Ink, as the soul of the printing industry, its storage method is directly related to the quality and cost of printed matter. Traditionally, ink is mostly stored in iron barrels, which can effectively prevent ink oxidation, volatilization and contamination due to its excellent sealing performance. The surface of the iron drum is covered with an anti-corrosion layer, which can resist the erosion of ink and has strong durability. It has always been the mainstream method of loading ink. However, with the advancement of technology and the increasing awareness of environmental protection, we have begun to explore more efficient and environmentally friendly alternatives.

Aluminum foil bags, with their light appearance and excellent performance, are gradually winning the favor of the printing industry. Aluminum foil bags are used to encapsulate ink. They not only have excellent sealing performance and are convenient for storage and transportation, but also significantly reduce pollution and waste. Aluminum foil bags are ideal for ink encapsulation due to their unique physical properties:

▸High barrier properties: The aluminum foil bag adopts a multi-layer composite material structure (such as PET/AL/PE or PET/AL/PA/CPE), which can effectively isolate the penetration of oxygen and moisture and protect the ink from oxidation and moisture.

▸Light-shielding properties: Aluminum foil bags have complete light-shielding properties, which can effectively block light, prevent the pigments and dyes in the ink from being damaged by ultraviolet radiation, and ensure color stability.

▸Sealing: The aluminum foil bag is sealed using a heat sealing process to ensure the tightness of the bag mouth, effectively prevent moisture intrusion, and maintain the fluidity and printing performance of the ink.

Compared with traditional iron drum packaging, aluminum foil bag packaging shows obvious advantages in many aspects:

▸Cost: The packaging cost of aluminum foil bags is low, and the automatic packaging efficiency of the machine is high; while the packaging cost of iron drums is high, and the efficiency of manual packaging is low.

▸Moisture-proof and anti-oxidation: Aluminum foil bags have excellent moisture-proof and anti-oxidation properties, effectively blocking moisture and air, and maintaining the quality and stability of ink; while iron barrels also have certain moisture-proof and anti-oxidation capabilities, but their sealing performance is relatively weak. Storage may cause the ink to deteriorate.

▸Light protection: Aluminum foil bags can effectively block ultraviolet rays and light, preventing photochemical reactions of the ink during storage; while the light blocking effect of iron barrels is not as good as that of aluminum foil bags, which may cause the ink to change due to the influence of light.

▸Sealing: The aluminum foil bag adopts heat sealing technology, which has good sealing, prevents the ink from contacting the air, and avoids oxidation and deterioration of the ink; while the sealing of the iron barrel is poor, especially after repeated use, which can easily lead to frequent contact between the ink and the air, affecting the its quality.

▸Convenience: Aluminum foil bags are light in weight and small in size, making them easy to transport and store. An appropriate amount of ink can be taken out and the remainder can be sealed and stored to reduce waste; while iron buckets are larger and heavier, making them inconvenient to use and easily causing pollution and waste when handling ink.

▸Environmental protection: Aluminum foil bags comply with RHOS certification, and the materials are recyclable, reducing environmental harm; iron drums are not easy to recycle, and improper handling may cause environmental pollution.

▸Safety: Aluminum foil bags are compact and difficult to leak or break, making them safer during transportation; iron drums are large and heavy, and may leak or break during transportation and handling.     

In this era of efficiency and environmental protection, aluminum foil bag packaging provides a new solution for the storage and use of ink with its excellent performance and environmental protection characteristics. It not only improves the storage quality of ink and reduces costs, but also reduces the impact on the environment. It is the best choice for the printing industry to move towards a green future.
