State-of-the-art equipment is used to heat seal the cores with Antaeus 2000™. Scientifically formulated plastic was developed exclusively for Sunstar to inhibit moisture absorption.

Our 4 mil plastic is more effective than the typically used 3 mil plastic. Our specially formulated material reduces vapor transmission and presents the same properties of strength, flexibility, transparency and seal ability our quality control standards require. Equally important is our perfect heat seal seam.

Sunstar uses an impulse sealer that makes a perfect seam using the right combination of temperature, pressure and timing. Unlike the less-expensive hand-held sealing machines, all human variables are eliminated, so your cover gets a perfect seal every time.
