1235 Aluminium Foil 7 Micron

Aluminum Foil alloy 1235 has a wide range of applications, from yogurt covered foil, medical packaging foil, household foil, food container foil, automotive insulation film to tape aluminum foil.

What are the Characteristics of 1235 Aluminum Foil ?

1, mechanical ability
Generally, aluminum foil is light in weight, good in ductility, thin in thickness, and small in mass per unit area. However, the strength is low, it is easy to tear, it is easy to break when folded, and holes are generated, so it is usually not used alone for packaging products. In many cases, it can be mixed with other plastic films and papers to overcome its shortcomings.
2, high barrier performance
Aluminum foil alloy 1235 is highly barrier to water, water vapor, light and aroma and is not affected by the environment and temperature. Therefore, it is commonly used in snack packaging, cigarette packaging, moisture-proof packaging, etc., to prevent moisture absorption, oxidation and volatilization of food in the package. It is especially suitable for high temperature retort sterilization packaging of food.
3, corrosion resistance
The surface of the aluminum foil 1235 naturally forms an oxide film, and the formation of the oxide film can further prevent the continuation of oxidation. Therefore, when the contents of the package have high acidity or alkalinity, the surface is usually coated with a protective coating or coated with PE to improve its corrosion resistance.
4, heat resistance, low temperature resistance
The high temperature of aluminum foil is stable at low temperature, and does not shrink at -73~371 °C without deformation, good thermal conductivity, and thermal conductivity up to 55%. Therefore, it can be used for high temperature cooking or other thermal processing, as well as for cold packaging.
5, shading
Aluminum foil alloy 1235 has good light-shielding properties, reflectivity up to 95%, and a silver-white metallic luster. The surface printing decoration can show good packaging and decorative effects, so aluminum foil is also a high-grade packaging material.

Aluminum foil has become one of the most widely used packaging materials in the global packaging industry. Its barrier properties, versatility, light weight and recyclability make it an attractive choice for a variety of food, pharmaceutical and industrial packaging applications. One thickness of aluminum foil in particular has seen spectacular growth in recent years – 7 micron aluminum foil.

Factory made Aluminum Foil 7 Micron Foil offers key advantages that make it a popular choice for flexible packaging. At just 0.007mm thick, it provides excellent barrier protection while maintaining flexibility. This allows it to be used in a wide range of applications where thinner foils were not previously feasible. The rise of new filling and packaging technologies has also enabled the use of 7-micron foil on high-speed production lines. As a result, it has become the thickness of choice for many food and consumer goods companies looking to offer innovative packaging formats.

The development of flexible packaging

The rapid expansion of the global flexible packaging industry is driving the demand for wholesale Alu Foil 7 Micron Alloy 8011/1235. Flexible packaging such as sachets, bags, wraps and foil lids offer many advantages over rigid containers for food brands. They allow for custom design, graphics and packaging marketing to help products stand out on crowded store shelves. The flexible format is also lightweight, which reduces shipping and storage costs. Most importantly, they provide an excellent barrier against moisture, oxygen, grease and bacteria, thereby extending the shelf life of packaged products.

Flexible packaging is widely used in food sectors such as snacks, fresh foods and frozen foods. Flexible packaging formats are growing in popularity as consumers increasingly seek portable, single-serve and on-the-go packaging options. 

The boom in flexible packaging has spurred huge demand for thin aluminum foil, as its barrier properties make it an ideal material for many multi-layer flexible packaging structures. The thin 7 micron gauge provides the flexible features required for high-speed switching operation while still providing the oxygen and moisture protection of aluminum. As a result, 7-micron foil finds application in food categories, from snacks and confectionery to fresh and frozen produce. It is usually laminated or extruded coated films such as polyethylene or polyester to produce composite foil packaging structures.

With the rapid rise of flexible packaging and the emergence of new application areas, 7 micron aluminum foil is poised to play a more important role, providing a superior barrier with optimal thinness, flexibility and ease of processing. Its unique combination of attributes makes it the thickness of choice for innovative packaging formats in global consumer markets.
