PP Appliance Packaging Liners

PP Appliance Packaging Liners are corrugated polypropylene sheets used inside appliance packaging for surface separation, bottom protection, side protection and component organization. They can be supplied as flat sheets or processed parts according to the packaging layout. Reference thicknesses range from 2 to 12 mm, with sheet widths from 50 to 2400 mm. Finished dimensions, shape, openings and crease positions can be specified from drawings, samples or dimensional data.

Surface Separation
The liner forms a defined layer between appliance surfaces and surrounding packaging materials. It helps keep finished panels separated from carton walls and adjacent packaging parts during handling and transportation.
Board Rigidity
The hollow corrugated structure provides a rigid sheet profile at a controlled material weight. Thickness can be selected according to liner dimensions, folding requirements and its position within the packaging.
Moisture Resistance
Polypropylene is suitable for packaging environments where humidity or moisture exposure needs to be considered. The sheet does not rely on paper fibres for its structural form.
Reusable Use
PP corrugated liners can be removed, cleaned and reused when incorporated into a returnable packaging system. This suits packaging layouts that use repeated handling and consistent liner dimensions.

Bottom Liners
Placed below an appliance to create separation between the product base and the carton, pallet or other packaging components.
Side Liners
Positioned along appliance panels or side walls to separate finished surfaces from the outer packaging structure.
Surface Separators
Used between appliance surfaces or packaging layers where a defined separation layer is required.
Component Separation
Cut or folded liners can divide accessories, parts and internal components within the same packaging unit.

Corrugated PP Board
The liner is produced from hollow corrugated polypropylene sheet with internal ribs between the outer surfaces. Board thickness is selected according to part dimensions and the required packaging structure.
Flat Liners
Rectangular sheets are suitable for bottom pads, side panels and layer separation where no additional folding is required.
Folded Parts
Crease lines allow the sheet to fold around appliance edges, corners or defined packaging sections.
Die-Cut Parts
Custom outlines, slots and openings can be processed when the liner needs to match an appliance profile or internal packaging arrangement.

PP Sheet
Corrugated polypropylene provides the base structure for the liner. Material thickness is selected together with part dimensions and the required packaging configuration.
Cutting
Straight cutting produces specified sheet lengths and widths for flat liner layouts and prepared packaging components.
Creasing
Crease lines can be added where the finished part needs controlled folding around appliance edges, corners or packaging sections.
Die-Cutting
Die-cut processing allows openings, slots and non-rectangular profiles to follow an approved drawing or physical sample.

Dimensions
Liner length and width can be matched to the available packaging space and appliance dimensions.
Thickness
Thickness can be selected within the 2–12 mm reference range according to part size, rigidity and folding requirements.
Shape
Flat, folded and irregular profiles can be produced for different positions inside the packaging.
Processing Layout
Cut-outs, slots and crease positions can follow the approved drawing. Color can also be specified for production identification or packaging organization.

Check Appliance Dimensions
Start with appliance length, width, height and the surfaces requiring separation or protection.
Define Liner Position
Identify whether the liner is required at the bottom, side, top, between layers or around internal components.
Set Board Thickness
Consider liner dimensions, folding structure and required rigidity together when selecting the board thickness.
Confirm Processing
Specify straight cutting, creasing, die-cutting, openings or combined processing before production.

Thickness Inspection
Board thickness is checked against the approved specification to maintain consistent sheet dimensions.
Dimension Inspection
Sheet length, width and finished part dimensions are checked against drawings or confirmed samples.
Processing Accuracy
Crease positions, openings and die-cut profiles are checked against the approved processing layout.
Batch Consistency
Sheet structure and thickness are monitored during production to maintain consistent material characteristics between production batches.

Appliance Information
Provide appliance length, width, height, protected surfaces and the intended liner position.
Technical Files
Drawings, CAD files, packaging layouts or physical samples can be used to confirm the liner structure and processing requirements.
Production Details
Specify thickness, finished dimensions, quantity, color and required cutting, creasing or die-cutting operations.
Final Specification
Approved dimensions, thickness and processing details become the production reference for the finished liner.
