Wet toilet tissue is becoming an increasingly popular hygiene product for toilet use. Unlike traditional wet wipes, it is designed with better dispersibility and is commonly made from flushable nonwoven materials. For manufacturers, producing wet toilet tissue requires more than simply adding liquid to folded wipes. The folding, perforation, stacking, wetting and packaging processes all need to work together to achieve a consistent and convenient finished product.
What Makes Perforated Pull-Out Wet Toilet Tissue Different?
One of the main features of this type of wet toilet tissue is its perforated pull-out design.
The sheets are connected through a controlled perforation structure rather than being completely separated. When the user pulls out one sheet, a small corner of the next sheet is brought out at the same time. The used sheet can then be easily torn off, leaving the next sheet ready for use.
This design makes continuous sheet dispensing much easier and provides a convenient one-sheet-at-a-time experience. It is different from traditional wet wipes, which are commonly stacked as separate individual sheets without a continuous perforated connection.
For manufacturers, this means that the folding and perforation process is particularly important. The perforation must be accurate enough to provide a reliable connection between sheets while still allowing the user to tear the sheet off easily.
How Does a Wet Toilet Tissue Machine Work?
A complete wet toilet tissue production line normally follows this process:
Unwinding → Folding & Perforation → Counting & Stacking → Cutting → Liquid Application → Packaging → Lid Attaching
The raw nonwoven material is first automatically unwound with controlled tension. It is then folded and perforated into the required sheet format. The sheets are counted and separated into stacks according to the preset quantity before being cut to length.
After stacking and slitting, the dry tissue is transferred to the liquid application system. Unlike processes that pre-wet the continuous material web, the liquid is applied to the finished folded stacks through a multi-side spray system. This allows the liquid to penetrate the stack evenly while keeping the folding and perforation process dry.
The wetted stacks are then automatically inspected, packaged, and transferred to the lid attaching machine to complete the finished product.
Key Features of a Modern Wet Toilet Tissue Machine
Precise Folding and Perforation
The folding unit uses servo-controlled folding technology to maintain consistent sheet dimensions and accurate perforation positioning. Automatic counting and separation ensure that each stack contains the required number of sheets.
For perforated pull-out products, stable perforation is especially important because the connection between sheets directly affects the user’s dispensing experience.
Automatic Counting and Stacking
In a fully automatic production line, a servo-driven control system is used for precise sheet counting. The system calculates the rotation of the folding rollers to determine the exact number of sheets formed during each cycle. Based on the preset stack quantity, the machine automatically performs accurate separation of each stack before transferring it to the cutting unit.
Uniform Liquid Application
After folding, perforation, stacking and cutting, the dry stacks enter the liquid application system. The system uses multi-side spray nozzles and metering pumps for controlled liquid dosing.
The liquid amount can be adjusted according to the required wet-to-dry ratio, while the spray configuration helps the liquid penetrate the stack evenly. This is important for maintaining consistent moisture throughout the finished product.
High Level of Automation
A complete line can integrate automatic material unwinding, folding, perforation, counting, stacking, liquid application, packaging, metal detection and checkweighing, vision inspection and automatic lid attaching.
With servo motors, PLC control and touchscreen operation, the production line can run continuously with reduced manual intervention.
Flexible Configuration
Not every manufacturer requires the same product specification or level of automation. The production line can be configured according to product dimensions, sheets per pack, production capacity, liquid dosage and packaging requirements.
Optional equipment such as a metal detector and checkweigher, vision inspection system and automatic lid applicator can also be added according to the customer’s requirements.
How to Choose the Right Wet Toilet Tissue Machine?
Before selecting a machine, manufacturers should first define the product they intend to produce. Important factors include the target production capacity, finished product dimensions, sheets per pack, packaging format and required liquid dosage.
The type and width of the raw material should also be considered when selecting the unwinding and folding system. For perforated pull-out wet toilet tissue, particular attention should be paid to the folding method, perforation accuracy and stack separation method.
For a fully automated production line, manufacturers should also consider downstream equipment. A packaging machine, metal detection and checkweighing system, vision inspection and automatic lid attaching machine can be integrated to create a complete production process from raw material to finished product.
Conclusion
A modern wet toilet tissue machine is designed not only to produce wet wipes, but to create a specific perforated pull-out product with a convenient dispensing experience. Accurate folding and perforation, reliable counting and stacking, uniform liquid application and stable packaging are all essential to the final product.
For manufacturers entering the flushable wet toilet tissue market, choosing the right production line is therefore closely related to both product quality and production efficiency. A properly configured line can provide a stable and flexible solution for producing different specifications of perforated pull-out wet toilet tissue.
