Selection of polyethylene plastic zipper seal sandwich bags with a resealable zip lock. The zipper seal sandwich bags are ideal for packing, storing, shipping, sampling and sorting. The plain zipper seal sandwich bags are available in 11 practical sizes with a 4 mil thickness.

These bags will hold up in a convection oven at temperatures of 90°C/195°F, remember that the air in the bag will expand during initial heating.

Zipper seal sandwich bags are gamma sterilized, leaving an interior surface with no toxic residue from gas exposure. Samples can be easily collected by removing the tear strip above the wire closure and pulling on the two external grip tabs to open the mouth of the bag to the desired level. Using the grip tabs ensures sterility and eliminates the risk of contamination from finger contact. Then, introduce the sample into the bag, flip or fold the bag three times, bend the wires and your sample is secure inside the airtight and moisture sealed bag.

Zipper seal sandwich bags are made of virgin polyethylene for excellent clarity and strength. They meet USDA, EPA and FDA standards and are sterile, RNase-free, DNase-free and non-pyrogenic. The PVC tab that surrounds the stainless steel wire is extended beyond the wire ends to eliminate the potential for punctures, scratched hands or ripped gloves due to exposure to uncovered wire ends.
 
Several sizes are supplied with a white printed area that eliminates tapes, labels, etc. and makes markings more long lasting, clearly visible and less prone to smearing. Although these bags can contain up to 55oz (1600mL), they fold completely flat and require very little storage space.
