Advantages of bag-in-box
Longer shelf life: The bag-in-box design prevents air from entering the package, which can help preserve the freshness of the product for a longer period of time.
Ease of use: Bag-in-box packaging is easy to handle and store, making it a popular choice for both consumers and businesses. It is also easy to dispense the contents of the package without spills or mess.
Cost-effective: Bag-in-box packaging is often less expensive than other types of packaging, such as glass bottles or aluminum cans. It also allows for efficient shipping and storage, reducing costs for manufacturers and distributors.
Environmentally friendly: Bag-in-box packaging uses less material than other types of packaging, making it a more sustainable option. It also creates less waste than traditional packaging, such as glass or plastic bottles.
Versatile: Bag-in-box packaging can be used for a variety of products, including liquids, powders, and even frozen products. It is also available in a range of sizes, making it suitable for both small and large quantities.
Improved product quality: Bag-in-box packaging can help preserve the quality of the product by protecting it from exposure to light, air, and other contaminants that can degrade its flavor, aroma, and texture.
Convenient storage: Bag-in-box packaging is easy to stack and store, making it a great option for businesses with limited storage space. It also takes up less space on store shelves, allowing retailers to display more products.
Customizable design: Bag-in-box packaging can be customized with logos, graphics, and other branding elements, helping to enhance the product's visual appeal and increase brand recognition.
Easy disposal: Bag-in-box packaging is easy to dispose of and can be recycled, making it a more eco-friendly option than other types of packaging. It also reduces the amount of waste generated by the product.
Reduced risk of contamination: Bag-in-box packaging is sealed and tamper-evident, reducing the risk of contamination from outside sources. This is particularly important for food and beverage products that need to meet strict safety and quality standards.
Features of Bag-In-Box
Bag-in-box packaging utilizes a box, bag, and fitment to transport and dispense liquid products both efficiently and without contamination.
Bag: The bag is constructed from layers of film that are sealed together and designed to protect the product quality and keep it safe inside from filling through end use.
Spout: The foundation of our all bag-in-box fitments, this plastic-framed opening is sealed into the bag when it’s made and is the entry point for filling the product into the bag. After filling, bag spouts are covered by either a simple cap, dispensing tap, or connector and fitment depending on their intended end-use.
Fitment: This is a broader category of items including spouts, caps, valves, and more. It encompasses anything that attaches to the bag spout. Bag-in-box fitments can be anything from simple caps that cover a spout, to sophisticated dispensing valves or connecters and hoses that bridge between the spout/valve and outside dispensing equipment.
Box: the outer package that holds the capped and filled bag. This can be anything from a simple cardboard box to an industrial-sized steel drum.
The bag is first filled with liquid product, and then a fitment is placed to secure the packaging. The bag is then placed in a box to ensure safety in transportation and dispensing.
Films for Bag-In-Box
There are various material structure options available for bag-in-box packaging, depending on the specific application and requirements. Some common material structures include:
Multi-layered films: Multi-layered films are the most common material structure used for bag-in-box packaging. These films are made up of several layers of different materials, each providing specific functional properties such as strength, barrier properties, puncture resistance, and flexibility.
Barrier films: Barrier films are designed to provide a high level of protection against oxygen, moisture, light, and other environmental factors that can affect the product's quality and shelf life. These films are often used for products that require extended shelf life, such as wine, juice, and dairy products.
Metallized films: Metallized films are made by depositing a thin layer of metal onto a plastic film. These films provide an effective barrier against oxygen and light and are often used for products that require high barrier prtection, such as wine and juice.
Foil laminates: Foil laminates are made by laminating a layer of foil between layers of plastic film. These laminates provide excellent barrier properties against oxygen, light, and moisture and are often used for products that require extended shelf life, such as wine and juice.
Paper-based laminates: Paper-based laminates are made by laminating a layer of paper between layers of plastic film. These laminates provide a natural, eco-friendly look and feel and are often used for products that require a sustainable packaging solution, such as coffee and tea.
Valve Options for Bag-In-Box
There are several valve options available for aseptic bag-in-box packaging, depending on the specific application and requirements. Some common valve options include:
Vitop® valve: This is a popular option for bag-in-box packaging, and it is widely used in the food and beverage industry. The Vitop® valve is a low-profile, tamper-evident valve that is easy to install and use.
Scholle IPN valve: The Scholle IPN valve is another commonly used valve for bag-in-box packaging. It features a patented one-piece design that reduces the risk of contamination and ensures consistent flow.
Liqui-Box Pure-Flo valve: The Liqui-Box Pure-Flo valve is designed for aseptic filling applications and features a sterile, disposable design. It is easy to install and provides excellent flow control.
Rapak Intasept® valve: The Rapak Intasept® valve is a sterile, aseptic valve that is designed for use in high-purity applications. It features a tamper-evident design and is easy to install and use.
Z-Valve™: The Z-Valve™ is a compact, low-profile valve that is designed for use in aseptic bag-in-box packaging. It is easy to install and provides excellent flow control.
Cheertainer valve: The Cheertainer valve is a low-cost, disposable valve that is commonly used in the pharmaceutical and healthcare industries. It is designed for single-use applications and is easy to install and use.
