Packaging material having good moisture barrier properties from C1S paperboard |
摘要 |
The preparation of packaging material having good moisture barrier properties from a C1S paperboard substrate in a single pass on a printing press is improved by preheating the substrate before application of the moisture barrier coating to the uncoated surface of the substrate. Preheating the substrate improves coating holdout, reduces pinholes and permits the application of a thin film of coating to achieve the desired result.
