1. Production Process
The factory typically starts with the procurement of raw materials, mainly different types of plastics like polyethylene. Machines are used to melt and shape the plastic into the form of bags. This may involve extrusion processes where the plastic is forced through a die to create the desired shape and thickness.

2. Quality Control
Quality is crucial. Workers and automated systems check for defects such as holes, improper sealing, or inconsistent thickness. Only bags that meet the set quality standards are packaged for distribution.

3. Environmental Considerations
In modern times, many plastic bags factories are also exploring ways to make their products more environmentally friendly. This could include using biodegradable plastics or reducing the overall thickness of bags to use less material.

4. Market Reach
These factories supply plastic bags to a wide range of customers, from small local stores to large supermarket chains. Their products are used for various purposes, such as carrying groceries or packaging small items.
