Aluminum Foil & Aluminum-Plastic Film

Precision Inkjet Marking System for Al-Plastic Film | Anti-static & High-adhesion Marking Solution

Aluminum foil and aluminum-plastic composite substrates tend to cause ink bleeding and print peeling during inline coding due to static electricity accumulation and low surface energy features. Lanyin develops proprietary targeted technologies as below:

 

  • Anti-static Ion Surface Treatment System: Eliminates surface static charges completely to prevent ink feathering during high-speed continuous coding.
  • Nano-level High-adhesion Ink: Forms molecular bonding with aluminum layers, ensuring printed marks remain intact even under high-temperature boiling & sterilization.
  • Dynamic Tension Compensation Technology: Perfectly fits high-speed production of laminated foil. This solution delivers high-precision printing for power battery packaging, food stand-up zipper pouches and medical isolation films, permanently fixing the long-existing problem of poor marking durability on composite flexible packaging.

Solutions:

LION TEC customized inkjet coding solution is specially developed for aluminum foil and aluminum-plastic composite packaging production lines. The integrated system combines anti-static ion elimination equipment and dynamic tension compensation modules, realizing stable inline high-speed coding on continuously running flexible foil rolls. It effectively solves core industry defects including ink bleeding caused by static adsorption and print peeling from low-surface-energy composite materials, adapting to both large-volume full-automatic roll-film production and small-batch finished pouch static marking.

Application Markets:

The marking system covers diversified flexible packaging manufacturing sectors. Typical application fields include lithium power battery aluminum-plastic casing packaging, food stand-up zipper bags, pharmaceutical blister foil packaging, medical isolation membrane, daily chemical sachet packaging, vacuum aluminum foil wrapping and high-temperature retort pouch production. It widely serves new energy battery factories, food processing enterprises, pharmaceutical packaging manufacturers and medical consumable producers.

Printable Substrates:

Compatible with multiple composite substrates: single-layer aluminum foil, multi-layer laminated aluminum-plastic film, retort-grade composite foil, pharmaceutical blister aluminum foil, matte and glossy flexible aluminum composite membrane, as well as low-surface-energy coated plastic-aluminum compound materials. Formulated ink and printing parameters are optimized for static-prone flexible foil features to avoid ink spread, shrinkage or detachment without extra complicated surface pre-coating.

Printing Content:

It supports flexible variable and fixed information printing on foil surfaces, including production batch numbers, manufacturing dates, expiry codes, lot IDs, factory trace codes and specification parameters. Besides standard text and numeric data, the equipment realizes high-precision printing of 1D barcodes, traceable QR codes, anti-counterfeit encrypted codes and customized brand graphic logos. All variable printing data can be imported from multi-source databases for real-time editing and batch variable-data marking.

Ink Features:

  • Strong Adhesion: Nano-formulated ink achieves molecular bonding with aluminum layer, firmly attaching to low-surface-energy aluminum-plastic surfaces without falling off after high-temperature cooking, retort sterilization and long-term extrusion friction.
  • High Definition & Fine Printing: Delivers ultra-clear tiny character and fine pattern printing, suitable for compact small-area marking on miniature pharmaceutical blister and micro battery packaging.
  • Scratch & Wear Resistance: Printed marks withstand repeated folding, extrusion and transportation abrasion to retain permanent legibility on flexible deformed packaging.
  • Temperature & Humidity Resistance: Marks keep intact under high-temperature boiling, cold storage and humid warehouse environments without fading or ink blurring.
  • Fast Drying Performance: Instant drying after ejection to eliminate ink smudge during high-speed continuous roll-film conveying.
  • Diversified Ink Options: Available with food-grade ink, high-temperature resistant retort ink, anti-UV pigment ink and solvent-free eco-friendly ink to satisfy different food, medical and new-energy packaging standards.

Importance of Component Marking:

  • Product Specification Identification

    Aluminum-plastic pouches share highly similar outer appearances while differing greatly in raw material grade and usage standard; directly printed batch and specification information enables fast error-free sorting during incoming inspection and finished goods inventory management.

  • Guiding Customer Choice

    Clear printed production information and compliance marks convey product quality standard to purchasers, supporting customers to make reliable procurement judgments for food and medical packaging supplies.

  • Full Lifecycle Traceability

    Unique coded markings realize full supply chain traceability covering raw composite film production, pouch forming, filling processing and terminal circulation, supporting precise quality control and rapid product recall when quality problems occur.

  • Brand Reputation Protection

    Durable permanent printing prevents counterfeit inferior composite packaging from entering market, effectively protecting manufacturer’s intellectual property and brand market credibility.

  • Anti-Counterfeiting Security

    Custom encrypted QR anti-counterfeit imprints allow rapid online authenticity verification, safeguarding both brand benefits and end-user consumption safety.

  • Market Expansion & Sales Growth

    Stable long-lasting marking acts as reliable quality certification, lifting client trust and purchase willingness to boost continuous sales growth and market share expansion.
