The single-dose pods have become very popular to the extent that there has been a large growth in the detergent industry. They are compact pre-measured packets, which are safe and convenient to the consumers and thus are a rapidly increasing product within the cleaning segment. However, there is a quality detergent pod-making machine behind each perfect pod. The question that always comes to mind for manufacturers is: Will you adopt a linear or rotary machine?
This guide will comprehensively detail the differences between a linear and a rotary detergent pod-making machine, how they compare, and the various advantages/ disadvantages of each, and how to select the best to suit your requirements.
The production path of the linear detergent pods making machines usually follows a simple production path. Pods are filled, sealed, and cut consecutively in a straight path through these machines. They are modular, and manufacturers normally affiliate stations that perform certain functions like film unwinding, filling liquids, and sealing.
Key Features:
Rotary detergent pod machine runs on a circular motion; the processes of this machine happen on a rotating platform. This rotary is smaller and is designed to manufacture high volumes at high speeds. The above activities are done around a revolving turret, thus making the process smooth and quick.
Key Features:
Let’s discuss each step properly.
In a linear detergent pod machine, it commences by feeding a roll of water-soluble PVA film into the production line. The film is rolled off in a smooth way so that straightening and tension can be done easily, and this process forms the base of the formation of pods in later stages.
When the film is in position, it travels to the molding area where heat and pressure are used to thermoform the film through the exact cavity shapes. Such pockets are expected to contain the detergent formula, l, and they are customized based on the size and shape of the pods.
The formed cavities are filled at a filling station where a measured quantity of liquid or gel detergents is filled. This allows delivery of each pod with an accurate dose, which keeps the product consistent, reduces wastage, and falls within the boundaries of quality control.
This is then filled, and a second layer of PVA film is adhered on top of the filled cavities. This layer is then heat and pressure sealed to the base film to sandwich the detergent to form a leak-proof, tamper-proof pod.
The last process involves cutting the enclosed film with several pods into sizeable units. Such pods will then be automatically transferred to the output section, where they get collected, sorted, and transferred to packaging stations.
In linear machines, all operations are placed with sequential steps according to straight-line movement, one after another, in the horizontal direction. These well-sorted-outakes outcomes make it easy to maintain and provide the option of expanding or adjusting the production line.
So, here is the process for Rotary Detergent Pod Making Machines;
In the rotary detergent pod machines, the operation is initiated by laying the PVA film on a series of rotating dies around a central turret. The film will be fitted in place with a lot of accuracy so that it fits into every cavity of the die as the system rotates.
The rotating dies are then conveyed into a thermo-forming area, where the film is heated, nd under vacuum pressures is forced into pod shapes. In this rotary molding, the continuous motion is possible, and there is consistency in shell formation as well as high precision.
Cavity packing is done by filling the formed cavities with the detergent solution through high-speed dispensing heads as the turret rotates. Several holes can be filled at once, which greatly raises the productivity of production without compromising precision.
After filling, the pods are covered with a top layer of PVA film and sealed. The sealing station is coordinated with the turret and makes air-tight seals. The film is then chopped into pods, which are ready to be sent out.
The whole rotary process works according to circular motion enabled by the turret. This layout optimizes production and minimizes machine footprint and opens up opportunities to work with high manufacturing throughput and minimum downtime.

The following are the benefits of Rotary Detergent Pod Machine;
So, the rotary detergent pod offers the following challenges;
One that suits startups or small-time manufacturing
The machines are used to manufacture high-level, high production velocities.
The two machines are used in the production of:
Linear machines are typically applied in pilot-scale manufacture, R&D, or new market development, whereas rotary machines prevail in consumer mass manufacture.
Although each of the two types of machines has its purpose of use, it is necessary to turn to industry experts when deciding what kind of machine to buy. Such factors as the pod size, film type, the liquid viscosity, the temperature during sealing, and the length of production shift examination influence.
The collaboration with a proven equipment provider can assist you both in considering all these parameters in their entirety and in aligning you with the most successful technology.

1. Which works best with start-up detergent companies?
Start-ups are more accommodated by linear detergent pod machines as they are cheaper to set up and offer more options.
2. What is the speed of rotary machines in making pods?
Rotary machines such as the POLYVA TD-350 are capable of manufacturing thousands of pods per hour and, as such, are suitable to support high-demand operations.
3. Is it possible to alternate sizes of different pods in a single machine?
Yes. With linear machines, it is easier to switch between sizes and formats, and with rotary it may need downtime to switch.
4. What type of film is in these machines?
Both types of machines are compatible with PVA (polyvinyl alcohol) film, which is water resistant and environmentally friendly.
5. Is support provided after the purchase is done?
There are brands such as POLYVA that provide full cost post-sales services of training, repair, and troubleshooting.
6. What is the machine set time?
