With so many different types of garbage bags on the market, it can be difficult to select the ones that are most suited to your needs. As the leading plastic bags supplier Penang, we constantly promise that our plastic bags are constructed of eco-friendly materials with high durability and density, and that they can withstand a certain degree of abuse. For example, have a look at our (HDPE) high-density polyethylene. They are created by exposing high molecular density resins to low pressures, resulting in densely packed molecules. Because of their great density, plastic bags may be stretched to carry a higher weight.
