<h2>Why Universal Pack for lemon juice packaging?</h2> <p>A reliable lemon juice packaging process is not defined by speed alone. Dose accuracy, liquid control, product acidity, film performance and sealing all need to work together if thousands of small packs are to leave the machine consistently clean and correctly filled.</p> <p>Universal Pack approaches these variables as one integrated process, developing lemon juice stick pack and sachet machines around the actual product, packaging material and production requirements.</p> <h3>Liquid dosing developed around real production conditions</h3> <p>Lemon juice is typically a fast-flowing liquid, but its behaviour can change according to formulation, concentration and filling temperature. The filling system and dosing parameters are therefore configured around the actual product and required dose rather than treating every liquid application in the same way.</p> <h3>Product and packaging material can be tested together</h3> <p>Reliable packaging depends on the interaction between the product, dosing process and flexible packaging material. When required, trials with the customer’s lemon juice and laminate can be used to assess filling behaviour, product cut-off, pack formation and sealing performance before the industrial configuration is finalised.</p> <h3>Multilane technology for industrial output</h3> <p>Universal Pack multilane technology allows multiple lemon juice stick packs or sachets to be formed, filled and sealed simultaneously. The number of lanes and machine configuration are defined according to the required pack dimensions, dose and sustained production output.</p> <h3>More than the primary packaging machine</h3> <p>When the project extends beyond primary packaging, coding, inspection, handling, counting and secondary packaging technologies can be integrated into a complete automated line. Technical support, spare parts and ongoing product and material testing continue throughout the machine lifecycle.</p>

Technical Project Assessment
What should be evaluated before defining a lemon juice packaging machine?
Two lemon juice applications that look similar on paper can require different technical solutions.
The product may be pure juice, juice from concentrate or a formulated preparation. Concentration, pulp content, filling temperature, acidity, required shelf life, pack size and packaging material can all influence how the product should be dosed and sealed.
A detailed assessment at the beginning of the project helps define the correct filling system, pack format, number of lanes and level of automation.
| What we evaluate | Key project considerations |
|---|---|
| How does the lemon juice behave during filling? | Viscosity, flow behaviour and any variation during production are evaluated to define the most suitable dosing system, filling parameters and product cut-off. |
| What type of lemon juice will be packaged? | Pure juice, juice from concentrate, concentrated lemon juice and formulated products can have different physical characteristics. Composition, concentration and the possible presence of pulp or suspended solids are therefore considered from the beginning of the project. |
| Does the product contain pulp or suspended particles? | The type, size and concentration of pulp or other suspended material are assessed to verify compatibility with the dosing circuit, valves and filling nozzles and to maintain consistent filling performance. |
| At what temperature will the lemon juice be filled? | Ambient, chilled, warm or other defined filling conditions can influence product behaviour and the packaging process. The actual production temperature is considered when configuring dosing and sealing parameters. |
| What dose and filling accuracy are required? | Target dose, acceptable tolerance, pack dimensions and product characteristics are assessed together to achieve repeatable filling throughout the production run. |
| How should dripping or splashing be controlled? | Nozzle configuration, filling position, dosing timing and liquid cut-off are evaluated to control a fast-flowing product and help keep the pack and sealing area clean. |
| How does product acidity affect the packaging solution? | The characteristics of the lemon juice are considered when selecting product-contact components, defining the liquid circuit and establishing the appropriate cleaning and maintenance strategy. |
| What shelf life and storage conditions are required? | Expected shelf life, storage conditions and sensitivity to oxygen or light help define the required packaging material characteristics and the overall pack-protection strategy. |
| Which pack format is most suitable? | Stick pack or sachet dimensions, dose volume, opening system, consumer use and branding requirements are considered when defining the final format and machine configuration. |
| Which packaging material will be used? | Laminate structure, sealability, barrier properties, mechanical resistance and compatibility with the product and filling conditions are evaluated to support reliable processing and final pack performance. |
| What production output is required? | Required sustained output, batch size, operating shifts and production campaign duration help determine the appropriate number of lanes, machine speed and level of automation. |
| How many products and pack sizes will be produced? | Different formulations, concentrations, doses and pack dimensions can affect the filling and packaging process. The number of SKUs and expected changeover frequency are considered when defining machine flexibility and format-change requirements. |
| What cleaning requirements must be considered? | Cleaning frequency, production campaign length, accessibility of product-contact parts and changeovers between different formulations are evaluated to define the most appropriate cleaning concept for the application. |
| Which quality controls are required? | Coding, vision inspection, weight control, reject systems, traceability and production data management can be integrated according to the required level of process control. |
| Is secondary packaging part of the project? | Counting, grouping, transfer and cartoning requirements are considered when lemon juice stick packs or sachets need to be integrated into a complete packaging line rather than produced as loose single packs. |
Faq
Can lemon juice be packed in both sachets and stick packs?
Yes. Both formats can be considered for single-dose lemon juice packaging. The choice depends on dose, intended use, pack proportions, opening requirements, packaging material and production targets.
Which dosing system is suitable for lemon juice?
The filling system is selected according to the actual characteristics of the lemon juice, including viscosity, concentration, pulp content, required dose and filling temperature. These parameters are evaluated together rather than selecting a dosing technology solely on the basis of the product category.
Can you package concentrated lemon juice?
Yes, depending on its characteristics. Concentrated lemon juice can behave differently from standard juice during filling, so viscosity, dose, temperature and flow behaviour should be assessed before defining the dosing configuration.
Can lemon juice containing pulp be packaged?
Potentially, yes. The amount, dimensions and characteristics of the pulp or other suspended solids need to be evaluated to verify compatibility with the dosing circuit, valves and filling nozzles and to achieve consistent dosing performance.
How do you prevent lemon juice from dripping into the sealing area?
Nozzle design, dosing timing, filling position and liquid cut-off are configured to control the fast-flowing product as it enters the pack. Limiting dripping and splashing helps maintain a cleaner sealing area and supports consistent pack integrity.
Does the acidity of lemon juice affect the packaging machine?
Product acidity is one of the application parameters considered when defining product-contact components, the filling circuit and the cleaning strategy. The final configuration is established according to the actual product formulation and production conditions.
Can lemon juice be hot filled into sachets?
Applications involving elevated filling temperatures can be evaluated. Filling temperature must be considered together with product behaviour, packaging material, sealing conditions and required production performance before the final machine configuration is defined.
Which films are suitable for lemon juice sachets?
There is no single packaging material suitable for every lemon juice application. Sealability, barrier properties, mechanical resistance, product compatibility, filling conditions and required shelf life should all be considered when selecting the laminate.
How can the packaging help protect lemon juice quality?
The flexible packaging structure can be selected according to the required protection against factors such as oxygen and light. The appropriate barrier level depends on the formulation, processing conditions, distribution chain and targeted shelf life.
Can different lemon juice formulations run on the same machine?
Potentially, yes. Feasibility depends on differences in viscosity, concentration, pulp content, required dose, filling temperature and pack format. These variables are evaluated when defining the operating range and changeover requirements of the machine.
Can sustainable packaging materials be tested for lemon juice?
Yes. Alternative flexible packaging structures can be evaluated through dedicated trials to assess machinability, sealing behaviour and compatibility with the product and required pack performance.
Can the machine be integrated into a complete lemon juice packaging line?
Yes. Lemon juice stick pack and sachet machines can be integrated with coding, inspection, handling, counting and cartoning technologies to create a complete automated packaging line according to the required production flow.
