Choosing The Right Zip Lock Bag

With sizes ranging from extra small to extra large, you are sure to find the appropriate top-seal bags for packing and storing your daily items. These top-seal bags are made of polyethylene, and meet the FDA requirements, which are safe for foods. They can keep foods and items fresh, clean, and free from oxidation.

Except the dimensions of the bag, the mil thickness is another important factor in choosing the right zipper lock bag. Please note that the thickness is the unilateral thickness of bag’s bottom. Mil is a measurement unit used to measure the thickness of film.
