How Do Water-Soluble Pod Packaging Machines Work?

The water-soluble pods used in detergents, disinfectants, and household cleaning solutions have seen an exponential rise in demand globally over the last decade. When it comes to choosing the appropriate water-soluble pod packaging machine, the choice is not only an investment as it is a tool of the manufacturing/ procurement manager of daily chemical plants, OEM/ODM factory, but a gateway to throughput quality of the product, cost-efficient production, and savings.

Polyva advanced with the making machine solutions of detergent pod: Polyva has built a set of superior pod packaging equipment that should not only be fast and precise but also meet the strict requirements of GMP/FDA. However, do these machines work?

The article will describe the mechanism within the machine - from feeding film to cutting pods- describing each outcome and process within the machine. We will also plot the 2-second cycle time of the machine and the production capacity up to 600-800 pcs/min. Lastly, we will mention unique technologies used in the machines of the company Polyva, which make its machines leaders in this sphere.

What is the Water-Soluble Pod Packaging Machine?

It is a special and particular automated machine that is used to produce the pods (capsules) that are fully dissolved in the liquid. These pods can be constructed out of PVA (polyvinyl alcohol) film, which is biodegradable and also water-soluble. The machine-stuff loaded the pods with liquid, powder, or gel-formulas and most regularly detergents, cleaning agents, disinfectants, agrochemicals, or personal attention products and seals the pods in strict unit doses.

Major Characteristics of a Water-Soluble Pod Package Machine

Water pod packaging machines are intended to be efficient, precise, and sustainable. The following are the unique benefits that have made them a favourite detergent, cleaning, and personal care product:

1. Uses PVA film

The brother works with polyvinyl alcohol (PVA) film, which is a water-soluble compound that does not leave any residue. This renders it consumer safe and ecological.

2. Automates production

Film feeding is all automated through the rest of the pod, cutting to the ease of an endless loop. This minimizes human work, enhances productivity, and provides uniformity in all batches.

3. Precision dosing

High precision of metering systems injects precise quantities of liquid/powder into any given pod. This ensures uniform weight and performance of the products and reduces wastage due to overfilling or underfilling.

4. Sealed for safety

There are no leakages, spilled or contaminated substances in all the pods because they are hermetically sealed at a controlled pressure and temperature.

5. Eco-friendly nature

As the PVA film is completely soluble in water, no waste is left as packaging. This renders pods as a viable alternative to conventional packaging (plastic or sachet).

How to use a Water-Soluble Pod Packaging Machine  - Step-by-Step Process

A water-soluble pod packaging machine is rather a production line impeccably synchronized, each of the stages expands upon the last one, and the micrometer is the end result. During the first film feeding to final cutting, one step after another ensures the pods are strong, uniform, and are packaged. The process entails the following:

1. Film Feeding System

The PVA(polyvinyl alcohol) roll (film) is used in the outer cover of the pod, and it forms the starting element of the process. This film is unwound and passed through rollers in the machine with five trips applied to ensure that the film is well aligned. The Dual Servo Pulling system also allows Polyva to maintain the constant controlled tension on the film to ensure that it does not wrinkle, slip, or stretch.

Results:

• Accuracy in film alignment±+ -0.5 mm is needed to keep film alignment later.
• Under 1% wasted movies, and production is low.
• The positioning of smooth and wrinkle-free film, with the consistent shapes of the pods.

This is the stage of making a perfect canvas before getting to painting- any form of misalignment would lead to errors in the future.

2. Molding Chamber

After positioning a film, it enters the molding chamber where it is forced into pod-shaped spaces under low vacuum pressure. PVA film is prone to cracking when too dry and to stickiness when too moist, so Polyva keeps its chamber conditions high 40-45% relative humidity, 25+-2degC.

Results:

• The motion picture remains non-brittle and flexible without any cracks or tears.
• Here, cavities are of regular depth and thickness.
• The cavity is flawless and solid, waiting to be filled with liquids.

This phase resembles moulding dough in the same shape under well-regulated circumstances in order to ensure uniformity.

3. Liquid Feeding and Metering

After preparation of the cavities, filling is the second action. Each cavity is sprayed with a high-precision metering system that sprays detergent, disinfectant, or any other chemical solution. Liquid volume is adjustable based on the size of the pod: 50 ml, 80 ml, or 100 ml of liquid. Polyva machines also have one-touch format changeover, which enables switching between product variants of different sizes very fast, just 15 minutes - a significant benefit to OEM/ODM vendors who have many product lines.

Results:

• Identical dosing on every pod.
• There is no risk of overfills or underfills causing leakage and customer complaints.
• Distinctiveness to manufacture various SKUs within a consigned line.

You can think of a cook filling the same amount of food in a hundred different cups--this way, he makes sure that each pod is the same.

4. Sealing Process

Once filled, a second and careful layer of PVA film is laid to cover the filled cavities. The Horizontal Sealing system developed by Polyva uses a combination of regulable pressure and heat to incorporate the two film layers into airtight pods.

The machine operates an oil-free vacuum, which assures product safety, and the process as a whole meets the GMP and FDA standards of hygiene.

Results:

• The pods are air-tight, making it impossible for them to leak.
• The liquid is stored in strong, consistent seals unless the pod dissolves in water.
• Contamination-free Hygienic production.

It is the "lock and seal" moment, such as fitting a lid slightly tight on a container to safeguard the contents.

5. Cutting and Final Shaping

Lastly, the sheet of pods slides into the cutting machine. The blades are sharp enough to cut the extraneous film and separate the pods into a unit or a multi-pod strip piece based on the packaging requirements.

Results:

• Unfortunately, no jagged cuts on the pod edges.
• Less than 1 percent of movie scraps is cut down on waste.
• The pods are of the same size and look, and are prepared to be finally packaged.

This step involves baking cookies into dough- each pod is crisp in shape, attractive to the customer.

Applications of Water-Soluble Pod Packaging Machines

These machines are applicable across several industries, and dosing and handling have been made more convenient, safe, and sustainable.

• Laundry detergent pods- Ready-to-use amounts that allow convenient home or commercial laundry.
• Dishwasher pods - No-mess dishwasher cleaning solution.
• Surface cleaning pods - single-use cleaners that are prepared by integrating them into water.
• Agrochemical dose pods - An improved method for handling pesticides and fertilizers with limited chances of exposure.
• Personal care / cosmetic samples - Hygienic, single-use doses of shampoos, lotions, or gels.

Importance of this to Process Engineers and Purchasing Managers

Precision and consistency mean to a process engineer fewer machine stoppages, reduced maintenance, and a steady production environment. To a purchasing manager, low scrap rates, quick format alternative, and high throughput translate right into ROI. Polyvinyl owners find it more convenient since OEM/ODM businesses enjoy considerable flexibility and can accommodate a wide range of customers. They can have a minimum level of downtime.
