What are the adhesive label materials suitable for outdoor use? PVC and PET are the top choices for manufacturers.
Common adhesive label materials for outdoor use include PVC and PET. Whenever customers need adhesive label printing, you must provide and recommend suitable materials for the application.

Especially for labels located outdoors, labels that are continuously exposed to direct sunlight can be a challenge for label applications, as UV rays can cause labels to crack, peel, and fade. The first step in determining the label material to be used is to determine the lifespan of the adhesive label. If the usage time is relatively short, you can use lower-cost self-adhesive materials, such as paper. For anything lasting more than a few months, we recommend using durable and weather-resistant materials, such as PVC and PET, because they can withstand freezing to high temperatures (-20 to 200 degrees) as well as other factors, such as sunlight, chemicals, and wear.

1.  PVC Adhesive Label Material
PVC adhesive labels are a type of high - molecular - weight material that is non - flammable, has high strength, is resistant to climate changes, and has good geometric stability. PVC adhesive labels have strong resistance to oxidizing agents, reducing agents, and strong acids. They are flexible, have good shrinkage and opacity, are easy to process into labels, have strong chemical resistance, and are durable, making them suitable for long - term outdoor use. They are widely used in the production of trademarks, labels, clothing, curtains, holographic anti - counterfeiting materials, and other special materials.

2.  PET Adhesive Label Material
PET is actually a high - molecular - weight material, which is the English abbreviation for polyester film. PET adhesive labels are waterproof, oil - resistant, and not easy to tear. They are suitable for outdoor labels and can resist the corrosion of acids, alkalis, and other chemical substances in harsh environments. They are widely used in labels for high - performance products, such as toiletries, cosmetics, jewelry, and various electrical products. They have good weather - resistance, scratch - resistance, heat - resistance, and biodegradability. Therefore, they have become the first choice for many manufacturers.
