Have you ever wondered if resin sticks to plastic wrap? You’d think that the answer was simple: yes, or no. But this question is a little bit more complicated than it initially appears. To understand why we need to discuss what resin actually is and how it behaves.
Resin is a material used in many different projects. It can be used as an adhesive, filling gap between two objects, or as a protective coating that gives shine to something else.
Epoxy resins are often clear and very hard once they’re dried—they can be used as substitutes for glass when they’re dried completely!
Plastic wrap is another common material found in many homes across America.
This thin plastic film lines inside containers made of other materials so that food can stay fresh longer and remain covered while the container lid is off.
The two materials have some similarities (although the most obvious similarity is that neither one of them tastes good).
Does epoxy resin stick to Saran Wrap?
Yes, epoxy resin will stick to Saran Wrap. But you may need to change your technique.
It works well to use Saran Wrap as a mold release product when casting epoxy resin into molds.
It’s easy, it’s cheap and it doesn’t leave a residue on the mold that might affect the finished piece.
There are three things to consider when using this method:
- Make sure your Saran Wrap is completely smooth and wrinkle-free on both sides
- Make sure you coat the sides of your mold with epoxy resin before using the Saran Wrap
- Don’t use too much epoxy resin for each layer you pour into your mold or it will seep out under the wrap and make it stick

How do you keep resin from sticking to plastic?
- Use a mold release.
A mold release is a coating that you can spray onto the plastic before you pour the resin. This will prevent the resin from sticking to the plastic wrap and make it easy to remove when you are done.
- Don’t use a mold release.
A more natural approach would be to skip using any sort of mold release altogether and let the plastic wrap do its work naturally.
After curing, carefully peel off the plastic wrap and you should have a perfectly formed piece of resin without any extra chemicals used in production!
- Use wax paper.
If you want something even more natural than plastic wrap, why not use wax paper? Similar to using just plain old plastic wrap, this technique will still require some peeling when removing your finished product but it’s much healthier for your body and better for our environment too!
Does epoxy stick to plastic?
Epoxy resin does stick to plastic, as long as a few criteria are met.
The most important thing is to make sure the plastic surface is clean and free of any dirt or dust.
Once you’ve done that, you can apply a coat of resin and let it dry.
What does not stick to epoxy resin?
Does epoxy resin stick to plastic wrap? Nope. For example, the plastic wrap I had on hand is called Glad Press ‘n’ Seal and it’s manufactured by Clorox.
It comes in a yellow box with a blue stripe across the front. Epoxy resin has no trouble being peeled off this brand of plastic wrap!
Does epoxy resin stick to plastic bags? No. The most commonly used brand of grocery store bag is made by Trex, or “The Trex Company.
(Ever notice that?) You’ll have no problem releasing cured epoxy from these bags; they’re not sticky and they don’t pick up fingerprints either.
Does epoxy resin stick to aluminum foil? Definitely not! Aluminum foil is so non-stick that it can be cut cleanly with scissors and then rolled into a ball without any force at all it just pops up when released from your hand.
If you want something more permanent than paper mache or plaster for your mold, try using aluminum foil instead of baking soda because aluminum does not melt under high temperatures like baking soda will at about 5 degrees Fahrenheit above boiling point.
Does resin melt plastic?
Yes, resin can melt polyethylene and polypropylene plastic. The good news is that these types of plastic are commonly used to make single-use water bottles, Ziploc bags, and even toys, so you should be able to find some good candidates for your molding project.
Just make sure you get the right plastic for the job resin won’t work with all plastics!
In addition to melting plastic, resin can be used to restore melted plastics’ original shape.
You may remember from elementary school science class that certain materials (like wax paper) shrink when they get hot; this is called “shrinkage.”
If your plastic has shrunken (or worse) due to excessive heat exposure, curing it in an epoxy resin like EnviroTex Jewelry Resin will hold it together while also preserving its original shape!
Does resin stick to foil?
No, resin will not stick to foil. In fact, you can use tin foil to create a mold for your resin piece. Here are the steps on how to do this:
- Place a thick piece of tin foil on a flat surface (it might help to tape the edges down with painter’s tape).
- Using your fingers, press and stretch the tin foil until it has formed the shape you want. Keep in mind that once cured, the resin will have a shiny finish so any texture you put into the mold will be replicated on your finished piece.
- Let cure for at least 24 hours, or as recommended by your resin manufacturer’s guidelines (don’t forget about those!). If you need to leave it overnight, make sure that nothing disturbs it and that no pets or children are anywhere near!
- Remove from mold and enjoy!
Can you put resin on plastic cups?
Good news: yes, epoxy resin will bond to plastic cups.
Bad news: no, you shouldn’t use them. There are a few reasons why this is a bad idea.
First: heat. Epoxy resins cure through exposure to heat, and since plastic cups aren’t oven-safe, the heat of your oven will cause the cup to melt into your resin and art piece (and could also ignite).
Second: release agents. Because resins are sticky and thick, many artists use release agents such as Vaseline or cooking spray to keep their projects from sticking to the surface they’re being poured onto.
The issue here is that these release agents can cause chemical reactions between your materials that result in an unevenly-cured resin project and nobody wants that!
Third: durability. Plastic doesn’t hold up well over time, so even if you were able to cast successfully using a plastic cup, you wouldn’t have a project that was built for longevity.
This isn’t ideal for anyone who’s planning on displaying their masterpiece at home or selling it in person at craft shows or fairs#$END OF SECTION
Do you need mold release for resin?
The answer to this question is not every time. You will not need mold release if you are using silicone molds.
Silicone molds are specifically designed to be used with resin and other materials, so they don’t require any sort of release agent.
You will need to use mold release if you are using plastic molds. There are two types of plastic: hard and soft plastic.
These both require the use of mold release because they were not made to be used with the types of materials that resin requires.
Conclusion
In conclusion, epoxy resin does not stick to Saran Wrap.
However, you should be careful with the plastic wrap because it can melt if it gets too hot.
