Today, we take a look at a typical customer case to explain why they ultimately chose Polyva again.



In early 2018, an OEM & ODM laundry capsule manufacturer in Qingyuan, Guangdong, introduced their first Polyva NZ-350 high-speed capsule packaging machine. Thanks to its outstanding stability and efficiency, the machine enabled the customer to deliver multiple batches of orders with high quality that year. By the end of 2018, to expand capacity, the customer ordered two more NZ-660 machines of the same series.

During subsequent expansion, the customer purchased lower-cost equipment from other manufacturers in an effort to reduce procurement expenses. However, operational issues quickly emerged.



Customer feedback:"Those two machines from other suppliers often had minor faults during operation, with long repair times, causing multiple orders to be delayed. Their stability was nowhere near your machines, and both production speed and first-pass yield dropped significantly, wasting a lot of raw materials. What’s worse, the level of automation was low, requiring manual oversight in many steps, which drove up labor costs and kept efficiency down. Within months, we realized that the money we saved on the purchase price was quickly offset by these hidden losses."



After carefully evaluating capacity, cost, and long-term ROI, the customer chose Polyva again in 2021, this time upgrading directly to two NZ-F660 High-Speed Powder & Liquid Mixing Capsule Packaging Machines.

Running a pod production line can be challenging, machines stop, films wrinkle, or sealing doesn't hold up as expected. If you're managing detergent, dishwashing, or pesticide pod production, you already know that a water soluble film packaging machine is the heart of your operation. But how do you get the most out of it?

This detailed guide will show you practical, easy-to-apply ways to boost efficiency beyond just increasing machine speed. From setup optimization and preventive maintenance to avoiding common errors, every section here will help you achieve smoother production, less waste, and consistent quality.



Understand the Role of the Film Itself
The water-soluble PVA film you use directly affects machine performance. Each film type has a specific dissolving temperature, thickness, and flexibility level.


Choose film wisely: Thinner films (25–35 microns) are ideal for light-duty products like laundry pods or small-dose cleaners, while thicker films (50–75 microns) suit heavy-duty chemicals.
Check compatibility: If the film and product formula don't match, it can lead to premature dissolution or poor sealing.
Store properly: PVA film is sensitive to moisture. Always keep it in a dry, temperature-controlled space before use.

When your film and machine settings are perfectly matched, production runs more smoothly and with less waste.









Increase Efficiency with a Water Soluble Film Packaging Machine
Whether you manage a small facility or a large automated line, improving the performance of your water soluble film packaging machine can significantly cut waste, reduce downtime, and boost overall productivity.

Let's explore how to achieve that while keeping your operation cost-effective and reliable.



1. Optimize Machine Settings for Your Film Type
Every PVA or water-soluble film behaves differently under heat and pressure, depending on its grade and thickness. To maximize efficiency, it's important to fine-tune your water soluble film packaging machine settings according to the film's melting point, stretchability, and sealing temperature.

If the temperature is too high, the film may wrinkle or melt unevenly; if it's too low, the sealing strength weakens and leakage occurs. Regular calibration of the forming molds and sealing units ensures consistent pod quality and reduces waste.

Testing small batches before full production also helps identify the best parameters for your chosen film type, maintaining smooth operation and high yield.



2. Maintain Stable Environmental Conditions
PVA films are highly sensitive to moisture and temperature. When the air humidity exceeds 65%, the film can absorb water, become sticky, and lose its shape. On the other hand, overly dry air can make it brittle, causing cracks or breaks during forming.

Keeping your production room's humidity under 65% RH and temperature around 20–25°C helps maintain film stability. Use dehumidifiers, ventilation fans, and air conditioners to control the environment. Evenly regulating these conditions ensures the film feeds smoothly, forms accurately, and seals tightly.

Stable surroundings not only reduce downtime but also prevent unnecessary material waste and quality inconsistencies in the final pods.



3. Schedule Preventive Maintenance
Preventive maintenance is one of the simplest yet most effective ways to keep your water soluble film packaging machine running efficiently. Instead of waiting for breakdowns, create a consistent maintenance schedule. Clean sealing jaws, molds, and film paths daily to remove detergent or chemical residue that can affect sealing strength.

Check lubrication of moving parts weekly, and inspect rollers, sensors, and heaters for proper alignment and functionality. Monthly, perform a deep inspection to identify worn-out components before they fail.

A well-maintained machine not only improves performance but also extends its lifespan and reduces unplanned stoppages, ensuring steady and cost-efficient production.



4. Train Operators on Machine Handling
Even the most advanced water soluble film packaging machine can lose efficiency if operators lack the right skills. Proper training empowers your team to identify problems early and handle them safely. Operators should understand how to load the film correctly, adjust film tension, manage temperature settings, and detect early signs of wear or blockage.

Encourage short, frequent refresher sessions to keep everyone updated on best practices. Well-trained operators can troubleshoot sealing issues, clear minor jams, and optimize machine cycles without supervision.

This reduces downtime, limits product waste, and ensures consistent pod quality, turning your team into a strong asset for production stability.









5. Use Smart Automation to Monitor Performance
Automation technology can dramatically improve productivity. Modern systems like Polyva's full-automatic PVA pods filling and packing machine are built to handle multiple processes with minimal human intervention.

These machines feature automatic film feeding, precise filling control, and accurate heat sealing, all managed through intelligent sensors. They automatically adjust temperature, sealing time, and film tension to maintain stable output. Real-time monitoring allows you to identify performance issues immediately, reducing manual errors and boosting consistency.

This automation not only improves accuracy and speed but also saves labor costs, making it ideal for factories that aim for high productivity and reliable, continuous operation.



6. Analyze Production Data for Ongoing Optimization
Collecting and analyzing production data helps you understand where improvements are needed. Modern water soluble film packaging machines can record statistics like sealing temperature, forming pressure, downtime, and energy use.

Review this data regularly to identify recurring issues, such as when film breakage often happens or when sealing problems increase under certain humidity levels. By spotting these patterns, you can take corrective action early, such as adjusting environmental controls or changing film grades.

Using data to track performance helps maintain consistency, improve production planning, and reduce waste over time. Continuous analysis is key to sustaining efficiency and keeping operations cost-effective.



7. Choose the Right Film and Machine Combination
Not all films work well with every packaging machine. Selecting the right pairing between your water soluble film packaging machine and PVA film type is essential for reliable results. For lighter loads like detergent pods or shampoo samples, use thinner films (25–35 microns).

For heavier products such as disinfectants or pesticides, thicker films (50–75 microns) perform better under pressure. The film's solubility and mechanical strength must match the filling product's chemical composition.

Choosing the correct machine-film combination ensures smooth forming, accurate sealing, and clean dissolution in water. This not only increases productivity but also improves the final user experience.









FAQ
1. Besides increasing machine speed, what other methods can truly increase daily output?
Focus on reducing idle time between batches and improving film loading speed. Preheating the machine before each shift and organizing raw materials nearby saves several minutes per cycle, adding up to a big difference daily.



2. How can I reduce downtime caused by film breakage and poor sealing?
Keep your film tension balanced and control humidity. Overly dry or wet environments weaken film strength. Also, regularly clean rollers and sealing molds, dirt or residue can cause uneven sealing or film slippage.



3. What common operating errors are inadvertently reducing my efficiency?
Using the wrong film thickness, skipping pre-shift temperature checks, or ignoring small alarms are frequent mistakes. These small issues gradually increase waste and reduce pod consistency.



4. How can I maintain peak equipment performance through preventive maintenance?
Follow a simple plan: daily cleaning, weekly checks, and monthly servicing. Preventive maintenance avoids emergency downtime, extends component life, and ensures your water soluble film packaging machine runs steadily.
