21g Waxed Paper Medium Light Weight for Hamburger Wraps and Sandwich Bags

This 21 g/㎡ waxed paper is the standard choice for fast-food and quick-service restaurant packaging, commonly used for hamburger wraps, sandwich bags, and food tray liners. The glossy side provides excellent grease resistance, while the semi-transparent appearance (70-80% transparency) allows the food to be partially visible. Compliant with international food safety standards and fully recyclable.

Technical Specifications

Process Introduction

Bleached sulfate chemical wood pulp is cooked and refined to a high viscosity state. Heavy sizing with rosin or AKD (0.3-0.5%) creates a strong grease/water barrier while maintaining breathability. The formed web is pressed and dried on multi-cylinder dryers, then supercalendered under high temperature (80-100°C) and pressure (150-250 kN/m) to achieve the characteristic high-gloss surface on both sides. No wax coating is applied – gloss is purely mechanical.
