Aseptic bag-in-box, also known as BIB, is composed of a flexible inner bag made of multi-layer film, a sealed tap changer and a carton. It is widely used in the storage and transportation of fruit juice, dairy products, egg liquid, wine, purified water, and edible oil. and other products. Bag-in-box is gradually replacing traditional rigid packaging as flexible packaging for consumer goods, and is gradually becoming popular all over the world.
 
Pioneered and patented by William R. Scholle in 1955, the bag-in-box was originally used to safely transport battery acid to automotive gas stations and repair shops. Although only started in the automotive industry, this packaging system soon spread to other industries. Bag-in-box technology was extended to food and beverage products after the aseptic filling process was perfected in 1956.
 
Bag: Constructed of layers of film that are sealed together to protect the quality of the product and keep its interior safe from being filled during end use.
Nozzles: are the basis for bag-in-box fittings. This plastic frame opening is sealed in the bag at the time of manufacture and is the entry point for product to be loaded into the bag. After filling, the mouth of the pouch is covered with a simple lid, dispensing tap or connectors and accessories depending on the intended end use.
Fittings: This is a broader category of items including nozzles, caps, valves, etc. It includes anything attached to the mouth of the pocket. Bag-in-box accessories can be anything from a simple cap covering a spout to a complex dispensing valve or connectors and hoses that bridge the gap between the spout/valve and external dispensing equipment.
Box: Outer packaging with lid and bag filled. Mainly corrugated boxes, but it can also be other cardboard boxes or industrial filling iron drums.
 
Use of bag-in-box: the bag is filled with a liquid product and then the accessories are placed to secure the package. The bags are then placed into boxes for safe shipping and distribution.
 
Aseptic bag-in-box is mainly used for filling storage:
jam
Concentrated Juice
egg liquid
dairy products
mineral water

Aseptic bag packaging has gained popularity in various industries, such as food and pharmaceuticals, due to its ability to preserve the quality and freshness of products. These bags are commonly used for packaging liquid or semi-liquid products, ensuring their sterility and extending their shelf life. One prominent feature of aseptic bag packaging is the use of aluminized materials. In this article, we will explore the reasons behind the prevalent use of aluminized materials in aseptic bag packaging.
 
1. Barrier properties:
Aluminized materials, such as aluminum foil, provide excellent barrier properties against light, moisture, oxygen, and other external factors that can compromise the quality and safety of the packaged product. These materials effectively prevent the entry of microorganisms, maintaining the sterility of the contents. The impermeability of aluminized materials helps to ensure the aseptic conditions required for the preservation of perishable products.
 
2. Heat resistance:
Aseptic bag packaging often involves the process of sterilization, which requires high temperatures to eliminate any microorganisms present in the packaging and the product itself. Aluminized materials can withstand these high temperatures without deformation or releasing harmful substances, making them suitable for the sterilization process. The heat resistance of aluminized materials ensures the efficacy of the aseptic packaging process.
 
3. Lightweight and flexible:
Aluminized materials offer the advantage of being lightweight and flexible, making them easy to handle and transport. The flexibility of these materials allows for efficient filling and sealing processes, ensuring the integrity of the packaging. Additionally, the lightweight nature of aluminized materials helps to reduce shipping costs and environmental impact.
 
4. Extended shelf life:
The barrier properties of aluminized materials contribute to the extended shelf life of products. By preventing the entry of oxygen and other gases, these materials inhibit the growth of microorganisms and the oxidation of the contents. This preservation of freshness and quality is crucial, especially for perishable products that need to maintain their nutritional value and taste over an extended period.
 
5. Consumer safety:
The use of aluminized materials in aseptic bag packaging enhances consumer safety. The impermeability of these materials prevents the migration of harmful substances, such as chemicals or contaminants, from the packaging to the product. This ensures that the consumer receives a safe and uncontaminated product, meeting the stringent quality and safety standards.
 
In conclusion, the prevalence of aluminized materials in aseptic bag packaging can be attributed to their exceptional barrier properties, heat resistance, lightweight nature, extended shelf life, and contribution to consumer safety. These materials play a vital role in maintaining the sterility and quality of the packaged products, making them the preferred choice for aseptic bag packaging in various industries.
