Foil has a glossy side and a matte side. A bright side is created when the aluminum is rolled in one pass. It is difficult to produce a roll with a gap sufficient for the thickness of the foil, so for the latter process, two sheets are rolled at the same time, doubling the gauge thickness at the entrance of the roll. When the foil is separated later, its inner surface becomes dull, while its outer surface shines. This difference in finishing has led to the belief that favoring the sides when cooking is effective. While many believe that different properties block heat from entering when the glossy finish is packaged outwards, and keep heat in when the glossy finish faces inwards, the actual difference is imperceptible without instrumentation. The increase in reflectivity reduces the absorption and emission of radiation, and industrial foils may only have a non-stick coating on one side.
Aluminum foil has unique dead space properties that make it ideal for packaging and repackaging many different products and product shapes, while minimizing the need for sealants. Because it is very malleable, it can easily deform without losing the integrity of its barrier layer, making it ideal for use in combination with other flexible substrates to produce very thin laminates for a variety of markets, which saves resources again.
Industrial aluminum foil has many properties, so it can be widely used in packaging aluminum foil for food, beverage, cigarette, medicine, household aluminum foil, etc. In addition, it can be used as electronic capacitor material, building material, thermal insulation material, printing material, sign or label material, etc. In all these applications, the properties of aluminum foil can be greatly exhibited as a packaging material. Lichen Aluminum Foil can produce all kinds of high-quality aluminum foil such as 8011 aluminum foil and aluminum foil 3003, and has won high praise from customers.
With the economic transformation and structural adjustment, green consumption continues to upgrade, and people's lifestyles continue to change, commercial aluminum foil packaging has ushered in new opportunities, and its market share has continued to grow, becoming a segment of the aluminum industry that maintains growth. At present, aluminum foil packaging has been widely used in the fields of food, beverage, medicine and daily chemicals to ensure the freshness and safety of food, prolong the shelf life, reduce food waste, reduce plastic packaging and protect the ecological environment. Aluminum foil packaging can promote the sustainability of packaging products and promote green consumption, but it also faces many disputes and material competition. The current market environment and its changes have put forward new challenges and new requirements for aluminum foil materials and the aluminum foil industry. The aluminum foil industry is adapting to the new situation, accelerating product improvement and growth mode transformation, and taking the road of sustainable development.
In this context, we will discuss the current situation and prospects of aluminum foil packaging applications, the challenges and opportunities of the aluminum foil industry, and discuss the sustainable development direction of the industrial aluminum foil industry chain and future innovation trends, so as to promote green aluminum foil packaging and expand the internal circulation of aluminum foil.
