  • High-quality blended polyethylene
  • Puncture proof tabs by extending the tape on the tab past the aluminum wire ends eliminating the sharp points which could puncture the bags or gloves
  • Leakproof closure (whirling or tightly folding the tab over 3 times) prevents impurities from entering the bag and contaminating the sample
