¡¡ |
¡¡PET Base Film |
| |
¡¡ |
¡¡Transfer and Protection Layer |
| |
¡¡ |
¡¡Magnetic Layer |

¡¡Adhesive Layer |
¡¡
¡¡¡¡¡ñ¡¡Process Method:
¡¡¡¡¡¡¡¡ At first, the transfer magnetic stripe
is ¡¡¡¡¡¡stamped onto PVC overlay by ¡°LOUDA¡±
type ¡¡¡¡¡¡¡¡¡¡machine, the magnetic layer is
released from the ¡¡¡¡base film and pulled
off. Then, the PVC overlay is ¡¡¡¡laminated
with PVC card. |
¡ñ
Recommended Process Condition:
Roller temperature£º140¡«160¡æ
Roller speed 6¡«10meter/minute
Laminate Temperature£º120¡«140¡æ
Pressure£º10¡«15Mpa. Duration£º20-25minute
The processing conditions are for
the reference only.
Their parameters should be adjusted
base on spot conditions.
¡ñ Use and characteristic:
The products, which have the features
of good temperature resistance, good
anticorrobility and long durability,
are widely used in PVC magnetic cards
based on which telecom card, identification
card. transaction cards, attendance
cards and dining card The products
are suitable for laminating techniques
