The Permeability of Sachets and Pouches

Measuring the permeability of sachets and pouches can be accurately, easily and quickly achieved with our latest permeability meter. It can measure the permeability of both individual materials as well as finished product.

The permeability of sachets and seals can vary greatly from values predicted from the materials used – with some manufacturing processes reducing permeability to just 25% of the original value.

Our meter offers highly automated computerised control and is capable of coping with several samples at a time, giving results that can be accurate to a few part per million (with some samples a few parts per hundred million). Where required, flow rates considerably in excess of 3,000g/m²/day can also be measured using alternative techniques.

Versaperm also offers a laboratory testing service for companies who test too few samples to make the purchase of equipment viable. Where required by legislation our testing service also includes gravimetric testing of sachets, pouches and other products/materials.

Sachet are commonly used to package a wide range of products - from liquids, pastes, gels, granules, tissues to a variety of solid items.. Product types are extremely diverse, including cosmetics and pharmaceutical products through to automotive parts, tissues, candles, foods and toys.
