Low pressure chamber

Differences in (atmospheric) pressure during transport do not only occur in planes. The pressure in the room can also change during truck transport, for instance in the mountains. Especially airtight packagings are affected by changes in atmospheric pressure.

A low pressure test has been developed to simulate changes in pressure in order to test whether the packaging can withstand this, and is therefore able to protect the product properly.

Airtight packaging

The low pressure test is usually performed for airtight packagings that are transported through the air or over mountains. The packaged product is placed in the low pressure chamber and the atmospheric pressure is subsequently reduced at a predetermined speed. The resulting pressure is often maintained for 1 hour. Subsequently, the atmospheric pressure is returned to a normal level. During and after testing, the packaging, and if possible the product, is inspected in terms of possible influences of the low pressure test.
