Refillable heavy duty polypropylene 0.2mm thick sleeves. Each protector has an 11 hole punched margin.
Polypropylene is suitable for archival preservation and art presentation.
Unlike PVC sleeves, which contain volatile plasticizers (softener) and emit damaging hydrochloric acid as it deteriorates.
Polypropylene is considered archival safe as it is chemically stable and as close to PH neutral as technically possible with plastic and does not contain any plasticizers.
