Heat shrink sealant for witches hat bottles

[Morph699]

Does anyone know where I can get heat shrink wrap or seals for the 100ml witches hat (or PET) bottle caps https://blckvapour.co.za/collections/bottles/products/nozzle-black

Ive been searching on google/amazon.com/ amazon.co.uk but nothing close to the ones I need.

I take it the caps are leaking? I have a similar problem with caps. I use old glass 10ml concentrate bottles for tester bottles, and some have caps that leak. I cut a small square of cling-wrap, put it over the bottle neck and about 1cm down the sides, poke a hole in it, and then screw the lid on. It seems to cure the problem.

nah not cos they leaking. although i have had some leak a bit but thats when i filled the bottles too high.
Im wanting to seal them to sell.
I just cant find where to get the seal, ive been searching all over even alibaba.

I would imagine that is the domain of a bottling facility? You would probably have more luck contacting industry suppliers than consumer outlets. Although I imagine it's done with an expensive industrial machine.

thanks but I was hoping that there were cheaper options. I have managed to find for smaller bottles but not for the 100ml ones.
