Waterproof Stickers for Varying Moisture and Outdoor Use
Waterproof stickers are always a good choice when moisture conditions vary at the application site. This is common in outdoor environments, but even in indoor spaces like cold storage, refrigerators, or freezers, moisture conditions can present challenges. It is recommended to choose a film quality that reacts to temperature changes in the same way as the surface it is applied to. Otherwise, prolonged temperature expansion or contraction may eventually wear out the adhesive, causing the sticker to detach at the edges. The same risk occurs if moisture penetrates the sticker film itself.
Where Should Waterproof Stickers Be Used?
Waterproof stickers can be used in various areas, such as boats, vehicles, outdoor environments, and industrial settings, where the sticker must withstand varying weather and moisture conditions. For example, stickers applied to the side of a boat or warning and informational labels used in freezers require particularly waterproof materials, as they are constantly exposed to water and moisture. Outdoor signage and advertising stickers also benefit from waterproofing, as they are subject to the elements. Waterproof stickers ensure long-lasting and reliable performance in all these demanding conditions.
What Types of Waterproof Stickers Can You Order from Tarra-Tac?
PP Sticker (Polypropylene):
The operating temperature for polypropylene ranges between -30°C and +90°C, depending on the grade. PP can be melted and reused or burned as an energy source.
PE Sticker (Polyethylene):
Polyethylene is the most affordable and widely used plastic in the world. It has good chemical resistance, except to strong acids. Most plastic containers are made of PE. When using polyethylene as an adhesive surface, a special adhesive is required because the surface of PE plastic is slippery. The operating temperature ranges between -30°C and +80°C, depending on the grade. We also produce BS5609 certified stickers from this material for maritime use.
PVC Sticker (Polyvinyl Chloride):
The main advantage of PVC stickers is their superior UV resistance. Vinyl stickers are used when a long lifespan is required, and they are exposed to the elements. When the adhesive surface is irregular, it is advisable to use vinyl stickers as they are the most flexible among plastics. The operating temperature range for PVC stickers is between -40°C and +110°C, depending on the grade.
PES Sticker (Polyester):
We produce polyester stickers when a tough plastic is required with high heat resistance. The operating temperature ranges between -40°C and +225°C, depending on the grade. The advantage of polyester stickers is their minimal thermal expansion or contraction. We also offer silver polyester stickers (3M 7983), whose matte silver surface is ideal for machine labeling solutions. Additionally, the surface of the silver polyester has a coating that allows for marking with a pen.
PU Sticker (Polyurethane):
A highly flexible plastic material suitable for applications with an operating temperature range of -40°C to +80°C.
PVC-Free Stickers:
For certain applications where fire regulations prohibit the use of vinyl, we manufacture stickers using PVC-free films.
