PP hollow grid sheet is a lightweight twin-wall product with parallel internal flutes between flat skins. A production-line proposal should begin with the sheet structure, dimensions, weight and converting process rather than a generic board-machine model.
Typical downstream uses can include protective packaging, layer pads, signs, dividers and reusable containers. Each use can require different surface treatment, color, printing, cutting, creasing or welding preparation.
Typical equipment scope
- PP material feeding, dosing and preparation equipment when required
- Extruder and hollow-sheet die
- Calibration, cooling and forming section
- Haul-off and surface-protective handling
- Edge trimming and scrap collection
- Cutting, stacking or conveying equipment
- Optional corona treatment, printing or converting interfaces
- Crusher or material-return equipment when included
The quotation should identify included die components, calibration parts, treatment equipment and converting scope separately.
Information needed for a proposal
- PP resin grade and recycled-content plan
- Twin-wall flute drawing or accepted sample
- Sheet width, thickness and finished length
- Required board weight per area or accepted sample weight
- Color and surface requirements
- Printing, corona treatment, cutting, creasing or welding needs
- Flat-sheet, stacked or converted-product delivery format
- Edge-trim and rejected-sheet reuse plan
- Target production rate
- Voltage, cooling-water, compressed-air and workshop conditions
Frequently asked questions
Is PP hollow grid sheet the same as solid sheet?
No. The parallel internal flute structure changes the die, calibration and product inspection requirements. Supply a cut-edge sample or structural drawing.
Can recycled PP be included?
Describe the source, preparation, expected proportion and required product appearance. Material consistency and contamination controls must be reviewed for the intended sheet.
Can converting equipment be supplied with the line?
List each required operation and the finished package design. Printing, cutting, creasing, welding and box making are separate processes and should be scoped individually.
