What Materials Are Used for Food-Grade Paper Bags
Food-grade paper is commonly used for packaging food to maintain freshness, hygiene, and safety.
Core Material Types for Food-Grade Paper Bags
Food-grade paper bags must meet requirements for safety, non-toxicity, and oil resistance. Common materials include:
1. Kraft Paper:
● Characteristics: Natural brown color, high tensile strength, recyclable and biodegradable.
● Applications: Bread bags, dried fruit packaging, and other dry foods.
● Certification: Must pass FDA (US) or GB 4806.8-2016 (China) food contact material standards.
2. Greaseproof Paper:
● Characteristics: Surface coated with food-grade silicone oil or fluorocarbon resin for oil resistance.
● Applications: High-oil scenarios like fried foods and hamburger packaging.
3. Laminated Paper:
● Characteristics: Paper base + PE/PLA laminated layer, waterproof and moisture-resistant.
Subtypes:
● PE Laminated (Polyethylene): Low cost but non-degradable.
● PLA Laminated (Polylactic Acid): Derived from corn starch, compostable and biodegradable.
4. White Cardstock:
● Characteristics: Smooth and flat surface with excellent printability, commonly used for premium food gift boxes.
● Grammage Range: Typically 200–400 g/m² (refer to Paper Products Industry Standard).
● Summary: Food-grade paper bag materials offer diverse options. Selection requires balancing safety, functionality, and environmental sustainability while monitoring emerging technologies to meet differentiated needs.
