Corrugated Plastic for M & P Mold

[homesteaders]

I'd like to make a small loaf mold from a corrugated plastic sheet. I've never worked with melt & pour. I thought about just taping the mold together since it will be small -- about 1.5" x 1.5" x 8". Will I need to line the plastic sheet mold with butcher paper, as I normally do for hp and cp soaps, or will the soap separate from the plastic pretty easily without any liner when I remove the tape?
Thanks!

M&P usually releases from the molds better than CP or HP soap.

Thank you for letting me know! Sorry for the delay. I just saw your response.

Not sure> Maybe if you put some mineral oil, or cooking spray before pouring. You may have a hard time getting it out.

And you better sealed those corners really good. It might bleed though the mold if there is any place not sealed.

Thank you. After posting, I thought it would be better to use hot glue at the seams rather than just tape. Maybe I'll line with freezer paper the first time, and dribble a little on the corrugated plastic to see if it comes off easily before trying an unlined mold. Thanks for the suggestions.

Hot glue is not going to hold it ... and as soon as the heat of the soap touches it, it will probably come apart

What size is your batch? I can give you a couple of suggestions...

Binder clips will hold it together sufficiently without leakage if you fold it you make it like done in this video:

Thank you both for the tips!!!! Good video on making a quick, simple soap mold. I'm just learning about M&P. Quite different from hp and cp.
