Face film bags for mask how important, this is self-evident.
Compared with the fancy decoration on the surface of the role, bags storage, protection function is more important.
But, in fact, a lot of people point, ignores this, to a large extent, this is they don't know the bag itself.
First of all, we know the knowledge about the aluminum foil bag.
Aluminum foil bag into aluminium bag and two kinds of pure aluminium bag.
Aluminium bag is under the high temperature vacuum, high purity aluminum evenly on the plastic film.
Pure aluminium bag tablet is pure metal aluminum, and plastic compound, can improve the barrier property of plastic, sealing, incense, shielding, and other functions.
Aluminum foil bag and aluminized bag can through the following several ways to distinguish discrimination: 1, watch: brightness than aluminum plating bright because of the aluminum foil, aluminum foil so reflective sex less than aluminum plating film, aluminium bag can reflect figure, except extinction film aluminum plating.
Extinction film plating aluminum and aluminum foil very approximate appearance.
Can the bag mouth, through the light bag, aluminum foil bag inside not pervious to light, pervious to light is aluminized bag.
2, feel is: aluminum foil bags of grip and crisp thick hard, heavy, feel of aluminized bag than aluminum foil bag is light and soft.
3, folding: aluminum foil bag easy to fold one dead plait mark, aluminized bag not folding into a dead plait, and will rebound soon.
4, twist twist: aluminum foil bags of coalescence is not easy to rebound after twist twist, aluminum layer will appear rupture.
Aluminium bag soon after twist twist NiuJieChu will play out, aluminum layer there would be no obvious cracks.
5, fire: fire won't burn, aluminum foil with aluminum layer will rollback, the aluminum foil packing will leave after burning gray aluminum slag.
Aluminum plating film can appear different plastic film when fire burning, no residual aluminum slag.
Function of the mask packing at first, the use of aluminum foil bag on the mask packaging mainly for functional requirements.
The back of the mask usually has the words & other;
Avoid direct sunlight and placed under the interesting and ventilated dry place & throughout;
, this also reflect in order to keep the activity and effect of facial mask, facial mask packaging must meet the following basic functions, 1.
3 moisture resistance;
In general, the aluminum foil bag can basically meet the above requirements.
But in specific on the one hand, pure aluminium bag than aluminized bag has more advantages, such as pure aluminium bag has completely avoid light, aluminized bag only certain shading sex;
On the barrier property and cooling, pure aluminium bag also have obvious advantages.
In addition, aluminum foil bag with a variety of features: 1.
Cut off the air performance is strong, anti-oxidation, waterproof, moistureproof.
Strong mechanical properties, high blast resistance, resistance to puncture tear resistance is strong.
High temperature resistant,
, good low temperature resistance,
- - - - - -
, oil resistant, good performance.
Avirulent insipidity, accord with standard of health food, pharmaceutical packaging.
Heat sealing performance is good, softness, high separation performance is good.
No wonder, began to appear on the market recently aluminized bag to pure aluminium bag structure change.
Mask the white-hot competition, has spread to the packaging industry.
High-end driven by the structural transformation of high-end mask has become a trend nowadays, in addition to the excellent performance reflects on the aluminum foil bag, the most intuitive is the embodiment of the texture.
Relative aluminum plating, good metal texture, pure aluminum is silvery white, have the burnish properties;
Aluminum metal features soft, can be customized according to the requirements of different composite material and the thickness of the product, meet the thick texture of the pursuit of high-end products, make high-end mask is reflected from the packaging.
Functional requirements, the basis of face film bag from the beginning to now performance synchronization with the texture of high-end requirements, is the change of aluminized bag to pure aluminum bag, belongs to a new era under the mask of the packaging industry structure change requirements.
