About 8011 Coated Aluminum Foil 12 Micron: Core Characteristics

Là gì 8011 Nhôm?

• 8011 giấy nhôm is an alloy in the 8000-series family that is highly formable, has excellent sealing compatibility, and offers good barrier properties when used as foil.
• Typical composition emphasizes aluminum with small additions of trace elements that improve bakeability, compatibility with coatings, and corrosion resistance in food-contact environments.
• Common temper for packaging foil is O (mềm mại, ủ) or lightly worked to preserve formability.

Tại sao 12 Micron Thickness?

• 12 microns is a widely used thickness for flexible packaging foil; it provides:
• Sufficient barrier and puncture resistance for many food and consumer goods.
• High adaptability to high-speed converting, in ấn, and lamination lines.
• Excellent sealability when paired with compatible coatings and heat-sealing structures.
• Tolerances are typically tight, often ±0.5 μm, to ensure consistent performance across lots and batches.

Coating Options: What Makes It “Coated”

• Single-sided coatings: Often used for heat sealability and compatibility with the secondary packaging layers.
• Double-sided coatings: Employed when a specific adhesion, barrier, or aroma/ moisture control is required, especially in laminated structures.
• Common coating chemistries:
• Polyetylen (PE/LDPE): Offers heat-sealability and barrier enhancements.
• Polypropylen (CPP) and Polyethylene terephthalate (THÚ CƯNG): Provide mechanical stability and improved printing or lamination performance.
• Ethylene-vinyl alcohol (EVOH) and other barrier polymers: Used in high-barrier laminates for extended shelf life.
• Biodegradable coatings: PLA-based or bio-based coatings for sustainability-driven packaging.
• Coating adhesion and compatibility with printing inks, adhesives, and lamination layers are critical for long-term performance.
