Biaxially oriented polypropylene film

1)Common thickness:20um、30um、40um、

2)The biggest advantage, the most outstanding features: good transparency, good stiffness (hardness);

3)Second advantage: good barrier water performance, as a printing material, its water barrier is better than PET material;

4) The biggest disadvantage: it can't be heat sealed, so it can only be used as the outermost layer of printing material or a bag (roll film);

5)Second disadvantage: the performance of blocking oxygen is slightly worse than PET, that is, the fragrance is not as good as PET;

6)The suitable temperature is -40 ° C ~ 120 ° C, the melting point is 165 ° C, can not withstand too high temperature, so when the material is used as a printing material, if it is an automatic packaging machine, it is not suitable, it will affect the packaging speed and packaging effect (not High temperature resistance, wrinkle when sealing.)

7)In addition to the automatic packaging machine, it is best not to choose this material as the printing material. Most products with low barrier requirements can be selected as the printing material. Such as dried fruit, melon seeds, candied fruit, biscuits, Shaqima and other packaging.
