PVC flex banner production uses three principal methods: knife coating, calendering and lamination. Each process combines PVC with a supporting fabric in a different way, influencing the surface, light transmission, ink absorption and finished material construction.
KNIFE COATING:
Liquid PVC slurry is applied uniformly to both faces of the base fabric using a series of coating blades. Drying combines the PVC and fabric into an integrated material, followed by cooling to form the finished banner.
The process provides penetration resistance, tensile strength and resistance to peeling. The integrated upper and lower construction can eliminate peeling, and welded joints can be stronger than the material itself. Widths can reach 5m. Complex production processes and expensive equipment contribute to higher prices; this process has been associated mainly with imported products in the Chinese market.
CALENDERING:
PVC powder, liquid plasticizer and other raw materials are thoroughly mixed, then bonded to the base fabric under pressure from high-temperature rollers. The result has good surface flatness and uniform light transmission, making it useful for internally illuminated displays. Equipment limitations generally restrict width to no more than 3m.
LAMINATION:
Upper and lower PVC film layers are heated and pressed around the central reinforcing web by heated rollers, then cooled to form the finished material. This process offers excellent ink absorption and strong color reproduction, supporting large-format inkjet printing. Laminated PVC flex banner has accounted for more than 70% of the Chinese market.
PVC FLEX BANNER APPLICATIONS:
Ultra-thin light boxes and space-limited displays
Applications include wedding photography studios, home and architectural decoration, design and planning institutes, product design centers, and bridge and building projects. Ultra-thin light boxes have an elegant, lightweight construction, generally less than 3cm thick—about one-tenth of the thickness of conventional light boxes. This saves space, simplifies installation and transport, and suits elevators, public passages, shopping malls, supermarkets, subways and stations.
Public, educational and cultural venues
Decorative and promotional projects include exhibition halls, museums, libraries, gymnasiums, art galleries, opera houses, universities, middle schools, vocational schools, hospitals, banks, insurance companies and securities businesses.
Retail and commercial promotion
Uses include conference, exhibition and licensing centers; municipal projects; department stores, supermarket chains and shopping plazas; jewelry and cosmetics shops; beverage, tobacco and alcohol businesses; fast-food and pharmacy chains; stationery, boutique and furniture centers; home-appliance wholesalers and musical-instrument retailers.
Municipal lighting and information displays
Projects include municipal flat lighting, square ground lights, park information, lantern festivals, community bulletin boards, waiting booths, bank self-service withdrawal points, telephone booths, emergency power facilities, building displays, airport access points and subway exits.
Hospitality and leisure decoration
Wall graphics and decoration are used in hotels, guesthouses, restaurants, villas, tea houses, western restaurants, cafes, cake shops, bars, karaoke rooms, dance halls, saunas, beauty salons, fitness rooms and health centers.
FAQ
How is laminated PVC flex banner made?
Heated rollers press upper and lower PVC films around a central reinforcing web. The material is then cooled to create the finished banner construction.
Which process provides a flat surface and uniform light transmission?
Calendering provides these features by bonding mixed PVC material to the base fabric using heated rollers. These characteristics are useful for internally illuminated displays.
What should I specify for a PVC flex banner enquiry?
Provide the printing process, intended display or light-box construction, roll width, weight, finish, quantity and required material properties. Explore PVC laminated flex banner or send your banner fabric requirements for a material discussion.
