A biodegradable polymer usable in fishing gear and that biodegrades in aquatic environments. The polymer includes a polymer backbone that has monomeric units that are susceptible to hydrolytic degradation, and a plurality of pH responsive moieties. Each pH responsive moiety is grafted to a respective one of the monomeric units. The pH responsive moieties are relatively hydrophilic when exposed to an aqueous solution of a pro-biodegradation pH range to facilitate hydrolytic degradation of the monomeric units, and are relatively hydrophobic when removed from the aqueous solution of the pro-biodegradation pH range, to protect the monomeric units from hydrolytic degradation.

A heat-shrinkable polyester film includes at least one polyester material made of at least one polyester forming composition which includes a dibasic carboxylic mixture and a diol mixture. The heat-shrinkable polyester film has a heat shrinkage rate of not lower than 25% in a shrinkage direction, which is measured by immersing the heat-shrinkable polyester film in hot water at 65° C. for 10 seconds. A method for producing the heat-shrinkable polyester film is also disclosed.

Disclosed herein are a heat-shrinkable polyester label film and a preparation method thereof. The label film has a shrinkage force not lower than 5.5 N in at least one shrinkage direction after immersing the heat-shrinkable polyester label film in water at 55° C. for 30 seconds, and a heat shrinkage rate of not lower than 50% in the shrinkage direction after immersing the heat-shrinkable polyester label film in water at 55° C. for 240 seconds.
