Extra Large Size Plastic Compounds Bag Multi Layer Structure For Sensitive Materials

Ultra-High Barrier Laminate Extra Large Size Pouch (PET/AL/PA/PE)

The Ultimate Protection for Demanding Products

Our premium multi-layer laminate pouch, constructed from a sophisticated combination of Polyethylene Terephthalate (PET), Aluminum (AL), Polyamide (Nylon, PA), and Polyethylene (PE), represents the pinnacle of packaging technology. This structure is engineered to provide an almost impenetrable shield against external elements, making it the definitive solution for products that are highly sensitive to moisture, oxygen, light, and aroma loss.

Key Barrier Properties: Unmatched Protection

This 4-layer material is designed to deliver the highest grade of protection available in flexible packaging.

• Ultimate Oxygen Barrier: The central Aluminum (AL) layer acts as a complete, absolute barrier to oxygen and other gases. Virtually eliminates oxidation, ensuring long-term stability for products prone to spoilage, rancidity, or degradation.
• Absolute Moisture Vapor Barrier: The Aluminum layer provides a 100% barrier to moisture vapor. Guarantees product dryness and integrity in the most humid environments.
• Superior Aroma and Flavor Lock: The combination of the AL and PET layers creates a total barrier to volatile organic compounds. Preserves the authentic taste and potent aroma of the contents.
• Complete Light Barrier: The opaque Aluminum layer blocks 100% of visible and ultraviolet light. Protects light-sensitive contents from UV degradation.
• Exceptional Strength and Puncture Resistance: The Polyamide (PA) layer provides outstanding mechanical strength, toughness, and puncture resistance. Enhances durability and integrity.

Plastic Compounds Bag – Extra Large Size, PET/AL/PA/PE Multi-Layer

Engineered for Unmatched Durability

Designed to withstand the toughest industrial environments, this extra-large bag features a PET/AL/PA/PE multi-layer structure that delivers exceptional durability for bulk storage of sensitive materials.

Durability Advantages

1. Puncture Resistance

   • PA (Nylon) reinforcement layer provides 40% higher puncture resistance compared to standard bags, protecting contents from sharp edges or rough handling during transport.
   • Maintains integrity under heavy loads and dynamic stress (ASTM D3787).

2. Tensile Strength & Tear Resistance

   • PET outer layer offers high tensile strength (≥120 MPa) and abrasion resistance, preventing tears or ruptures from mechanical impact.
   • PA layer enhances flexibility while resisting crack propagation under cyclic loading (ASTM D882).

3. Environmental Resilience

   • AL layer protects against UV degradation, ensuring long-term stability in outdoor or high-light exposure conditions.
   • PE sealing layer maintains flexibility in extreme temperatures (-40°C to 80°C), preventing brittleness or warping (ASTM D1922).

4. Impact Absorption

   • Multi-layer design absorbs shocks during drop tests, minimizing damage to contents.
   • Withstands vibrations and stacked loads in palletized storage.

Why Durability Matters

• Reduced waste: Fewer replacements due to tears or leaks.
• Lower costs: Minimizes downtime and logistics disruptions.
• Reliable performance: Ensures product safety in harsh conditions.

Ideal for industries requiring rugged, long-lasting packaging – pharmaceuticals, chemicals, food additives, and electronics.
