What is the difference between industrial grade polyethylene (PE) plastic bags and ordinary grade?

Industrial grade polyethylene (PE) plastic bags differ significantly from ordinary grade plastic bags in several aspects. Here is a detailed introduction and explanation of these differences:
Material quality
Industrial grade: Industrial grade polyethylene plastic bags usually use higher grade polyethylene materials, which have better chemical resistance, temperature resistance and mechanical strength. They can withstand more severe industrial environments and heavier loads.
Ordinary grade: Ordinary grade plastic bags may use lower cost polyethylene materials, which may not be as good as industrial grade materials in terms of chemical resistance, temperature resistance and mechanical strength.
Durability
Industrial grade: Due to the use of higher quality materials, industrial grade plastic bags are usually more durable, can withstand frequent use and handling, and are suitable for repeated use.
Ordinary grade: Ordinary grade plastic bags may be more easily damaged, especially when subjected to heavier items or frequent use.
Temperature resistance
Industrial grade: Industrial grade plastic bags can withstand a wider range of temperatures, from very low temperatures to higher temperatures, which makes them suitable for use in temperature environments.
Ordinary: Ordinary plastic bags may only be used within a narrow temperature range and are not suitable for high or low temperature environments.
Sealing
Industrial: Industrial plastic bags generally have better sealing properties, which can ensure the safety and integrity of the contents of the package and prevent leakage or contamination.
Ordinary: Ordinary plastic bags may not be as good as industrial ones in terms of sealing and may be more prone to leakage or breakage.
Customization
Industrial: Industrial plastic bags tend to offer more customization options, including size, thickness, color, printing, and special features (such as anti-static, UV resistance, etc.) to meet the needs of specific industrial applications.
Ordinary: Ordinary plastic bags may be limited in customization and are usually only available in standard sizes and colors.
Safety standards
Industrial: Industrial plastic bags need to meet more stringent safety and compliance standards, including food safety, environmental safety, and industrial safety standards.
Ordinary: Ordinary plastic bags may only need to meet basic safety standards and may not be suitable for all industrial applications.
Cost
Industrial: Due to the use of higher quality materials and more complex production processes, the cost of industrial plastic bags is generally higher than that of ordinary plastic bags.
Ordinary grade: Ordinary grade plastic bags are usually cheaper due to their lower production costs.
Application areas
Industrial grade: Industrial grade plastic bags are widely used in chemical, construction, agriculture, automobile, electronics and other industries to package heavy, easily contaminated or items that require special protection.
Ordinary grade: Ordinary grade plastic bags are often used in daily life and commercial retail, such as supermarket shopping bags, garbage bags, etc.
In summary, industrial grade polyethylene plastic packaging bags are better to ordinary grade plastic bags in terms of material quality, durability, temperature resistance, sealing, customization, safety standards and cost. These characteristics make industrial grade plastic bags more suitable for use in demanding industrial environments.
