Plastic Substrates

Plastics are typically synthetic materials derived from petrochemicals, though natural polymers like rubber and cellulose (used in paper) also exist. Plastic substrates provide unique benefits over paper, such as durability, weather resistance, flexibility, and optical clarity—making them ideal for both indoor and outdoor print applications.

Here's a closer look at the most widely used plastics in print, their applications: 

• Acrylic Substrates (PMMA)

  • Trade Names: Perspex, Plexiglas, Lucite, Acrylite

  • Applications: Clear signage, displays, glazing alternatives

  Acrylic is a transparent, rigid plastic often used as a lightweight alternative to glass. While cheaper than polycarbonate, it’s not as impact-resistant or scratch-proof. It doesn’t contain BPA, making it a safer option in some contexts.

Mylar Substrates (BoPET)

This metallized PET film is known for its reflective, decorative qualities and strength. It’s commonly used in special effect printing.

PET Substrates 

• Also Known As: Polyester, Mylar (when metallized)

• Applications: Backlit displays, banners, packaging

PET is popular for its clarity and strength. PET-G (glycol-modified PET) is used in printable sheets and thermoformed applications thanks to its lower melting point.

Polycarbonate Substrates

Polycarbonate is a tough, clear plastic often used in high-impact signage and industrial displays. It contains BPA and is no longer approved for use in baby bottles.

Polyester Substrates

• Applications: Printable textiles, dye sublimation media, soft signage

Polyester is a broad category that includes PET and polycarbonate. It’s widely used in textile applications, especially for dye-sub printing.

Polyethylene Substrates (PE)

• Variants: HDPE, MDPE

• Applications: Films, packaging, banners

Polyethylene is everywhere—from milk bottles to shrink wrap. It’s flexible, durable, and widely recycled.

Polypropylene Substrates (PP)

• Applications: Labels, posters, POS, overlaminates

PP is water-repellent and solvent-resistant, making it ideal for industrial and promotional uses. However, it's tricky to print without specialized inks.

Polystyrene Substrates (PS)

Used mostly in packaging, PS can be injection-molded or foamed. It’s found in everyday items from takeaway boxes to display materials.

Vinyl Substrates (PVC)

The most widely used plastic in print. Vinyl is incredibly versatile, making it the go-to for outdoor graphics, labels, and decor.

Plastic substrates have revolutionized the digital printing industry. These materials offer creative and practical solutions for virtually every print application. Whether you're focused on durability, aesthetics, or recyclability, choosing the right substrate can elevate the quality and longevity of your printed work.
