Sunpack sheets (corrugated polypropylene) offer an economical and durable solution for short-to-medium term signage needs. These lightweight yet sturdy sheets resist moisture, chemicals, and impact - making them a top choice for outdoor event signage, real estate boards, election campaign materials, and directional signs. PrintsWallah delivers high-resolution digital printing on sunpack sheets in custom sizes, ensuring vibrant colours and sharp text that grab attention.
Sunpack sheets, also known as corrugated polypropylene or PP flute boards, are among the most versatile and cost-effective signage materials available in India today. Made from polypropylene copolymer resin, these sheets feature a twin-wall fluted structure that provides exceptional rigidity while remaining incredibly lightweight -typically weighing just 300-900 grams per square meter depending on thickness. This unique construction makes sunpack sheets ideal for temporary to semi-permanent signage applications where durability, weather resistance, and affordability are key considerations for businesses, event organizers, and property developers.
The manufacturing process of sunpack sheets involves extrusion of polypropylene pellets through a specialized die that creates the characteristic fluted internal structure. This twin-wall design traps air between two flat surfaces, creating natural insulation and impact resistance. The sheets are chemically inert, resistant to moisture, oils, and most household chemicals, making them suitable for both indoor and outdoor applications. In India, sunpack sheets are manufactured to IS 14534 standards, with leading manufacturers producing sheets in thicknesses ranging from 2mm to 12mm, though 2mm, 3mm, and 5mm are the most commonly used for printing applications.
No parking board printing represents the single largest use case for sunpack sheets in India. Municipal corporations across all major cities mandate no parking signage for residential societies, commercial complexes, and private properties. A standard no parking board measuring 12×18 inches on 3mm sunpack with UV digital printing costs between ₹80-150 per piece, making it the most economical option compared to metal or acrylic alternatives. PrintsWallah produces over 10,000 no parking boards monthly across our 20 city operations, with custom sizes, bilingual text (Hindi-English or regional language combinations), and reflective options available.
Property signage is another major application where sunpack sheets excel. Real estate developers, brokers, and property owners use sunpack boards for 'For Sale', 'For Rent', 'Under Construction', and directional signage. The standard sizes for property boards range from 2×3 feet to 4×6 feet, printed on 3mm or 5mm sunpack with full-color UV printing. The lightweight nature means these boards can be easily cable-tied to fences, hung from balconies, or mounted on walls without heavy-duty fixtures. At ₹25-45 per square foot for full-color printing, sunpack property signs offer 60-70% cost savings over metal alternatives.
Political campaign and election boards represent a seasonal but massive market for sunpack printing in India. During state and national elections, political parties order millions of sunpack boards featuring candidate photos, party symbols, and slogans. Standard election board sizes include 2×3 ft, 3×4 ft, and 4×6 ft, typically on 3mm sunpack with single or double-sided printing. The Election Commission of India permits specific sizes and placement guidelines, and PrintsWallah ensures all political signage complies with Model Code of Conduct regulations. Bulk orders of 500+ boards qualify for special pricing starting at ₹18 per square foot.
COVID-19 safety signage created an unprecedented demand surge for sunpack printing starting in 2020. Social distancing markers, mask mandatory signs, hand sanitizer station boards, temperature check point signs, and capacity limit notices were required by every office, shop, restaurant, and public building. Even today, many establishments continue to display these signs. Standard COVID safety sign sets of 10 boards on 3mm sunpack with lamination are available at ₹800-1200 per set. This application demonstrated sunpack's unique advantage -rapid production turnaround (same-day possible) at minimal cost.
For outdoor durability, sunpack sheets can be enhanced with UV-resistant lamination that extends their lifespan from 3-6 months to 12-18 months in direct sunlight. The addition of UV lamination adds approximately ₹5-8 per square foot to the base printing cost but significantly improves color retention and weather resistance. For permanent outdoor applications lasting beyond 18 months, we recommend transitioning to sunboard or ACP materials, but for cost-effective temporary to semi-permanent signage, sunpack remains unbeatable in the Indian market.
PrintsWallah uses state-of-the-art UV flatbed printers capable of printing directly onto sunpack sheets up to 8×4 feet in a single pass. Our Konica Minolta and Ricoh UV printers deliver 1440 DPI resolution with CMYK+White ink configuration, enabling vibrant full-color graphics with excellent opacity even on colored or transparent sunpack sheets. Production capacity exceeds 2,000 square feet per hour per machine, enabling same-day dispatch for orders placed before 2 PM across all 20 cities.
