Clear, archival-quality negative sleeves made of polyethylene are significantly more durable and tear-resistant than acetate sleeves—which is why polyethylene storage sleeves are ideal for making contact prints and for long-term archiving.
These high-quality sleeves are a safe alternative to the widely used but non-archival glassine and acetate sleeves.
