  After figuring out classifications, you should also learn some purchasing tips if you want to buy aluminium foil rolls. First, ask more than two aluminium foil suppliers about price and samples. Second, learn as more details in advance as possible, like lead time, quality control, after sales service, payment term etc. Third, learn something about currency ratio before putting an order, and choose the best time when the ratio is favorable for you. And if you can learn more about local financial knowledge which your supplier make as a base before giving you an offer, you would harvest more than you expect.

Features of excellent packaging aluminium foil

  Aluminium foil packaging and packing are more and more popular in industries like food process, pharmaceutics and cosmetics. Feature of excellent packaging aluminium foil are as below.

  First, the surface cleanliness of an aluminium foil packing should be high, and the surface should be free from oily dust, and the surface tension should be high. When using a simple method, that is, when testing with distilled water, it should be completely wetted, and the surface tension should be above 72 mN/m. If the oil is severe, the composite fastness will not be high, especially after high temperature cooking, delamination will occur.

  Second, the number of pinholes should be small. Originally, aluminium foil rolls should be the best barrier material, but if there is a pinhole, the barrier effect will be greatly reduced. Gas, moisture, and light will penetrate directly and quickly, and the contents will deteriorate quickly. In general, the thicker the aluminum foil, the less the number of pinholes.

  Third, the texture of the aluminum foil packaging should be soft, not easy to break when folded, and have good toughness. Purchased aluminum foil should be stored in a dry state, and should not be placed for too long, should be used as fresh as possible to prevent aluminum foil from absorbing moisture and deterioration.

Two types of aluminium foil packaging

  There are two types of aluminium foil packaging. One type is to wrap food or objects with aluminium foil jumbo roll (or made into aluminium foil trays or containers), the other with aluminium foil bags.

aluminium foil packaging

  Aluminum foil paper is usually used for food packaging (such as aluminum foil paper tray). It is used to grill food like bean sprouts and sweet potatoes at a barbecue to avoid burning. Sometimes used for decoration. Modern aluminum foil paper is made of aluminum and can also be used as an aluminum electrode for electrolysis. There are also hair stylists who use perm foil to perm for guests. Some people also use aluminum foil to absorb the oil in the soup. Aluminum foil is also widely used for the barrier layer, heat exchange, and as an electrical conductor. Typically, aluminum foil used in paper bag beverage packaging and food packaging is only 6.5 microns thick. This thin aluminum layer is water resistant, savory, anti-bacterial and anti-fouling.

  The other type of aluminium foil packaging, aluminum foil bags, are used as tin foil bags, pure aluminum bags, just called different methods. Aluminum foil bags are suitable for a wide range of applications. Aluminum foil bags have strong barrier properties, anti-oxidation, water resistance, moisture resistance, strong mechanical properties, high blast resistance and puncture resistance. The characteristics of strong tearing performance are favored by electronic products and food packaging industry, and the development momentum has been particularly rapid in recent years.

  Core features: 1, good moisture, light and air barrier

  2, good heat sealing, long shelf life, sealed tight.

  3, beautifully printed, clear pattern, attract attention.

  4, dust-free production environment, 100% ketone-free benzene ink production, perfect quality control system is the continuous quality assurance for your authority.

  With either type of aluminium foil packaging, the quality of aluminium foil is very important. Haomei supplies aluminium foil jumbo roll, aluminium foil for containers, household aluminium foil and aluminium foil for packaging of medicine, food, cosmetics etc. Welcome to send inquiries!

Why is aluminium foil paper sheet so popular

  The aluminum foil paper sheet is widely used in food, beverage, cigarette, medicine, photographic floor, household daily necessities, etc., usually used as its packaging material; electrolytic capacitor material; thermal insulation material for construction, vehicles, ships, houses, etc.; Silver lines, wallpapers, and various decorative labels for stationery and light industrial products. So why is aluminum foil so popular?

aluminium foil paper sheet

  Among the above various applications, the most effective performance of the aluminum foil sheet paper is as a packaging material. Aluminum foil is a soft metal film, which not only has the advantages of moisture-proof, air-tight, light-shielding, abrasion resistance, fragrance preservation, non-toxic and tasteless, but also because it has an elegant silver-white luster, it is easy to process beautiful patterns of various colors and The pattern is thus more popular with people. In particular, after the aluminum foil is combined with plastic and paper, the shielding property of the aluminum foil is integrated with the strength of the paper and the heat sealing property of the plastic, thereby further improving the shielding performance for water vapor, air, ultraviolet rays and bacteria which are necessary as packaging materials. , greatly expanded the application market of aluminum foil. Since the packaged article is sufficiently isolated from the outside light, moisture, gas, etc., the package is well protected. Especially for the packaging of retort foods, the use of this composite aluminum foil material can at least guarantee that the food does not deteriorate for more than one year.

  In recent years, aluminum foil paper has been quite prominent in architectural applications, and it has been attached to the surface of the thermal insulation material to make it more convenient, clean and especially beautiful. But the effect of different kinds of aluminum foil paper is very different, such as fireproof and ordinary is not a grade.

  In addition, aluminum foil sheet paper is light in weight, non-toxic and tasteless, and has the highest cost performance among similar products. Most importantly, aluminum foil is recyclable, which is an incidental feature that has nothing to do with the popularity of the industry, but indirectly contributes to environmental protection. Therefore, under the same conditions, we should give priority to the use of recyclable aluminum foil.
