| Stand Up Aluminum Foil Envelopes Bisque 215x260mm #E Vinyl Puncture
Resistant for Grocery | | | | Speciallity | | A kind of aluminum rolled into sheets of hot stamping material, the
effect of stamping and silver foil stamping similar effects, it is
also called the false. Because of its soft texture and good
ductility, it has silver and white luster. If the rolled sheet is
rolled on the offset paper with sodium silicate and other
materials, it can also be printed. But the aluminum foil itself is
easy to oxidize and the color is darkened, and the friction, touch
and so on will turn color, so it is not suitable for the hot
stamping of the books and periodicals, such as the long - preserved
books and periodicals. | | | | Brief Introduction | Aluminum Foil Envelopes
Packaging bag made of pure aluminum foil and plastic film. Aluminum
foil surface can be printed graphics, with sunscreen, high
temperature resistance, moisture and moisture, anti-static
function. Widely used in food vacuum packaging, electronic products
anti-static packaging, chemical raw materials packaging, drug
packaging, etc..
Product principle:
Aluminum Foil Envelopes with metal foil and inherent
characteristics, qualitative light luster, strong reflection
ability, after the plastic film composites as thermal insulation
packaging, good barrier property, impervious to gases and water
vapor, strong adaptability to temperature, high temperature or low
temperature shape stabilized, shading, retention of aroma are
excellent.
Structure:
Three layers of Aluminum Foil Envelopes PET/AL/CPE, four layers of
foil bag PET/AL/NY/CPE
Production method:
Composite equipment will compond the aluminum foil and plastic film
to generate a composite membrane, then the bag making equipment
will sealing sides, after that, the cutting equipment will cut the
sealing film according to customer’s size to finished the bags.
Production process:
Composite technology, thermal fusion technology, cutting
technology, bag making process
characteristic:
1 barrier air performance is strong, anti oxidation, waterproof and
moistureproof
2 puncture resistant, tear resistant and storng performance.
3 high temperature resistance, low temperature resistance, oil
resistance, and good performance.
4 anti-static, anti electromagnetic interference (the production
process of composite anti-static materials can be anti-static)
Technical parameter:
The surface resistance value of 10 8~11 Times Square, the thickness
of 8~18 wire, heat sealing temperature of 150 C + 10
Use:
Food vacuum packaging, pharmaceutical packaging, electronic
products, anti-static packaging, etc. | | | | Data Sheet | | Optional Materials: | PVC | | Melting Point : | 205℃ | | Working Temperature : | -15°C~+80°C | | Material Density : | 1.34g/cm³ | | Common Size : | 215x260mm #E | | Sample Color : | Bisque | | Basic Material : | Vinyl | | Protruding Characteristics : | Puncture Resistant | | Typical Application Industry : | Grocery | | Shape Style : | Stand Up | | 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. |
