Irregular Shape Liquid Packaging Machine

Okay, a non-standard bag/irregular shape packaging machine is an automated device specifically designed for packaging irregularly shaped bags (non-traditional three-side seal or four-side seal bags). It is widely used in the food, daily chemical, pharmaceutical, and pet food industries.

Its core features can be summarized in four aspects: technology, packaging effect, production efficiency, and applicability:

1. Unique Bag Forming Device: This is the most crucial feature. Unlike standard back-seal or three-side seal bag forming devices, non-standard bag forming devices are typically complex three-dimensional forming devices. Through specially designed molds and folding methods, they can shape flat films into special shapes such as stand-up pouches (with bottom gussets), stand-up pouches with spouts, four-side seal bags, gusseted bags (with side pleats), handle bags, and non-standard top-seal bags.

2. Multi-axis Servo Drive System: To achieve complex bag cutting and precise sealing trajectories, multiple servo motors are typically used for coordinated control. This ensures the accuracy of cutting and sealing even at high speeds.

3. Flexible Cutting and Sealing Device: Equipped with custom-shaped cutting blades (customizable to bag shapes) and matching custom-shaped heat-sealing devices. The sealing path is not a simple straight line but may include curves, arcs, etc.

4. Powerful Control System: Utilizes an advanced PLC and touchscreen human-machine interface, capable of storing parameter formulas for multiple bag types, easily recalled with a single click when switching products.

1. Aesthetics and Uniqueness: Produces novel and attractive packaging with high shelf recognition, a powerful tool for brand differentiation marketing.

2. Functional Design: Enables multiple practical functions:

◦ Self-standing: Bags can be displayed upright for better display.

◦ Easy opening and resealing: Such as zippers, spouts, screw caps, etc.

◦ Portability: Includes handle design.

◦ Enhanced experience: Such as spout bags for convenient direct drinking.

3. Excellent Shelf Display Effect: The three-dimensional bag shape provides a larger display area, making printed patterns more eye-catching.

1. High Automation: From film unwinding, forming, metering and filling (powder, granules, liquid, block), sealing, cutting to finished product output, the entire process is automated, saving significant labor costs.

2. High Efficiency: Although the speed is generally lower than simple back-sealing machines, the efficiency is greatly improved compared to manual or semi-automatic packaging, meeting the needs of mass production.

3. Wide Material Adaptability: It can handle various composite film materials, such as PET/PE, PET/AL/PE, NY/PE, etc., to meet the product's requirements for barrier properties, freshness preservation, and puncture resistance.

4. Formula-Based Management: Quick changeover, reducing downtime.

1. Strong Product Targeting: Particularly suitable for products requiring differentiated packaging and increased added value, such as high-end snacks, pet food, laundry detergent pods, liquid condiments, specialty coffee, wet wipes, disposable daily chemical products, etc.

2. Higher Initial Investment: The cost of the machine itself and customized molds is much higher than that of standard bag packaging machines.

3. High requirements for operation and maintenance: The mechanical structure is relatively complex, requiring more specialized technicians for debugging and maintenance.

4. Changeover time: Although the formula is adjustable, changing to completely different shaped bags may still require replacing some physical molds (such as the bag maker and cutter), which takes time.
