Cos'è il foglio di alluminio per contenitori?

Il foglio di alluminio per contenitori si riferisce al foglio di alluminio appositamente progettato e prodotto per contenitori per imballaggi alimentari. È un tipo di foglio di alluminio generalmente più spesso e più resistente del foglio di alluminio domestico standard. La pellicola per contenitori è comunemente utilizzata nel settore dei servizi di ristorazione per confezionare una varietà di prodotti alimentari, come i pasti da asporto, spuntini pronti, and other perishable goods. Container aluminum foil provides a barrier against moisture, leggero, oxygen and other external factors that can degrade food quality.

Why choose aluminum foil as a container?

A common use of aluminum foil is as a packaging material. As a food container material, aluminum foil has many advantages that cannot be replaced by other materials.

Strong barrier properties: Container aluminum foil has excellent barrier capabilities against moisture, leggero, oxygen and other pollutants. This helps maintain the freshness, flavor and nutritional value of the food stored in the container.

Conduttività termica: Aluminum foil has excellent thermal conductivity and can heat and cool food evenly. This makes it suitable for the storage and transportation of hot and cold food.

Leggero: Aluminum foil material is lightweight and easy to handle and transport. This is particularly beneficial for packaging and shipping large quantities of food, such as in the food service industry.

Flexibility: Aluminum foil is highly flexible and can be easily molded into different shapes and sizes to suit various types of food products.

Riciclabilità: Aluminum foil is recyclable and recyclable, meaning it can be reused and recycled multiple times without losing its quality. This makes it an environmentally friendly choice compared to other packaging materials.

Cost-effective and efficient: Aluminum foil is relatively cheap compared to other packaging materials such as plastic or glass. It provides a cost-effective solution for food packaging, especially disposable or single-use containers.

Strong corrosion resistance: Aluminum foil is corrosion-resistant, ensuring that food stored in aluminum foil containers is safe and free from contamination.

Container aluminum foil product specification

Product specifications for container aluminum foil can vary depending on factors such as intended use, manufacturing standards, and customer requirements. Tuttavia, here are some common specifications that may be included for container aluminum foil:

Container aluminum foil alloy: The aluminum alloy used, such as AA3003 or AA8011, which determines the material’s mechanical properties, formabilità, and suitability for food packaging.

Container aluminum foil temper: The temper designation, such as H22 or H24, indicating the material’s hardness and strength characteristics after manufacturing processes like cold rolling and annealing.

Aluminum foil container thickness: The thickness of the aluminum foil, typically measured in microns (micron) or mils (1 mil = 25.4 micron). Common thicknesses for container aluminum foil range from around 10 A 50 micron, depending on the specific application.

Width and Length: The dimensions of the aluminum foil roll or sheet, specifying the width and length of the material, which may vary depending on customer requirements and production capabilities.

Surface Finish: The surface finish of the aluminum foil, which may be specified as plain (uncoated) or coated with a protective or decorative layer to enhance performance or appearance.

Coating or Lamination: If applicable, specifications for any coatings, laminations, or treatments applied to the aluminum foil surface to improve barrier properties, resistenza al calore, or other characteristics.

Tolleranza: Tolerances for dimensions such as thickness, larghezza, e lunghezza, indicating acceptable variations from the specified values during manufacturing.

Imballaggio: Details regarding the packaging of the aluminum foil rolls or sheets, including the method of packaging, packaging materials used, and any special handling instructions.

Conformità: Compliance with relevant industry standards and regulations, such as FDA regulations in the United States or European Union directives for food contact materials.

Physical Properties: Additional physical properties such as tensile strength, allungamento, and surface quality may also be included in the specifications, depending on customer requirements and the intended application of the aluminum foil.

These specifications help ensure that the container aluminum foil meets the required quality, performance, and safety standards for its intended use in food packaging applications. Manufacturers and suppliers typically provide detailed product specifications to customers to facilitate proper selection and usage of the aluminum foil products.

3003 alloy aluminum foil container

Container foil is typically made from aluminum alloy grades with specific properties suitable for food packaging applications. The most commonly used alloy for container aluminum foil is AA3003.

Vantaggi di 3003 lega di fogli di alluminio

Buona formabilità: Foglio di alluminio 3003 alloy has excellent formability and can be easily molded into various shapes and sizes required for food containers.

Strength and Durability: Foglio di alluminio 3003 provides sufficient strength and durability to withstand food handling, transportation and storage.

Conduttività termica: AA3003 foil alloy has good thermal conductivity, ensuring even heating and cooling of food contents.

Resistenza alla corrosione: Lega di alluminio 3003 has corrosion resistance, ensuring that food is not contaminated during storage and transportation.

Riciclabilità: AA3003 alloy is recyclable, making it an environmentally friendly choice for food packaging applications.

Foglio in lega di alluminio 3003 is the most commonly used aluminum foil alloy for containers, but other alloy grades, ad esempio 8011 foglio di alluminio, may also be used depending on specific requirements such as thickness, strength and formability.

Is aluminum foil safe for containers?

Aluminum foil for containers is generally considered safe for food packaging, thanks to the material properties of aluminum foil

Proprietà barriera: Aluminum foil blocks moisture, ossigeno, light and other contaminants, helping to maintain the freshness, flavor and nutritional quality of food.

Food Grade Materials: Aluminum foil used for food packaging is typically manufactured to meet strict food safety standards.

Non tossico: Aluminum foil itself is non-toxic and inert, meaning it will not react with food or release harmful substances when in contact with food under normal conditions.

Avoid high temperatures: While aluminum foil is safe to use in the oven or wrap hot food, it is best to avoid excessively high temperatures, such as those reached when baking or grilling, as this may cause the foil to degrade and may transfer small amounts of the foil . Food contains aluminum.
