Product details
The pouch has a gusseted design, which means that the sides of the pouch can expand to create a flat bottom when filled, providing stability and allowing the pouch to stand upright. The pouch is also sealed using a square seal, which provides a secure closure to prevent any leakage or spillage of the contents inside.
This type of pouch is commonly used for packaging dry food products such as coffee, tea, snacks, and pet food. It is a popular choice for manufacturers and retailers who are looking for sustainable and cost-effective packaging solutions that offer protection and convenience to the consumers.
The barrier protection will be highly improved when adding both aluminum film and kraft paper layers?
When both kraft paper and aluminum film are used in a packaging bag, they work together to provide excellent barrier protection against moisture, oxygen, and light. The kraft paper provides a sturdy outer layer, while the aluminum film creates a barrier against external factors that can damage or contaminate the contents of the bag.
Kraft paper is a natural and sustainable material that is known for its strength and durability. It can withstand punctures and tears, making it a reliable choice for packaging bags. On the other hand, aluminum film is a flexible and lightweight material that can provide a high level of barrier protection against moisture, oxygen, and light.
By combining these two materials, the packaging bag can offer enhanced protection to the contents inside. The kraft paper provides a strong outer layer that can withstand external forces, while the aluminum film creates a barrier that prevents moisture and oxygen from entering the bag and damaging the contents.
Overall, using both kraft paper and aluminum film in a packaging bag can provide excellent barrier protection, making it a popular choice for packaging a wide range of products, including food, pharmaceuticals, and chemicals.

The flexible packaging barrier protection material function from low to high?
The barrier protection of flexible packaging can vary depending on the specific material or combination of materials used in the packaging. Generally speaking, the barrier protection of flexible packaging can be ranked from low to high as follows:
- Polyethylene (PE) - This is a common type of plastic used in flexible packaging. While it provides some barrier protection against moisture and gas, it is not completely impermeable.
- Polypropylene (PP) - This is another type of plastic used in flexible packaging. It offers slightly better barrier protection than polyethylene but is still not completely impermeable.
- Polyester (PET) - This material provides a higher level of barrier protection against oxygen and moisture compared to polyethylene and polypropylene. It is commonly used in food packaging to protect against spoilage.
- Nylon (PA) - This material provides an even higher level of barrier protection against oxygen and moisture. It is commonly used in vacuum packaging and for products that require long-term storage.
- Aluminum foil - This material provides the highest level of barrier protection against oxygen, moisture, and light. It is commonly used in flexible packaging for products that require maximum protection, such as pharmaceuticals and sensitive electronic components.
It is important to note that the barrier protection of flexible packaging can also depend on other factors such as the thickness of the material, the manufacturing process, and the specific requirements of the product being packaged.
