How to Choose a Cost-Effective PVC Flex Banner? Thickness, Coating, and Durability Guide
PVC Flex Banner (PVC flexible banner) is a widely used material in the advertising industry, suitable for outdoor advertising, event display boards, store signs, and other scenes. However, products of different quality vary greatly in price, durability, and printing effect.
1. Thickness (Gram Weight) - Determines the Strength and Stability of the Banner
The thickness of PVC Flex Banner is usually expressed in gram weight (GSM, grams per square meter), and common specifications are:
- 300-400 GSM: Economical, suitable for short-term indoor activities or temporary promotions.
- 500-600 GSM: Standard outdoor use, good wind resistance, suitable for signs, fences, etc.
- 700+ GSM: High durability, suitable for long-term outdoor advertising or severe weather environments (such as seaside, highway).
Purchase suggestions:
- Short-term activities (1-3 months) → 400-500 GSM
- Long-term outdoor (more than 6 months) → 600 GSM and above
- Strong wind environment → choose thickening (700+ GSM) or edge reinforcement (such as double seam)
2. Coating Type - Affects Weather Resistance and Printing Effect
The coating of PVC Flex Banner determines its UV resistance, waterproof, and anti-fouling capabilities. Common coatings include:
| Coating Type |
Features |
Applicable Scenarios |
| Ordinary PVC Coating |
Basic waterproof, low cost |
Short-term indoor/outdoor activities |
| UV Protective Coating |
Slows down fading, extends service life |
Long-term outdoor advertising (more than 6 months) |
| Matt Coating |
Reduces reflection, improves visual effect |
High-precision image printing (such as photo-level) |
Purchase suggestions:
- Long-term outdoor use → UV anti-ultraviolet coating is a must
- High-precision printing (such as photo-level images) → Matt coating reduces reflection
- Low-cost short-term use → Ordinary PVC coating is sufficient
3. Key Factors of Durability - How to Extend Service Life?
In addition to thickness and coating, the following factors will also affect the durability of PVC Flex Banner:
- Tear Resistance
High-quality PVC banners will add mesh cloth or reinforcement to prevent tearing in strong winds.
Edge perforation + metal grommets can enhance fixation and reduce the risk of damage.
- Printing Technology
Solvent-based ink: low cost, but easy to fade (suitable for short-term use).
UV ink: long-lasting color, UV resistance (suitable for long-term outdoor use).
Latex ink: environmentally friendly and odorless, suitable for indoor activities.
- Installation Method
Tight installation: reduce wind resistance, prevent wrinkles and wear.
Avoid direct contact with the ground: prevent water accumulation and soil pollution from causing aging of the bottom.
4. Cost-Effective Purchase Strategy
| Usage Scenario |
Recommended Specifications |
Budget Reference |
| Indoor events/short-term promotions |
400 GSM + ordinary coating + solvent-based ink |
Low cost |
| Outdoor signs (more than 6 months) |
600 GSM + UV coating + UV ink |
Medium cost |
| High-speed roads/severe weather |
700+ GSM + UV coating + reinforced edges |
Higher cost |
5. Maintenance and Storage Recommendations
- Cleaning: Wipe with a soft cloth + neutral detergent to avoid scratches from a hard brush.
- Storage: Roll up for storage to avoid folding that may cause creases and cracks.
- Repair: Minor damage can be repaired with PVC glue or special patches.
