Introduction
Search for burger wrap at factory level and the phrase that keeps surfacing is "hamburger paper with waterproof film coating to prevent grease seepage". What that phrase describes is a specific construction: a paper base extrusion-coated with a thin polyethylene (PE) film, which blocks both fat and water in a way that plain greaseproof paper cannot. It is not the only construction a burger programme can use, and it is not automatically the right one. Greaseproof paper refined to KIT 12 and wax paper both wrap burgers in real QSR chains today, and a purchasing team that specifies the wrong construction pays for it in grease strike-through, soggy buns and rejected cartons rather than in the unit price.
This guide compares the three constructions a QSR burger programme actually chooses between — PE coated film paper, greaseproof paper at KIT 12, and wax paper — across grease barrier, moisture barrier, heat tolerance, print, food-contact documentation and cost position. It then converts the comparison into a specification and RFQ checklist a chain buyer can send to multiple factories and compare line by line. Chain programmes already running fried food lines can pair this guide with the greaseproof paper QSR guide, which covers KIT ratings and basket liner formats in more depth.
1. What "Waterproof Film Coating" Actually Means on a Hamburger Wrap
The word "greaseproof" is used loosely in the market; "waterproof film coating" is narrower and more literal. Three different barrier mechanisms sit behind the hamburger wraps quoted to QSR chains, and they are not interchangeable.
PE coated paper starts as a greaseproof or kraft base that runs through an extrusion coater, where a thin polyethylene film (typically a few grams per square metre) is laminated onto one or both surfaces under heat and pressure. The film is a continuous plastic barrier: it blocks oils, fats, water and water vapour, and it holds that barrier even when the paper underneath would soften with moisture. PE coated wrap is the construction buyers describe when they ask for a "waterproof film coating to prevent grease seepage", because the film stops strike-through physically rather than by fibre refining.
Greaseproof paper (KIT 12) is uncoated. Its grease resistance comes from extensive refining of the pulp, which closes the pores between fibres; a KIT 12 rating means the paper resisted a specific test dye/oil mixture through 12 test steps, the top of the common scale. Greaseproof paper is grease-resistant but not waterproof — it absorbs water and water vapour over time, which matters for held or delivered burgers where condensation forms inside the wrap.
Wax paper is a paper base with a paraffin wax coating applied to one or both sides. Wax repels water resists grease well, and it is the cheapest of the three constructions. Its limits are temperature (wax softens and can transfer above roughly 40–60 °C depending on formulation), delamination under sustained heat, and the growing number of markets and chains that prefer to move away from wax for recycling and food-contact reasons.
The practical consequence: "waterproof film coating" in an RFQ is a request for a moisture barrier as well as a grease barrier, and only PE coated construction answers both in one sheet. Buyers comparing these specifications can review our silicone-coated parchment sheets and rolls programme, where coating weight, base grammage and release values are documented per construction.
2. PE Coated vs Greaseproof (KIT 12) vs Wax Paper: Head-to-Head
The table below is the comparison a procurement team should build before requesting quotations. Values are typical ranges for QSR burger wraps; always confirm them against the supplier's own test reports for the exact grade offered.
| Criterion | PE coated film paper | Greaseproof paper (KIT 12) | Wax paper |
|---|---|---|---|
| Barrier mechanism | Extrusion-laminated PE film, continuous barrier | Fibre refining (pore closure), no film | Paraffin wax coating |
| Grease / oil barrier | Excellent; film blocks strike-through mechanically | Good; KIT 12 is the top common rating; resists but does not block all oil | Good; wax repels surface oil |
| Water / moisture barrier | Excellent; blocks liquid water and slows vapour | Poor; absorbs moisture, can soften and lose stiffness | Good when intact; wax layer can crack and lift |
| Heat tolerance | High; typical burger hold temperatures well within PE limits | High; uncoated paper tolerates oven and hold heat | Limited; wax softens and can transfer at higher temperatures |
| Print and brand finish | Printable with treated film and suitable inks; smooth, slightly plastic feel | Prints cleanly; natural paper feel preferred by craft brands | Printable; wax surface can reject ink |
| Food-contact documents | Film and ink system must be declared; FDA / LFGB scope per market | Base paper and any additives declared; commonly documented | Wax composition declared; some markets restrict applications |
| Cost position | Highest of the three | Middle | Lowest |
| Best QSR use | High-oil burgers, long hold, delivery, double-wrap programmes | Fresh-served burgers, short hold, craft positioning | Cost-driven, short-hold, single-serve applications |
Two clarifications matter when reading this table. First, "greaseproof KIT 12" is not a universal product code — KIT measures grease resistance of the sheet, not moisture behaviour, so two KIT 12 papers from different mills can still behave differently on a wet burger. Second, a PE coated sheet still needs its film and ink system documented for food contact; a film that performs perfectly on the line is worthless if the declaration does not cover the destination market. For production volumes, the same construction logic applies to our food-grade die-cut parchment rounds line, quoted per roll, sheet or die-cut format.
3. Match the Wrap to the Menu and the Hold Time
The right construction is decided by the fattiest item on the menu, the longest hold time and the moisture the package will trap — not by the cheapest quote. Four profiles cover most QSR burger programmes:
- Fresh-served classic burgers (hold under 10 minutes). Greaseproof KIT 12 is usually sufficient and gives the most natural hand-feel; moisture is not on the table long enough to soften the wrap.
- High-oil proteins (bacon, double patties, fried additions, cheese sauces). Oil keeps working after the wrap closes. PE coated construction prevents strike-through mechanically, and the printed logo survives the hold.
- Delivery and long-hold programmes (20 minutes and beyond). Condensation is the failure mode: a greaseproof-only wrap absorbs vapour from the hot burger and goes limp. PE coated film is the construction that holds both grease and moisture, which is why delivery-first chains standardise on it.
- Double-wrap and presentation programmes. Some chains wrap for barrier and re-wrap for brand. Where the outer layer carries the print, the barrier layer can be a simpler construction — but the interface still needs to be specified, or the print layer becomes the grease layer.
Whatever the profile, run the wrap against the actual menu before approving: the fattiest sandwich, the longest approved hold, and the real pack-out. A supplier's datasheet cannot replace that trial, and a wrap that passes a laboratory kit test can still fail a cheese sauce at minute fifteen.
4. Write the RFQ So Quotes Are Comparable
A quotation is only comparable to another quotation if the specification fixes the variables. For hamburger wrap programmes, the RFQ should state:
- Construction: PE coated (film weight in g/m²), greaseproof (KIT rating), or wax (wax weight) — one construction per line item.
- Base paper: grammage in g/m² with tolerance, and the test method used to verify it.
- Barrier evidence: KIT test result or the supplier's grease strike-through method, plus water absorption or vapour behaviour where moisture matters.
- Format: roll width and length, sheet size, or die-cut; interfold pattern where sheets are dispensed.
- Print: number of colours, artwork file standard, whether the print sits on the film side or the paper side of a coated sheet, and the low-odour ink requirement.
- Temperature limits: maximum continuous temperature the wrap will see on the line and in the hold cabinet.
- Food contact: destination markets, and the documents required — FDA scope for the US, LFGB / BfR-style declarations for the EU.
- Pack and logistics: pieces per inner pack, cartons per pallet, carton marking and batch coding.
Two lines deserve special attention. Print on PE film behaves differently from print on paper — the film side usually needs surface treatment and compatible inks, so "full colour logo, both sides" must be confirmed as feasible before the artwork is approved. And the temperature line must reflect the hold cabinet, not the oven: a construction that survives a warming lamp for four hours is a different product from one rated for the same duty for forty minutes. A quote-ready programme description of the printed wrap formats for chain menus is available on the burger wrapping paper page, including custom print and food-safe ink options.
5. Food-Contato Documents, PFAS and Destination Markets
Grease performance is only half of a wrap specification; the other half is the document set that lets the wrap ship into the target market. For burger programmes, three areas decide most audits:
- Declaration scope. Ask for a declaration that identifies the exact construction — base paper, coating or film, inks and any additives — and the food types and conditions of use it covers. A declaration that names only "food grade paper" cannot be matched to your SKU.
- PFAS position. Some traditional greaseproofing agents have been phased out in major markets, and chains increasingly require PFAS-free declarations. The film construction avoids the question entirely for the barrier layer, but inks and additives still need to be declared. Where a PFAS-free declaration is required, our PFAS-free baking paper programme documents the transition grade by grade.
- Market-specific rules. US programmes work to FDA scope; EU programmes need declarations aligned to the EU framework plus national expectations such as German BfR recommendations, and some chains require reports from accredited laboratories rather than supplier self-declarations. The factory and certificate library lists the third-party audits and test reports behind these claims, so the document request can be tied to evidence that already exists.
Fix the document refresh rule at the same time: any change of base mill, film resin, ink system or coating should trigger a document review before the next production lot ships, not a silent substitution.
6. Print, Pack-Out and the Line Trial
Brand visibility is why most chains print burger wrap at all, and print interacts directly with construction. On PE coated sheets, the logo is printed on the treated film surface, so colour matching should be approved on the actual material rather than on paper proofs, and low-odour ink systems matter because the wrap contacts hot food within seconds of assembly. On greaseproof, the print sits on a matte fibre surface that takes colour differently and shows scuffing over long holds. Wax surfaces can reject ink at the wax boundary, which produces patchy logos that look like a print defect but are a material mismatch.
Pack-out economics matter as much as the print. Sheet size drives pieces per inner pack and cartons per pallet; a wrap that is five millimetres wider can move a full percentage point out of the container plan. Interfold pattern decides whether the sheet dispenses cleanly at the assembly station or doubles up mid-rush. Lock these values before artwork is finalised, because a dimension change invalidates dielines, carton copy and case-pack data.
The last gate is the line trial: print the approved artwork on production material, run it on the real assembly station with the real product at the real hold time, and inspect the wraps that come back from the hold cabinet — grease mapping on the outside, moisture and limpness on the inside, logo integrity after handling. Samples for that trial should be requested from the printed burger wrapping paper programme with the exact construction quoted, not a generic catalog sheet, and the approval should be signed against a drawing so repeat orders reproduce it.
FAQ
What does "waterproof film coating" mean on hamburger paper?
It refers to an extrusion-laminated polyethylene (PE) film applied to a paper base. The film forms a continuous barrier that blocks both grease and water, unlike uncoated greaseproof paper, which resists grease through fibre refining but still absorbs moisture.
Is PE coated hamburger paper better than greaseproof paper for burgers?
It depends on the programme. PE coated wrap is the stronger choice for high-oil menu items, long hold times and delivery, because it blocks moisture as well as grease. Greaseproof KIT 12 is usually sufficient for fresh-served burgers with short hold windows, and it offers a more natural paper feel at a lower cost.
Is wax paper still used for burger wrapping?
Yes, mainly in cost-driven, short-hold applications, because it is the cheapest construction with decent water and grease resistance. Its limits are temperature (wax can soften and transfer), delamination under sustained heat, and market or chain preferences to move away from wax.
What KIT level should a burger wrap specification require?
KIT 12 is the top of the common scale and is a reasonable starting requirement for high-grease applications, but the KIT result must come from the supplier's own test report for the exact grade offered, and it should be paired with a moisture requirement — grease resistance alone does not predict behaviour on a held or delivered burger.
Can a logo be printed directly on PE coated burger wrap?
Yes, with the right setup. The film surface usually needs treatment and compatible inks, colour should be approved on the actual material, and low-odour ink systems are recommended because the wrap contacts hot food within seconds of assembly.
What documents should a chain buyer request for hamburger wrap?
A food-contact declaration identifying the exact construction (base, film or coating, inks), the food types and conditions covered, PFAS-free declarations where the chain requires them, and market-specific reports such as FDA documentation for the US or LFGB / BfR-aligned declarations for the EU.
Conclusion
For a QSR burger programme, "waterproof film coating" is a real construction choice, not marketing language: PE coated film paper blocks grease and moisture mechanically, greaseproof KIT 12 resists grease through fibre refining, and wax paper trades temperature headroom for cost. The right answer follows the menu's oil load, the hold time and the delivery window — and whichever construction wins, it only performs if the RFQ fixes the construction, the barrier evidence, the print side, the temperature and the document set before quotations are compared. The custom printed baking parchment paper programme publishes the test data behind each grade so specifications can be verified before ordering, and printed burger wrap formats are quoted per roll, sheet or die-cut.
