A Quick Guide to Paper Weight for Packaging"},"content":{"rendered":"<p>When you\u2019re choosing custom packaging, you might see the term <strong>GSM<\/strong> pop up here and there. GSM stands for <strong>grams per square meter<\/strong> \u2014 it\u2019s a measurement of how much a sheet of paper weighs, which directly affects how thick, sturdy, and opaque it feels.<\/p><p>But here\u2019s the thing: <strong>GSM is not the only factor<\/strong> that determines how your packaging looks and performs. The type of material, coatings, and even the intended use all matter just as much. At <strong>Fusenpack<\/strong>, we select the paper weight and finish for each product based on its function \u2014 so you get packaging that not only looks great but works perfectly in real-world conditions.<\/p><div style=\"height:24px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div><h2 class=\"wp-block-heading\">What Is GSM and Why It Matters in Packaging<\/h2><p>Think of GSM as the \u201cweight class\u201d of your paper. A higher GSM number usually means thicker and denser paper, which tends to be more durable. Lower GSM means the paper is lighter and more flexible.<\/p><ul><li><strong>Low GSM (below 50gsm)<\/strong> \u2013 Thin and lightweight, ideal for wrapping or layering without adding bulk.<\/li>\n\n<li><strong>Medium<\/strong><strong> GSM (50\u2013100gsm)<\/strong> \u2013 Versatile, balancing strength with flexibility, often used for paper bags or protective wraps.<\/li>\n\n<li><strong>High GSM (above 100gsm)<\/strong> \u2013 Sturdy and substantial, suitable for premium bags, covers, or products that need extra structure.<\/li><\/ul><p>However, GSM alone doesn\u2019t tell the full story \u2014 a coated 50gsm greaseproof sheet can be more functional for wrapping oily food than a plain 80gsm sheet. That\u2019s why our product selection is based on <strong>material + weight + intended use<\/strong>.<\/p><figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/www.fusenpack.com\/blog\/wp-content\/uploads\/2025\/08\/what-is-gsm-and-why-it-matters-in-packaging-1024x576.webp\" alt=\"what-is-gsm-and-why-it-matters-in-packaging\" class=\"wp-image-5913\" srcset=\"https:\/\/www.fusenpack.com\/blog\/wp-content\/uploads\/2025\/08\/what-is-gsm-and-why-it-matters-in-packaging-1024x576.webp 1024w, https:\/\/www.fusenpack.com\/blog\/wp-content\/uploads\/2025\/08\/what-is-gsm-and-why-it-matters-in-packaging-500x281.webp 500w, https:\/\/www.fusenpack.com\/blog\/wp-content\/uploads\/2025\/08\/what-is-gsm-and-why-it-matters-in-packaging-768x432.webp 768w, https:\/\/www.fusenpack.com\/blog\/wp-content\/uploads\/2025\/08\/what-is-gsm-and-why-it-matters-in-packaging-1536x864.webp 1536w, https:\/\/www.fusenpack.com\/blog\/wp-content\/uploads\/2025\/08\/what-is-gsm-and-why-it-matters-in-packaging-600x337.webp 600w, https:\/\/www.fusenpack.com\/blog\/wp-content\/uploads\/2025\/08\/what-is-gsm-and-why-it-matters-in-packaging.webp 2001w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure><div style=\"height:24px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div><h2 class=\"wp-block-heading\">How Material and Coating Affect Performance<\/h2><p>Two papers with the same GSM can feel and behave very differently. Factors like <strong>fiber type<\/strong>, <strong>surface finish<\/strong>, and <strong>special coatings<\/strong> can completely change the experience.<\/p><ul><li><strong>Fiber type<\/strong> \u2013 Virgin wood pulp offers a cleaner, smoother surface compared to recycled paper.<\/li>\n\n<li><strong>Coatings<\/strong> \u2013 PE (polyethylene) coatings create moisture and grease resistance for food packaging.<\/li>\n\n<li><strong>Surface texture<\/strong> \u2013 Kraft paper has a natural, rustic look, while smooth finishes give a premium touch.<\/li><\/ul><p>At Fusenpack, we combine these elements to match the unique needs of every product category \u2014 whether it\u2019s preventing grease stains, supporting heavy contents, or showcasing a custom print.<\/p><div style=\"height:24px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div><h2 class=\"wp-block-heading\">Fusenpack Product Examples and Their Paper Characteristics<\/h2><p>At Fusenpack, we use different types of paper to match the needs of various products \u2014 not because we offer GSM choices, but because every design requires the right balance of thickness, durability, and feel.<\/p><p>For instance, our <strong><a href=\"https:\/\/www.fusenpack.com\/product\/custom-deli-paper_3178bd06-e33c-43d0-86e0-180d88f90153\">custom deli paper<\/a><\/strong> is made from lightweight 36g greaseproof paper, which keeps food fresh while allowing it to fold easily around wraps and sandwiches.
