Crisper

 

Crisper is a unique white, polyester based product produced by Toyobo in Japan which is finding acceptance in this country based upon an excellent combination of properties and costs.

 

The advantages to using "Crisper" are numerous. The following highlights its outstanding characteristics:

  1. "Crisper's" specific gravity of 1.1 offers yields of 20% more than regular clear polyester film, and 22% more than regular white polyester film.

  2.  "Crisper" is available in thinner gauges than Kimdura, and other olefin based products.  Calipers from 38 microns (1.5 mils) up to 250 microns (10.0 mils) are available.

  3. "Crisper" being polyester based can take a higher heat environment than competitive olefin based films.  300 degrees (F) for 30 minutes is not a problem. This means that it can take the fusing temperature required for solid toner copiers and laser printers.

  4. "Crisper" is precoated to accept copier toner, and anchors it so well it cannot be erased from the surface.  Laser printing with "Crisper" gives sharper definition and truer bar codes than most competitive films.

  5. "Crisper's" precoated surface is "smudge proof", and most Thermal Transfer Ink ribbons will not smear.

  6. "Crisper's micro cellular back surface can also be chemically pretreated to accept and anchor to most common adhesive systems.

  7. "Crisper's" matte print surface will not cause improper reads in Bar Code readers as sometimes happens with glossier stocks.

  8. "Crisper" can be ordered with antistat built into the sheet (Type 23) at no additional cost, allowing it to be sheeted and printed by offset lithography.

  9. "Crisper" is white, bright, and opaque, but these properties are attained without using particulates such as calcium carbonate which can often interfere with Direct Thermal and other coatings.

Advantages of using "Crisper" for RFID application

"Crisper" is the White Opaque Synthetic Paper based on Polyester which contains numerous voids in it and is top-coated to promote adhesion to most printing inks and industrial coatings. These features allow us to offer the following advantages for RFID application and "Crisper" is an optimal material for RFID compared to other materials including paper, regular PET film, PP and olefin related film etc.

Numerous voids

  1. Cushioning Property
    Due to the numerous voids, the specific gravity of "Crisper" is 1.1g/cm3 while that of regular PET film is normally 1.4g/cm3, which enables "Crisper" to provide its cushioning property.

    IC chips and lead wires are embedded in or sandwiched between materials in most RFID labels and tags. In whatever form, during these converting processes, there is an unavoidable amount of pressure applied to the material. This pressure often causes damage to the chips and lead wires, which raises the loss ratio as well as material loss. "Crisper" can reduce this loss ratio due to its cushioning property compared with the use of regular white PET.

  2. Low Dielectric Loss
    The dielectric constant of "Crisper" lies between Polypropylene and PET film. The dielectric loss of "Crisper" is smaller than PET film. That's why the absorption of the electromagnetic wave is little and the energy effectiveness is good. "Crisper" is recommended to use Flat cable, Communication cable, IC Card and IC Tag.

  3. Recognition Rate
    Because the dielectric loss of "Crisper" is small, there will be much fewer errors in reading the chip.

  4. Electric Property
    The volume resistance of Crisper is     and is used as insulating material.

  5. Thermal Property
    The insulating characteristics of "Crisper" is suited to Re-Writable coating for direct thermal. The numerous voids trap heat which allows printed characters to appear and disappear sooner with less energy used than with the other related material.

Based on PET

  1. "Crisper" offer higher heat resistance than paper and polypropylene film. For some RFID labels and tags, electrically conductive lead(lead wire) is imprinted using copper ink. After printing, some heat has to be applied to the material for curing purposes by a hot-air dryer. "Crisper" can endure this heat because of being PET base, while paper and polypropylene material cannot.

  2. Durability
    "Crisper" has better durability than paper and polypropylene film. The customers can anticipate that the total cost will be reduced with repeated use.

  3. Stability
    "Crisper" is more stable (Adherence, Thermal Resistance, Shrinkage) than paper and polypropylene film, which makes any converting process easier and faster.

  4. Chemical Resistance
     "Crisper" has a Chemical Resistance against acid, alkali solvent, organic solvent and so on.

Top Coating

  1. Printability/Adhesion Property
    The uniquetop-coating of "Crisper" has an excellentaffinityto various printing inks, resins and industrial coatings. Re-write coating for direct thermal can be made on the surface of "Crisper".

  2. Anti - Static property
    The top coating contains an anti-static agent, which leads to the reduction of damage to IC chips by static discharge.
