Can I do one sided lamination with my roll laminator?
Two-sided roll laminators apply film to both sides of a document simultaneously — that's their designed function. But plenty of legitimate applications require laminating only one side: repositionable display signs where the back needs to remain uncoated, canvas prints where one side should stay paintable, documents that will be mounted on a backing board and need a clean uncoated surface for adhesion, and specialty print applications. This guide covers the correct techniques for running one-sided lamination on a two-sided machine without damaging the machine or producing a poor result.
For an overview of roll laminating film types before reading the one-sided technique guidance here, see our film guide at what you should know about laminating film.
What Is One-Sided Lamination and Why Is It Challenging on a Two-Sided Machine?
One-sided lamination applies clear protective film to only one face of a document, leaving the other face uncoated. In pouch laminating, this isn't an issue — you simply use a single-sided pouch or place the document against one side only. In roll laminating, the challenge is that a two-sided roll laminator feeds film from both an upper and a lower roll simultaneously, applying heat and pressure to bond both films to both sides of the document in a single pass. The machine is mechanically designed for this dual-film application, and there's no simple "off switch" for one roll.
Running one-sided lamination on a two-sided machine requires a workaround: either preventing the second film from bonding by interposing a release material between the film and the document on one side, or using a specialized one-sided laminating film. Both approaches work reliably when executed correctly. For the complete roll laminator setup context, see our threading guide at loading laminating film without a threading card. For the heat-assist lamination that works alongside standard one-sided techniques, see our guide at heat-assist laminator guide. For laminator brand selection for roll laminating, see our comparison at Fellowes vs GBC laminators.
The fundamental challenge: A two-sided roll laminator applies heat and pressure to both sides simultaneously. One-sided lamination requires preventing adhesion on one side without removing the film from that side entirely — because removing the film leaves the bare roller exposed.
Method 1 — Kraft Paper as a Release Layer
The most accessible and widely used method for one-sided roll lamination is running a sheet of kraft paper (uncoated, unbleached brown paper) between the film and the document on the side you don't want laminated. The kraft paper acts as a release layer — the film bonds to the kraft paper surface rather than to the document, and because kraft paper doesn't bond permanently to the laminating film's adhesive under normal conditions, the kraft paper and film can be separated after processing.
The procedure: thread both rolls of laminating film on the machine as normal. Feed a sheet of kraft paper (slightly wider than the document) into the machine on the side that should not be laminated, positioned between the roll film and the document surface. The document runs through the machine sandwiched between the film on the desired side and the kraft paper on the non-laminating side. After processing, separate the kraft paper from the film — the film has bonded to the kraft rather than to the document on that side. For the correct film threading technique that precedes this process, see our guide at loading laminating film without a threading card.
Kraft paper specifications for release
Standard kraft paper in the 50 to 60 lb (75 to 90 gsm) range works well as a release layer. The paper's uncoated surface doesn't form a strong enough permanent bond with standard laminating film adhesive under typical heat-assist conditions. Do not use coated paper as a release layer — coated surfaces bond more aggressively to laminating film adhesive and may tear when separation is attempted.
Method 2 — Silicone Release Paper
Silicone release paper is specifically manufactured to not bond to pressure-sensitive and thermal adhesives — it's the same material used as the backing on adhesive labels. Running silicone release paper as the release layer on the non-laminating side provides a more reliable non-bond than kraft paper, particularly at higher machine temperatures where kraft paper's release reliability decreases slightly. Silicone release paper is available from laminating supply distributors and produces consistently clean separation from the laminating film after processing.
Method 3 — Specialized One-Sided Film
Some laminating film manufacturers produce one-sided laminating film specifically designed for two-sided machines. These specialty films have an adhesive layer on one side only — the non-adhesive side is a release-treated surface that bonds to the roller but not to the substrate. This eliminates the need for any release paper workaround. One-sided specialty film requires sourcing from suppliers who carry it, and it's less widely available than standard two-sided film. For organizations that perform one-sided lamination regularly, investing in one-sided specialty film provides the cleanest, most reliable results.
How to Run One-Sided Lamination on a Two-Sided Roll Laminator — Step-by-Step
Step 1 — Thread both film rolls as normal
Thread the machine with standard laminating film on both upper and lower rolls. The machine should be threaded completely with both films meeting at the nip point. Do not leave one roll unthreaded — a bare roller without film in a heated laminator can develop surface damage from direct heat exposure.
Step 2 — Prepare the release paper
Cut kraft paper or silicone release paper to slightly wider than the document width. The release paper should extend beyond the document edge on both sides to prevent the edge of the film from bonding directly to the document on the release side.
Step 3 — Feed document between film and release paper
Feed the document into the laminator with the film on the side to be laminated and the release paper on the side that should remain uncoated. Timing the feed so the release paper and document enter the nip simultaneously is the key execution step.
Step 4 — Process at correct temperature
Run at the temperature appropriate for the film thickness being used. One-sided lamination produces adequate results at standard temperatures. Reducing temperature slightly (10°F below standard) can improve release paper separation after processing.
Step 5 — Separate release paper from film after exit
After the document exits the machine, carefully peel the release paper away from the film on the non-laminated side. The film should remain attached to the release paper and come away from the document surface cleanly. For trimming the finished piece, see our laminating stand-out guide at how to make laminated documents stand out.

Troubleshooting
Film is bonding to the document on the release side despite kraft paper
The machine temperature is too high for the kraft paper release method. Reduce temperature by 10°F and test. At temperatures appropriate for heavier films (7 mil +), kraft paper's release effectiveness decreases. Switch to silicone release paper for higher-temperature applications.
Release paper is tearing when separated from the film
The film has bonded too aggressively to the kraft paper. This can happen with some film formulations or at higher temperatures. Pull at a very shallow angle rather than straight back — shallow-angle peeling reduces the force required for separation. Or switch to silicone release paper.
Film from the release side is coming off in fragments, leaving adhesive on the document
The film formulation is more aggressive than the kraft paper release can handle. Increase kraft paper thickness, add a second layer of kraft paper, or switch to silicone release paper.
Film roll tension on the release side is causing the document to curl
Both film rolls apply tension to the document through the nip. The release paper absorbs the film tension on the non-laminating side, but if the release paper is loose or misaligned, unequal tension can cause curl. Ensure the release paper is taut and equal width to the document when feeding.
Machine is making unusual noise during one-sided runs
The release paper method doesn't change the machine's mechanical operation. If unusual noise occurs, confirm the paper stack (document + release paper) isn't thicker than the machine's rated material thickness.
Frequently Asked Questions
Can I simply not load one film roll for one-sided lamination?
No — leaving one roller unloaded while the other roller runs film creates unequal roller pressure and exposes the bare roller to direct heat, which can damage roller coating. Always load both rolls and use the release paper method for one-sided lamination. For film loading guidance, see loading laminating film.
Is one-sided roll lamination appropriate for canvas prints?
Yes — canvas prints that need one side laminated for display and the other side uncoated for mounting on stretcher bars are a common one-sided lamination application. The silicone release paper method works reliably for canvas because canvas has enough surface texture that even slight adhesive bonding from standard kraft paper would be problematic.
What film thickness works best for the kraft paper release method?
3 mil to 5 mil films work most reliably with the kraft paper release method. Heavier films (7 mil +) apply more heat and may reduce kraft paper release effectiveness. For heavier films, use silicone release paper. For film thickness selection guidance, see laminating film thickness guide.
Can I use regular white paper instead of kraft paper as a release layer?
White coated paper is not suitable — the coating bonds to laminating film. White uncoated bond paper (standard copy paper) can work similarly to kraft paper for the release method at standard temperatures. However, kraft paper's fiber structure makes it somewhat more reliable for this application than standard bond paper.
How do I trim the one-sided laminated document cleanly after processing?
The release film on the non-laminated side may have a slightly uneven edge from the separation process. Trim all four sides with a rotary trimmer for clean, consistent edges. A sharp blade is especially important after one-sided lamination since the non-laminated side requires extra care to avoid fraying. For trimming guidance, see laminated document stand-out techniques.
