PP Industrial Packaging Liners

PP Industrial Packaging Liners are corrugated polypropylene components used for layer separation, internal protection and product positioning in industrial packaging. They are supplied as flat panels or converted liners based on the required packaging structure. Reference thicknesses range from 2 to 12 mm, with sheet widths from 50 to 2400 mm and lengths up to 12000 mm. Finished dimensions, cut-outs, slots, crease lines and liner profiles can follow drawings, samples or dimensional data.

Controlled Separation
The panel creates a defined barrier between products, components or stacked layers. This helps maintain spacing inside boxes, crates, pallets and returnable containers.
Moisture-Resistant Material
PP has low water absorption, making the liner suitable for packaging environments where condensation, humidity or routine cleaning is part of normal handling.
Lightweight Construction
The hollow corrugated structure provides panel rigidity without using a solid plastic section of the same overall thickness. This keeps individual liners practical to handle during packing and unpacking.
Repeatable Conversion
Cutting and creasing produce consistent finished geometries. This is useful when the same liner configuration is required across recurring packaging runs.

Industrial Components
Layer pads and separators keep machined parts, metal components and assemblies apart during storage, handling and transport.
Appliances & Electronics
Internal liners organize housings, panels and components within cartons, crates and reusable containers.
Automotive & Machinery
Separators and protective panels create defined spaces for components inside returnable packaging and transport containers.
Logistics Packaging
Layer pads, box liners and partitions support palletized loads and internal container organization where fixed dimensions are required.

Layer Liners
Flat panels placed between product layers. Panel dimensions follow the container interior, pallet pattern or specified product arrangement.
Box Liners
Panels fitted along the internal surfaces of boxes or containers. Cut geometry follows the available internal space and packaging structure.
Dividers
Partitions create separate areas for individual products or component groups. Cell dimensions are determined by product size and loading arrangement.
Protective Inserts
Shaped panels cover defined contact areas, edges or surfaces. Openings and profiles can follow the geometry of the packaged component.

PP Material
Polypropylene provides a lightweight corrugated sheet with low water absorption and a structure suited to cutting and creasing.
Sheet Thickness
Reference thicknesses range from 2 to 12 mm. Selection depends on product weight, liner dimensions, unsupported span and the required rigidity of the finished panel.
Corrugated Structure
The internal ribs support the panel across its surface. Flute direction should be considered when the liner has long unsupported sections, narrow strips or defined folding positions.

Dimensions
Finished length and width can follow drawings, samples or measured dimensions. Available sheet width ranges from 50 to 2400 mm, with lengths up to 12000 mm.
Cutting & Creasing
Slots, openings, corner profiles and crease lines can be processed according to the finished liner geometry.
Color & Surface
Color can be specified for packaging identification or product classification. Surface requirements can be confirmed according to the intended processing and application.
Drawing-Based Production
A technical drawing can define overall dimensions, cut geometry, hole locations, crease positions and other fit-critical details. Physical samples can also be used as production references.

Flat Sheet
Flat panels are supplied for use as layer separators or for further conversion within an existing packaging process.
Cut-to-Size Liner
Panels are cut to specified length and width for direct placement inside boxes, crates, pallets or transport containers.
Creased Liner
Defined crease positions allow the panel to follow packaging edges or form folded sections within the available internal space.
Shaped Insert
Special cutting patterns accommodate corners, openings, product contours and defined contact areas.

Thickness Check
Sheet thickness is checked against the confirmed production specification before finished processing.
Dimensional Check
Finished length and width are measured against the approved dimensions. Processed parts are checked after cutting and creasing.
Cutting Check
Openings, slots, corners and profiles are reviewed against the drawing or confirmed sample.
Crease Check
Crease positions are checked against the specified geometry to maintain the required folded configuration.

Finished Dimensions
Provide the required length, width and thickness of the completed liner.
Packaging Layout
Specify the internal container dimensions, product dimensions and required separation arrangement.
Processing Requirements
List openings, slots, cut shapes, crease positions and other fit-related details.
Reference Information
Drawings, physical samples, dimensional data or marked photographs can be provided for configuration confirmation before production.
