31g Waxed Paper Heavy Medium for Fruit Preservation and Deli Meat Wrapping

Preferred for applications requiring higher tear strength, 31 g/㎡ waxed paper is another common heavy-medium grade (alongside 30g and 24g). It excels in fruit preservation wrapping, deli meat interleaving, and block cheese protection. The glossy surface resists moisture penetration, while the semi-transparent design allows easy product identification. Fully food-grade and compatible with automated food packaging lines.

Technical Specifications

Process Introduction

Similar core process to 30g with enhanced fiber refining and a slightly higher proportion of long-fiber softwood pulp. Extended beating time increases fiber-to-fiber bonding, resulting in higher tensile strength (≥4.8 kN/m MD) and tear resistance (≥650 mN). Supercalendering parameters (temperature, pressure, and roll speed) are optimized to maintain gloss while preserving structural integrity at this grammage.

Uses & Distinguishing Features

• Fruit Preservation Wrapping – Wraps individual fruits (apples, pears, citrus) to extend shelf life; breathable yet moisture-resistant.

• Deli Meat Interleaving – Separates slices of ham, turkey, and roast beef to prevent sticking.

• Cheese Wrapping – Protects block cheese from drying and absorbing fridge odors.

• Nuts and Snacks Packaging – Inner wrap for premium dried fruit and nut mixes.

Why Choose This Paper

31g offers the sweet spot for food preservation – strong enough to withstand handling yet lightweight enough for cost-effective daily use.
