Volm offers a variety of different closures, including threads and glues which are used to close all types of produce bags & boxes. Thread is more commonly used for sewing shut baler bags and other large produce bags while glue can be used for baler bags, cartons and containers. Both prove to be a very reliable closure companion for large, heavy bags. Our glue is available in block or chip form for a hot-melt, quick setting seal. Glue blocks or chips are easy to use in a variety of different ways to secure your packaging.
