In the oil and fat industry, packaging materials and processes play an important role in product protection, storage, transportation, and handling. For products such as edible fats, shortening, margarine, and other semi-solid fats, lined carton packaging provides a practical solution for bulk packaging and distribution.
To support these packaging requirements, MITTIWAY provides an automated packaging solution integrating a Carton Bag Inserter and a Carton Bag Lifting & Sealing Machine. By automating the inner bag insertion and sealing processes, the solution helps streamline packaging operations and improve consistency throughout production.
The integrated solution combines two key pieces of equipment to handle the inner bag packaging process before and after product filling.
The Carton Bag Inserter automatically places a pre-made liner bag into an erected carton, preparing the container for product filling.
By reducing manual bag placement, the machine helps improve packaging consistency and reduces repetitive operator tasks. The inner bag provides a packaging barrier between the product and the carton, helping protect the carton from direct contact with the oil or fat product.

After the carton is filled, the Carton Bag Lifting & Sealing Machine lifts and positions the liner bag for the subsequent sealing operation.
This process helps organize the bag opening, facilitate consistent sealing, and prepare the packaged product for downstream handling. Automating bag positioning and sealing also reduces the need for repetitive manual handling.


Improved Packaging Consistency
Automated inner bag insertion and bag handling help establish a more repeatable packaging process, reducing variations associated with manual operations.
Enhanced Product Protection
The inner bag acts as a liner between the product and the carton. Proper bag positioning and sealing help contain the product and reduce the risk of leakage, subject to the selected bag material and sealing process.
Reduced Manual Handling
Automating key bagging and sealing operations helps reduce repetitive manual tasks and supports a more organized production workflow.
Flexible Packaging Integration
The two machines can be configured to work with upstream filling equipment and downstream carton closing and palletizing systems, depending on the customer's production requirements.
Different oil and fat products have different packaging characteristics. Product viscosity, filling temperature, bag material, carton dimensions, and sealing requirements all influence the design of an effective packaging line.
MITTIWAY focuses on automated carton packaging equipment and customized packaging solutions. By integrating carton bag insertion and bag lifting and sealing technologies, MITTIWAY helps manufacturers explore more efficient and consistent approaches to bulk oil and fat packaging.
