This means you can peel it up and re-position (before pressure has been applied) if you get a bubble, for example, without the vinyl stretching out of shape. "T here is less chance of an edge getting nicked and lifted prematurely (especially from high pressure washings)," Oracal tells me.īecause 751 is more flexible, it's considered repositionable when lightly applied. It's Thinner - 751 is 0.5 mm thinner (2mm) than 651 (2.5mm) which means it's more flexible, conforms better, and flatter (is that a word) to the hard surface where it's applied.What does that mean to us as crafters? It means a lot! There are several advantages to cast (751) over cal (651 and 631): And that is true.but it's not always all about the adhesive strength when it comes to vinyl - it's how they're made.Īdvantages of Oracal 751c vs 651 and 631 Without getting too geeked up on vinyl, Oracal 751 vinyl is a cast vinyl while 651 and 631 are calendar vinyls. One thing that a lot of crafters and hobbyists get hung up on is the fact that Oracal 751 and 651 share the same adhesive strength.
