Automatic Irregular Pouch Packaging Machine Custom-shaped Pouch Filler

Machine Introduction

This machine is a high-performance tool in modern packaging industry, specially designed to efficiently, accurately, and hygienically fill liquids, pastes, and sauces (such as shampoo, soy sauce, edible oil, juice, pesticides, lubricants, etc.) into pre-formed plastic film bags and complete the sealing process. Its core working principle can be summarized as: “bag forming – filling – sealing,” continuously and automatically completed in an integrated operation.

Technical Parameters

Written by Eric Sanders, Custom Packaging Solutions Architect at Hangzhou Ruiyi Machinery Technology Co., Ltd. Over 14 years, I have engineered specialized pouch packaging systems for brands requiring non-standard bag shapes, working with clients in cosmetics, food, and pharmaceutical sectors across 28 countries.

What This Machine Does

The Ry-120YLB-F is a vertical form-fill-seal machine designed to produce custom-shaped and irregular pouch formats that stand out on retail shelves. Unlike standard rectangular sachet machines, this unit can form specialty shapes including contoured pouches, angled-bottom bags, and brand-specific silhouettes. It fills liquids, pastes, and sauces with volumes from 1 to 500ml at speeds of 30 to 80 bags per minute, combining distinctive packaging aesthetics with efficient production throughput.

How Custom-Shaped Pouch Forming Works

The film roll feeds into the machine through a forming collar engineered for the target pouch shape. As the film passes through, the forming collar creates the custom contour, whether it involves angled seals, curved edges, or asymmetric designs. Vertical sealing jaws create the back seal, while the horizontal sealing jaws close the bottom of each pouch. The filling system then dispenses the measured product into the formed pouch through a nozzle sized for the pouch opening. After filling, the horizontal jaws seal the top of the pouch and simultaneously form the bottom seal of the next unit. A precision cutting mechanism separates each finished pouch along the contour line, producing clean, professional-looking custom shapes ready for retail display.

Key Features for Custom Pouch Production

1. Specialty forming collar system: Interchangeable forming collars allow manufacturers to produce multiple custom pouch shapes on the same machine, maximizing equipment utilization across product lines.
2. High automation with format flexibility: The PLC system stores parameters for different pouch shapes and fill volumes, enabling quick changeover between product runs through recipe recall rather than mechanical reconfiguration.
3. Precise dosing for premium products: The volumetric or piston filling system delivers consistent fill accuracy essential for premium cosmetics, pharmaceuticals, and specialty food products where overfill translates to significant cost.
4. Superior seal integrity: Temperature-controlled sealing jaws accommodate various film structures and thicknesses, ensuring hermetic seals that protect product freshness and prevent leakage.
5. Material versatility: Compatible with a wide range of composite films including paper-plastic, plastic-plastic, and aluminum-plastic laminates, giving brands freedom in packaging material selection.
6. Hygienic construction: Stainless steel product contact surfaces and accessible cleaning points support GMP-oriented production requirements for pharmaceutical and food applications.
7. Intelligent control and monitoring: Real-time production diagnostics, batch counting, and fault alarms help maintain consistent quality during extended production runs.

Applications Where Custom Shapes Create Value

Cosmetics brands use custom-shaped pouches for single-use serum samples, face mask sachets, and travel-size product packaging that reinforces brand identity. Food companies package premium sauces, dressings, and condiments in distinctive shapes that differentiate products on crowded shelves. Pharmaceutical manufacturers use shaped pouches for effervescent tablet packaging and single-dose liquid medications. Promotional sampling campaigns across all industries benefit from custom pouch shapes that attract consumer attention and improve trial rates. The machine's ability to produce consistent, professionally finished custom shapes at production speeds makes it practical for both retail product lines and promotional campaigns.

Quality Standards and Compliance

The machine is constructed from SUS304 stainless steel with optional SUS316 product contact parts for corrosive product applications. Construction follows GMP-oriented design principles and supports CE certification for international markets. The PLC control system incorporates imported components for reliable operation in continuous production environments.

After-Sales Support

Comprehensive support includes operation manuals, installation videos, online technical assistance, and remote troubleshooting. Lifetime technical support is provided, and overseas engineer installation can be arranged. Custom forming collar design and manufacturing services are available for brands requiring proprietary pouch shapes. Standard delivery time is 7 to 15 working days.
