Customized plastic bags have a wide range of applications, from food packaging and daily necessities packaging to industrial product packaging, covering almost all industries that require packaging. Different industries have different requirements for plastic bags. For example, food packaging must meet food safety standards to ensure it is non-toxic and harmless; industrial packaging focuses more on load-bearing capacity and durability. Furthermore, with increasingly stringent environmental regulations, customized plastic bags must also meet environmental requirements such as biodegradability and recyclability to reduce their environmental impact.
