Transparency Measurement Of Plastic Sheet And Film

Light transmission property of the plastic films and rigid plastics are quite difficult to measure and define.

Transparency measurement of plastic sheet and film.

A transparency meter also called a clarity meter is an instrument used to measure the transparency of an object. Hazemeters and spectrophotometers are used to measure the level of haze light transmitting and light scattering properties of transparent materials. Plastic sheets and film are polymers that supply material for injection molding machining packaging construction electronics signs and other applications. Available methods for testing the transparency of plastic sheet and film have been found inadequate as regards the correlation between measurement and visual observation.

A mil is 1 1000th of an inch. Looking to measure the thickness and variability of plastic film. Haze measures the milkiness of the material film or sheet. As per the current terminology the materials comprise with the terms such as clarity total transmittance transparency diffuse transmittance see through resolution distance opacity turbidity haze translucency hiding power etc.

These materials resist corrosion and provide electrical insulation. A newly developed procedure based on the determination of light transmission within a very small angle gives good correlation. A newly developed procedure based on the determination of light. Transparency refers to the optical distinctness with which an object can be seen when viewed through plastic film sheet glass etc in the manufacture of sheeting film or glass the quantitative assessment of transparency is just as important as that of haze.

You can also learn more about measuring plastic film thickness and variability in our article how to measure plastic film. 1 1 this test method covers the measurement of the transparency of plastic sheeting in terms of regular transmittance t r although generally applicable to any translucent or transparent material it is principally intended for use with nominally clear and colorless thin sheeting. Plastic film is thinner and more flexible than plastic sheets and is often transparent or translucent. All plastics have some degree of light scattering or transmission loss which is usually measured by astm d1003.
