High Barrier Aluminum PE Carton PE Sheet For Inner Packing Lining

Product Overview

Product Introduction

Aluminum/PE/Carton/PE sheet, also known as Aluminum-Polyethylene-Carton-Polyethylene laminated sheet, is a high-performance four-layer composite material engineered for superior barrier protection and structural integrity. This innovative laminated structure combines the unique properties of each individual layer to create a versatile packaging solution that excels in both functionality and sustainability.

The four-layer configuration follows a precise sandwich design:

1. Outer Aluminum Layer: Provides exceptional barrier against oxygen, moisture, light, and contaminants

2. First PE (Polyethylene) Layer: Acts as an adhesive bonding layer and offers additional moisture resistance

3. Carton (Paperboard) Core Layer: Delivers structural rigidity, printability, and eco-friendly characteristics

4. Inner PE Layer: Ensures safe food contact, heat sealability, and chemical resistance

This multi-layer construction is produced using advanced extrusion lamination or dry lamination techniques, ensuring consistent bonding and optimal performance across the entire sheet surface.

Note: Custom specifications available upon request to meet specific application requirements.

Manufacturing Process Of Aluminum/PE/Carton/PE sheet

1. Material PreparationSelect food-grade aluminum foil, coated carton board, and low-melt-index PE resin; perform surface treatment (corona treatment) to improve bonding fastness between layers.

2. Extrusion Lamination / Dry Lamination

1. Extrusion lamination: Molten PE resin is extruded as a thin film to bond aluminum foil and carton board.

2. Dry lamination: Use adhesive to compound aluminum foil with PE film, then laminate with carton board and inner PE layer.

3. Cooling & SettingThe composite web passes through a cooling roller system to stabilize layer bonding and eliminate internal stress.

4. Slitting & WindingCut the large-width sheet into target sizes according to customer requirements, then wind into rolls or cut into flat sheets.

5. Pre-delivery InspectionConduct appearance, thickness, barrier property and bonding strength tests before packaging and delivery.

Applications Of Aluminum/PE/Carton/PE sheet

Aluminum/PE/Carton/PE sheet is a versatile material with wide-ranging applications across multiple industries, primarily in packaging solutions requiring both barrier protection and structural integrity:

1. Food & Beverage Industry

• Liquid Food Packaging: Aseptic cartons for milk, juice, plant-based beverages, and soup

• Dry Food Packaging: Premium packaging for coffee, tea, powdered milk, and nutritional supplements

• Convenience Food: Ready-to-eat meal trays, instant noodle bowls, and frozen food containers

• Pet Food: High-barrier packaging for dry and semi-moist pet food products

2. Pharmaceutical & Healthcare

• Medical device packaging requiring sterile barrier protection

• Pharmaceutical sachets for tablets, capsules, and powdered medications

• Nutraceutical packaging for vitamins and dietary supplements

3. Industrial & Specialty Applications

• Chemical packaging for solvents, adhesives, and lubricants requiring multi-barrier protection

• Agricultural chemical packaging (pesticides, fertilizers) with enhanced safety features

• Electronics packaging for moisture-sensitive components

4. Consumer Goods

• Cosmetic and personal care product packaging (creams, lotions, powders)

• Household product packaging for detergents, fabric softeners, and cleaning agents

Advantages of Aluminum/PE/Carton/PE sheet

Aluminum/PE/Carton/PE sheet offers a unique combination of benefits that distinguish it from traditional single-material or simpler laminated alternatives:

1. Superior Barrier Performance

• Absolute Oxygen Barrier: Aluminum layer provides near-100% impermeability to oxygen, preventing oxidation and extending shelf life by 2-5 times compared to plastic-only packaging

• Excellent Moisture Resistance: Dual PE layers and aluminum foil create a robust defense against moisture ingress, critical for preserving product quality

• Light & UV Protection: Aluminum layer blocks harmful UV rays and visible light, protecting light-sensitive products from degradation

2. Structural & Functional Excellence

• Optimal Rigidity: Carton core delivers superior structural support for handling, stacking, and transportation without deformation

• Secure Heat Sealability: Inner PE layer enables strong, consistent heat sealing for tamper-evident and leak-proof packaging

• Versatile Printability: Carton layer provides an excellent surface for high-quality printing, supporting brand differentiation and product information communication

3. Sustainability & Cost Efficiency

• Material Efficiency: Laminated structure uses minimal material while maximizing performance, reducing overall environmental footprint

• Recyclability: Compatible with modern material recovery systems for separation of aluminum, paper, and plastic components

• Cost-Effective: Lower total cost of ownership compared to glass or metal packaging, with reduced transportation costs due to lighter weight

4. Safety & Regulatory Compliance

• Food-Safe Design: Inner PE layer meets global food contact standards (FDA, EU, etc.) for direct food contact applications

• Chemical Resistance: PE layers provide protection against most common chemicals, ensuring product purity

• Tamper-Evident Features: Heat-sealable properties enable secure closure systems to protect against contamination and counterfeiting
