Frequently asked
Wet-wipes line questions
What products is the LU-WP550A intended for?
The published applications include baby wipes, flushable toilet tissues, car-cleaning wipes and industrial wet tissues. Final liquid, tissue and film compatibility must be reviewed for each product.
What output can the wet-wipes line achieve?
The published machine data states 30–80 packs per minute. Wipe count, folded dimensions, liquid dosing, pack length, sealing behaviour and downstream handling affect the sustainable rate.
Which films are listed for the machine?
The published machine data names PE, OPP, PET-paper film and aluminised or composite structures. Your packaging-film supplier should confirm barrier, sealant and migration requirements for the intended wipe formulation.
Does the machine specification need product trials?
Trials or documented validation are strongly advisable because tissue behaviour, lotion loading, pack barrier and seal contamination can materially affect production.
Process variables
Specify the wipe, liquid and pack as one system
The published 30–80 packs/min range is meaningful only when the tissue, fold, wipe count, lotion loading, film and finished-pack dimensions are defined together. A change to one input can alter stack height, seal cleanliness, pack tension and sustainable output.
Tissue and fold behaviour
Record substrate type, basis weight, fibre direction where relevant, unfolded dimensions, fold pattern and dry-stack stability. Variability at the folding stage can move directly into pack height and end-seal presentation.
Lotion and dosing
Provide the formulation or handling information required for material compatibility, the target dose, acceptable dose tolerance and the time between dosing and sealing. Excess surface liquid can affect web control and seal cleanliness.
Barrier and moisture retention
The film structure, sealant and closure concept must support the required storage period and pack use. Barrier performance should be assessed using the complete pack, not inferred from a generic film family.
Pack dimensions and wipe count
Confirm the wipe count, folded stack dimensions and finished pack length, width and height. The published 12 mm package-height value requires written confirmation for the actual format.
Hygiene and cleaning
Define product-contact materials, cleaning agents, cleaning frequency, access, drainage or containment needs and the production-environment requirements that apply to the project.
Labels, lids and coding
State whether the pack needs a reseal label or lid, batch or date coding, print registration and inspection. The position and application sequence should be included in the line layout and controls scope.
Trial criteria
What a wet-wipes line trial should prove
Use representative tissue, liquid and film, then record the results against the approved finished pack and an agreed production run.
| Area | Trial input | Check during the run |
|---|---|---|
| Tissue conversion | Production substrate, full dimensional range, fold pattern and wipe count. | Fold repeatability, edge alignment, stack stability and absence of tearing or uncontrolled stretching. |
| Liquid application | Representative lotion, target dose, temperature and any mixing or recirculation requirements. | Dose consistency, wet-out, drips, contamination control and material compatibility. |
| Film and seals | Production film construction, reel data, sealant side, print repeat and closure components. | Tracking, seal continuity, code and artwork position, pack leaks and trapped liquid in the seal area. |
| Finished pack | Approved pack dimensions, appearance, opening and reseal requirement. | Pack height, squareness, wipe placement, opening function and presentation after handling. |
| Sustained output | Required good packs per minute and timed run duration. | Good output, reject causes, stops, recovery and the effect of replenishing tissue, liquid and film. |
| Cleaning and changeover | Defined cleaning method and format-change sequence. | Access, retained liquid, change parts, recorded settings and safe return to production. |
Project boundary
Agree every interface around the wet-wipes line
The quotation should state what supplies tissue and liquid, where film and labels are loaded, how finished packs are inspected and how rejected or stopped product is handled.
Incoming materials
Define tissue roll or sheet presentation, liquid supply, filtration or mixing responsibility, film reel handling and label or lid replenishment.
Utilities and environment
Confirm electrical supply, compressed air where required, liquid services, ambient conditions, access and any hygiene zoning that affects the machine layout.
Finished-pack handling
Plan discharge conveying, code verification, checkweighing, leak or vision inspection, accumulation and case packing without damaging soft packs.
Trial questions
Materials, lotion and pack checks
What trial materials are needed for a wet-wipes line?
Provide representative production tissue, the intended lotion or an agreed safe trial equivalent, production film, any reseal label or lid, approved pack samples and enough material for setup, adjustment and a sustained run.
How does lotion loading affect pack trials?
Lotion changes the weight, compression, surface condition and height of the folded wipe stack. It can also reach the seal area or affect material handling, so dose and wet-out time must be included when pack dimensions and sealing are tested.
What should be checked during a wet-wipes pack trial?
Check fold consistency, dose, stack position, pack dimensions, artwork and code position, seal continuity, leakage, opening and reseal function, appearance after handling, good output and recovery after planned stops.
Process release
Approve the wet-wipes packing process in controlled stages
A finished pack can look acceptable while variation is building in the tissue fold, liquid dose or seal area. Release the LU-WP550A process from incoming materials through conversion, wetting, wrapping and downstream handling, using the same defined materials at each stage.
| Stage | What to establish | What to record |
|---|---|---|
| Dry tissue conversion | Substrate runs without uncontrolled stretch, tearing or fold drift across the intended wipe range. | Material identification, roll or sheet presentation, fold settings, cut dimensions and dry-stack samples. |
| Liquid application | The agreed formulation or safe trial equivalent is delivered under representative handling conditions. | Recipe reference, target dose and tolerance, supply condition, replenishment method, wet-out time and observed drips or carryover. |
| Stack presentation | Folded and wetted wipes remain within the pack envelope and reach the sealing section consistently. | Wipe count, stack dimensions, position, compression and the difficult high and low conditions tested. |
| Film forming and seals | Production film tracks and seals while liquid and tissue remain outside the sealing area. | Film and reel reference, registration settings, seal parameters, pack dimensions, appearance and the customer’s agreed integrity checks. |
| Stops and replenishment | The line handles planned stops, tissue or film changes and liquid replenishment without uncontrolled product disposition. | Stop condition, retained material, restart checks, first accepted pack and any material removed before release. |
| Changeover and cleaning | The agreed format and cleaning sequence can be completed with access to the areas that require attention. | Change parts, settings, tools, cleaning method, release checks and safe return to the approved recipe. |
| Finished-pack handling | Soft packs remain acceptable through coding, inspection, accumulation and case packing. | Pack samples before and after downstream handling, reject results and any agreed storage or moisture-retention assessment. |
Control material changes
Keep tissue, lotion and film changes linked to the approved pack
Wet-wipes performance is a combined result. A material change that appears small can alter fold height, compression, web handling, seal contamination or moisture retention, so the machine recipe should identify the material versions used to establish it.
Incoming material identity
Record tissue or substrate grade, relevant dimensions, lotion formulation reference, film construction, sealant side, reel data and any reseal label or lid. Use supplier data and batch references available to the project.
Recipe and version control
Link fold, dose, pack length, registration, sealing and downstream settings to the approved material combination. Mark assumptions clearly when a final production material has not yet been supplied.
First-off and retained evidence
Keep approved samples or photographs and the results required by the customer’s pack specification. Repeat the defined checks after a changeover, material substitution or significant stop.
Confirm the published pack-height figure for the real format
The listed machine data gives a 12 mm package height. The workable height range must be confirmed in writing against wipe count, folded stack, lotion loading, film and finished-pack requirement before the format is approved.
Why is a dry tissue run not enough to approve a wet-wipes pack?
Liquid changes stack weight, compression, surface condition and handling. It can also reach the film or seal area. The final trial therefore needs the intended lotion or an agreed safe equivalent under representative dosing and wet-out conditions.
What should be recorded when the lotion changes?
Record the formulation or version reference available to the project, target dose and tolerance, temperature or supply condition where relevant, wet-out time, contact-material review, cleaning implications and the pack checks that must be repeated.
How should wet-wipes pack height be confirmed?
Measure the folded and wetted stack across the normal wipe-count and dose range, then trial the production film and required closure format. Confirm the acceptable finished height and machine range in writing rather than relying only on the published 12 mm value.
What should be checked after a long or planned stop?
Follow the agreed product-disposition and cleaning method, then check tissue presentation, dose, film tracking, seal cleanliness, pack dimensions, code or label position and the first accepted packs before routine production resumes.
Prepare the complete wet-wipes project
Prove materials, site interfaces and routine controls beyond the base line
A wet-wipes project combines tissue conversion, liquid application and flexible-pack sealing. The acceptance plan should therefore connect incoming materials, hygiene and cleaning tasks, line utilities, retained pack evidence and the controls used after a product or supplier change.
Trials and acceptance
Use representative dry and wetted tissue, lotion and production film to define good-pack and process evidence.
