White plastic signs are commonly made from acrylic, polycarbonate, or fluted polypropylene. Acrylic, also known as plexiglass, is lightweight, strong, and UV-stable, making it suitable for outdoor use. Polycarbonate is even stronger and more durable than acrylic, offering excellent impact resistance, while fluted polypropylene is a cost-effective option that is often used for outdoor signs such as political or real estate signs. Other materials used for white plastic signs include PVC, styrene, and polyethylene. These materials can be customized with various thicknesses, colours, and mounting options to fit specific requirements.

Polycarbonate is a strong, durable material, ideal for long retail signs
Plastic signs are a versatile, durable, and cost-effective solution for retail stores, offices, trade shows, and public spaces. They can be used to advertise sales, promotions, and products, as well as provide important information such as directions, safety warnings, and parking instructions.
Polycarbonate is a type of plastic that is well-suited for long retail signs. It is a strong and durable material, known for its impact resistance and ability to withstand extreme conditions. Polycarbonate is 200 times stronger than glass and 15 times stronger than standard acrylic sheets. This makes it an ideal choice for areas where the sign may be subjected to potential vandalism or high-traffic areas.
Polycarbonate sheets are available in a variety of sizes, thicknesses, and colors, including white. They can be purchased as standard sheets or off-a-reel, allowing sign makers to obtain one continuous piece of material up to 300 feet long. This flexibility in sizing makes polycarbonate ideal for long retail signs that require a single, uninterrupted display.
In addition to its strength and versatility, polycarbonate also offers excellent clarity. This feature, combined with its durability, makes polycarbonate suitable for both indoor and outdoor applications. Polycarbonate sheets can be used with LED lights to create brilliant backlit signs without visible hotspots, enhancing the visibility of the display.
Furthermore, polycarbonate sheets can be treated with UV stabilizers to extend their lifespan when used outdoors. This treatment helps prevent fading, yellowing, and brittleness that can occur in plastics due to prolonged exposure to sunlight. With proper care and maintenance, polycarbonate signs can last for many years, making them a cost-effective choice for retail signage.

Acrylic is lightweight, easy to machine, and offers great light transmittance
White plastic signs can be made from various materials, including Komatex, polycarbonate, styrene, and acrylic. Acrylic, in particular, stands out as a versatile and highly advantageous material for signage.
Acrylic is a transparent thermoplastic material with excellent stiffness, strength, and optical clarity. It is produced with UV inhibitors in the resin, making it UV stable and resistant to years of sun exposure. Acrylic is also highly impact-resistant, and its natural strength makes it ideal for applications requiring routing, such as channel letter production.
One of the key benefits of acrylic is its lightweight nature. Acrylic sheets are 17 times stronger than glass yet significantly lighter, making them easier to transport, handle, and install. This lightweight property, combined with its strength and durability, makes acrylic a popular choice for architectural applications, such as windows, wall partitions, lighting fixtures, and canopies.
Acrylic is also known for its exceptional light transmission properties. It transmits up to 92% of visible light, providing excellent optical clarity, transparency, and light diffusion. This makes acrylic well-suited for illuminated lighting applications, such as lightbox signage systems, and backlit displays.
In addition to its lightweight and light transmission advantages, acrylic is easy to machine, fabricate, and thermoform. It can be easily cut and routed and fabricated into various shapes, including letters, using ordinary woodworking tools. Acrylic's superior machining characteristics and ease of handling make it a versatile material for a wide range of applications beyond signage, including lighting fixtures, safety shields, and architectural glazing.
Overall, acrylic's combination of lightweight, strength, durability, and excellent light transmission make it an ideal material for white plastic signs. Its ease of machining and versatility further contribute to its popularity in the sign manufacturing industry.

Polyethylene is a cheap material, used for full-colour flat panel signs
Polyethylene is a cost-effective material for full-colour flat panel signs. It is a synthetic material that is neither difficult nor expensive to produce, making it more affordable than metal or wood. Polyethylene is also durable, cold-resistant, and non-yellowing, and it accepts inks and digital prints well.
Polyethylene signs are available in various thicknesses, with popular options being 1/16″ and 1/8″, and can be purchased in thicknesses of up to 1/2″. The most common shape is rectangular, which can be posted on a gate, fence, or in a frame. Polyethylene is also suitable for laminating digital graphics for retail and trade show displays.
Flat-panel signs are commonly used for effective branding and can be made from a variety of materials, including polyethylene. These signs are cost-effective, lightweight, and easy to install, with high-quality digital printing options. They are also versatile, allowing for customisable shapes and sizes.
Other materials used for flat-panel signs include aluminium composite, which is durable, weatherproof, and suitable for long-term indoor and outdoor use, and Correx (fluted polypropylene), which is very economical and lightweight, making it suitable for short-term indoor use or temporary signage. Foam board is another option, offering lightweight and cost-effective characteristics, with various thicknesses available for indoor use.
For high-impact signage suitable for both indoor and outdoor use, Perspex (acrylic) is a durable and weatherproof option with excellent clarity and scratch resistance. Acrylic is another popular choice for indoor and outdoor signs due to its lightweight, strength, and great light transmittance. Polycarbonate is often used for long retail signs and cabinet signs, offering exceptional strength and durability, making it ideal for areas where panels need to withstand extreme conditions.

Fluted Polypropylene is cost-effective, but doesn't easily accept ink
Fluted polypropylene is a cost-effective material for creating signs. It is a corrugated plastic sheet that is durable, UV-treated, and easy to work with. These twin-wall polypropylene sheets can be easily cut with a standard utility knife and are available in a variety of colours, including white. They are ideal for short-term yard signage, tradeshow booths, point-of-purchase displays, and special event signage.
However, one challenge with using fluted polypropylene for signage is that it does not easily accept ink. This can make the printing process more complicated and may require specialised inks or printing techniques. While fluted polypropylene is printable, the ink adhesion may not be as strong or durable as with other materials.
To address the challenge of ink adhesion on fluted polypropylene, specialised inks such as Corribond screen inks have been developed. These inks are specifically formulated for use on fluted polyolefin sheets, offering excellent adhesion and durability. With these inks, it is possible to achieve high-quality printing on fluted polypropylene, making it suitable for a range of applications such as display signs, folders, and estate agent boards.
Additionally, there are other ink and coating solutions providers, such as Polymeric, that offer customised solutions to their customers. They work closely with their clients to understand their unique challenges and develop innovative products to meet their specific needs. By collaborating with such specialists, it may be possible to optimise the printing process and enhance the ink adhesion on fluted polypropylene.
Overall, while fluted polypropylene may not easily accept ink, there are ways to overcome this challenge. With the right inks and printing techniques, it can be a cost-effective and durable option for creating signs and displays, especially for short-term applications.
