Lele Peak milk packaging

Tetra Brik Aseptic Edge is an innovative aseptic packaging solution developed by Tetra Pak specifically for liquid foods, excelling in applications such as milk, juice, and plant-based beverages. Below is a detailed breakdown of its features in terms of materials, manufacturing processes, structural design, and sustainability technologies:

I. Material Composition and Composite Technology

1. Multi-Layer Composite Materials
   The Tetra Brik Aseptic Edge packaging utilizes a six-layer composite structure, including:

   • Paperboard: Provides structural support, with 75% sourced from FSC-certified forests to ensure sustainable forestry practices.

   • Aluminum Foil: Acts as an oxygen and UV light barrier, preventing oxidation and spoilage of contents.

   • Polyethylene (PE) Layers: The inner layer ensures leak-proof sealing, while the outer layer enhances durability.

   • Plant-Based Polymers: Select caps (e.g., LightWing™30) incorporate sugarcane-derived polyethylene, reducing reliance on fossil-fuel-based plastics.

2. Eco-Friendly Material Innovations
   Tetra Pak employs Direct Injection Molding Compression (DIMC) to minimize plastic usage. By 2023, sales of plant-based packaging materials increased by 20% year-on-year.

II. Manufacturing Processes and Aseptic Technology

1. Aseptic Filling System
   Combines Ultra-High Temperature (UHT) sterilization technology, heating milk to 130°C–150°C for seconds before rapid cooling. This process eliminates microbes while preserving bioactive nutrients (e.g., immunoglobulins, lactoferrin). Products are filled in sterile environments, enabling months-long shelf stability at ambient temperatures.

2. Differentiated Sterilization Methods

   • Pasteurization (75°C): Used for Bright Dairy’s "Youbai" series, retaining active enzymes like lactoperoxidase (1,500 U/L).

   • Ceramic Membrane Filtration (1.4-micron pores): Applied in Bright Dairy’s "Zhiyou" series for low-temperature bacterial removal, preserving vitamins and minerals.

3. Production Flexibility
   Compatible with Tetra Pak® A3/Flex filling machines (e.g., model 0600v), achieving a maximum output of 8,000 packs/hour and rapid capacity switching (e.g., 500ml to 1.4L).

III. Structural Design and Functional Enhancements

1. Ergonomic Design

   • Sleek, Tall Profile: Enhances shelf visibility and optimizes storage efficiency compared to traditional Tetra Brik bricks.

   • Angled Top & Wide Spout (30mm): Minimizes drips during pouring, catering to children and users with smaller hands.

2. Cap Innovations

   • AngelCap™30: One-step twist-off design with tamper-evident features and pre-cut membranes for easy opening and resealing.

   • Dual-Seal Technology: Maintains airtightness even after secondary closure, extending freshness (e.g., Bright Dairy’s fresh milk).

IV. Sustainability Initiatives

1. Low-Carbon Production & Recycling

   • Carbon Neutrality Goals: Aim to reduce greenhouse gas emissions from raw materials by 50% by 2030 (vs. 2019 baseline), achieving 22% reduction by 2023.

   • Recycling Systems: Partnering with Ai Hui Shou to establish low-value recyclable sorting centers. Packaging is recycled into products like tote bags and notebooks. China’s recycling rate reached 41% in 2013.

2. Logistics Optimization
   Lightweight designs and improved stacking efficiency reduce transport emissions. For example, 1.4L large-format packaging cuts per-unit transportation frequency.

V. Market Applications & Industry Recognition

1. Case Studies

   • Bright Dairy: Launched 1.4L Tetra Brik Aseptic Edge fresh milk with a "one-step cap" design, positioning it as a premium product with bioactive nutrient levels (e.g., lactoferrin at 50mg/L) exceeding industry standards.

   • South Korea’s Maeil Dairy: Achieved significant sales growth by replacing traditional gable-top packaging with 900ml Tetra Brik Aseptic Edge for refrigerated white milk.

2. Awards
   Won Germany’s "Packaging of the Year" and "WorldStar" Design Award, praised for its angled design, spill-resistant features, and eco-performance.

Conclusion

The Tetra Brik Aseptic Edge redefines liquid food packaging standards through multi-layer composites, UHT sterilization, ergonomic design, and full-chain sustainability practices. By balancing functionality (e.g., bioactive nutrient retention) and environmental responsibility (e.g., plant-based materials), it serves as a core solution for dairy companies pursuing premiumization and green transformation.
