1235-O Aluminum Foil for Flexible Packaging

 

In the current era of upgrading and iteration in the flexible packaging industry, high barrier properties, high safety, ease of processing, and durability have become core selection criteria for high-end packaging materials.

Aluminum foil, as the core barrier substrate for composite flexible packaging, is widely used in food, pharmaceutical, and daily chemical industries due to its unique advantage of dense metal structure. Among them, the 1235 aluminum foil has balanced performance and strong processing adaptability, making it a benchmark material for mid-to-high-end flexible packaging.

1. Properties of 1235 Aluminum Foil Jumbo Roll

1235 aluminum foil belongs to the 1-series high-purity aluminum foil and is a classic grade for flexible packaging. Industry standards stipulate that its aluminum content should not be less than 99.35%. Its extremely low impurity content gives it a purity level not found in alloy aluminum foils such as 8011 and 8079, providing a solid performance foundation for high-end packaging applications.

This material possesses exceptional barrier protection capabilities. The high-purity aluminum, after rolling, has a dense, non-porous structure, effectively blocking oxygen, moisture, ultraviolet rays, dust, and microorganisms, fundamentally preventing problems such as oxidation and deterioration of the packaged contents, moisture absorption and clumping, and flavor loss. Its barrier properties are unaffected by normal temperature and humidity, ensuring a stable internal packaging environment and significantly extending product shelf life. It is a core substrate for long-term preservation of food and pharmaceuticals.

In terms of safety, 1235 aluminum foil possesses high food-grade standards. The material is odorless, does not leach heavy metals, and is chemically stable, not reacting with food, pharmaceuticals, or daily chemical raw materials. It fully complies with domestic and international food contact and pharmaceutical packaging safety standards, allowing direct adhesion to contents and mitigating contamination risks from the material itself. Its safety is far superior to ordinary packaging films.

Furthermore, 1235 aluminum foil boasts excellent processing adaptability. Its balanced thermal conductivity, temperature resistance, and sealing performance make it suitable for mainstream flexible packaging processes such as high-temperature lamination, heat sealing, and high-temperature sterilization. Moreover, its lightweight and thin material does not increase packaging weight, aligning with the industry's trend towards lightweight, low-cost, and environmentally friendly development, balancing quality and cost-effectiveness.

2. O temper for flexible packaging

The flexible packaging industry almost exclusively uses 1235 o aluminum foil, rather than rigid materials. The core reason is that the physical properties of the O-state precisely meet the needs of flexible packaging in all application scenarios.

Firstly, it is highly flexible and tough, resistant to breakage. A fully annealed process eliminates internal stress, resulting in a soft texture and excellent ductility. It exhibits no pinholes or cracks after frequent bending and rubbing, and can freely deform with the composite film, eliminating packaging barrier failure issues.

Secondly, it boasts stable composite performance. Its smooth, even surface and uniform tension enhance adhesion to adhesives and plastic films. The resulting layers adhere tightly, preventing bubbling and delamination, effectively improving the overall structural strength and lifespan of the packaging.

Thirdly, it exhibits low production losses. It is less prone to tape breakage and wrinkling during the entire process of slitting, printing, bag making, and heat sealing. The edges are smooth, and the sealing performance is stable, significantly reducing the scrap rate and making it suitable for large-scale industrial production.

Fourthly, it is durable and damage-resistant, able to withstand external forces such as compression, friction, and minor punctures during transportation and use, continuously and stably maintaining its barrier protection effect.

3. Applications of 1235 Aluminum Foil Flexible Packaging

• In the food industry, it can be used for freshness-locking packaging of dried goods such as milk powder, tea, and nuts, as well as high-temperature retort pouches for cooked foods and braised dishes. It is also suitable for composite packaging of various snack foods.

• In the pharmaceutical industry, it is suitable for blister packs for tablets and capsules, sealed pharmaceutical bags, and packaging for sterile medical consumables. Its high purity and high barrier properties ensure the stability of drug properties and the sterility and safety of consumables.

• In the daily chemical and cosmetics industry, it is widely used in stand-up pouches and tube packaging for serums, masks, and personal care products. It prevents the oxidation and deterioration of active ingredients and supports high-definition printing, balancing practicality and aesthetics.

• Furthermore, it can be used for special packaging in precision electronics, fine chemicals, pet food, and agricultural products, providing moisture-proof, rust-proof, anti-static, and oxidation-proof protection, with extremely strong adaptability to various scenarios.

Aluminum Foil: An Indispensable Part of Flexible Packaging

 Aluminum foil packaging makes it more convenient to pack food in the right amount. Therefore, food can be prepared and consumed as needed, thus reducing waste. At the same time, it also ensures the nutritional content and health needs of the product. Smaller packaging prevents product damage and wastage compared to larger packaging, thus saving resources overall.

However, in food packaging, aluminum foil is rarely used alone because aluminum foil itself has some shortcomings. For example, as aluminum foil is further thinned, the number of pores will increase, which will affect the barrier properties of the flexible packaging foil. sually, aluminum foil can be combined with other packaging materials to make composite packaging materials to make up for the shortcomings of aluminum foil, thereby improving the comprehensive packaging performance of composite packaging materials.

Aluminum foil is an important component of flexible packaging materials. Aluminum foil can block light, oxygen, moisture and bacteria, so it is widely used in food and pharmaceutical packaging. Aluminum foil can also play a role in beautifying products and improving product quality. Aluminum foil flexible packaging is mainly used for food bags, beverages, candy, chocolate, and cooked food. The thickness of aluminum foil used in flexible packaging is usually between 7 and 9 micron.

8079 and 1235 aluminum foil both have a wide application in flexible packaging. Due to their excellent characteristics, they both have a certain status in flexible packaging. 8079 aluminum foil is widely used in food and drug packaging, electronic and electrical appliance packaging and household daily necessities. The aluminum content of 1235 aluminum foil is more than 99.35%. It is also a kind of pure aluminum foil and is widely used in cables, tapes, and battery foils.

The surface of food grade aluminum foil is extremely clean and hygienic. No bacteria or microorganisms can grow on the surface. It is a non-toxic packaging material that can be in direct contact with food without any danger to human health. Haomei food aluminum foil has undergone multiple tests for bacteria, mold, etc., and the heavy metal does not exceed 0.25 parts per million. It strictly implements industry standards and reaches food-grade aluminum foil standards, which is harmless to the human body.
