Claims (13)

1. A film comprising:

an ethylene blocking agent complex comprising the product of an ethylene blocking agent selected from the group consisting of cyclopropene, 3,3-dimethycyclopropene, methylenecyclopropane and derivatives thereof and a host selected from the group consisting of cyclodextrins and crown ethers; and

at least one water-soluble polymer selected from the group consisting of methylcellulose, propylcellulose, ethylcellulose and hydroxyethylcellulose;

wherein the ethylene blocking agent complex and the at least one water-soluble polymer are intermingled.

5. The composition of claim 1 , further comprising a water-insoluble polymer.

6. The composition of claim 1 , wherein the ethylene blocking agent complex comprises from 0.05 to 0.5 percent by weight ethylene blocking agent.

7. The composition of claim 1 , wherein a ratio of water-soluble polymer to ethylene blocking agent complex ranges from 20: 1 to 1 :3 by weight.

8. The composition of claim 5 , wherein a ratio of water-soluble polymer to water-insoluble polymer ranges from 50:1 to 1:50.
