Plastic cards these days are themes of the day when it comes to presentable, smart cards for various usages from social greetings to business relation to replace paper money use to identification marking for security etc. Plastic cards fast took the place of paper cards for its style statement and more essentially longevity. The longer life of the plastic cards also made it multi purpose on one hand and reusable on the other hand. Plastic cards these days are made out of bio degradable materials these days, such as PVC. They last between nine months and five years. Besides being recyclable, the cards are also given standard limited shelf life.
The manufacturing of the cards has got a particular procedure. The plastic cards are made of several layers of plastic sheets melted and laminated together. Polyvinyl Chloride Acetate (PVCA), the clear plastic resin, commonly forms the core base of the card. This resin is then mixed with other raw materials like opacifying materials, dyes, and plasticizers to give it the proper appearance and consistency. The blended components are transferred to the extrusion molding apparatus, which forces the molten plastic through a small flat orifice known as a die. As the sheet exits the die, it goes through a series of three rollers stacked on top of each other that pulls the sheet along. These rollers keep the sheet flat and maintain the shape and right thickness. This core material, then, is laminated with thin layers of the PVCA or clear plastic materials. These laminated material get adhere to the core when applied with pressure and heat. The laminate films used to coat the core stock are made by a similar extrusion process.
