Industrial Aluminum Barrier Bags | Moisture-proof, Gas Barrier, Light Shielding / Large Size, Flexible Container Inner Bag Compatible

MATAI TRADING (THAILAND) CO., LTD. handles aluminum bags used for packaging powders, chemicals, resin raw materials, and industrial materials where quality deterioration due to moisture absorption and oxidation needs to be avoided.

With a multilayer structure including aluminum foil and aluminum vapor deposition films, they help maintain the quality of the contents by suppressing the effects of moisture, oxygen, light, and odor. We support not only small packaging but also large-capacity industrial applications such as large gusset bags and inner bags for flexible container bags. For large aluminum bags used in Thailand, we consider the dimensions and structure according to the contents, filling amount, outer container, and filling/discharging methods, and supply them in cooperation with production sites in China.

■　Reasons to Choose Aluminum Bags

For resin raw materials and powders that easily absorb moisture, and industrial materials that are easily affected by oxidation, the moisture and outside air during transportation and storage can alter the quality of the contents. An aluminum bag is a packaging material with a multilayer structure that combines aluminum foil or aluminum vapor deposition film with a resin film to enhance moisture-proof, gas barrier, and light shielding properties.
Compared to general polyethylene bags, it is easier to suppress the permeation of water vapor and oxygen from the outside, making it suitable for applications where you want to protect the contents from the external environment, such as storage in high temperature and high humidity environments or long-distance transportation. It can also be used for applications to suppress the permeation of odors, and the constituent materials are selected according to the storage conditions required for the contents.

■　Main Applications

Aluminum bags can be used in various industrial applications that require moisture-proofing and barrier properties.

• Resin raw materials and engineering plastics that easily absorb moisture
• Chemical raw materials such as powder chemicals and additives
• Industrial films, electronic and industrial materials
• Contents requiring moisture-proofing and flavor retention, such as food powders and food raw materials
• Other raw materials and products where you want to suppress the effects of moisture, oxygen, light, odor, etc. Since the required barrier performance and inner material specifications differ depending on the contents, we consider the material structure according to the application. For applications where the contents come into direct contact with the packaging material, such as food, we select the specifications after confirming the film structure to be used and the required standards.

■　Multilayer Structure and Barrier Performance

Aluminum bags combine barrier properties, strength necessary as a packaging material, and heat sealability by laminating films with different characteristics. Typical structure examples are as follows:

PET is used as the outer layer to supplement mechanical strength and dimensional stability, and Ny is used to improve impact resistance and puncture resistance.
AL is aluminum foil, used as a barrier layer to significantly suppress the permeation of water vapor, oxygen, light, etc.
VMPET is an aluminum vapor deposition polyester film, used for applications that impart light-shielding and moisture-proof properties. Since the barrier performance differs from structures using aluminum foil, it is selected according to the required performance.
PE is mainly used for the inner layer and plays the role of sealing the bag by heat sealing.

■　Support for Large Sizes and Flexible Container Inner Bags

We can manufacture aluminum bags tailored to industrial applications by making bags from large aluminum laminate films.

In addition to large gusset bags, we also support large aluminum bags used as inner bags for flexible container bags. By combining it with the exterior of a flexible container bag, it is possible to design a packaging where the outer flexible container bag secures the strength necessary for cargo handling, and the inner aluminum bag provides moisture-proofing and gas barrier properties.

Dimensions and shapes are considered according to the outer container, filling amount, contents, filling equipment, discharging method, etc.

Even when a large aluminum bag is required, you can consult with us not only about standard dimensions but also about sizes tailored to the actual usage conditions.

■　Supply and Custom-made Support in Thailand

MATAI TRADING (THAILAND) CO., LTD. acts as a contact point in Thailand and proposes large aluminum bags after confirming the application and required specifications.
Since facilities capable of manufacturing large aluminum bags are limited in Thailand, large products are supplied in cooperation with production sites in China.
The width, length, shape, film structure, etc., of the bag can be considered individually according to the contents and the outer container.
Please also consult us about custom-made products according to your usage conditions, such as wanting to enhance moisture proofing, use it as an inner bag for a flexible container bag, or manufacture it in a large size.

■　Purchase and Inquiries

If you would like large aluminum bags, aluminum inner bags for flexible container bags, or specific dimensions and film structures, please contact MATAI TRADING (THAILAND) CO., LTD. We will confirm the contents, required quantity, bag size, outer container, required barrier performance, etc., and propose specifications suitable for your application.

• Product specifications and available film structures vary depending on the size, application, contents, production conditions, etc. Please contact us for details.

■　Frequently Asked Questions

Q1: Can you manufacture large aluminum bags to be used as inner bags for flexible container bags?
A1: Yes. We can consider the dimensions and structure of the aluminum inner bag according to the outer container such as a flexible container bag, filling amount, and usage conditions.

Q2: Can you support large sizes?
A2: Yes, we can support them. You can consult us about large bag making for industrial applications, such as large gusset bags and inner bags for flexible container bags.

Q3: Can it be used for packaging resins or powder chemicals that easily absorb moisture?
A3: Yes. With a multilayer structure containing aluminum foil or aluminum vapor deposition film, it suppresses the permeation of water vapor, etc., and can be used for packaging raw materials that require moisture-proofing. We select the film structure according to the required performance.

Q4: What is the difference between the aluminum foil type and the aluminum vapor deposition type?
A4: Both can impart moisture-proof and light-shielding properties, but the material structure and barrier performance are different. If high barrier properties are required, a structure containing aluminum foil is used. Depending on the required performance and application, a structure using aluminum vapor deposition film may be selected, tailoring it to the usage conditions.

Q5: Can it also be used for food raw materials?
A5: It can also be used for packaging food powders, food raw materials, etc. When in direct contact with the contents, we select the specifications after confirming the materials used and the required standards.
