Polytunnel Zips replaced with Velcro or some fitting

magnets maybe?

Take it to a Haberdashery?

I wouldn't recommend adhesive backed Velcro - the adhesive comes unstuck before the Velcro does. I bought some non-sticky velcro type tape which can be sewed down instead of stuck, from VST Fabrics Ltd. No doubt there are other suppliers.

You can get self adhesive velcro rolls, two of course, but I'd be a bit wary of the glue outdoors.

Magnetic rubber strip?

Zips seems a bit OTT for a polytunnel.

Last one we had here the entrance was two timber uprights with the polythene cover secured with staples.

The door was a strip of polythene secured at the top, slightly wider than the entrance and tacked to a series of battens. The battens were pierced at either end to take cords attached to the top and bottom of the doorway. A third cord fixed to the middle of the bottom batten passed through an eyelet at the door head could be used to adjust the opening to control ventilation.

Stagnant air is not good in a greenhouse.

Biggest problem is when the Sun heats the metal frame and destroys the plastic cover where it touches.

Those Gardman plastic covers only last about two summers before they rot into a net like structure. Bought some of their large cloches to grow our chillies under, have to find a new cover material now although fleece works OK. Might try bubble wrap as I have a roll.
