It very depends on what type of plastic. Normally it taks hundreds to thousands years.and somtimes forever.
because they take a long time to rot and decay
The rate of decay for a lollipop wrapper depends on the construction of a wrapper. If it is paper, it will decay in a few months. Plastic may take centuries. Foil will take about 25 years.

Nylon is a synthetic polymer that is not easily biodegradable. It can take hundreds of years to fully decay in the environment, contributing to plastic pollution. Recycling and proper disposal are important to mitigate the impact of nylon waste on the environment.
Sheet metal can take hundreds to thousands of years to decay, depending on factors such as the environment and the type of metal.

Nuclear waste can take thousands to millions of years to decay completely, depending on the type of radioactive material.
Plastic cups can take hundreds of years to decay, as they are made from synthetic materials that are not biodegradable. Instead of breaking down into natural components like organic materials, plastic cups break into smaller pieces called microplastics that can harm the environment and wildlife. Recycling plastic cups is a more sustainable option to reduce their environmental impact.
Cellophane can take several months to a few years to decay, depending on environmental conditions such as moisture and temperature. Unlike plastic, which can take hundreds of years to break down, cellophane is made from natural materials and is more biodegradable. However, its decomposition process can still be slow in certain conditions. Proper disposal and composting can help speed up its breakdown.
The fustion will take place so long as the decay time for isotopes which is ...not stable is over.

It will take two half-lives or about 60.34 years for three-fourths of a Cs-137 sample to decay.
