Is aluminum foil affected if it remains in the warehouse for a year or two?

Aluminum foil is a material that can be seen everywhere in daily life and is indispensable, especially in the packaging industry. It plays an important role. With its advantages of lightness, good thermal conductivity, corrosion resistance, and easy forming, it is widely used in various fields and has become one of the indispensable raw materials in the packaging industry.

What are aluminum foil used for?

First of all, one of the most common uses of aluminum foil is food packaging. Due to its excellent barrier properties, it can effectively block the influence of air, moisture, light, etc. on food and extend the shelf life of food. Therefore, aluminum foil is often used in food packaging paper, beverage bags, candy packaging, etc. In addition, aluminum foil is also used for pharmaceutical packaging, which can well protect drugs from the influence of the external environment. Aluminum foil in the kitchen is also a common tool, used to keep the fresh taste of food during baking and grilling, or as a sealing material for food storage.

In addition to the packaging field, aluminum foil is also widely used in the construction and industrial fields. For example, in construction, aluminum foil is used as insulation and moisture-proof materials, which can effectively reflect solar heat and reduce indoor temperature. In the electronic and electrical industry, aluminum foil is used as a shielding material for cables to prevent electromagnetic interference.

What alloys are there for aluminum foil?

There are various types of aluminum foil alloys, and different alloys are suitable for different application scenarios. Common aluminum foil alloys include 1235, 3003, 8011, 8079, etc. 1235 alloy has high corrosion resistance and is often used in food and pharmaceutical packaging; 3003 alloy is often used in Food Container Aluminum Foil due to its excellent strength and corrosion resistance; 8011 aluminum foil is widely used, Household Aluminum Foil, Aluminum Container Foil, Flexible packaging Aluminum Foil, and food packaging foil all have 8011 aluminum foil. 8079 alloy is usually used for flexible packaging materials.

What specification are there for aluminum foil?

In terms of thickness, the thickness of aluminum foil usually ranges from 0.006mm to 0.2mm, and different thicknesses are suitable for different purposes. Thinner aluminum foil is suitable for use as lightweight packaging materials, while thicker aluminum foil is used for industrial purposes that require more support. In terms of width, the width of aluminum foil also has a variety of specifications, usually ranging from 50mm to 1600mm, and the specific specifications are selected according to actual needs.

In general, aluminum foil is widely used in packaging, construction, electronics and other industries with its excellent performance, and meets diverse needs through different alloys, thicknesses and specifications.

Is aluminum foil affected if it remains in the warehouse for a year or two?

Generally speaking, aluminum foil can be used normally after being stored in a warehouse for one to two years. However, the storage conditions are high.several factors may affect its quality:

Humidity: The storage environment should be kept dry. If the warehouse environment is humid or the humidity fluctuates greatly during the storage time, the aluminum foil will oxidize and corrode. It will affect normal use. The humidity is best controlled between 40% and 60%. Especially when the aluminum foil comes into contact with acidic or alkaline items.

Temperature: The suitable temperature range for storing aluminum foil is usually between 10°C and 35°C. This temperature range can help maintain the integrity of the aluminum foil and prevent it from becoming fragile or difficult to use due to excessively high or low temperatures. However, drastic temperature changes may cause the aluminum foil to expand and contract, so the appropriate temperature is also important.

Storage away from light: Although aluminum foil is less sensitive to light, long-term exposure to strong light may affect its gloss.

Dust and contaminants: The warehouse needs to be a closed one, and try not to contact dust, dirt or other contaminants, which will affect the cleanliness of the aluminum foil and make it unsuitable for food packaging.

For aluminum foil buyers, it is recommended that aluminum foil should not be stored for too long. Purchase in small quantities and purchase more often to achieve the freshness of the aluminum foil. In this way, the final product of the aluminum foil is fresh.
