Foil barrier packaging is the newest innovation in industrial packaging. combine aluminum and plastic film to create a high-performance barrier. This is ideal for sensitive and integrity content. Compared with paper and plastic, aluminum ensures moisture-proof, leak-proof, and block any lighting from penetrating through. These bags allow for beautifully printed exteriors to appeal to customers. They also allow to add one-way degassing and vacuuming which can provide more performance.

 

Our aluminum plastic bag is made from multiple layers of materials, primarily aluminum foil and plastic films. The aluminum layer acts as an excellent barrier to light, moisture, and gases, while the plastic layer provides flexibility, strength, and ease of use. Due to the high barrier, it is always applied for packaging products that require a high level of protection, including food, pharmaceuticals, electronics, and other sensitive materials.

 

What are they applied to?

Aluminum-plastic composite barrier bags are used in various industries because of their versatile and protective qualities.

 

Food Packaging: With aluminum and plastic, the pack is used for snacks, dried foods, powdered products, and other perishable items.

Pharmaceuticals: Medicines and health supplements that require protection from moisture, air, and light, which are isolated from external factors.

Electronics: The high barrier pack’s moisture-resistant and static-free properties benefit sensitive electronic components such as semiconductors, circuit boards, and memory chips.

Chemicals: Many chemicals will degrade or lose efficacy when exposed to light or humidity. So multi-layer bags are crucial for materials during transportation and storage.

What is the structure of foil barrier packaging bags?

The structure of foil barrier packaging is typically made up of multiple layers of different materials. The general structure includes:

Out layer (Plastic Film): The outermost layer is usually a durable plastic film, such as PET (polyester) or OPP (oriented polypropylene), which provides strength, flexibility, and the ability to be printed with logos, designs, and product information.

 

Multi-layer (Aluminum Foil): The aluminum foil acts as the principal barrier to light, moisture, oxygen, and smells. This layer is thin but highly effective at protecting the product’s integrity inside.

 

Inner layer (Plastic Film): The innermost layer is often made of food-safe plastic, such as PE (polyethylene) or CPP (cast polypropylene), which adds a moisture barrier and protects the product from contamination during filling.

 

This multi-layer construction ensures that the packaging is not only long-lasting, but also lightweight, cost-effective, and capable of safeguarding delicate products from external elements that could lead to spoilage or damage.

What are the product specifications?

Now, I will introduce some common aluminum plastic composite barrier bag specifications.

 

Thickness: The thickness of this barrier packaging typically ranges from 50 to 200 microns, depending on the protection products required. The bags are thicker, the protection is stronger. But you need to spend more money to buy them. A thicker bag provides strength but may be less flexible.

 

At the same as other packaging, aluminum foil bags also have many types.

Gusseted type: Gusseted bags are designed with expandable sides that allow them to stand upright when filled, maximizing the volume and capacity of the bag. So it is ideal for packaging bulk goods, powders, and liquids, as it enhances stability and accessibility during storage and transportation. When filled fully, the bags exhibit great stability because of its gusset.

 

K-Seal bottom: As a specific type of seal, it provides structural integrity and allows the bag to stand up when filled. The K-seal bottom enhances the bag’s volume appearance, making it more visually appealing while also providing a sturdy base that can withstand stacking during shipping and storage.

 

One-way degassing valve: the one-way degassing valve is a critical component for packaging products that release gases, such as coffee beans or fermented materials. The valve allows gases to escape from the bag while preventing external air from entering, thus protecting the contents from oxidation and contamination.

 

Conclusion

In today‘s competitive market, maintaining the integrity of your products during storage and transportation is essential. Aluminum foil barrier bags offer unparalleled protection, combining the superior barrier properties of aluminum with the strength and flexibility of plastic films. It is especially ideal for sensitive pharmaceuticals, chemicals, and electronics.

 

No matter what you are packaging, our bag will offer an airtight, leak-proof, and tamper-resistant solution. Furthermore, this bag can be customized with one-way degassing valves, gusseted sides, or K-seal bottoms.
