Three Side Seal Aluminum Foil Envelopes Brown 5"X10" #00 PVC Security for Office
Speciallity
Also as a foil, in Hongkong called the foil is a kind of metal aluminum flat manufacturing tools, mainly used for kitchen cooking, food containers, or used to make some simple cleaning materials. Thousands of tons of aluminum foil are used in all parts of the world to protect and package food, cosmetics and chemicals. Most of the aluminum foil is bright on the other side and the other side is dumb. Both sides of the aluminum foil for food can be wrapped up on both sides of the food, which is usually suggested to be wrapped in bright bread to improve the heat transfer effect.
Brief Introduction
Aluminum Foil Envelopes
Aluminum Foil Envelopes performs well in the packaging of industrial products, hardware, circuit board, electronic parts and component and other static sensitive products for the requirements being vacuum, anti-static, moisture proof, keeping out of light.
The aluminum foil bag is sliver, opaque and glossy.
Aluminum Foil Envelopes’s surface resistance value: 105Ω - 1011Ω.
With great barrier property, heat sealing, corrosion resistance, shading, non-toxic and tasteless features, Aluminum Foil Envelopes protects the content from moisture, static and electromagnetic interference.
The regular design of aluminum foil bags include flat bag, seal-adhesive bag, zip lock bag, three-dimensional bag and organ bag.
The customized thickness, size, design and printing are available.

Materials introduction
The color is yellowish, translucent and lustrous. Transparency is better than polyethylene, polypropylene, poor polystyrene, with the auxiliary dosage is different, divided into soft and hard PVC, soft products soft and tough, feel sticky, hardness of hard goods is higher than low density polyethylene, and lower than polypropylene, in the inflection place will appear whitening phenomenon. Stable; not easy to be acid and alkali corrosion; heat tolerance.
PVC has the advantages of flame retardant (flame retardant value above 40), high chemical resistance (concentrated hydrochloric acid, sulfuric acid concentration of 90%, nitric acid concentration of 60% and sodium hydroxide concentration of 20%), mechanical strength and good electrical insulation advantages.
Polyvinyl chloride has poor stability to light and heat. The softening point is 80, and it begins to decompose at 130. In the absence of heating stabilizer, PVC began to decompose at 100 degrees Celsius, and decomposed faster than 130 degrees celsius. When heated, the hydrogen chloride gas is released, and hydrogen chloride is toxic gas, which makes the color change from white to pale yellow to red to brown to black. Ultraviolet rays and oxygen in the sun will cause the decomposition of polyvinyl chloride, which makes the flexibility of polyvinyl chloride decrease and finally become brittle. From here, it is not difficult to understand why some PVC plastic will become yellow and brittle for a long time.
