New Low-Temperature Resistant Blood Bag Labels for Medical Industry

2026-05-15

A new generation of low-temperature resistant Blood Bag Labels has been launched to meet the stringent requirements of blood centers, transfusion services, and clinical laboratories. Engineered for extreme cold-chain conditions, these labels solve common problems such as edge lifting, cracking, and barcode unreadability after freezing or thawing.

Withstands -80°C to 110°C, No Delamination After Freeze-Thaw

The label uses medical-grade PP synthetic paper and a special acrylic adhesive that remains effective from -80°C (ultra-low freezer) up to 110°C. Validated per blood bank protocols:

■ -18°C for 24 hours – no lifting, no adhesive failure, no embrittlement, no edge curling.

■ -30°C for 24h → 37°C water bath for 1h – no delamination, no shape change, strong adhesion remains.

Reliable Under High-Speed Centrifugation & Wet Surfaces

Blood component processing often causes label failure during centrifugation or on condensing surfaces. These labels have passed:

■ 5,000G for 10 minutes (at 4°C and 37°C) – no wrinkling, no detachment, no sticking between bags; barcode remains scannable.

■ Wet-surface application – directly adheres to frozen plasma bags with condensation or uneven surfaces without slipping.

■ Abrasion test – simulated bag-to-bag and finger rubbing does not remove or blur printed content.

Medical Safety & Barcode Compliance

The labels fully comply with biocompatibility requirements:

Non-cytotoxic, non-hemolytic, low migration. Remain scannable after freezing and centrifugation. Mandatory information area (donation code, product code, blood type with Rh, collection/expiry dates, facility code, volume, storage conditions) is presented in high-contrast black-on-white. Rh(D) negative can be specially marked.

Print & Disinfectant Resistance

Designed for thermal transfer + resin ribbon – low-temperature resistant, no fading or bleeding. The surface coating resists alcohol / isopropanol wiping for disinfection. The liner has low shrinkage to further prevent edge lifting.

These new labels are now available for sample testing to blood stations, hospital blood banks, and medical supply distributors. For technical datasheets or trial requests, please contact Juncheng.
