Printed food-wrap papers can look interchangeable on a quotation, yet a hot burger, a sauced sandwich and a tray liner expose the sheet to different grease, moisture, folds and holding times. This procurement guide brings those decisions into one commercial specification. It complements—rather than repeats—the separate articles on sheet-yield calculations, barrier testing and artwork preparation. Any worked formula explains a method, not a Lupipak stock size or performance promise; project materials, tolerances and delivery terms belong in the written quotation.
Describe the job before choosing the paper
State whether the sheet fully wraps a burger, folds around a sandwich, lines a basket or separates food inside a box. Record typical serving temperature, grease and sauce exposure, expected contact time, folding sequence and whether the pack travels in a delivery bag. If several foods use the same design, list each one and identify the most demanding condition instead of hiding them behind a generic description.
Confirm whether the paper is in direct food contact, which face carries the print and whether the printed side could touch food during folding. Natural or white shade and surface character are brand choices; grease holdout, wet integrity and workable folding are acceptance requirements. Keep appearance and function as separate lines on the approval sheet so an attractive proof cannot accidentally approve an unsuitable substrate.
Write a barrier specification, not just a GSM
Grammage is nominal mass per square metre; it does not by itself establish grease resistance, wet strength or suitability for the intended food. Ask the quotation to identify paper type, nominal GSM, shade, grease and moisture performance, food-contact documentation and expected exposure. Ahlstrom’s QSR portfolio likewise treats grease resistance, wet resistance, printability and converting as distinct performance characteristics.
If a Kit rating appears in the specification, name the test method and conditions. TAPPI T 559 is a surface-repellency method for certain treated papers and cautions that its use for film-like or non-fluorochemical barriers needs evaluation. Do not turn one laboratory number into a universal guarantee. Pair the material data with a use test that reproduces the actual food, temperature, folds and holding time.
Choose sheet or roll format around the operation
For sheets, write dimensions in an unambiguous width × length order and test the wrapping movement with the real product. A tray liner needs enough edge coverage without curling into the food, while a full wrap needs closure without layers of unused paper. Standardising one size can simplify purchasing, but only if the resulting material use and packing speed have been measured across the menu.
For rolls, confirm web width, outside diameter or length, core inside diameter, winding direction, print orientation and the limits of any dispenser or cutting equipment. Sheet quotations should state cut tolerance and count per carton; roll quotations should state net weight, splice policy and per-roll tolerance. Use the linked yield article for conversion maths, then reconcile the answer with finished-format waste and the supplier’s net-delivery definition.
Interpret the 200 kg MOQ per design and format
On 1 November 2026, Lupipak’s greaseproof-paper page lists a 200 kg minimum order. Confirm how that minimum applies to the proposed paper, size, artwork and sheet or roll presentation. Never assume that two sizes, seasonal graphics or language variants can share one minimum; print preparation and converting may make each combination a separate production item.
Translate demand into both net kilograms and usable pieces or metres. For sheets, theoretical count equals net kilograms × 1,000 divided by sheet mass in grams, where sheet mass is width in metres × length in metres × GSM. The purchase order must still define manufacturing tolerance, trim loss, permitted over- or under-delivery, whether invoicing uses net or gross weight, and how cartons and pallets are excluded.
Approve the repeat on the cut and folded pack
Review repeat-module dimensions, direction and likely logo positions on the finished sheet. The mark should remain recognisable when the wrapper folds under a burger or is partly covered in a basket. Where print-to-cut registration has a production tolerance, do not anchor a critical logo to one edge or promise an exact position without written capability confirmation; a balanced repeating pattern is often more robust.
Work on the current supplier template and specify colours, printed face, bleed, safe area, minimum line and type sizes, plus the proofing route. EuPIA guidance highlights migration through a substrate and set-off from the printed surface in a reel or stack. Print side and winding direction are therefore food-safety inputs as well as design choices. Obtain written confirmation for the intended food-contact construction and market.
Test production-relevant samples with real food
A dimensional dummy, a colour proof and a sample made from production substrate answer different questions. Label what each sample represents. Reproduce the greasiest normal product, serving temperature, sauce contact, counter hold, delivery journey and consumer opening. Inspect flat areas, folds and printed zones; folding can create a failure route that a flat laboratory specimen does not show.
Record external staining, leakage, fibre lift, tearing, ink transfer, odour or taste effects and staff wrapping time as separate outcomes. Agree dimensional and colour tolerances, sample size and defect classes before production. Keep the approved sample with product, material and artwork-revision details so a reorder refers to a controlled specification rather than an old invoice alone.
Compare cost per usable sheet or metre
Price per kilogram can conceal commercial differences. A heavier sheet provides less area per kilogram; a poor cut layout creates more trim; an under-specified barrier can drive double wrapping in the restaurant. Request separate lines for paper, prepress and any plates, cutting or rewinding, samples, cartons, pallets, freight and taxes under one identical specification. Ask which setup charges recur on a repeat order.
Include manufacturing tolerance, rejected pieces, in-store wrapping waste and storage damage when calculating usable cost. If suppliers quote different net weights or sheet counts, normalise them to 1,000 accepted sheets or 1,000 metres delivered to the same location. The commercial terms should also state the process for shortages, print defects, transport damage and material that fails the agreed acceptance test.
Make packing data part of the quotation
For sheets, request net pieces or net weight per carton, carton dimensions, gross weight, inner wrapping and pallet pattern. For rolls, obtain net roll weight, outside diameter, core, roll count and pallet height. These figures determine shelf space, safe handling, vehicle or container utilisation and freight; total kilograms alone cannot predict the number or footprint of shipping units.
Lupipak’s product page states a standard production plan of 26 business days after artwork approval. Do not assume that sampling, artwork changes, public holidays, freight or customs are included. Work backwards from the required arrival date through sample, print approval, production, quality release and dispatch, and provide the shipping method, full destination and unloading constraints at quotation stage.
The greaseproof-paper RFQ checklist
Complete the brief below before entering Lupi’s product-selection and quotation flow. Mark an unknown barrier or grammage as ‘to be confirmed by use trial’ rather than inventing a value. The main-site product page explains the technical family; current selection and commercial quotation remain with Lupi.
The final order should bind material description, finished format, presentation, print revision, net quantity, manufacturing tolerance, acceptance method and logistics scope to one reference. That makes the reorder repeat a validated service result—not merely the same graphic file.
