| 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. | |

| 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. | |
