Rigid PVC Films
The use of rigid polyvinyl chloride (PVC pharmaceutical rigid films) as a means of protecting drugs has been established for many years. PVC is used in PTP Al/plastic packaging to provide consumers with a wide range of benefits such as product visibility, barrier and mechanical protection, ease of use and adaptability. Polymer monolayer polyvinyl chloride films are commonly used in less demanding applications
Rigid PVDC Films
In order to provide pharmaceutical products with additional barrier properties; particularly from moisture / oxidation, many enhanced performance protective ingredients can be added as a coating on the polymer films. For e.g. Vinylidene Chloride (PVDC) which provides a high moisture-proof protection.
Typically, 40g, 60g and 90g/m2 of coating weight can lower the water vapor transmission rate (WVTR) from 0.6g/m2 to 0.2g/m2.
With the advent of new drugs and new detection trends (40°C – 75% RH), additional barrier performance requirements have steadily increased.
The development of our new PVDC series products can improve the barrier performance of PVDC, which will have a high barrier to water and oxygen and therefore offers even greater protection for pharmaceuticals. Our super B series PVDC has been able to achieve water vapor barrier properties of less than 0.1g/m2d.
