absorb

 [ab-sorb´]
1. to take in or assimilate, as to take up substances into or across tissues, e.g., the skin or intestine.
2. to stop particles of radiation energy so that their energy is totally transferred to the absorbing material.
3. to retain specific wavelengths of radiation incident upon a substance, either raising its temperature or changing the energy state of its molecules.

(ab-sōrb'), Do not confuse this word with adsorb.
1. To take in by absorption.
2. To reduce the intensity of transmitted light.

Joe added: "It is great news that we can now offer our customers trays with a PPI absorber. This provides a number of benefits for producers and retailers and we have a strong expectation that the absorber will reduce wastage and extend shelf life, which is a major focus area for retailers at the moment."
