Printed Aluminum Foil Film for Food Grade Packaging                                                        

Product Overview

Engineering the Functional Core

Alloy 8011-O is the definitive choice for flexible packaging. Refined with specific trace elements to enhance tensile strength and elongation, this alloy provides a robust yet flexible core for multi-layer lamination.

High-Performance Structural Integrity                                                                       

Unlike standard foils, 8011-O offers superior "dead-fold" characteristics, ensuring that once the package is formed and sealed, it maintains its shape and airtight integrity.

Manufacturing Process: Precision from Casting to Slitting

We employ a rigorous six-stage production cycle to guarantee zero-defect output:

1. Refining & Casting: High-purity 8011 aluminum ingots are melted and alloyed to precise specifications.

2. Cold Rolling: The alloy is rolled through multiple passes to reach ultra-thin gauges with a thickness tolerance of ±3%.

3. Surface Engineering: The foil undergoes degreasing and corona treatment to achieve Grade A Surface Wetting (38+ Dyne/cm).

4. HD Rotogravure Printing: Using heat-stable inks, we apply high-definition graphics with a Delta-E < 1.5 to ensure brand consistency.

5. Slitting & Infrared QC: Master rolls are slit to custom widths, while online infrared sensors monitor for pinholes and printing alignment.

Technical Specifications

High-Performance 8011 Alloy Multi-Layer Composites for Superior Protection

In the modern global supply chain, food safety and structural integrity are inseparable. By integrating the unique chemical properties of 8011-O aluminum alloy with advanced lamination technology, we have created an innovative packaging solution that excels in both functionality and sustainability.

Whether protecting sensitive powdered nutrients or high-fat snacks, our engineered foil sheets ensure a near-perfect barrier against environmental degradation, maintaining product excellence from the production area to the consumer's table.

Product Advantages

Absolute Barrier Performance: The 8011-O layer provides 100% protection against UV light, moisture, and oxygen, effectively stopping the oxidation of fats and oils in snacks.

Enhanced Structural Resilience: Our innovative Combination structure combines the stiffness of metal with the flexibility of polymer films, preventing package failure even under high-pressure nitrogen flushing.

Premium Visual Brand Identity: High surface energy ensures that 10-color printing remains vibrant and sharp, allowing for metallic effects and complex logos that drive shelf conversion.

Global Export Compliance: Fully certified by the Saudi Food and Drug Authority (SFDA) and FDA, ensuring your products meet the highest safety standards in the Middle East and beyond.

International Applications

Snack & Puffed Food: Vital for chips and extruded snacks that require nitrogen-flushed packaging to maintain crispness.

Premium Coffee & Tea: The high-barrier structure locks in aromatic oils and prevents the ingress of moisture that causes clumping.

Pharmaceutical Sachets: Meets strict medical guidelines for protecting powdered medications and granules from environmental degradation.

Confectionery & Dairy: Used for chocolate bars and high-end milk powders that require light-proof packaging and excellent seal integrity.

FAQ

Q1: Can this film run on high-speed VFFS machines?

A: Yes. We calibrate the Coefficient of Friction (COF) of the sealant layer (typically 0.2–0.3) to ensure the film glides smoothly through forming tubes at speeds over 100 bags per minute without jamming.

Q2: Does the matte finish affect the barrier properties?

A: Not at all. The matte finish is achieved on the outer BOPP layer, while the core 8011 aluminum foil continues to provide the same high-level OTR/WVTR barrier protection.

Q3: How do you prevent delamination in humid climates?

A: We use high-performance, solvent-free adhesives and achieve                                                             on the aluminum surface, creating a molecular bond that remains stable across extreme temperature and humidity fluctuations.

Q4: What is the typical lead time for a custom-printed project?

A: First-time orders take 20-25 days (including cylinder engraving), while repeat orders with existing designs are typically shipped within 15 days.
