Cellulose is the most abundant polymer found in nature and in some forms is used as heat-sealable paper for medical packaging applications where it acts as a filter to particulates and microorganisms, while at the same time permitting free passage of gas and water vapor during sterilization. This paper must also be heat-sealable over plastic trays that contain medical instrumentation. The bond of the paper to the plastic must be sufficiently strong, but at the same time capable of being peeled

The additive that was found to be suitable as an adhesion promoter was alkylpolyglycoside (APG), a nonionic surfactant, in combination with cellulose acetate fibers (CA). [1] For heat-sealable paper, a mechanism for improved adhesion for APG and CA containing paper was proposed in which APG anchors itself in the cellulosic matrix and acts as a plasticizer for CA. [1] In order to test this hypothesis, Atomic Force Microscopy (AFM) was employed, as it is a non-destructive analytical tool capable of probing three-dimensional surface structures and properties at the nanoscale.
