Below is a list of Resealable Plastic Bags manufacturers from Azusa, California. Resealable plastic bags include all baggies designed with a closure mechanism that can open and be re-fastened for continued product containment. Many such bags are meant for reuse, making resealing essential. The possibility of multiple uses also requires manufacturers to produce bags of more durable materials than single use poly bags. Polypropylene, polyethylene and vinyl are popular options and are available in different grades or gauges with common thicknesses ranging between 2 and 6Mil.
