Custom Printed Wax Paper

Introduction to Custom Printed Wax Paper

Custom printed wax paper is a specialized packaging material that combines the functional benefits of traditional wax paper with customizable printing capabilities. This innovative material features a thin paper base coated with food-grade wax (typically paraffin or soybean wax) and can be printed with high-resolution designs, logos, or branding elements using food-safe inks. The wax coating provides moisture resistance while maintaining the paper's flexibility and breathability.

Key Characteristics with Technical Data

Material Composition

• Base Weight: Typically ranges from 30-50 gsm (grams per square meter)

• Wax Coating: 10-20 microns thickness, with coating weights of 5-12 gsm

• Wax Types: Paraffin (melting point 46-68°C), Soybean (melting point 49-82°C), or blends

Barrier Properties

• Water Vapor Transmission Rate (WVTR): 5-15 g/m²/day at 38°C and 90% RH

• Grease Resistance: Kit rating of 8-12 (ASTM D722)

• Oxygen Transmission Rate (OTR): 150-300 cc/m²/day at 23°C and 0% RH

Printing Specifications

• Print Resolution: Up to 1200 dpi with flexographic or digital printing

• Color Gamut: CMYK + spot colors available, with ΔE ≤ 3 color accuracy

• Ink Adhesion: ≥ 90% as measured by ASTM D3359 cross-hatch test

Physical Properties

• Tensile Strength: 20-40 N/15mm in machine direction (MD), 15-30 N/15mm in cross direction (CD)

• Elongation: 4-8% at break (MD), 6-10% at break (CD)

• Heat Seal Strength: 200-500 g/25mm at 100-130°C sealing temperature

Primary Application Scenarios

Proper Maintenance and Handling

Storage Conditions

To maintain optimal performance of custom printed wax paper:

• Store in a cool, dry environment between 15-25°C (59-77°F)

• Maintain relative humidity at 40-60% to prevent wax bloom

• Keep away from direct sunlight to prevent ink fading and wax softening

• Store rolls horizontally or vertically on appropriate racks to prevent deformation

• Maintain inventory rotation (FIFO system) as shelf life is typically 12-18 months

Handling Precautions

• Use clean, dry hands or cotton gloves when handling to prevent fingerprints on printed surfaces

• Avoid sharp objects that could puncture the wax layer

• When unrolling, maintain proper tension (2-5 N/cm) to prevent stretching or tearing

• For printed designs, handle with care to prevent ink smudging during the first 24-48 hours after production

Cleaning Methods

While wax paper is generally not designed for reuse, certain applications may require cleaning:

• For light surface dust, use a soft, dry microfiber cloth

• For grease spots, gently dab (don't rub) with a cloth moistened with food-grade alcohol (70% isopropyl)

• Never use abrasive cleaners or solvents that could dissolve the wax coating

• Avoid water immersion as this can cause delamination of the wax layer

Temperature Considerations

• For heat sealing, maintain temperatures between 100-130°C (212-266°F)

• Avoid prolonged exposure above 80°C (176°F) to prevent wax migration

• In cold environments, allow material to acclimate for 2-4 hours before use to prevent brittleness

• For microwave use, limit to 30-second intervals with food items
