Characteristics and advantages of PS plastic sheet
| Characteristics | PS (polystyrene) sheet | Matching the needs of seedling trays |
| Thickness range | 0.2-2mm (customizable) | 0.5-1.5mm is the most commonly used, taking into account both strength and lightness (trays need to bear seedlings + soil) |
| Weather resistance | Resistant to low temperatures (-20℃~60℃), suitable for greenhouse/outdoor use | Adapted to early spring seedling cultivation or environments with large temperature differences |
| Rigidity/impact resistance | High rigidity, excellent bending strength, but brittleness is higher than PP | Need to cooperate with rib design (mold optimization during thermoforming) |
| Thermoforming performance | Heat deformation temperature 70-90℃, easy to blister mold | Rapid prototyping (3-5 seconds/mold), yield rate > 95% |
| Environmental protection | Recyclable (needs to be sorted and processed), some models are degradable (such as adding starch modification) | In line with the trend of sustainable agricultural development |

Advantages of PS sheet
Excellent thermoforming performance: PS material is easy to soften after heating, suitable for various thermoforming equipment, fast molding speed and high efficiency.
Lightweight and high strength: The material is light, easy to carry and stack, and has good support.
Environmentally friendly and recyclable: PS material can be recycled and reused, in line with the requirements of sustainable development.
Smooth surface, waterproof and moisture-proof: effectively prevent moisture penetration and protect the root environment of seedlings.
Obvious cost advantage: Compared with other materials, PS is more competitively priced and suitable for mass production.
Application field
- Greenhouse seedling tray
- Transplanting tray
- Flower nursery tray
- Hydroponic cultivation tray
- Agricultural disposable plastic container



Compared with PP sheet
| Application scenario | PS sheet adaptability | Compared with PP sheet |
| Short-term seedling cultivation (≤3 months) | Low cost, fast molding | PP price is 10%-15% higher |
| Multi-season reuse | High UV resistance model (anti-aging) | PP has better weather resistance |
| Automated transplanting | High tray dimensional stability (PS shrinkage rate <0.5%) | PP is easy to deform |
