cycloolefin polymer bottle water vapor transmission rate

Carrie May 19,2019 Share this post:

Cycloolefin polymer bottle is a kind of exclusive packaging for biologic products and anti-tumor drugs, but it is rare in domestic COP packaging. In the "14th Five-Year Plan" of China, the pharmaceutical industry has made it important to strengthen the key support and policy support for anti-tumor drugs, generic drugs, generic drugs, and high-end biological products.

Among them, the most widely used cycloolefin polymer in medical packaging is its low water vapor transmission rate. The water vapor transmission rate actually contains two meanings of water vapor permeation and water vapor transmission coefficient. These two meanings also have certain meanings, but they can all be used to indicate that water vapor is transmitted through a certain material. ability. The amount of water vapor permeation indicates the weight of the water vapor permeating material at a certain temperature and humidity for a certain period of time. The water vapor transmission rate is a standard value of the water vapor transmission amount converted by the coefficient, and corresponds to a standard unit for comparison between different test results.

The low water vapor transmission rate of COP bottle is one of the characteristics of COP as a pharmaceutical packaging. It does not produce flakes as an injection container, can be stored under low temperature or liquid nitrogen environment and has strong stability, and the light transmittance is as high as 92%.
