Packaging materials

We produce packaging using a range of materials: paper, folding box-board and corrugated packaging.

Our expert team will suggest a suitable material for your project.

Material selection.

As a packaging specialist we source board from multiple mills and merchants; in stock sizes and in special making sizes based on your project. 

  • Folding Boxboard - Describes packaging board that is greater than 300 micron in thickness.
  • Corrugated Board - Describes board that is made up of 3 layers with a middle wavy fluted layer, giving extra cushioning, rigidity and strength.


Folding boxboard.

Also known as Paperboard or Carton-board, available in a range of thicknesses and grades as:

  • White board - Available with a coated or uncoated surface.
  • Coloured board - Colourful uncoated boards for a unique look & feel.
  • Mirror boards - Premium shiny metallic look to packaging.


Sustainable: All board is easily recyclable and sourced sustainably with FSC or PEFC accreditations.


Corrugated boxboard.

Micro-flute boards can be printed directly and boards E,F & B flute use a litho-lamination process to print on corrugated boards.

This gives the benefits of a lightweight material with extra cushioning, rigidity and strength. Plus the high print quality of a litho print process.

Sustainable: All board is easily recyclable and sourced sustainably with FSC or PEFC accreditations.


Speciality boards.

 We can source specialist board, as required for all kinds of applications.

  • Food Grade - Board is manufactured and stored in a high hygiene environment to ensure its suitability for direct contact with food.
  • Freezer Grade - Specially treated for moisture resistance required for use in freezers.
  • Grease Resistant - Specially treated for grease resistance.


Recycled vs. recyclable.

All board is easily recyclable and biodegradable.

Folding boxboards are almost exclusively available as virgin fibre board.

Only very limited options are available as recycled packaging boards; the strength and rigidity needed for packaging means long virgin fibres are required.

To demonstrate your packaging board comes from sustainable sources. We can add the appropriate FSC or PEFC logo to your packaging design.


The most common grades of board we use:

  • 1 sided board GC1 - white back folding boxboard Offers a great printed surface 1 side and a white reverse that can also be printed with a more uncoated texture.
  • 1 sided board GC2 - cream back folding boxboard   Offers a great printed surface 1 side and a cream reverse with a more uncoated texture
  • 2 sided board SBS - double sided board  Offers a great printed surface 1 side and a cream reverse with a more uncoated texture.
  • Food grade board - many widely available boards are suitable for direct contact with food.
  • Freezer grade board - board that is suitable for use in the freezer
    Grease resistant board - board that is grease resistant for food packaging.
  • Kraft board - brown board that is suitable for printing.  As standard this has one smooth side and one uncoated side.
  • Mirror board - a board that has been laminated with a silver, gold or other metallic surface suitable for printing.



Corrugated boards:


  • Micro flute board - N flute is a micro flute board allows for extra rigidity and due to its thickness of less than 1mm it can still be litho printed to directly
  • E-flute litho laminated board - A litho printed sheet is laminated onto with an E-flute to give a thicker (1.5mm - 2mm) and more rigid board to cut and crease.
  • B-flute litho laminated board - A litho printed sheet is laminated onto with an B-flute to give a thicker (2.5mm - 3.5mm) and more rigid board to cut and crease.


Material FAQ's

  • What Packaging Boards do you use?

    The material we use for our packaging is chosen to ensure it is appropriate for the intended application. We offer the following materials where appropriate:

    1. Single side coated boards - 1 side of this folding box board is clay coated giving the ideal smooth surface for printing. The other side is un-coated and the fibers of the board can be seen which is normally left for the inside of the box. But this can also be printed on and will give an un-coated look and feel to the printed result.

    2. Double side coated boards - both sides of the board are clay coated. Making this perfect for double sided printing.

    3. Micro Corrugate boards - The mailer boxes on our site use an N-flute micro-flute. Which gives both the very smooth coated surface of a standard packaging board on addition to the strength and rigidity required for postal mailer boxes.

    4. Standard Corrugated boards - Thicker than micro corrugated boards these offer greater strength and rigidity to these materials. You will be familiar with the double walled variety used as brown Kraft packaging boxes. But we can also laminated a high quality printed sheet to give a high quality printed finish.

    5. Kraft Board - Brown Kraft board is an un-coated board so feels slightly fibrous. This is often best printed with UV cured inks to give a more vivid print finish. This can be enhanced by first printing in white.

    6. Mirror Board - Mirror board is available in different metallic finishes the most common being Silver. This can be printed on with a mixture of specialist inks to give unique metallic finishes.

  • What is difference between standard board and corrugated board?

    A corrugated board. Is constructed of three layers generally. The top and bottoms layers sandwich a fluted core which adds strength and rigidity while remaining lightweight. Whilst a standard packaging board will also be constructed of at least 3 layers but will not have any fluting.

  • What weight board do you use in gsm?

    Packaging board is measured by the thickness rather that the weight as this is more relevant for packaging applications. So unlike grading material by weight as used for commercial print in brochures and leaflets etc. Instead we grade packaging materials by their thickness, this is measured in microns. 1000 microns is equal to 1mm. For most applications a thickness of around 500 microns (0.5mm) would be used.

  • Are the materials you use environmentally friendly?

    Yes the material we use is sourced from sustainable sources we use material accredited by the PEFC or FSC for our standard boxes.

    Recycled packaging material suitable for high-end print finishes is not widely available. But if this is something that is important for your project get in touch.

  • Can I supply my own material for you to print onto?

    No this is not possible. We only print onto material sourced by us.

    No, sorry we are only able to use material we have sourced ourselves

    The material we use is the result of many years of experience and we are confident it will produce the high quality results we expect

  • Do you provide food grade packaging material?

    Yes we can provide food and toy grade packaging material. As well as using low migration inks suitable for producing food grade packaging.

    If your product is to be stored in the fridge or freezer let us know and we can ensure a suitable freezer grade board is used.
