Most plastics break down more quickly when exposed to sunlight than when buried. The exact time will depend on the type of thickness of the plastic. Some plastics are being made now that breakdown in about 6 months, others may take 10 years or more.
Plastic straws, can take a century or two to degrade in landfills. http://eatingupgreensboro.blogspot.com/feeds/posts/default

The bag itself will take centuries if not longer to break down as it is a layered metalized plastic material.
Yes, but it will take about 500 to 1000 years.
It takes depends on the type of plastic, but no one is certain how long any type of plastic takes to break down. Many early plastic toys from the 60's are beginning to break down significantly. However, clear water bottles like Dasini and most other brands use PET. PET is a relatively modern plastic so there is little information on its degradation. In any case it takes about 1 week for a water bottle to break down with recycling it .
Plastic never decomposes. It will eventually break down into tiny fragments of plastic which can be eaten accidentally by insects, animals and birds.
forever.....
