A container liner, shelf liner or drawer liner that will absorb liquids spilled or leaked into a container or onto a shelf or drawer. The liner is a layered product having a layer which is impervious to liquids and an absorbent layer. The absorbent layer further contains a material which is capable of controlling odors, such as those odors found in refrigerators and waste receptacles. The liner of the present invention provides the benefit of absorbing spills and controlling odors in containers such as refrigerators and waste receptacles.
