Transparent PET Cryogenic and Freezer Labels for Liquid Nitrogen Cryo Vial Laboratory Identification

Overview

B-377G is a transparent PET cryogenic label specifically engineered for biological and biomedical laboratories requiring reliable identification under extreme low-temperature conditions.
Designed for cryo vials and laboratory tubes, this label maintains secure adhesion during long-term liquid nitrogen storage at -196°C, ensuring labels remain legible and firmly attached without lifting or edge curl.

With excellent clarity and chemical resistance, B-377G supports laboratory sample identification, tracking, and inventory management in cryogenic freezers, ultra-low temperature storage systems, and biobank environments. The transparent PET construction allows underlying markings or vial graduations to remain visible while providing durable, permanent labeling performance.

Feature

• Ultra-Low Temperature Resistance (-196°C)
  Engineered as a true cryogenic and freezer label, B-377G withstands prolonged exposure to liquid nitrogen without cracking, shrinking, or label opening.

• Permanent Adhesion for Cryo Vials
  Specially formulated adhesive ensures strong bonding to plastic cryo vials and laboratory tubes, even during repeated freeze–thaw cycles.

• Transparent PET Film
  Clear PET material enables unobstructed visibility of vial contents, barcodes, and graduations, ideal for laboratory sample identification.

• Edge-Lift and Peel Resistance
  Maintains flat adhesion in cryogenic freezers and ultra-low temperature environments, supporting long-term sample storage and traceability.

• Laboratory-Compatible Printing
  Suitable for thermal transfer printing, delivering sharp text and barcodes for cryo vial labeling and sample tracking.

Application

• Cryo Vial Identification in biological and biomedical laboratories

• Liquid Nitrogen Storage Labels for cryogenic freezers and Dewar tanks

• Laboratory Sample Tracking in research institutes and clinical labs

• Biobank Sample Management and long-term archival storage

• Pharmaceutical and Biotechnology Laboratories requiring reliable cryogenic labeling

• Ultra-Low Temperature Freezer Labels for -80°C to -196°C environments
