Packaging in Bag in Box has revolutionized the way liquids are preserved and distributed, especially those sensitive to factors like light, oxygen, and temperature. This technology offers multiple benefits, from storage convenience to reduced transportation costs. However, improving the shelf life of liquid products requires a technical approach involving the selection of appropriate filling machines, optimization of the filling process, and proper post-packaging handling.

In this article, we will explore how Cartobol‘s solutions—such as fillers, case formers, and sealers—can significantly improve the durability of Bag in Box liquid products, ensuring optimal preservation over time.

Factors Affecting Durability

• Oxygenation and Oxidation: Oxygen is one of the biggest enemies of liquid products, as it accelerates oxidation, affecting the taste and quality of products like wine, juices, and oils. To prevent this, it is essential to use filling machines that minimize oxygen exposure during the process, thus ensuring a longer product shelf life.
• Filling Temperature: Temperature control during the filling process is crucial, especially for sensitive liquids like wine or oils that can degrade when exposed to improper temperatures. Precise temperature management during filling helps prevent such changes.
• Hygiene in the Filling Process: Microbiological contamination is another major concern. Aseptic fillers ensure a hygienic and safe process, protecting the product from contaminants that could reduce its durability.

Solutions to Improve Durability

Automating the filling process is one of the most important steps to increase the shelf life of liquids in Bag in Box. We offer a wide range of fillers to meet various production needs. From manual to automatic options, each machine is designed to ensure precise, hygienic, and efficient filling.

• Manual Fillers: Cartobol’s manual fillers, such as the ECOFILL EASY START ARM and ECOFILL EASY START STD, are ideal for small to medium production runs. They offer a simple and cost-effective solution, ensuring quality packaging with human control over the process. The ECOFILL ATEX is specifically designed for environments requiring additional control due to flammable or explosive materials.
• Semi-Automatic Fillers: To enhance efficiency without losing control over the process, Cartobol offers semi-automatic fillers like ECOFILL PROBOX, ECOFILL HT1 SW FULL ACTION, and ECOFILL HT2 SW FULL ACTION. These machines allow for higher production volumes and fewer errors while maintaining the precision needed to preserve product quality.
• Automatic Fillers: For large-scale production, Cartobol’s automatic fillers such as the ECOFILL MASTER and ECOFILL MASTER ASEPTIC are ideal choices. These machines feature advanced systems like aseptic filling and oxygen control, ensuring a fully sterile and accurate process. Automatic Bag in Box Lines further optimize production, increasing output and reducing human intervention, which results in faster and safer packaging.

Enhanced Durability with Oxygen Control

One of the main factors affecting the durability of liquid products is oxygen exposure, which accelerates oxidation and product degradation. To extend shelf life, it is essential to use packaging systems that control oxygen levels within the container. Automatic and semi-automatic fillers, such as the ECOFILL MASTER ASEPTIC, are equipped with technology that minimizes this exposure, preserving the liquid’s quality and freshness for longer.

• Box Forming and Sealing Solutions: In addition to the filling process, Bag in Box packaging includes how the boxes are sealed and stored. Solutions are also available to optimize this step, ensuring that liquid products remain safe and protected during transport and storage.
• Bag in Box Case Formers: Cartobol’s case formers, such as the ECOPACK MASTERFORM SV, are compact, easy to operate, and designed for fast format changeovers without tools. This is key for maintaining production efficiency without compromising packaging safety and quality.
• Bag in Box Case Sealers: Sealing the boxes is also critical to ensure the durability of liquid products. Automatic sealers such as ECOPACK HOTMELT and ECOPACK SCOTCH CBL use two side adhesive bands to ensure a uniform, airtight seal. This type of closure prevents the entry of air and other contaminants that could affect product quality.

• Pressurized Tanks for Bag in Box Filling: The use of pressurized tanks is another key solution to improve the durability of Bag in Box liquid products. These tanks allow for high, consistent flow transfer without stressing the liquid, which is vital for delicate products like wine or oils. We offer pressurized buffer tanks, such as the 100L BUFFER TANK and 200L BUFFER TANK, equipped with advanced features like touch screens, pressure probes, and level radars to ensure optimal performance.
• Filtration Equipment: Filtration is also crucial to ensure the purity and long-term preservation of liquids. Notably, the PALET FILTRATION C3 and PALET FILTRATION C4 are ideal for the wine industry, where product quality is paramount. These systems help remove impurities and keep the liquid fresh at all times.

Strategies to Improve the Durability of Wine, Juices, and Oils

Each type of liquid presents unique challenges regarding preservation and shelf life. Below are some specific strategies to improve durability:

• Wine: Wine is particularly sensitive to oxidation, which can alter its taste and aroma. To enhance wine durability in Bag in Box, it’s crucial to use automatic aseptic fillers that control oxygen and maintain optimal temperature during filling. Additionally, using pressurized tanks and airtight box sealing are essential to prevent wine from coming into contact with air.
• Juices: Juices, especially natural ones, can lose freshness quickly due to high acidity and oxygen exposure. To extend their shelf life, it’s vital to use aseptic filling machines and maintain controlled temperature throughout the packaging process. Also, filtration systems ensure juices remain pure and free from impurities.

• Oils: Oils, particularly olive oil and other vegetable oils, are highly susceptible to oxidation. To improve their durability, it’s essential to use fillers with oxygen control and store them at low temperatures in light-free environments.

Conclusion

Improving the durability of products depends not only on the filling process but also on packaging optimization, oxygen control, temperature, and hygiene. Our advanced solutions, such as automatic fillers, case formers and sealers, and pressurized tanks, are essential to ensure the quality and shelf life of products like wine, juices, and oils. By implementing these technologies, companies can ensure more efficient, safer, and longer-lasting packaging for their liquid products.
