Teslin Cards Manufactures
Quality Library Cards at Dasher Printing
We produce different products, but whether you call them children’s library cards, library credit card key tags, or bar-coded cards and key tags, they are all produced the same way; the only difference is the copy and the die cut.
The most crucial aspect of all our products is that Dasher Printing uses only Teslin as our core material.
Don’t be misled by vendors saying they use a synthetic material to make you think you are getting Teslin. Teslin is a synthetic substrate produced by PPG Industries that bonds physically and chemically with hot lamination and has the best porosity (the ability to absorb ink and adhesive) on the market today. Many manufacturers use the term Teslin as if it is a process, not a brand name, leading you to believe that you are getting the same quality.
Credit card manufacturers usually use PVC as their core material because it is very rigid. In the first years, the way of numbering a card was to emboss it. In later years, the embossed numbers were replaced by magnetic strips with the customer information. This works exceptionally well for credit cards. As technology progressed, barcodes became the new way to assign numbers to individuals using cards. The rigidity that makes PVC so great for magnetic stripes was negative for applications like library cards because the barcode had to be burned into the lamination on the outside of the PVC card, leaving it unprotected.
A composite card uses a flexible synthetic material, with the barcode and copy printed on the core material; the card is laminated, then die cut to the final size with the printing and barcode under the lamination. Many manufacturers refer to the process of having the barcode under the lamination as a Teslin card, describing the process, not the brand name material, which is misleading.
The synthetic used as the core material determines how long the card will last. If you produced two identical cards, the only difference was the core material, and the Teslin card lasted 10 times longer than the synthetic card. You can decide if you want a card that costs less or will last up to 10 times longer.
