What is the GSM of HDPE?

GSM, or grams per square meter, is a key measure of the density and thickness of materials, including HDPE (High-Density Polyethylene) tarpaulins. The GSM of HDPE tarpaulins can vary widely depending on the intended application and required durability. At Welpack Industries Pvt. Ltd., we offer a range of HDPE tarpaulins with different GSM ratings to cater to various needs.

GSM Range of HDPE Tarpaulins

HDPE tarpaulins are available in a broad spectrum of GSM values, each suitable for different applications:

  • 90GSM and 95GSM HDPE Tarpaulin:
    • Characteristics: Lightweight and easy to handle.
    • Best For: Temporary coverings, light-duty applications such as protecting furniture or seasonal agricultural use.
  • 120GSM HDPE Tarpaulin:
    • Characteristics: Still lightweight but offers better durability than 90GSM.
    • Best For: General-purpose covers, protecting garden furniture, and moderate weather protection.
  • 150GSM HDPE Tarpaulin:
    • Characteristics: Balanced durability and flexibility.
    • Best For: Medium-duty applications like covering market stalls, event spaces, and temporary roofing.
  • 170GSM HDPE Tarpaulin:
    • Characteristics: Heavier and more robust, providing better protection against harsher conditions.
    • Best For: Applications that require stronger material but still need some flexibility, like construction site covers.
  • 200GSM HDPE Tarpaulin:
    • Characteristics: Durable and suitable for more demanding tasks.
    • Best For: Construction sites, long-term outdoor storage, and as a base for outdoor events.
  • 250GSM HDPE Tarpaulin:
    • Characteristics: Heavy-duty with excellent tear resistance.
    • Best For: Industrial applications, heavy-duty transportation covers, and long-term weather protection.
  • 300GSM to 425GSM HDPE Tarpaulin:
    • Characteristics: The heaviest and most durable options available.
    • Best For: Extreme weather conditions, military uses, large-scale industrial covers, and any application requiring the highest level of durability and protection.

Importance of GSM in HDPE Tarpaulins

The GSM rating of a tarpaulin significantly affects its performance:

  • Durability: Higher GSM tarpaulins are generally more durable and can withstand more wear and tear.
  • Weight: Higher GSM tarpaulins are heavier, which can affect ease of handling and transportation.
  • Protection: Thicker tarpaulins offer better protection against elements such as rain, wind, and UV rays.

Choosing the Right GSM for Your Needs

To select the right GSM for your HDPE tarpaulin, consider the following factors:

  • Application: Determine what you need the tarpaulin for. Light-duty tasks can be managed with lower GSM, while heavy-duty and industrial uses require higher GSM.
  • Environmental Conditions: For exposure to harsh weather, including high winds and heavy rain, a higher GSM tarpaulin will provide better protection and longevity.
  • Frequency of Use: For frequent handling and use, a mid-range GSM (150GSM to 200GSM) provides a balance between durability and ease of use.
  • Budget: Higher GSM tarpaulins are more expensive but offer better durability and longer life, making them cost-effective in the long run.


Understanding the GSM of HDPE tarpaulins is crucial for selecting the right product for your specific needs. Whether you need a lightweight tarpaulin for temporary use or a heavy-duty one for long-term protection, Welpack Industries Pvt. Ltd. offers a wide range of options to meet your requirements.
