PP 중공 시트 / Coroplast Sheet for Packaging and Industrial Applications
PP 중공 시트, also called 부식질 시트, corrugated plastic sheet 또는 fluted polypropylene sheet, is a lightweight and reusable plastic sheet made from polypropylene. It is widely used for packaging, 분배기 삽입, 레이어 패드, signs, 바닥 보호, agricultural protection and industrial turnover solutions.
For buyers, the main selection points are sheet thickness, GSM/weight, 크기, 색상, surface treatment, printing requirement, load, reuse frequency and whether special functions such as anti-static, flame-retardant or UV-resistant performance are needed.
PP 중공 시트 란 무엇입니까??
PP hollow sheet is produced with a hollow rib structure. This structure helps the sheet stay lightweight while maintaining stiffness and impact resistance. Compared with paperboard, plywood or solid plastic sheet, PP hollow sheet is easier to clean, moisture-resistant and suitable for repeated use in many packaging and protection scenarios.
Common Applications
- Reusable packaging: 물결 모양 플라스틱 상자, turnover boxes, totes and pallet sleeve systems.
- Divider and layer pad: protection between bottles, cans, 전자 제품, glass, metal parts or automotive components.
- Electronics packaging: anti-static sheet and ESD box material for PCB, connectors and components.
- Advertising and signage: yard signs, display boards, printed panels and temporary signs.
- Floor and surface protection: temporary protection during construction, renovation and logistics handling.
- Agriculture and outdoor use: 나무 경비원, seedling protection and waterproof temporary boards.
Key Specifications Buyers Should Confirm
| Specification | What to Confirm | Why It Matters |
|---|---|---|
| 두께 | Commonly selected according to use, load and stiffness requirement | Affects strength, weight, cost and processing method |
| GSM / weight | Sheet weight per square meter | Helps compare material strength and price more accurately |
| Sheet size | Width, length and tolerance requirement | Determines cutting plan, packing method and material waste |
| 색상 | Natural, 하얀색, 검은색, blue or custom color | Used for identification, branding and application matching |
| Function | Standard, 정전기 방지, flame-retardant or UV-resistant options | Matches electronics, outdoor or safety-related scenarios |
| Processing | 절단, creasing, die-cutting, 인쇄, welding or edge finishing | Turns sheet material into boxes, pads, dividers or signs |
How to Choose the Right PP Hollow Sheet
If the sheet is used for signs or temporary display boards, buyers usually focus on flatness, printing effect, color and outdoor exposure time. If it is used for packaging or turnover, stiffness, load, folding structure and reuse frequency are more important. If it is used for electronics packaging, anti-static performance and surface resistance requirement should be confirmed before production.
PP Hollow Sheet vs Other Packaging Materials
| 재료 | Strength | Moisture Resistance | Reuse | Typical Use |
|---|---|---|---|---|
| PP 중공 시트 | Good stiffness with lightweight structure | Good | Reusable | 포장, dividers, signs, 보호 |
| Paperboard | Limited under moisture or heavy turnover | Low | Usually limited | Disposable packaging |
| Plywood | Strong but heavier | Medium | Reusable in some scenarios | Heavy-duty protection |
| Solid plastic sheet | Strong but heavier and higher material use | Good | Reusable | Rigid panels and special parts |
Custom Processing Options
- Custom sheet size, 두께, GSM and color
- Cut-to-size sheets and die-cut shapes
- Creasing and folding for corrugated plastic boxes
- Divider inserts, knife cards and layer pads
- Printing for signs, 라벨, logos or product information
- 정전기 방지, flame-retardant or UV-resistant options according to project needs
Application Scenarios
PP hollow sheet can be used as a raw sheet material or processed into finished packaging. In electronics factories, it can become anti-static boxes, dividers and layer pads. In logistics and warehousing, it can be used for reusable totes, pallet sleeve boxes and product separation. In advertising, it can be printed into lightweight signs. In construction or renovation, it can protect floors and surfaces from dust, scratches and moisture.
