The shelf life of vinyl is influenced by below factors:
1) The film formula, meaning the amount of plasticizer that gets transferred to the adhesive
2) The sensitivity of the adhesive to plasticizer contamination.
3) The storage conditions, overheated or wet condition will be problematic.
Graphictac recommends storage at temperature 25°C and 50% RH for one year shelf life, if not stored properly, the followings may occur:
- The liner may expand at the area of moisture contact, causing the film surface to be mottled.
- The silicone release coating on the liner will become inconsistent and cause difficult weeding.
- The paper will tend to curl or become wavy when it is unwound, making it difficult to cut/ weed/ install.
Do not lay heavy rolls on their side for a long period of time.
It’s important to keep the product in its original packaging in a cool and dry place.
