Application
tape manufacturers package their products in plastic sleeves, then box them in
corrugated containers to protect the tape from light, dirt and humidity. If
you’re not going to use the tape immediately, keep it in its box. Tape not
stored in boxes is exposed to light, which can cause yellowing. Even shop
lighting can yellow application tape.
Stacking rolls of application are horizontally can cause a flat spot on the tape roll, making unwinding more difficult. |
This
yellowing occurs because the light begins to degrade the natural rubber
adhesive. Although this degradation isn’t generally significant to adversely
affect product performance, it’s aesthetically unpleasing.
Yellowing
caused by light detracts from an application tape’s appearance. However,
storing a pressure-sensitive product in an excessively hot environment is more
harmful. Prolonged exposure to temperatures above 85°F prematurely ages an
adhesive and degrades its performance. Years ago, I met one sign maker who kept
his application tape in the refrigerator. Wonders never cease! My advice is to
store your beer in the fridge, and keep your tape in your shop’s coolest area.
As
tapes age, their performance often declines and becomes problematic. Old
application tape can “block-up” on the roll — the adhesive binds to the
facestock’s first surface, making the product difficult, and often impossible,
to unwind. All pressure-sensitive products have warranted shelf lives; for
application tape and premask, it’s six months.
Consequently,
you should rotate your tape inventory. The material first entered into
inventory should be used first. Furthermore, handle your application tape with
care — damage to a roll’s ends impairs unwinding the tape. The paper easily
tears where it’s damaged.
Finally,
application tape rolls should be stacked upright. Stacking them horizontally
causes a flat spot on the tape roll, making unwinding more difficult.
