the English abbreviation code bopp, which is characterized by stretching molecular orientation, mechanical strength, flexural strength, gas density, moisture Barrier better than ordinary plastic film. Compared unit area and cellophane, priced at less than cellophane. Since this film is excellent in transparency, in India after exceptionally bright and beautiful color reproduction is an important base plastic composite flexible packaging.
