| Acid FreeAcid free paper has a pH of 7.0 meaning that it is a neutral.  Any type  of paper can be acid free it simply needs to be treated properly during  the manufacturing process so there is no acid in the pulp.
 “During  production, acid-free paper may be treated with a mild base to  neutralize the natural acids occuring in wood pulp, and it may also be  buffered to prevent the formation of additional acids” www.wikipedia.com

 Lignin FreeMany non-archival papers have high lignin content (such as newspapers) causing the paper to deteriorate and become yellow over time.  Lignin causes acid to re-form in the paper over time.  Any type of paper can be lignin free it simply needs to be treated properly in the manufacturing process so the lignin is removed.
          "Lignin or lignen is a complex chemical compound most commonly derived from wood and an integral part of the cell walls of plants" www.wikipedia.com

 PVCPVC is used in plastics such as the clear protector in photo albums.   PVC releases chloride over time which speeds the deterioration of  photographs.  When creating archival scrapbooks everything must be PVC  free.
 “Polyvinyl chloride is used in a  variety of applications. As a hard plastic, it is used as vinyl siding,  magnetic stripe cards, window profiles, gramophone records (which is  the source of the term vinyl records), pipe, plumbing, and conduit  fixtures. The material is often used in Plastic Pressure Pipe Systems  for pipelines in the water and sewer industries because of its  inexpensive nature and flexibility.  It can be made softer and more  flexible by the addition of plasticizers. In this form, it is used in  clothing and upholstery.  It is also commonly used in figurines”. www.wikipedia.com
