Custom printed deli paper represents a specialized segment in the food packaging industry, combining functional performance with branding opportunities. This wax-free, grease-resistant paper is engineered to provide a barrier against oils and fats while maintaining breathability, making it an ideal substrate for wrapping and separating food products. Unlike traditional waxed papers, modern deli paper is typically treated with proprietary coatings that enhance its resistance properties without compromising recyclability or compostability in many cases. The custom printing capability allows businesses to transform a simple functional item into a powerful marketing tool, displaying logos, brand colors, and promotional messages directly on the packaging that interacts with the end consumer.
The performance of custom printed deli paper is defined by a set of precise technical characteristics. Its grease resistance is measured using the Kit Test, with high-quality deli paper typically achieving ratings between 5 and 9 (on a scale of 12), indicating substantial resistance to oil penetration. The basis weight generally ranges from 18 to 28 pounds (30-47 gsm), providing an optimal balance between strength and flexibility. Its porosity (measured in Gurley seconds) ranges from 10-50 seconds/100ml, allowing the paper to "breathe" and prevent moisture buildup that could compromise food texture. The tensile strength in the machine direction is typically between 4.5-7.0 kN/m, ensuring integrity during high-speed wrapping operations. Many premium deli papers also feature heat resistance up to 400°F (204°C) for short durations, making them suitable for use with hot foods.
| Property | Typical Value Range | Test Method |
|---|---|---|
| Basis Weight | 18-28 lbs (30-47 gsm) | TAPPI T410 |
| Grease Resistance (Kit Rating) | 5-9 | TAPPI T559 |
| Tensile Strength (MD) | 4.5-7.0 kN/m | TAPPI T494 |
| Porosity (Gurley) | 10-50 seconds/100ml | TAPPI T460 |
| Heat Resistance | Up to 400°F (204°C) | ASTM D619-06 |
The versatility of custom printed deli paper makes it suitable for numerous applications across the food service and retail sectors:
Sandwich and Burger Wrapping: Its breathability prevents sogginess while containing oils and condiments. Quick-service restaurants with high-volume operations particularly benefit from the combination of functional performance and brand reinforcement.
Butcher and Deli Counter Separation: Used between slices of meat, cheese, and other prepared foods to prevent sticking and facilitate easy separation for consumers. The grease-resistant properties maintain product integrity during refrigeration.
Bakery and Pastry Liners: Provides an attractive presentation for cookies, pastries, and baked goods while absorbing minimal oil from high-fat products. The printable surface allows bakeries to include heating instructions, ingredients, or branding.
Food Truck and Takeaway Packaging: The compact, lightweight nature of deli paper makes it ideal for mobile food operations where space is limited. Custom printing helps build brand recognition for businesses without permanent physical locations.
Specialty Food Retail: Artisanal cheese shops, gourmet markets, and specialty food producers use custom printed deli paper to communicate quality and craftsmanship through sophisticated packaging design.
Catering and Event Services: For buffet setups and boxed meals, deli paper provides functional separation between different food items while maintaining a cohesive branded appearance.
To maintain the performance and print quality of custom printed deli paper, proper storage and handling procedures should be followed:
Temperature and Humidity Control: Store in a climate-controlled environment between 60-75°F (15-24°C) with relative humidity between 40-55%. Extreme conditions can affect the paper's moisture content, potentially causing curling or dimensional changes that impact runnability on automatic wrapping equipment.
Protection from Direct Sunlight: UV exposure can cause fading of printed inks over time. Store printed rolls or stacks in their original packaging until ready for use, and keep away from direct light sources.
Horizontal Storage for Rolls: When storing roll stock, maintain horizontal positioning to prevent deformation. Stacked rolls should not exceed five high to avoid crushing the core or distorting the roll shape.
First-In-First-Out Inventory Management: Rotate stock to ensure older materials are used before newer ones, maintaining optimal performance. While deli paper doesn't have a strict expiration date, long storage periods (beyond 12 months) may affect performance characteristics.
Moisture Barrier Protection: Keep packaging sealed until use to prevent absorption of environmental moisture, which can compromise the grease-resistant coatings and affect performance.
Clean Handling Procedures: Use gloves when handling printed sheets to prevent transfer of oils from skin to the paper surface, which could potentially interfere with the grease-resistant barrier.
The printing process for custom deli paper requires specific considerations to ensure food safety and visual quality. Food-grade inks compliant with FDA regulations (FDA 21 CFR Part 73) must be used for direct food contact applications. Flexographic printing is the most common method, offering high-speed production capabilities and the ability to print on relatively porous substrates. This process can achieve line screens of 100-133 lpi, sufficient for most brand graphics and text elements. For higher-end applications requiring photographic quality, offset printing with UV-cured inks can achieve line screens up to 175 lpi, but requires specially coated deli papers to ensure ink adhesion. Digital printing has emerged as a solution for short runs and variable data applications, though substrate compatibility must be carefully evaluated. The minimum font size for legible text is typically 6 point for sans-serif fonts, and reverse text should be avoided below 8 point to maintain readability.
Modern custom printed deli paper aligns with growing sustainability initiatives in the food service industry. Many varieties are produced from FSC-certified sustainable forestry sources, with some manufacturers offering options containing 20-30% post-consumer recycled content. The absence of wax coatings makes most contemporary deli papers readily recyclable in mixed paper streams, and many are compostable in commercial composting facilities, breaking down within 4-8 weeks under appropriate conditions. The paper's relatively light basis weight contributes to a favorable carbon footprint compared to alternative packaging materials, with life cycle assessments indicating approximately 1.8-2.2 kg CO2 equivalent per kg of paper produced. Water-based coatings and soy-based inks further enhance the environmental profile, reducing VOC emissions during production and disposal.
