We report on an investigation of the infrared properties of planetary nebulae (PNe) with H-rich central stars and with [WR]-type central stars ([WR] PNe) which certainly are H-poor. The infrared radiation comes mainly from the layers expelled at the AGB and can reveal the evolutionary history of the two groups.
