One-Stop-Flexible-Packaging-Solutions

Wenzhou Xiaopai Electric Power Technology Co., Ltd. (XIAOPAI) supplies complete

flexible packaging lines and the materials that run on them: one contract, one specification and one technical contact, from layout drawing to warranty.

XIAOPAI is an authorized global distributor of SINSTAR flexible packaging machinery, which gives buyers three practical benefits: a proven, series-produced design rather than a one-off build; a technical file and spare-parts channel open for the life of the machine; and a line configured, installed and supported by engineers who work on these machines daily.

What we supply

Two businesses, one delivery method

XIAOPAI began in power equipment: distribution transformers, vacuum circuit breakers, switchgear and compact substations up to 230 kV and 200 MVA, shipped to more than forty countries. Flexible packaging is a second business built on the same export operation and customers: a manufacturer who buys electrical equipment for a new plant often asks months later who can equip the packaging hall next door.

What carried over is how we deliver: one contract, one specification, one technical contact and a schedule that holds. A buyer sourcing six machines from five suppliers spends the project managing the gaps between them. With XIAOPAI, we manage those gaps.

Who we work with

l A converter building a first line — one laminator and one slitter, laid out so two more stages can be added without relocating them.

l A plant replacing one stage — one machine matched to the web width, speed and core size of the existing line.

l A trader or integrator — a documented English package to hand to their own client.

A line is only as complete as the qualified sources behind each stage ofit.

XIAOPAI does not build every component in-house. Instead the company keeps an audited pool of specialist manufacturers — three to five qualified builders per equipment category. A line is assembled from that pool around the buyer's product, and XIAOPAI carries the interface:   configuration,   inspection,    installation,   commissioning,    training   and   spares afterwards.

How a builder enters the pool

Why the pool matters to the buyer

Most packaging projects fail not on the machine but on the interfaces between machines, or between the approved sample and the delivered roll.

This is the sequence we follow on every line, whether it is one laminator or a six-stage plant. Each step ends in a document the buyer approves, so a problem appears at the step that caused it.

How we work

l Line first, machine second. Start from the finished pack and work back to the machine.

l No hidden scope. Every scope sheet states what is included and what the buyer prepares.

l Documentation in English. Manuals, drawings and parameter tables, so the line runs without a translator.

The six steps

A line is specified only after the duty point in step 1 is agreed; specifying machines first is how buyers get equipment that runs well, but not on their product.

A flexible packaging plant is a chain, not a collection of machines. Film leaves the extruder,

takes its print in the flexo press, receives its barrier layer in the laminator, and is finally slit to the width the bag maker needs. The line is only as good as the weakest handover between those steps: web tension, web width, roll hardness and roll diameter all have to agree.

XIAOPAI supplies every step of that chain, which is why the models in this document are grouped by process rather than listed as a catalogue. Matching the slitter to the laminator, or the blown film die to the printer's web width, is a decision we make with you before an order exists.

Component brands, electrical schedules and commercial terms are left out of this document and supplied in the order-specific technical file.

Which line makes which pack

Where a pack falls outside this table, the line is still configured from the pack backwards. The constraint is the finished product, not the machine list.

Extrusion sets the limit for every step downstream: film that leaves the die with uneven thickness cannot be printed in register or laminated flat. The three-layer IBC line below controls this at the source — bubble cooling fixes the frost line, three extruders place the additives in the skin while the core carries strength, and the take-off is servo-synchronised.

ABC-1800 Three-Layer Co-Extrusion IBC Blown Film Line

Three extruders with internal bubble cooling, for LDPE, LLDPE, MLLDPE and HDPEfilm at 100–120 m/min.

Key advantages

l Internal bubble cooling — cooling air circulates inside the bubble as well as outside it, which raises output for a given die diameter and holds the frost line stable at speed.

l Independent layer dosing — additives sit in the skin, where they are needed, instead of being spread through the whole wall.

l Gauge held across the web — on LDPE at 0.15–0.20 mm, thickness deviation stays within ±4%, the figure that decides downstream register.

l One line, four resins — no die change between bag grades.

Technical parameters

ABC-1800 — extruder, 11 m bubble tower, traction and winding

All three presses  share  one  platform. A  central  impression  (CI)  drum  carries  the  web

through every colour without releasing it, gearless electronic shafts replace the gear train, and plate and anilox cylinders are sleeve type. Because the web stays on the drum between colours, register holds while the press speeds up or slows down — the defining property of a CI press.

Shared  by  all  models:  closed-chamber  doctor  blade,  non-stop  flying-splice  unwind  and rewind, closed-loop tension with taper control, automatic edge guide before the first unit, and PLC print inspection on the running web.

The  models  differ  in  the  job  they  are  built  for:  heavy-duty  FFS  sack  film  with  in-line embossing and folding, high colour count at  1000 mm width,  or a mid-width workhorse. Choose on print width, colour count and whether you need embossing.

The three models at a glance

CIflexo press in production — non-stop unwind, in-line corona and video web inspection

Master Series FFS Heavy-Duty Full Servo Sleeve CI Flexo Press

Four colours at 800 mm with in-line embossing and folding — a press built for heavy-duty FFS sack film, where printing, embossing and gussetfolding happen in one pass.

Key advantages

l Three processes, one pass — printing, embossing and folding run from the same servo line, so the sack leaves the press already printed and folded.

l Register that holds at speed — ±0.1 mm, and it stays within that band while the press speeds up or slows down, where gear-driven presses lose register.

l Fast changeover — a full set of plate and ceramic rollers is exchanged in about three minutes, so short FFS runs stay profitable.

l Sized for sack film — web path, tension range and folding unit are built for 700 mm heavy-duty film rather than adapted from a general-purpose press.

Technical parameters

Master Series CIflexopress — unwind,four colour decks around the CI drum, in-line embossing and folder

Master Series YTE81000 8-Colour Gearless Sleeve CI Flexo Press

Eight colours at 1000 mm with a 500 m/min mechanical speed — the model for high-colour- count work where register tolerance decides whether the job can be sold.

Key advantages

l ±0.08 mm registration — the tightest figure in the range, and the reason this press suits photographic designs and fine reverse type.

l Eight colours at 1000 mm — enough stations for extended-gamut work, spot colours and a coating without a second pass.

l Wide substrate range — paper below 65 gsm, PE, PET, BOPP and PVC run on the same press, so a converter is not tied to one film type.

l 350–450 m/min in production — the working speed, not only the mechanical ceiling, and this is what sets output per shift.

Technical parameters

Gearless sleeve plate cylinders, closed-chamber doctor blades and the enclosed webpath between decks

Master Series YTE61000 6-Colour Full Servo Gearless Sleeve CI Flexo

Press

Six colours at 1000 mm, fully servo driven — the balanced specification for general flexible packaging, where six stations cover mostfood and daily-chemical designs.

Key advantages

l Six  colours,  1000  mm  width  —  covers  the  large  majority  of  food,  detergent  and personal-care designs without paying for stations that stay idle.

l Print repeat to 1000 mm — the longest repeat in the range, which matters for large pack formats and for shrink-sleeve work.

l Flying-lap splicing — automatic on both unwind and rewind, on rolls to φ600 mm with 3 ″, 4 ″ or 6 ″ cores.

l Wide tension window — 20–300 N under servo control with floating roller and encoder feedback, from 12 µm film to heavy paper.

Technical parameters

YTE61000 or YTE81000

Choose  the  YTE61000  when  four  to  six  colours  cover  the  design,  ±0.1  mm  register  is accepted and 400 m/min meets the shift target. Choose the YTE81000 when seven or eight colours are needed, when ±0.08 mm is written into the print approval, or when the volume calls for 350–450 m/min in production.

Hot knife lamination bonds a printed sheet or web to a film using a hot-melt adhesive that is

applied, dried and activated on the machine, then cut with a heated blade. The heated knife is the distinguishing part: it seals the cut edge as it separates the sheet, so the laminate does not delaminate at the trim and the stacker receives clean, square piles.

Two formats cover the market. Sheet-fed machines take pre-cut printed sheets and deliver a finished stack — cartons, book covers, display work. Roll-to-roll machines run a printed web against a film web and rewind — packaging film and label stock. Both XPM models apply the adhesive without solvent and both use non-stick coated drying rolls, so the adhesive releases cleanly at temperature.

The two models at a glance

Hot knife laminator — automatic sheetfeeder, hot knife coating unit and stacker

Sheet-fed or roll-to-roll

XPM-1080RN Automatic Sheet-Fed Film Laminating Machine with Hot

Knife

Sheet-fed, 1080  × 1500 mm, with a double-servo hot knife and a fully automatic stacker — the model for high-volume sheet lamination where pile quality decides the next process.

Key advantages

l Throughput without an operator at the feeder — the sheet feeder runs to about 15 000 sheets per hour with non-stop pre-stacking, so the machine does not idle while a pile is reloaded.

l Overlap held to ±2 mm — the overlap is set by servo rather than by a mechanical cam, which is what keeps the pile square at high speed.

l Either cutting method, one machine — a disc cutter covers 80–500 gsm, and the hot knife takes over above 127 gsm where a cold cut would delaminate.

l Heat  that  reaches  the  adhesive  —  an  800  mm  drying  roll  with  non-stick  coating, electromagnetic  plus  oil  heating,   and  a  25  mm  machine  wall  that  holds  the  roll temperature stable.

l Hot knife that keeps its edge — double servo positioning with a blade heat-treated to 600 °C, so the cutting geometry does not deform over a production run.

l Flat sheets into the stacker — an anti-curl device and corrugated delivery straighten thin stock before it is piled, with a 1060 mm stack height and side and front tidy plates.

l Operation — 10″ colour touchscreen on a PLC and fully pneumatic laminating pressure for a uniform nip load.

Technical parameters

Disc cutter or hot knife is decided by stock and by the next process. Below 127 gsm the disc cutter is faster; above it, a cold cut leaves a delaminated edge that shows at the die cutter.

XPM-1100J Roll-to-Roll Laminating Machine with Coating Unit

Roll-to-roll at 1050 mm with a dedicated coating unit and shaftless unwinding — the model for packagingfilm and label stock, where the output is a rewound roll, not a sheet pile.

Key advantages

l Shaftless unwinding — accepts 3 ″ and 6 ″ cores and full jumbo rolls without a shaft, so loading is a single-operator task and roll changes are short.

l Adhesive goes further — the double metal-roll coating system with a rubber or metal blade handles a range of adhesives at 3–4 g/m², which is where the consumable cost of a laminating job actually sits.

l Non-stick drying roll — the 800 mm drying roll is coated so adhesive releases cleanly, and the coating also evens out the surface temperature compared with a plain chrome roll.

l Short web path — the compact threading route reduces the material lost at every start- up and job change.

l Two tensions, not one — an independent tension system for the film roll alongside the main web tension, so a light film is not pulled to the tension the laminate needs.

l Ultrasonic web guide — non-contact edge detection ahead of the coating nip,  so the adhesive line stays inside tolerance on narrow lanes.

Because the output is a roll rather than a stack, the job is judged on roll quality as well as bond strength: a roll wound too soft will telescope on the shelf, and a splice in the middle of a lane stops the bag maker. The independent film tension and the short web path are what keep both figures under control, shift after shift.

Technical parameters

Solventless lamination applies a two-component adhesive at  100%  solids  and  cures it by chemical reaction instead of by evaporating a solvent. No drying oven, so the energy a dry laminator spends heating air is never spent; no solvent residue left in the laminate to migrate into the product, which is what makes the process acceptable for food, pharmaceutical and infant-nutrition packaging; and a shorter web path, so start-up waste and floor space both fall.

The three models cover the two decisions that matter: how many layers, and how much control. WRJ i9 is the two-layer machine for a stable high-volume structure; WRJ Fi9 adds width and multi-layer capability with full recipe management; S1 is the digital platform for plants running many short work orders, where changeover is a software event.

The three models at a glance

WRJ Fi9

WRJi9

S1

Two questions separate the three models: how many layers the structure needs, and how often the plant changes work order. Width and speed are the same across the range.

Before the line is ordered: the curing room

Solventless adhesive cures by chemical reaction rather than by evaporation, so the finished roll still needs time and temperature to reach full bond strength: typically 24 hours for a common two-layer structure, longer where foil or a high-barrier layer is involved. Curing- room area and temperature control belong in the layout, not in the week after commissioning — a fast laminator with too little curing capacity still ships late.

WRJ Fi9 Solventless Laminating Machine

The high-performance model for snack bags, frozen-food film, pharmaceutical sachets and infant-nutrition bags: 1650 mm, 450 m/min,full recipe management.

Key advantages

l Five-roller coating system — mechanically precise metering across the full web width, so adhesive weight does not drift from the centre to the edge of a 1650 mm web.

l Adhesive weight measured, not assumed — closed-loop tension control combined with coating-weight measurement keeps the bond specification inside tolerance run after run.

l No drying system at all — no oven and no heating energy, which on a comparable duty typically removes around 60 000 kWh a year.

l Zero solvent residue — suitable for food, pharmaceutical and infant-nutrition structures without a residual-solvent test in the release criteria.

l Wide substrate range — BOPP, PET, PE, CPP, PA, aluminium foil and paper in the same machine, with recipe storage so a changeover is a recall, not a re-setup.

Technical parameters

Structures routinely run on this machine

WRJ i9 Two-Layer Solventless Laminating Machine

The entry and volume model: two-layer lamination, 450 m/min, and a control system simple enough that a new operator is productive within two days.

Key advantages

l Deliberately simple — a reduced control system and a clear operating sequence mean less operator intervention per shift and far less training time. Two days takes a beginner to production.

l Multi-stage  tension  control  —   combined  with  a  stable  nip  pressure   system,   so dissimilar  materials  still  laminate  flat  and  uniform  without  a  trial  run  for  every combination.

l Compact two-layer  architecture — built  specifically for two-layer  structures rather than being a multi-layer machine run below its capability: smaller footprint, lower power, faster changeover.

l Wide  material  compatibility  —  BOPP,  PET,  PE,  CPP,  VMPET,  VMCPP,  nylon, aluminium foil and paper-based substrates on one machine.

l The same width and speed as the Fi9 — 450 m/min and up to 1650 mm, so the volume decision does not force a compromise on throughput.

Typical lamination structures

PET / PE · BOPP / CPP · BOPP / PE · PET / CPP · metallised film / plastic film · aluminium foil / plastic film · paper / plastic film.

Packaging uses

Food  packaging  film   ·  daily  consumer  goods  packaging   ·  general-purpose  laminated packaging materials.

Technical parameters

For three-layer and foil-containing structures, step up to the WRJ Fi9. The i9 is built for two- layer work; it is not a multi-layer machine sold below its capability.

S1 Digital Solventless Laminating Machine

500 m/min, 1350 mm, and a digital control layer that manages up to 300 work orders — built for plants whose constraint is changeover time, not running speed.

Key advantages

l 300 work orders in memory — temperature, pressure and speed are stored per job and recalled by number, so a changeover becomes a data entry, not an adjustment sequence.

l Three-roller back-pressure design — the coating nip is supported from behind, which keeps the adhesive film uniform and reliable across the web width.

l Tungsten-carbide coated rollers — roughly five times the wear resistance of a hard- chrome roll, so the service interval is longer and coating weight stays stable as the roll ages.

l One-click coating weight entry — the operator enters the target weight and the machine sets the metering, removing the manual trial-and-error pass at the start of each job.

l Adhesive proportioned automatically — the two components are dosed and mixed by the machine, so pot life and mix ratio are not left to the operator.

l Four-level proportional protection — a staged safety architecture covering mix ratio, pressure and drive conditions, so a fault stops the machine before it reaches the web.

l Adaptive tension and taper control — a swing-arm linkage with intelligent rewind taper, and both motors braking together so coating weight stays even during deceleration.

Technical parameters

What the digital platform changes in daily operation

The slitter is where a jumbo roll becomes saleable. Two things decide whether it does that

well: web guiding, because a lane that wanders by half a millimetre is a reject at the bag maker, and tension control, because a roll wound too hard takes a set and one wound too soft telescopes  on  the  shelf.  Both  machines  control  tension  by  calculating  roll  diameter continuously rather than holding a fixed torque, and both use non-contact edge detection ahead of the knife.

Choose on material and output: the CLFQ-W1100 is the high-speed machine for film, foil and coated paper; the 1300 Type is the wider-tolerance horizontal machine for non-woven, aluminium foil and roll paper, where cut widths are fixed rather than variable.

The two models at a glance

Slitter rewinder — shaftless unwind, razor slitting station and dual-shaft rewind

Two faults, and the setting that causes them

Both models set tension from a continuously calculated roll diameter, not a fixed torque — which is what keeps a finished roll stable on the shelf.

CLFQ-W1100 Automatic High-Speed Rewinding and Slitting Machine

400 m/min mechanical speed, 1100 mm web, 30 mm minimum slit width — the model for film and foil work where narrow lanes and high output both matter.

Key advantages

l Narrow lanes at speed — slits down to 30 mm while running to 400 m/min, which is the combination that separates a production slitter from a finishing machine.

l Correction held to 0.30 mm — a U-shaped ultrasonic sensing system with a 30 mm guide rail underneath, so the lane position is corrected continuously rather than at start- up only.

l Tension calculated, not guessed — magnetic powder tension with the PLC computing roll diameter in real time, giving soft, precise control with no residual torque.

l Fast roll handling — shaftless hydraulic lifting rack with  safety chuck locking and pneumatic loading and unloading, so a 1000 kg unwind roll is a one-person operation.

l Stable at any speed — an analogue-driven correction thruster removes the hunting that digital on-off thrusters produce.

Technical parameters

The two rewind shafts run alternately: one winds while the other is unloaded, so a roll change does not stop the line.

1300 Type Horizontal Slitting Machine

A 1300 mm horizontal slitter with fixed cut widths of45, 60, 65 and 90 cm — built for non- woven, aluminiumfoil, plastic film and rollpaper in packaging-converter duty.

Key advantages

l Built for heavy, wide rolls — a φ1500 mm unwind on a 3 ″ air-inflated shaft with a 200 N·m magnetic powder brake, so full mill rolls are handled without a shaft.

l Two independent tension zones — unwind and rewind each have their own magnetic powder clutch, so the rewind tension can be set for the lane while the unwind brake holds the parent roll.

l Photoelectric edge correction —  120 mm of correction travel at ±0.5 mm, which is ample for non-woven and foil where the parent roll edge is not straight.

l Automatic stop at length — the controller stops the machine when the set length is reached and adjusts speed to the line velocity, so a roll change is a controlled event.

l Ten circular knives — supplied as a set on a chain-driven, channel-steel frame, which keeps the machine stiff and the cut clean on heavy stock.
