Sidewinder 100 - 1 X 100 PROCESSING BAGS (100 ct). Many people find it convenient to use Sidewinder processing bags in their waste management programs. You must still use a bucket if you choose to use Sidewinder processing bags. Just place the Sidewinder processing bag in a clean open top metal bucket and fold down the sides like lining a waste can. For best results when using Sidewinder processing bags, start with a clean open top metal bucket; bags will stick to dirty buckets containing paint or coatings residue.
