常见问题解答
什么是PP中空板？
PP中空板（也称为双壁聚丙烯板或波纹塑料板）是一种由两层平整的PP表层通过内部肋条连接而成的轻质板材。 这种中空结构在重量极轻的情况下仍能提供高刚度——4毫米厚的板材重量仅约0.6千克/平方米，但其刚度却可与重量大得多的实心材料相媲美。.
PP中空板的标准尺寸是多少？
The most common standard size is 4×8 ft (1220 × 2440 mm). PPBOXY also supplies custom-cut sheets to your exact dimensions. Common widths include 1000 mm, 1220 mm, and 1560 mm, with lengths up to 3000 mm. Custom sizes are available with a minimum order of 100 sheets.
PP中空板可以在户外使用吗？
Yes. Standard PP hollow sheets include UV stabilizers that provide 2–3 years of outdoor life without significant fading or embrittlement. For permanent outdoor installations (signs, building cladding), we offer extended-life UV formulations rated for 5+ years. The material is also waterproof and will not rot, swell, or delaminate in rain or snow.
如何切割和加工PP中空板？
PP hollow sheets can be cut with a utility knife (score and snap for straight cuts), circular saw, or CNC router. They can be scored and folded for box-making, drilled for fasteners, and welded using hot air or ultrasonic welding. For curved shapes, sheets up to 4 mm can be cold-bent; thicker sheets may require thermoforming.
我应该使用多厚的PP中空板？
ApplicationRecommended ThicknessYard signs, temporary signage3–4 mmPackaging boxes, dividers2–4 mmConstruction wall/floor protection4–6 mmAutomotive interior panels3–5 mmPermanent outdoor signage5–8 mmLoad-bearing or structural uses8–10 mm
When in doubt, contact our team — we will recommend the optimal thickness based on your specific application and loading requirements.
PP中空板与瓦楞纸板有什么区别？
PP hollow sheets are waterproof (cardboard absorbs moisture and collapses), 20–30× more durable (cardboard degrades after 1–3 uses), and 100% reusable (cardboard is single-use in most applications). While PP sheets cost 3–5× more upfront, the cost-per-use drops significantly after multiple cycles — making PP the more economical choice for reusable packaging, outdoor signage, and multi-trip logistics.
Are PP hollow sheets food-safe?
Virgin-grade PP hollow sheets comply with FDA 21 CFR 177.1520 for indirect food contact and EU Regulation EC 1935/2004 for food-contact materials. They are suitable for food packaging dividers, beverage layer pads, and agricultural produce trays. For direct food contact applications, specify food-grade virgin PP and request certification documentation with your order.
Can PP hollow sheets be printed on?
Yes. PP hollow sheets accept CMYK digital printing, screen printing, and UV flatbed printing directly onto the surface — no priming required. Full-surface, edge-to-edge printing is possible on both single and double sides. Minimum order for custom-printed sheets is 200 pieces. Standard lead time is 7–10 working days.
