Sheet format backing cards for rapid diagnostic test kit is made of PVC,PS or PET materials with self-adhesive.
1.Strong adhesive force but low amount of adhesive use
Compared to the common adhesive used on the market, our adhesive is a stronger type, so that we only need small amount of adhesive-20g/square meters to maintain strong sticking force, whereas other backing card producers have to apply 35g/squre meters on it. As a result, it will significantly reduce the maintenance frequency for the cutters and increase the product acceptance rate, this merit is especially good for large production which engage a lot of automatic instrument.
2. Extreme low rate of cold-flow characteristic
which made it very stable performance with high resistance to aging. Suitable to stick no-backing NC membrane and surfactant treated glass fiber(for sample pad or conjugate pad), especially good for DOA test kit and food safety test kit.
3. Good Flatness
Whether the backing card sheet is in natural condition or after dried in oven, it keeps flat and good to be laminated perfectly with other rapid test components.
