Automated Liquid Packaging Solutions

Revolutionizing Safe Drinking Water Distribution Globally

In many developing regions across Africa, Southeast Asia, and Latin America, sachet water (commonly known as water pouches) serves as the primary source of clean, affordable drinking water. Packaging water in flexible plastic film pouches requires specialized machinery that guarantees absolute hygiene, high sealing integrity, and low operational costs. As a premier China water pouch filling machine manufacturer, Ludyway Packing Machine provides state-of-the-art packaging systems designed to convert rolls of food-grade PE film into perfectly filled, sterilized, and sealed water sachets.

Our machinery is engineered to handle various types of non-carbonated liquids, including mineral water, pure spring water, drinking water sachets, milk, juices, and liquid condiments. By utilizing advanced UV sterilization technology, our systems ensure that the water remains uncontaminated from the moment it enters the dosing system until the pouch is sealed.

Why Pouch Packaging is Dominating the Clean Water Market:

Compared to traditional PET bottles, flexible pouches reduce plastic raw material consumption by up to 70%, lower transportation costs due to their lightweight properties, and require significantly less storage space. This makes water pouches the most economically viable solution for delivering clean hydration to urban and rural populations alike.

How It Works

The Automated Water Pouch Packaging Process

Understanding the exact step-by-step process of water pouch packaging ensures that operators can manage production efficiently while maintaining high standards of sanitary control. Our vertical form-fill-seal machines execute the entire cycle automatically:

Film Feeding & Tension Control

A roll of food-grade LDPE film is mounted on the machine’s back reel. Dynamic tension rollers pull the film smoothly to prevent stretching or tearing, ensuring consistent pouch dimensions.

Inline UV Film Sterilization

Before the film enters the forming tube, it passes through a high-intensity UV sterilizer chamber. This step kills 99.9% of surface bacteria and pathogens without chemical residue.

Pouch Forming & Vertical Sealing

The flat film is guided over a metal forming collar, shaping it into a hollow cylinder. A vertical thermal sealing bar seals the overlapping edges of the film to form a continuous tube.

Precise Volumetric Liquid Filling

Filtered pure water is injected into the tube through a hygienic stainless steel filling pipe. A volumetric piston pump or gravity-fed valve controls the liquid volume with high accuracy.

Horizontal Sealing & Safe Cutting

A pneumatic horizontal sealing jaw seals the top of the filled sachet (which simultaneously becomes the bottom of the next sachet). An integrated blade cuts the sealed pouch, which then drops onto a discharge conveyor.

Answers to Your Queries

Frequently Asked Questions (FAQ)

What types of film are suitable for water pouch filling machines?

Single-layer food-grade LDPE (Low-Density Polyethylene) film is the most commonly used material for standard water sachets. For higher barrier protection or premium liquids, laminated films such as PET/PE or PET/AL/PE can also be used depending on your machine configuration.

How is hygiene maintained inside the filling machine?

Hygiene is ensured through multiple built-in systems: all contact parts are made of sanitary SUS304 or SUS316 stainless steel; an inline UV sterilizer sanitizes the packaging film; and the fluid pathway is fully enclosed, designed for easy sanitization and Clean-in-Place (CIP) integration.

Can one machine pack different pouch sizes (e.g., 250ml and 500ml)?

Yes, the filling volume can be adjusted easily via the PLC touchscreen control. However, if the pouch width changes significantly, you will need to replace the bag former tube, which is a quick-change component designed to minimize downtime.

Do you supply the auxiliary equipment like water filters and date printers?

Yes, as a turnkey solution provider, Ludyway offers complete packaging lines, including raw water treatment systems (RO filtration), UV sterilizers, coding machines (ribbon coder or inkjet), checkweighers, and collection tables.

What is the warranty and after-sales service policy for international orders?

We offer a 12-month warranty on all our packaging machinery. We provide detailed installation manuals, video guides, online video technical support, and can dispatch engineers to your facility for onsite setup and operator training upon request.
