Abstract
Most of current packaging tape are made of non-degradable BOPP film, subsequently rendering carton recycled lose commercial value and causing a great hazard on the living environment. PVA film is known as a type of environmentally friendly material because of its excellent characteristics, e.g. water solubility and degradability. Since PVA film has strong polarity, it is necessary to coat surfactants to reduce the surface tension. In the paper, Span20, Span60, Span80 and Tween60 were coated on the other side of PVA hot-melt adhesive tape by hand. The surface tension was measured under different placement time. It measured the 180° peel strength of PVA hot-melt adhesive tape coated with surfactants in comparison to PVA hot-melt adhesive tape without surfactants and BOPP tape so that appropriate surfactants were chosen. The results show that the surfactants can reduce surface tension of the other side of PVA hot-melt adhesive tape. However, only the mass ratio of Span60 and C2H6O is between 1:5 and 1:10, the 180° peel strength of PVA hot-melt adhesive tape is the best. PVA hot-melt adhesive tape with other surfactants is stuck together when the tape is crimped or its peel strength is too small.
