Aluminum foil for cigarette packaging foil
Cigarette Packaging Foil is a specialized type of aluminum foil used to package cigarettes, offering a combination of protection and aesthetic appeal.
Material Composition
Aluminum
The primary component, known for being lightweight, durable, and non-toxic. Its reflective properties make it ideal for enhancing product appearance.
Lamination
Often laminated with paper or other materials, adding strength and improving its ability to seal in freshness.
Purpose and Function
Moisture Barrier
Cigarette packaging foil provides an excellent barrier against moisture, preventing the tobacco from drying out.
Oxygen Barrier
Protects against oxidation, which can affect the taste and quality of the tobacco over time.
Aesthetic Appeal
The foil gives a premium, shiny look that enhances the brand image and attractiveness of the packaging.
Light Protection
Keeps the contents safe from light exposure, which can degrade the tobacco.
Common Types
Inner Foil Wrap
A thin layer directly wrapped around the cigarettes inside the carton or box.
Outer Packaging Foil
Often used on the exterior for decorative and protective purposes, combined with other materials.
specifications
The specifications of Cigarette Packaging Foil can vary based on the manufacturer's requirements, but there are standard features that ensure the foil's performance in protecting the cigarettes.
Material: 99% pure aluminum is typically used for cigarette packaging foil to ensure quality and durability.
Thickness: 0.006 mm to 0.007 mm (6 to 7 microns) for inner cigarette foil.
Thicker foils (7 microns) are often preferred for better tear resistance, while thinner foils may be used in low-cost packaging.
Width: 200 mm to 1500 mm, depending on the packaging machine and manufacturer.
Weight: Typically around 19-20 g/m² for standard packaging foils.
Temper: Soft (O) Temper
Provides flexibility and is easy to wrap around products without cracking or tearing.
Surface Treatment: One side of the foil is usually polished for a shiny appearance (bright side), while the other remains matte. The shiny side is often placed facing out for aesthetic purposes.
Coating and Laminates: Foil is often laminated with paper (typically 20-25 gsm), or plastic to provide added strength and ensure a snug fit around the cigarettes. Heat-sealable lacquer or wax may be applied for sealing purposes.
Embossing: Some foils are embossed with specific designs, such as company logos or decorative patterns, to enhance brand visibility and appeal.
Barrier Properties:
Water Vapor Transmission Rate (WVTR): Less than 0.01 g/m²/24 hr, ensuring the foil's ability to prevent moisture from reaching the cigarettes.
Oxygen Transmission Rate (OTR): Near zero, ensuring no oxygen penetration, which helps maintain the freshness of the tobacco.
Adhesion and Bond Strength: For laminated foils, the adhesive must provide excellent bonding between the aluminum and paper layers to ensure durability during handling and storage.
Heat Sealable: Foils may be coated with heat-sealable layers to allow for easy and effective sealing during the packaging process.
Color: Silver and Golden are the most common color for cigarette foils, but they can also be printed with brand logos or custom designs for marketing purposes.
Common Standards:
Alloy Grades: Typically 8011 or 1235 aluminum alloys are used, which provide excellent mechanical properties for packaging applications.
Standards Compliance: Foils should meet relevant international standards like ISO for food-grade packaging to ensure safety and hygiene.
