Key Automation manufactures and exports polyester stickers (German: Polyester-Aufkleber) for customers in Germany. Polyester stickers are widely used to label equipment and protect surfaces.

They are made from polyester film, adhesive and ink and perform reliably in demanding conditions. These properties make them popular in the automotive industry, electronics and outdoor signage. Below you will find the types, specifications, characteristics and applications.

We supply a broad range of polyester stickers for many applications:

• Clear Polyester Stickers: Made from transparent, high-quality polyester film. They give a clean, minimal look and are used where the surface underneath should stay visible.
• White Polyester Stickers: Our white polyester stickers are used for branding and product identification and are a good option for industrial stickers that need a vibrant, opaque look. They are thicker and have strong adhesion.
• Silver Polyester Stickers: Premium stickers with a metallic sheen for products and equipment where reflection and visual impact are required. They are mostly used for electronics and machinery labelling.
• Matte Polyester Stickers: Non-glossy with a textured top layer and good adhesion. They are easy to read in bright light.

Our polyester stickers offer these characteristics for demanding applications:

• High Dimensional Stability: Polyester film shrinks very little, and together with strong adhesion the sticker keeps its shape. This is helpful in outdoor conditions.
.
• Thermal Resistance: According to our specification, the stickers withstand temperatures from -40 °C to 150 °C. They are suitable for high temperatures and for cold storage, for example on automotive engine components and refrigeration units.
.
• Moisture and Humidity Resistance: Our waterproof polyester stickers perform well even in moisture and humidity. The adhesive stays reliable in kitchens, bathrooms and industrial plants.
.
• Optical Clarity: Highly transparent polyester gives excellent clarity under any lighting. Graphics are printed with good-quality ink in many colours, which suits product labelling on transparent packaging.
.

Polyester stickers are used in many applications, such as:

• Medical and Pharmaceutical Labeling: Used on medical equipment and pharmaceutical packaging. The durable material handles chemicals and extreme temperatures.
• Consumer Electronics: Applied to smartphones, tablets and computers for brand display and product information, including barcodes, logos and text.
• Laboratory and Research Facilities: Used on sample containers and research materials, resisting chemicals, solvents and changing temperatures.
• Construction and Heavy Machinery: Safety guidelines and compliance labels on machinery and construction equipment, resistant to environmental influences.

Polyester is a popular choice for German OEMs that need stable, clean labels for devices. We help you pick the right colour, finish and adhesive.

• Colours: Transparent, white, silver and custom colours are available.
