In the food industry, the choice of packaging materials is crucial, which is directly related to the safety, freshness and quality of food. As a high-performance and multi-functional packaging material, aluminum foil for food packaging occupies an important position in the market by virtue of its unique advantages. Food packaging foil manufacturer have strict requirements in terms of alloy, temper, thickness, quality and package to offer this high quality packaging material.
Aluminum foil for food packaging is usually made of alloys such as 8011 and 8021, which have good ductility, corrosion resistance and processing performance. In terms of thickness, according to specific application scenarios and needs, the thickness of aluminum foil for food packaging is generally between 0.016mm and 0.1mm. For example, sealing aluminum foil film is commonly used with a thickness of 0.02mm to 0.05mm, which ensures good sealing and effective cost control.
Food packaging foil manufacturer have very high quality requirements and must meet food-grade standards. Specifically, the product should have a clean surface, no oil, no black threads and foreign matter inclusions, flat plate, good flexibility, and not easy to break when folded. In addition, the number of pinholes in the aluminum food packaging foil needs to be strictly controlled, and the pore size should not be greater than 20μm to ensure the barrier performance and sealing of the package. Meanwhile, the cleanliness of the food packaging aluminum foil is also one of the important indexes, and the surface tension should be more than 72Mn/m to ensure the composite firmness with other packaging materials.
Remarkable advantages of food packaging aluminium foil:
– Excellent barrier properties
Aluminum foil for food packaging has excellent barrier properties, which can effectively isolate air, moisture and light, thus prolonging the shelf life of food and maintaining its freshness and taste. This is especially important for foods that are easily oxidized and susceptible to moisture.
– Good high temperature resistance
Aluminum foil has excellent high-temperature resistance and can withstand extreme conditions such as high-temperature cooking without deformation or rupture, so it is widely used in food packaging that requires high-temperature processing, such as canned goods and high-temperature cooking bags.
– Environmentally friendly and healthy
Aluminum foil for food packaging is non-toxic and tasteless, in line with national health standards, and does not produce harmful substances in the process of use, which is harmless to human health. At the same time, aluminum foil is a recyclable material, which is conducive to the recycling of resources and environmental protection.
– Beautiful and generous
Aluminum foil packaging has a metallic texture and beautiful appearance, which can enhance the grade and attractiveness of products. Meanwhile, aluminum foil packaging is easy to print and process, and can be personalized according to customer needs.
To sum up, aluminum foil for food packaging plays an important role in the field of food packaging with its excellent barrier performance, good high temperature resistance, environmental protection and health, as well as beautiful and generous features. With consumers’ increasing demand for food safety and quality, the market demand for aluminum foil for food packaging will continue to grow. In the future, with the continuous progress of technology and process optimization, the performance of food packaging aluminum foil will be more excellent, providing safer and more efficient packaging solutions for the food industry.
