Further information on Correx® sheet material

Correx® is a specific type of corrugated plastic sheet, which is now in widespread use across much of Europe.

It is an extruded, twin wall, fluted polypropylene sheet material, which can also have numerous additives included during the manufacturing process to provide specific properties including flame retardant and UV resistant.

Colours can also be added to the base polymer to achieve a wide variety of colours.

It is widely used in a large number of industries as it is more durable and long lasting that corrugated cardboard, lighter than wood and is resistant to water and most chemicals.

It is also usable at low temperatures, easy to die-cut and weld, and is fully recyclable. This makes it the ideal material for applications, such as reusable packaging manufacture for a wide range of market sectors.

Sourcing Correx® from GWP

As well as standard Correx® sheets, a “cloth covered” Correx® is also available.

By providing all the benefits of standard Correx®, such as strength, rigidity, a long lifespan, easy fabrication, resistance to water etc., cloth covered Correx® goes one step further by providing additional protection to any surfaces coming into contact with it.

This is particularly important for any product with a highly polished painted or delicate surface finish.

Besides being one of the leading fabricators of Correx® packaging products in the UK, an extensive stock holding of Correx® sheet also allows you to source raw material in sheet form at very competitive prices and low volumes.

Advantages of Correx® material

  • Long lasting and hard wearing
  • Rigid, yet lightweight
  • Can be easily fabricated and converted
  • Wide range of uses in the construction, automotive, materials handling and other industries
  • Wide range of colours & thicknesses available
  • Fabric laminated, cloth covered Correx® available pre-fabricated or in sheets at GWP


Performance data for Correx® material

Please see below for the specific performance / properties of Correx® material. Alternatively, you can download the product datasheet for a full list of sizes and details.


  • Softening temperature (BS2782: 102D ISO 1306) 85°C
  • Crystalline melting point 160 – 175°C
  • Flash ignition temperature c a 350°C
  • Self ignition temperature ca 380°C
  • Calorific value 11000
  • Specific heat 0.46 cal/gm°C
  • Limiting oxygen index (ASTM D 2863) 0.174 – 0.180
  • Burn rate (FMVSS 302) 5.3 – 8.2 cm/min


Correx® Sheet is made from ethylene propylene copolymer which is resistant to impact. At normal operating temperatures ranging from approximately 0’C to 85’C a high level of impact resistance is expected.

Above 85’C the material starts to soften, increasing the impact performance but at the same time losing structural strength. The material will continue to soften until approximately 140’C where the polymer begins to melt.

At temperatures below 0’C Correx® sheet becomes more rigid but at the same time becomes more brittle.

At -18’C the impact strength is reduced by approximately 10%. No measurements have been taken for impact performance below -18’C in Correx® sheet but other industries routinely use polypropylene copolymer at temperatures down to -30’C (e.g. for ice cream tubs).

Down to temperatures around -30’C one can expect the structure of Correx® to remain intact so long as the product is not subjected to unreasonable treatment. One would expect Correx® boxes to perform well in an environment such as on shelves, single stacked.


Common questions regarding Correx®

Thinking of using Correx® sheet, but have some questions first? The below section should help.

However, please contact a friendly adviser on 01793 754 457 or email if you haven’t found the info you need.

What is Correx®?

Correx® is an extruded, twin wall board manufactured from polypropylene plastic / co-polymer granules. Commonly referred to as fluted or corrugated plastic (and sometimes even plastic cardboard) it is a surprisingly durable yet lightweight sheet material.

What is Correx® used for?

Correx® is suitable for a wide range of applications (both internal and external) thanks to their twin walled construction and polypropylene material. This includes use for signage, protection of surfaces during construction etc, permanent formwork and of course returnable transit packaging.

Is Correx® waterproof?

Correx® is one hundred percent waterproof. This it makes suitable for both internal and external applications. Other useful properties include high levels of strength relative to its’ weight, resistance to most chemicals / oils and being easy to clean

What is the difference between Correx®, Coroplast, Corfulte, Twinplast etc.?

In essence, Correx®, Coroplast, Corflute, Corex and Twinplast are all different names / brand terms for the same corrugated plastic material. Whilst there are some minor performance variations between these, they are all largely the same product.

Is Correx® fire retardant?

Standard Correx® is not flame retardant, due to its polypropylene construction (a combustible thermoplastic material). However, with the use of additives during the manufacturing process it is possible to produce flame retardant grades.

Can Correx® be recycled?

Correx® can typically be recycled at the end of its usable life, but it may be the case that this will need to be done at a specific type of recycling centre. The general rule is if the recycling plant accepts plastic straws, then it will also be able to process Correx® material too.

Can you print on to Correx® plastic?

Correx®, and most forms of corrugated plastic, can be readily printed on to. The nature of the surfaces means that standard printing equipment (and most inks) can be used to create crisp, impactful graphics and detailed text.

Source Correx material from UK experts

GWP Correx® are predominantly packaging manufacturers, designing and manufacturing handling products such as totes and dividers, storage products such as picking bins, and even printed packaging boxes for consumer markets.

In order to ensure that businesses that use these products can benefit from the shortest possible lead times, GWP keep an extensive stock holding of Correx® material in stock at our manufacturing facility.

As a result, it means you are able to source material straight from this stock holding. This actually solves a number of issues that you may experience with other material suppliers.

MOQs? No, you can order the exact amount you need, in high or low volumes. Long lead times? No, as it is in stock, you can normally get it within 48 hours. Range of colours / sizes? Whilst we do maintain a number of different thicknesses and colours, if we do not have stock of your specific requirement, it can usually be sourced for you quickly and cost effectively.

Couple this with custom sizes (as our manufacturing capability allows us to cut sheets to whatever size you need) plus offering you a wide range of pre-fabricated products (saving you time / effort), and it makes sense to source your Correx® material from GWP.
