There was once a time that paper shredder were just used to dispose of documents that were considered to be important by the user but now a majority of people and companies use paper shredders because there are so many laws into place that will can completely ruin a person and company if they do not shred their important documents which make paper shredders very important.
The first thing that you need to know is that there are two main types which are strip cut or cross cut shredders. Strip cut shredders are the most common ones that you see everywhere and they cut the paper into spaghetti like strips but the problem with them is that the strips can actually be tapped back together, as seen in so many movies which means that they should not be used to dispose of any important documents but they can be used for junk or unimportant papers. When it comes to purchasing them, you can find them at a lot of retail stores and they are not too expensive.
The cross cut shredders are the shredders that you need to dispose of important documents as they shred papers into so many tiny little pieces that they cannot be taped back together which would keep whatever data you have on those papers, completely safe.
The capacity of the shredder refers to the number of papers the machine can shred at a single time and this is a very important feature which is why most companies look for a jam proof commercial paper shredder. The most common office shredders can shred up to 20 or 30 papers in one time but if you want more then go for a heavy duty one which can shred 40 papers.
