Q: Why doesn’t anything stick to gas tanks?
Vinyl will not stick to plastic gas tanks for very long. Initially it will stick, but the plastic is porous and under pressure. Petroleum will penetrate the plastic; the vapors are usually under pressure, and are forced through the sides of the tank into the adhesive. That will cause the adhesive to release. The appearance is called “blistering.” You can push it back down for a while, or clear-coat an area on the tank before putting gas in it.
Another option is to buy an aluminum tank, if one is available and you really want graphics on the tank.
Q: What are those tiny bubbles that seem to appear under the laminate?
The industry term is called “silvering.” When the liner is pulled off pressure sensitive adhesive it creates small points where the adhesive releases. In between those points, air gets trapped. As the adhesive sets, it smooths out and the air bubbles dissipate. If you have the option of heating the laminate (we suggest 100˚F), it will aid in softening the adhesive and reducing the appearance of air bubbles. One thing to keep in mind, is that the faster you laminate, the more air will be trapped. Either way with vinyl, the silvering will go away over time. It will typically take from one to 8 hours to fully dissipate, depending on the ambient temperature and the softness of the adhesive being used. With Convex and Pro-Shield laminates, it’s usually gone within 4 hours from the time you laminate.
Why is there a splice in some rolls of material?
There is a beginning and an end to each roll of film and each roll of liner. GMS makes short runs of unique custom materials on demand. Therefore splices are a common part of production. The average is 10% of our rolls, but we limit it to one splice if any.
Our production team places markers along the edge of the material just before and after the splice. When you handle the roll, you can’t miss them. We do this so you can work around a splice. We also add at least an additional 5 ft. of material to the roll to compensate for any waste.
On large runs, you won’t see spices because it costs very little to throw the small amount away and amortize it over a longer run. With short runs of materials, that can amount to a 25% cost increase. Production costs or savings always affect the price.
