How is The Craft Favourite Adhesive Vinyl For Gifts Made?
Featuring waterproof properties and a level of durability that many modern materials simply can’t compete with; adhesive vinyl is as affordable as it is functional. From crafting to professional uses, this material is extremely versatile. Although sheets might look straight forward in nature, the actual manufacturing process could be considered extensive.
If you’re keen to learn more about how this unique material is made, then keep reading for an introduction to the process of manufacture.
What is vinyl made of?
The first component that goes into this material is polyvinylchloride polymer (or PVC, as it’s more commonly referred to). This resource will be heat treated until it becomes ductile and once a specific temperature is reached, other components will be added. The first of these is a type of plasticiser, which can help to add an extra level of durability to the formula.
It will also prolong the drying process to allow plenty of time for the composition to be modified. A manufacturer will then add pigment of a certain hue. This will help to ensure that the dried vinyl will take on a pre-defined colour (just like those that are often sold in multi-coloured sheets). Finally, a variety of preservatives, UV serums and other chemicals will be added to the mix – before the entire composition is combined by machine to ensure that the formula is spread evenly and consistently.
Casting the vinyl
The material will then be applied to air dry for a short while – simply to allow the formula to return to a more ductile state. Once slightly hardened, the material will then be rolled and fitted to a pole, ready for wrapping. At this stage, it’s important that the entire formula is rolled into a rough square shape – as this will minimise the time that it will take for another machine to cut the role into sheets.
The rolling machine will then get to work to wrap the vinyl in much the same way as a roller blind, or similar product. The vinyl will be rolled continuously to avoid the risk of air bubbles forming. This process can also help to ensure that the thickness of the material is consistent; which can also make cutting much easier.
Finally the entire roll will be removed and fitted to a cutting machine. It will then be unravelled and cut to size and shape (typically in smaller quantities for crafting purposes, but larger sheets are also manufactured for industrial uses). Once cut, the sheets will be collated where they can be properly prepared and packaged; ready for distribution. And it’s these packages that are sold in craft stores, DIY outlets and other similar shops.
