When reviewing technical specification sheets for commercial paper packaging, one of the most critical metrics you will encounter is GSM. Understanding GSM enables restaurant owners and buyers to select paper bags and containers with appropriate strength for their specific food weight demands.
What is GSM?
GSM stands for Grams per Square Meter. It measures the physical weight and density of paper material independent of dimensions. A higher GSM value signifies a thicker, denser, and stronger sheet of paper.
Common GSM Ranges in Commercial Food Packaging
- 30 - 45 GSM: Lightweight tissue paper, napkin stock, and inner wrapping sheets.
- 60 - 75 GSM: Standard SOS paper bags for lightweight bakery goods, pastries, and sandwiches.
- 80 - 100 GSM: Medium-duty kraft paper shopping bags suitable for 2 to 3 standard takeout containers.
- 110 - 140+ GSM: Heavy-duty kraft paper bags and food boxes engineered for heavy catering pans, family meal deals, and beverage carriers.
Why GSM Matters for Delivery Safety
Selecting an under-specified GSM bag for heavy food orders risks bag bottom failure or handle tearing. Conversely, over-specifying GSM unnecessarily increases packaging unit cost. Working with a knowledgeable wholesale supplier ensures you select the optimal GSM rating for your menu weight profile.
