What is P-E-T ?
And why is it the best plastic card? Chemical Compound

Traditionally there are three types of card stock used and available on the market: PVC, Paper, and Laminates. Polyethylene terephthalate, or PET as it is better known, is a new material that exhibits many if not all of the desirable benefits without many of the side effects associated with the original three. PET is a non-toxic and biodegradable substance. Unlike PVC cards, those like your credit cards, PET does not crack or break. Contrary to PET's appearance, it is impossible to tear.

PET Cards are bendable

Its thinness is what makes PET so durable. Most plastic cards are 30 mil thick. PET is only 8-10 mil thick. Because of this, PET cards can be bent and curled and still snap back to shape. Of the three materials listed above, PET is the strongest.

Layers of a PET Card

    PET Card Features:

  • Thin & Light Weight
  • Durable & Reliable
  • Versatile & Flexible
  • Environmentally Friendly
  • Waterproof

The layering system of PET cards.

Besides being durable, PET is also the most environmental. The most commonly used material today is PVC, or Polyvinyl Chloride. PVC is thick, brittle, inflexible, and toxic. During use, production, and disposal of this material harmful dioxins are produced. Dioxins are hazardous substances to the earth. PET does not produce dioxins.

PET cards are long lasting. Paper cards are flimsy, permeable, and short-lived. You cannot reuse or update paper gift certificates. Instead paper tears, creases, and wears out easily. Nor do paper cards have the impressive graphic quality that PET has, such as high resolution, hologram, or foil options.

PET can embed information magnetically within its layering structure. Laminates like paper and the others don't have any security of information. They are not multi-purpose products, like PET cards. They cannot be used for several different applications simultaneously, like PET cards can. Laminates are one-time use products, limited to one visual application. Why have several different laminated cards when only one PET card is enough?

By far the most effective and cost-efficient choice of the cards is the PET card.
