It is self-evident how important the packaging is for a product. Compared with the decorative effect of the surface, the storage and protection function of the bag is more important. But in fact, many people tend to ignore this point, a large extent, this is because they do not understand the bag itself.
First of all, we know about the knowledge of the aluminum foil bag. Aluminum foil bag is divided into two kinds of aluminum bag and pure aluminum bag. The aluminum plating bag is a high temperature vacuum state, and the high purity metal aluminum is evenly coated on the plastic film. Pure aluminum bag is made of pure metal aluminum, combined with plastic, it can improve the barrier property, sealing, fragrance protection, shielding and other functions of plastic. |

| 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. |

Advantage
1. has good mechanical properties, impact strength is 3~5 times of other films, good folding resistance.
2. oil resistant, fat resistant, acid tolerant, dilute alkali, resistant to most solvents.
3. with high and low temperature performance, can be used for a long time at 120 degrees Celsius temperature range, short-term use of resistant to high temperature of 150 DEG C, -70 resistant to low temperature, and high and low temperature effects on the mechanical properties is very small.
The permeability of 4. gas and water vapor is low, and it has excellent performances of gas resistance, water, oil and odor.
5. high transparency, can block ultraviolet light, good gloss.
6. non-toxic, tasteless, sanitary, safe, and can be used directly for food packaging. |
