Automatic Gable Top Carton Filling Machine for Milk and Yogurt

Product Introduction: Gable-Top Carton Filling Machine

This automatic gable top carton filling machine provides an integrated packaging solution for milk, yogurt, cultured dairy drinks, and other compatible liquid products. Designed for 200–1000 ml cartons, the system combines carton forming, bottom heat sealing, precise filling, top sealing, optional cap application, and date coding within one coordinated process. A large-capacity hopper supplies product to the pneumatic filling section, while dedicated heating components create smooth, secure carton seals.

The machine supports cold filling at 2–50°C and hot filling at 80–92°C, allowing manufacturers to adapt the packaging process to different product requirements. A PLC control system simplifies parameter adjustment and daily operation, while food-grade stainless steel construction supports hygienic production and convenient cleaning. Cardboard and aluminum-foil laminated cartons can be processed, with carton dimensions customized for the selected package. This configuration is well suited to dairy processors seeking efficient automated carton packaging with flexible filling and sealing capabilities production requirements.

Packaging Process

The machine organizes the main carton packaging operations into a continuous sequence:
Carton Feeding → Carton Forming → Bottom Heating → Bottom Sealing → Filling → Cap Application (Optional) → Top Heating → Top Sealing → Date Coding → Finished Carton Output
This integrated process helps reduce manual handling while maintaining consistent carton movement through each packaging stage.

Dairy Packaging Line Integration

The carton filler can operate as the final packaging section of a broader dairy processing line. Depending on the project, upstream equipment may include:
Milk Processing → Mixing → Homogenization → Pasteurization → Buffer Storage → Carton Filling → Sealing → Coding → Secondary Packaging
The complete line configuration should be determined according to product type, processing capacity, filling temperature, and required shelf life.

Technical Specifications

Key Features

• Integrated Carton Packaging Process
  The machine brings carton forming, bottom sealing, liquid filling, top sealing, optional capping, and date coding together in one automated system, reducing separate packaging operations.
• 200–1000 ml Filling Range
  Designed for 200–1000 ml gable top cartons, the machine can accommodate different portion sizes for milk, yogurt drinks, and other dairy products.
• Cold and Hot Filling Capability
  The system supports cold filling from 2–50°C and hot filling from 80–92°C, providing flexibility for products with different processing and packaging requirements.
• Reliable Bottom and Top Sealing
  Dedicated heating components are used at the carton sealing sections to create smooth and secure sealing edges. Stable sealing helps maintain package integrity during handling and distribution.
• Pneumatic Liquid Filling
  A large-capacity hopper supplies the filling section, while the pneumatic filling mechanism provides controlled product delivery into each carton.
• Optional Carton Capping
  A cap application system can be added when screw-cap gable top cartons are required, allowing the packaging format to be adapted to different retail and consumption needs.
• PLC Control System
  The integrated PLC control system allows operators to adjust operating parameters according to the actual carton and product requirements, simplifying daily production control.

Milk Packaging

For fresh milk and other flowable milk products, the machine provides automatic carton forming, filling, and sealing in one compact packaging process.
Both filling temperature and carton configuration can be selected according to the actual milk processing method.

Yogurt and Cultured Dairy Packaging

The machine can also be configured for drinking yogurt, fermented milk beverages, and other compatible fluid dairy products.
For thicker yogurt formulations, product viscosity and flow characteristics should be confirmed before selecting the filling configuration.

Flexible Carton Size Customization

Carton dimensions are not limited to one fixed specification. The packaging section can be customized around the selected carton within the 200–1000 ml filling range.
Before manufacturing, it is recommended to provide the carton drawing or physical packaging sample for compatibility confirmation.
