Introduction of Aluminum-Plastic Composite Heavy-Duty Bags

Aluminum-plastic composite bags, also known as pure aluminum center seal gusset bags, aluminum foil gusset heavy-duty bags, and M-type gusset masterbatch heavy-duty bags. The products are developed to combine aluminum and plastic films through one or multiple dry-lamination processes.

The Structure of Aluminum-Plastic Composite Heavy-Duty Bags

Surface Layer

Keep Performance: The surface layer is designed to provide strength, puncture resistance, and anti-slip properties.

Safe and Efficient: The integrity of the layer ensures that the bag can withstand rough handling, and various environments and prevent slippage.

Temperature Resistance: Within a specific process, maintaining its protective properties in diverse climatic conditions.

 

Barrier Layer

Moisture Resistance: The Barrier layer makes the bag moisture resistant and keeps the contents dry and safe from water damage.

Light Protection:  It shields the contents from light exposure, which can be detrimental to certain sensitive materials.

Oxygen Barrier: An excellent oxygen barrier, which is crucial for preserving the freshness and quality of the products, extending the shelf life of the products.

 

Heat Seal Layer

Adaptability: Different packaging processes suit versatile materials.

Permeability Resistance: It prevents the permeation of external contaminants, ensuring the contents remain uncontaminated.

Superior Heat Seal Performance: It ensures a strong and durable seal, preventing leaks and maintaining the integrity of the packaging.

 

Common Material Structures

PET/AL/PA/PE

Functionality: PET enhances strength and rigidity, aluminum is a barrier against light and oxygen, polyamide provides durability and puncture resistance, and polyethylene ensures flexibility and sealability.

Applications: Products need high barrier and excellent packaging impression properties, such as food items, pharmaceuticals, and chemicals.

 

PE/AL/PA/PE

Functionality: PE offers flexibility and sealability, while aluminum and polyamide ensure barrier properties and strength.

Applications: Suitable for containing flexibility and seal performance, such as packaging for liquids, powders, and industrial products.

 

PET/AL/PE

Functionality: The main role of PET is rigidity and printability. Aluminum offers barrier properties, and PE ensures sealability and flexibility.

Applications: Typically used for packaging products with moderate barrier and good visual, such as snacks, pet food, and personal care items.

 

The features of Aluminum-Plastic Composite Heavy-Duty Bags

Moisture-proof: Aluminum-plastic composite bags prevent internal products from moisture, keeping them dry and free.

Tear Resistance: High resistance to film punctures and tears, reducing damage from loss of film retention force.

Customizable Features: Resealable zippers, spouts, and handles can be customed to enhance safety and convenience.

 

Conclusion

Each layer of the aluminum-plastic composite heavy-duty bag contributes to the overall functionality and performance of the bag, making it excellent durable, moisture-resistant, and load protection.
