Unlined chipboard and Unlined greyboards can be supplied by Preston Board and Packaging in calipers ranging from 300micron (.3mm) up to 5000mic (5mm) thick.
Laminated Unlined Chipboard
When a material is required to be thicker than the maximum single ply caliper of 1250mic (1.25mm) two or more plies have to be laminated together.
This is done at Preston Board using a reel to sheet laminator. Poly vinyl acetate (PVA) glue is applied in between each ply to bond them together. This operation adds strength to the finished board.
On the reel to sheet laminating machine, board from 600micron (.6mm) up to 5000micron (5mm) in thickness can be produced up to a maximum size of 2000 x 3200mm.
On the laminator at Preston board we can combine a variety of paper and board substrates to provide different finishes and strengths to the end product.
