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. | | Data Sheet | Optional Materials: | PVC | Melting Point : | 205℃ | Working Temperature : | -15°C~+80°C | Material Density : | 1.34g/cm³ | Common Size : | 5"X10" #00 | Sample Color : | Brown | Basic Material : | PVC | Protruding Characteristics : | Security | Typical Application Industry : | Office | Shape Style : | Three Side Seal | Classification: | Aluminum Foil Envelopes | | | 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. |
