Material for blocking light to flower?

Hi, I’m ready to start flowering half my crop so I need to split my grow space so I can keep the other side vegging and am looking for some ideas on what I could/should use to block the doorway opening from light for the 12hr dark? I was originally thinking of hanging some type of tarp with Velcro so no light can get through but I’m not sure if it will be dark enough.

Just curious if anyone had any tips on materials/sheeting to use, it has to be something that can be moved/opened easily for access, the size is to small for a standard door.

Thanks!

like above post said panda film, one side is like 94 reflective the other side lets no light through at all. I'm about to put my flower room together with some of this.
