Bag-in-Box Filling Machines

Bag-in-box (BiB for short) is a flexible packaging system for liquid products. It consists of a multi-layered bag with a valve or tap, which is contained within a sturdy cardboard box. Bag-in-box packaging is used in many industries – especially where hygienic filling, long shelf life, and efficient processes are required.

Bag in Box is suitable for a variety of liquid products from the food and non-food sectors, for example:Drinks: Juice, water, milk, plant-based drinks, syrup, iced teaFoodstuffs: Cooking oils, sauces, concentrates, liquid ingredientsNon-food: Cleaning and disinfecting agents, chemicals, technical fluids, cosmetics

Bag-in-Box offers numerous advantages for manufacturing companies:Hygienic, closed system for filling and dispensing.Reduced oxidation due to airtight bagLonger product shelf lifeEfficient logistics thanks to low weight and compact formatAutomatable filling processes with modern machine technology

The quality and efficiency of bag-in-box packaging depend significantly on the filling technology. Modern bag-in-box filling machines ensure:Precise and reproducible fill quantitiesHygienic and safe valve handlingHigh process reliabilityScalability from small to large production runs

Yes. Bag-in-box systems and filling lines can be designed to meet all relevant food law requirements. Aseptic filling solutions are also available for sensitive products.

Shelf life depends on the product, material, and filling method:Unopened, many products have a shelf life of several months to over a year.Once opened, the collapsible bag protects the contents from air ingress, thus extending the usage period.

Bag-in-box technology is feasible in many volume ranges:Small containers from approx. 1 literStandard sizes such as 3, 5 or 10 litersBulk containers from 20 liters for industry and large consumers

Bag-in-box packaging is considered a resource-saving alternative to rigid packaging:Reduced material usageLess transport weight and emissionsCardboard packaging is usually fully recyclableReduced waste volume after use

For optimal results, use bag-in-box containers:Store in a cool, dry placeProtect from direct sunlightProcessed according to product-specific specifications

Bag-in-Box is successfully used in:Food and beverage industryChemical and cleaning agent industrycosmetics and pharmaceutical-related environmentCatering, institutional food service and trade

Oettel Maschinen GmbH develops and supplies customized machine solutions for filling bag-in-box systems. Customers benefit from:Years of experience in mechanical engineeringIndividual, practical solutionsMany custom solutions are possibleHigh process reliability and qualityPersonal consultation and technical support

Standard filling machines are pre-configured machine solutions for defined containers and performance ranges. They are characterized by:short delivery timesclear performance dataeconomic investment costs

1. Robust machine designOur standard filling machines are based on a robust stainless steel frame construction instead of lightweight sheet metal construction. This ensures:high long-term stabilitylow-vibration operationConsistent accuracy even at higher clock speedslower susceptibility to errorsResult: longer service life and consistent process quality.2. Sophisticated control and automation technologyOettel relies on clearly structured PLC programs with a focus on process reliability:reproducible filling processesMonitoring of filling times and parametersPrepared interfaces for later automationRemote maintenance option3. High process reliabilityPrecise bottling is not a matter of chance, but the result of meticulously designed technology:defined media managementno dead dreamsstable filling parametersminimized residual quantitieslow rejection ratesThis is especially important for valuable media or sensitive products.4. Media and packaging diversityOur bottling machines are designed for:different viscositiesFood and non-food applicationsBag-in-Box, stand-up pouches and cheerleadersATEX variants for potentially explosive atmospheresOne machine – many applications5. Upgrade and lifecycle conceptOettel does not consider standard machines as a final solution, but as a basis:Later automation possibleIntegration into packaging linesRetrofitting of conveyor technologyRetrofit instead of replacement investmentInvestment security for many yearsComparison: Classic standard machine vs. OettelCriterion Classic standard solution Oettel standard filling machine:Stainless steel tubular frame constructionBasic PLC control system, expandable automationProcess functionally reproducible & monitoredFlexible containers (BIB, pouch, cheertainer, canister, big bag)Upgradeable in the future
