Industrial bags are made of durable, heavyweight polyethylene material to withstand a variety of environments. Clear, heavy-gauge bags let you store everything from computer reports to paper clips. Airtight and waterproof when they are secured with the poly zip seal, ensuring that vital information stays clean, visible and easily accessible. Bags are punched at the top for easy hanging purposes. The poly bags can store manuals and work orders, while also enclosing smaller sized items inside the shop ticket holder.
