As a professional food packaging factory focusing on catering packaging solutions, the most common question from global fast-food brands and takeaway chain customers is:
“What makes 80gsm square bottom greaseproof bags more suitable for high-oil food takeaway packaging?”
80gsm square bottom greaseproof paper bags are upgraded thickened catering packaging bags, specially designed for high-oil, high-moisture and heavy-load food scenarios. Based on premium 80gsm thickened food-grade greaseproof paper and integrated square bottom craftsmanship, they feature stronger oil resistance, better toughness and higher load-bearing capacity than 70gsm regular models. They can effectively solve oil leakage, bag body softening and tearing problems during fast-food takeaway delivery, becoming the preferred packaging for medium and high-end catering chain brands.
What Is 80gsm Square Bottom Greaseproof Paper Bag?
An 80gsm square bottom greaseproof paper bag is a heavy-duty food-grade packaging bag for professional catering use. It adopts upgraded 80gsm thickened pure wood pulp greaseproof paper with double-layer anti-oil treatment, which can resist heavy grease, sauce and water vapor penetration. The reinforced square bottom structure is firm and pressure-resistant, not easy to expand or crack when holding heavy food. It supports long-distance takeaway delivery and customized brand printing, fully meeting high-standard commercial catering packaging needs.

Key Features of 80gsm Square Bottom Greaseproof Paper Bags
Upgraded 80gsm Thickness, Strong Toughness & Tear Resistance
Compared with 70gsm lightweight bags, the 80gsm thickened paper has higher stiffness and tensile strength. The bag body is firm and upright, not easy to soften, sag or tear when containing high-oil and heavy food. The reinforced square bottom effectively bears heavy loads without cracking, avoiding food leakage and packaging damage during delivery.
Enhanced Heavy Greaseproof & Sauce Resistant Performance
Adopting advanced food-grade anti-oil coating technology, the paper surface forms a dense and stable protective layer. It can block heavy grease, salad sauce, ketchup and water vapor penetration, keeping the bag outer surface dry and clean. No oil stains penetrate to pollute hands and packaging bags, ensuring hygienic and neat food delivery.
Excellent Printing Effect & Brand Presentation
The thickened paper surface is flat, smooth and highly ink-absorbent, supporting high-definition logo printing, full-color patterns and brand text customization. The printing effect is clear and firm without ink fading or blurring. The neat square bottom shaping improves the overall grade of food packaging, helping catering brands enhance market competitiveness.
Food-Safe & Eco-Friendly for Commercial Use
All raw materials are food-grade compliant, non-toxic, odorless and safe for long-term direct food contact. The product meets EU food safety certification and global green packaging standards, 100% recyclable and degradable. It is a safe and compliant sustainable packaging choice for catering chain commercial use.
