Can You Microwave Parchment Paper? Here’s What’s Actually Safe

At ProPackInsights, we get asked about food-safe paper more than almost any other packaging topic — and “can I put this in the microwave” is the question behind most of it. The short answer for parchment paper is yes, but the longer answer matters more, because not every paper in your kitchen behaves the same way once it hits the heat, and mixing them up is how you end up with a scorched patch on your microwave floor.

Here’s the full breakdown: what parchment paper can handle, how it differs from wax paper, which other kitchen papers are safe, and which ones genuinely aren’t.

Is Parchment Paper Microwave-Safe?

Yes. Parchment paper is coated with a thin layer of silicone, and that coating is specifically what makes it heat-stable — silicone stays chemically inert at temperatures well beyond what a standard microwave generates. Microwaves heat food through radiation that excites water molecules, not through direct flame or a heating element, so parchment paper isn’t fighting against the kind of intense, localized heat it would face in a conventional oven.

That means you can safely use parchment paper to cover a dish and prevent splatters, line a plate for reheating something sticky, or wrap vegetables loosely for steaming. It holds up well across all of these without breaking down, smoking, or transferring anything into the food.

Why Parchment Paper Handles the Microwave So Well

It comes down to that silicone coating specifically. Silicone-treated parchment paper can generally tolerate heat up into the 420–450°F range before it starts to scorch — a threshold most microwave use never comes close to, since food itself typically doesn’t exceed the boiling point of water (212°F) unless it’s been microwaved dry and unattended for an unusually long stretch. The paper isn’t the limiting factor in a normal microwave use case; the food is.

Can You Put Wax Paper in the Microwave?

This is a different question with a more conditional answer, and it’s worth separating clearly from parchment paper since the two get confused constantly. Wax paper uses a paraffin wax coating rather than silicone, and paraffin has a much lower melting point. In short bursts, wax paper generally tolerates microwave use fine — but if it makes direct contact with something high in fat or sugar that gets very hot, or if it’s left in for an extended cook time, the wax coating can begin to melt or transfer onto the food.

The safest approach with wax paper in a microwave is short, monitored heating with the paper not directly touching the hottest part of the food. If you’re regularly deciding between wax paper and parchment paper for kitchen tasks generally — not just microwave use — our wax paper vs butter paper guide breaks down the coating differences and where each one actually belongs.

Can You Put Paper in the Microwave? (General Paper Types)

Beyond parchment and wax paper specifically, there’s a broader question that comes up just as often: is paper in general microwave-safe? The honest answer is “it depends which paper,” so here’s how the common kitchen and household papers break down:

• Paper towels — Generally safe, and commonly used to cover food or absorb moisture during reheating. Stick to plain white, uncoated towels; printed or dyed towels can occasionally bleed color under heat.
• Printer or notebook paper — Not recommended. It’s not food-grade, may contain inks or coatings not tested for heat contact, and isn’t designed for moisture exposure the way food-safe papers are.
• Newspaper — Avoid. Newsprint ink isn’t formulated for food contact, and the paper itself is thin enough to scorch faster than purpose-made kitchen papers.
• Cardboard (takeout boxes) — Short reheats are usually fine for plain, uncoated cardboard, but many takeout containers have a thin plastic or wax lining that isn’t microwave-safe — check for a wax sheen or plastic window before assuming it’s fine.

The pattern across all of these: purpose-built food-contact papers (parchment, wax, plain paper towels) are the safe category, while anything printed, dyed, or laminated for a non-food purpose is the one to skip.

Butcher Paper, Deli Paper, Freezer Paper & Sandwich Wrappers in the Microwave

These four get searched constantly and deserve direct answers, since they’re common enough to have in the kitchen but different enough in construction to behave unpredictably.

Butcher paper is typically uncoated or very lightly coated, and it’s generally fine for brief microwave reheats — a few minutes covering a plate, similar to a paper towel. Because it’s more porous than parchment, it won’t trap steam the same way, which is actually useful for reheating something you don’t want to go soggy.

Deli paper (the kind wrapped around sandwiches and sliced meat) is usually a light wax or grease-resistant coating, closer to butter paper than parchment. Short reheats are typically fine, but it’s not built for sustained high heat the way parchment is.

Freezer paper has a plastic-coated side designed specifically to resist moisture in cold storage, and that coating isn’t formulated for microwave heat — it’s better to remove freezer paper before reheating rather than assume it behaves like parchment.

Sandwich wrapper paper (the kind used by sub shops) varies by brand, but many use a light wax or paper-plastic laminate. Brief reheats are usually low-risk, but if the wrapper feels glossy or plastic-like rather than matte and paper-like, it’s safer to remove it first — that glossy finish usually signals a plastic layer not meant for heat.

How Long Can You Microwave Parchment Paper?

There’s no fixed universal limit, since it depends on your microwave’s wattage and what’s cooking underneath the paper — but as a practical guideline, parchment paper handles typical reheating and steaming tasks (2–5 minutes) without issue. For longer cook times, it’s worth checking the food periodically rather than running one long, uninterrupted cycle, mostly because extended heat gives whatever’s under the paper more chance to get hot enough to affect the paper indirectly, not because the parchment itself degrades quickly.

Parchment Paper vs Wax Paper vs Plastic Wrap for Microwave Use

Material	Microwave-Safe	Heat Tolerance	Best For
Parchment paper	Yes	High (up to ~450°F)	Covering, steaming, reheating
Wax paper	Conditional	Low–moderate	Short reheats, away from direct high heat
Plastic wrap (microwave-safe)	Yes, if labeled	Moderate	Covering to retain moisture, avoid direct food contact

Plastic wrap holds a slight edge for creating a tighter moisture seal, but it needs to be microwave-labeled specifically and shouldn’t touch the food directly, since heat can cause some plastics to leach compounds into whatever they’re touching. Parchment paper sidesteps that concern entirely, which is part of why it’s increasingly the default choice for anyone trying to reduce plastic use in food prep. If sustainable food packaging is something you’re weighing more broadly — parchment versus plastic-based wraps across your whole kitchen or business — our comparison of plastic vs paper packaging covers the environmental trade-offs in more depth.

Tips for Safely Microwaving Parchment Paper

A few habits make the difference between a clean reheat and a scorched one:

1. Keep it away from the microwave walls. Direct contact with the wall or turntable edge is where scorching is most likely to start.
2. Don’t seal food airtight. Leave a gap or a small vent so steam can escape rather than building pressure under the paper.
3. Avoid very high-fat foods under tightly wrapped paper. Fat gets hotter than water content alone, and can bring the paper closer to its scorch threshold.
4. Use short intervals for anything unfamiliar. 30–60 second bursts let you check progress before committing to a longer cook.

What Not to Put in the Microwave

While parchment, wax, and most plain papers are fine within the guidelines above, a few materials genuinely don’t belong in a microwave regardless of how they’re wrapped: anything with metallic ink or foil backing, twist ties with a wire core, and takeout containers with a metallic sheen. These aren’t paper problems specifically — they’re metal problems, since metal reflects microwave radiation rather than absorbing it, which is what causes sparking.
