Steps To Custom Flexible Packaging

Film Extrusion

We melt premium resins into precise foundation films tailored for extreme puncture resistance, high barrier, or permanent ESD protection.

Ultra-HD Printing

Your brand comes to life. Our high-speed 10-color rotogravure presses deliver ultra-HD resolution and a 98% color reproduction rate for maximum shelf impact.

Solvent-Free Lamination

Using an advanced solvent-free coating system, we securely bond multiple functional layers, followed by temperature-controlled curing for ultimate strength and zero odor.

Slitting & Pouch Making

Laminated rolls are slit and fed into automated pouch-making lines. We integrate custom add-ons (zippers, valves) and apply precision sealing for leak-proof durability.

Lab Testing & QA

Before shipping, every batch undergoes rigorous physical and chemical testing in our in-house lab (tensile, seal integrity, ESD) to ensure IATF 16949-level compliance.

Packaging Features & Custom Options

Focus on usability, structure, and visual customization, we engineer packaging that works perfectly for your end-users. From retail-ready hang holes to resealable zippers, every functional component is fully customizable to elevate your product’s usability and shelf appeal.

Engineered Film Structures for Barrier Performance

Designed to meet your product’s exact barrier needs — moisture (WVTR), oxygen (OTR), light, and puncture resistance.

Aluminum Foil / AL

The ultimate barrier material. It offers maximum protection against moisture, oxygen, and UV light, ensuring maximum shelf life. Engineered to withstand extreme conditions, it maintains structural integrity even during high-temperature retort sterilization (up to 135°C).

Key Features:

  • Maximum oxygen & moisture barrier
  • Excellent UV and light protection
  • Retort-grade capable (withstands 121℃–135℃)
  • Ideal for chemical, coffee, and retort food packaging

Metalized PET / VMPET

A cost-effective alternative to pure aluminum. It provides excellent barrier properties with a premium metallic finish, widely used in retail and electronics. This versatile film perfectly balances visual appeal with reliable performance, helping your brand stand out on the shelf.

Key Features:

  • High moisture & oxygen barrier

  • Premium metallic visual appeal

  • High tensile strength and flexibility

  • Ideal for snack foods, cosmetics, and standard electronics

Electrostatic Discharge / ESD (Modified PO)

Engineered for sensitive electronics. Utilizing physical grid modification instead of chemical coatings to ensure permanent protection and zero dust. Trusted by global tech giants, it completely eliminates the risk of short circuits caused by chemical shedding.

Key Features:

  • Permanent anti-static protection (≤ 10⁴ Ω)

  • Zero Non-Volatile Residue (NVR) / Dust-free

  • Passes extreme 72-hour vibration tests

  • IATF 16949 certified for automotive electronics

Polyamide / NY (Nylon)

Unmatched toughness. Nylon provides exceptional puncture resistance and flexibility, making it perfect for heavy-duty industrial and vacuum packaging. With our advanced lamination process, it securely protects sharp or heavy components under the most demanding transport conditions.

Key Features:

  • Extreme puncture resistance (Up to 8-12N)

  • Excellent vacuum and forming capabilities

  • High tolerance to low temperatures (Freezer grade)

  • Ideal for heavy industrial parts and sharp objects

Polyethylene Terephthalate / PET

The standard outer layer for flexible packaging. It provides excellent heat resistance, dimensional stability, and an ultra-smooth surface for high-definition printing. It serves as the perfect canvas for our ultra-HD rotogravure presses, bringing your most complex artwork to life.

Key Features:

  • Supports ultra-HD 10-color rotogravure printing

  • Excellent heat resistance for stable sealing

  • High clarity and dimensional stability

  • Available in high-gloss, matte, and soft-touch finishes

Mono-Material / PE/PO/CPP

Designed for a circular economy. These mono-material structures offer necessary barrier protection while being 100% ready for recycling streams. They are fully backed by GRS certifications, allowing your brand to meet strict global ESG requirements without compromising quality.

Key Features:

  • 100% Recyclable mono-material structure

  • GRS & RCS certified traceability

  • Comparable barrier performance to standard laminates

  • Helps brands meet global ESG requirements

Bio-based / PLA & PBAT

The future of eco-friendly packaging. Enhanced by Eonsen’s proprietary modified formula, these materials balance compostability with long-term shelf stability. This breakthrough successfully resolves the industry pain point of premature degradation, extending reliable physical protection up to 3 years.

Key Features:

  • Fully compostable and biodegradable

  • Proprietary formula extends physical stability up to 3 years

  • Excellent seal strength and printability

  • Reduces environmental impact and fossil fuel reliance

Sustainable Flexible Packaging Solutions

Engineered with innovative mono-material structures (PE/PO/CPP). They deliver the same extreme barrier protection and ultra-HD printability as traditional laminated pouches, but are fully ready for the recycling stream.

Crafted from premium bio-based materials (PLA, PBAT). Featuring our proprietary modified formulas, these pouches guarantee up to 3 years of physical stability on the shelf before naturally breaking down.

Achieve your global ESG goals without compromising on quality. EONSEN engineers fully certified eco-friendly packaging that perfectly balances high-barrier product protection with environmental responsibility.
