If you wish to purchase plastic bags*, garbage bags*, and disposable items like plates*, cups, spoons, containers, straws and chopsticks, you can head on to Kong Wah, which is a stall located on the 1st floor of the Old Town wet market in Jalan Othman, Petaling Jaya.
The stall is located right above the section of the market that sells fish and seafood.
I do try to cut down plastic bags usage in my life but in some situations it can be hard to avoid. For example, I have a garden which I need to sweep the leaves and have the weeds cut periodically and bagged. There are twigs and fallen branches which would easily poke through most garbage bags hence I must get the durable ones. And the stall sells these durable garbage bags in a few sizes which comes in black and yellow colour.
I also go to the meat section where I get meat to cook for my pet dogs- which I would use a durable plastic bag to fill the contents (flimsy plastic bags will sometimes break in between).
Through looking around, I discovered this stall and find their prices to be reasonable so I have been buying from them from time to time. They also have a lot of variety of plastic bags including decorative ones.
As they also sell a lot of disposable containers, many food eateries owners would come and get their supplies from them.
