Thanks to the internet, we are all heir to an almost unprecedented amount of information about vinyl films. These days, you don't have to be a sign shop owner or in the creative department of a large company to have access to the full array of adhesive vinyl films on the market. Still, knowing whether to choose Avery™ SC950 Ultra Metallic versus ORACAL® 631 Cal film can be almost impossible if you know nothing about the differences in the films. But, wait, there's more. In addition to true vinyl films many brands offer polyester films too which can make it even more confusing. Plus, if you're a true beginner, you may not even know what you want to do wit the film. In the following article, we'll look at the general types of vinyl film out there and then break them down even further into specific applications.Get more news about vinyl film,you can vist our website!

There a more than a few ways we could start but it might be best to start off by differentiating between adhesive vinyl and heat-transfer vinyl (also commonly referred to as HTV). Adhesive vinyl is by far the more common type and is just that: a vinyl film with a sticky (adhesive) side and a non-adhesive, colored face. Heat transfer vinyl, on the other hand, is a specialty vinyl that may be used on fabrics and other materials to create designs and promotional products. Generally sold in a roll or sheet form with a heat-activated adhesive backing so it can be cut, weeded, and placed on a substrate for heat application. Because we only specialize in adhesive craft, sign and wrap films we won't be discussing this type of film further but Siser HTV is one of the most well-known and trusted brands if that's what you're looking for.

The next major division of vinyl films is with regard to how they are manufactured. This, in turn, tells you a lot about their suitability for various applications and end uses, their durability and, of course, their cost. There are currently two primary forms of mass production of vinyl films and they are casting and calendering. We'll go into some detail below but, for a more in-depth analysis, check out our article on the differences between cast and calendered vinyl .

Cast vinyl film is made through a process referred to as casting. In other words, the material that will eventually become a sheet or roll of cast vinyl starts out as a mixture that resembles a thick, viscous plastic paint. Plasticizers, PVC and pigments (dyes) are mixed together until a homogenous mix known as organosol is formed. The mix is the cast or measured out onto a moving matrix called the casting sheet where it is subsequently processed through a number of different ovens where the solvents that liquefied the mix are evaporated. The solid film that remains is then rolled onto large cores (kind of like the cardboard cores you see on larger 50 yard rolls of film) where the adhesive coating is applied to one side.
