PE-Coated Paper That Is Ready for Your Converting Line
PetiPaper supplies single- and double-side PE-coated paper rolls and sheets for overseas printing houses, slitting operations, die-cutters, and food-packaging converters. We help define the conversion-critical details that influence print yield, machine stability, and finished-packaging performance.

Conversion Starts With the Surface
Confirm the print side, coating configuration, and intended processing route before sampling.
Print & Adhesion Alignment
Surface treatment and ink performance must be evaluated with your ink system, press settings, drying conditions, and artwork coverage.
Roll Geometry & Machine Fit
Width, diameter, core, edge condition, splices, and winding requirements should match your unwind, slit, print, and die-cut equipment.
Conversion-Readiness Framework
The Details That Protect Your Converting Yield
A paper roll is not conversion-ready simply because its GSM and PE weight are stated. The specifications below should be reviewed together, then confirmed through a production-representative sample on your actual equipment.
Dyne Level & Surface Energy
Corona treatment supports ink wetting and adhesion on the designated printing surface. The required dyne range depends on ink chemistry, press speed, drying method, storage time, and print coverage.
Confirm: print side, target dyne level, test method, and acceptable variation at delivery.
Flatness & Print Adhesion
Flatness, curl direction, surface uniformity, and PE adhesion can affect register, ink laydown, drying, die-cut accuracy, and downstream forming. These conditions are application-specific rather than universal.
Confirm: printing process, ink system, drying conditions, curl limits, and adhesion test criteria.
Width Tolerance & Roll Build
Usable roll width, outside diameter, core inner diameter, and winding direction must suit your unwind stands, slitting knives, printing press, and material-handling limits.
Confirm: nominal width, tolerance, maximum OD, core specification, roll weight, and winding direction.
Roll Edges & Slit Quality
Clean, protected roll edges help prevent telescoping, edge crush, dust generation, and feeding interruption. Edge expectations should be defined according to your machine sensitivity and handling route.
Confirm: edge condition, permitted damage, slit quality, wrap protection, and pallet handling requirements.
Splices & Roll Continuity
Splices can affect high-speed printing, continuous slitting, and automated converting. Whether splices are acceptable, how they are marked, and the maximum number per roll should be agreed in advance.
Confirm: splice allowance, marking method, splice construction, and maximum splice count per roll.
Tension Stability & Winding
Stable winding supports consistent web handling and reduces the risk of wrinkles, tracking issues, and tension variation during high-speed conversion. Requirements depend on roll size and line configuration.
Confirm: unwind direction, tension sensitivity, winding hardness, roll runout limits, and operating speed.
Specification Review
Build a Specification Your Line Can Run
Use this checklist to start a technical discussion. Values are not default guarantees and must be finalized against the buyer's actual material route, equipment, processing parameters, and quality acceptance criteria.
Conversion Specification Checklist
Share available values with your inquiry. Our team will review technical feasibility before quoting.
| Specification Area | Information to Provide | Why It Matters on Your Line |
|---|---|---|
| Printing surface | Print side, ink type, printing method, drying conditions, artwork coverage, required dyne range. | Supports ink wetting, adhesion, visual consistency, and print-process compatibility. |
| Paper & PE construction | Base paper type, total GSM, PE weight, 1S or 2S coating, food-contact or certification needs. | Influences stiffness, barrier performance, die-cutting behavior, forming, and finished use. |
| Flatness & curl | Permitted curl direction and level, sheet or web flatness expectations, operating environment. | Affects feeding, register, die-cut accuracy, stacking, and high-speed web handling. |
| Width & dimensions | Nominal width, acceptable width tolerance, sheet dimensions where applicable, trim requirements. | Ensures fit with unwind, print width, knife layout, die layout, and material yield calculations. |
| Roll geometry | Maximum roll OD, core inner diameter, roll weight limit, winding direction, loading preference. | Prevents incompatibility with shafts, chucks, lift equipment, unwind stands, and storage racks. |
| Edges, splices & tension | Roll-edge standard, splice allowance and marking, tension sensitivity, required winding condition. | Supports continuous running, reduces web breaks, and protects productivity during slitting and converting. |
| Packing & destination | Destination port, container type, humidity risk, pallet standard, edge protection, labeling requirements. | Helps protect rolls from moisture, deformation, impact damage, and identification errors in transit. |
Practical note: If you do not have all values yet, send your machine model, current material sample, finished-product application, and key production concerns. We can use these as a starting point for the sample discussion.
From Sample to Repeat Order
A Converting Workflow Built Around Your Actual Conditions
The goal is not to apply generic values. The goal is to lock a repeatable material specification that performs on your production equipment and is traceable through shipment and repeat supply.
- 1
Share Your Conversion Route
Tell us whether you print, slit, die-cut, form, laminate, or distribute the material. Include the end product, machine type, operating speed, and any current material issues.
- 2
Define the Producible Technical Range
PetiPaper reviews base paper, PE configuration, dimensions, roll build, packing, documentation, and feasibility against the information provided.
- 3
Test a Production-Representative Sample
Run the sample through your actual printing, slitting, die-cutting, heat-sealing, forming, or packing process. Record operating conditions and observations.
- 4
Lock the Approved Specification
Finalize tolerances, sample reference, quality criteria, splice policy, roll packing, inspection expectations, and batch-identification requirements before trial order confirmation.
- 5
Control, Document & Repeat
Mass production is controlled against the approved reference. Batch records, inspection documentation, moisture-protective packing, and loading records support repeat ordering and claim traceability.
Technical Inquiry
Send Your Converting Requirement
Request a sample or share your existing specification. The more we know about your press, slitter, die-cutting process, and finished application, the more accurately we can prepare the technical discussion.
Best for sample requests: include your intended application, material construction, required width, roll format, and destination.
Technical confirmation first: final performance requirements are confirmed through feasibility review and testing on your actual converting conditions.
