P-touch TZe Labels Tested to the Extreme: Extensive testing has been performed to ensure that P-touch TZe labels are incredibly durable under all kinds of conditions. They hold up extraordinarily well - and stay crisp, legible and affixed - even when subjected to abrasion, extreme temperature, industrial chemicals and sunlight. Brother's patented tape technology ensures that Brother P-touch laminated labels can withstand even heavy abrasion. Whether you want to use our labels in freezing conditions or extremely warm environments, Brother P-touch laminated labels have been designed to last. We know this because we have tested them to the extreme. In fact, results show that our laminated labels can withstand temperatures from -80°C to 150°C. Wherever you use P-touch laminated labels, they will stay as clear and legible as the day they were applied. Testing TZe labels 'to the extreme' has found them to be waterproof and resistant to chemical spill
