This cover tape has at least a base layer and a heat seal layer, wherein the heat seal layer contains a polystyrene-based resin (A) and an ethylene-(meth)acrylic acid-based copolymer (B), and contents of the component (A) and the component (B) are more than 80 parts by mass and 95 parts by mass or less and 5 parts by mass or more and less than 20 parts by mass with respect to a total of 100 parts by mass of the component (A) and the component (B).

The present application relates generally to a process of manufacturing an optimized packing material comprising chia seed mucilage (CSM), glycerol, and sorbitol, wherein said packaging materials have a good tensile strength (2.005 N/mm.sup.2), lower water vapor permeability (1.73×10.sup.−9 g×s×Pa/m), a good flexibility (e.g. high elongation at break, 31.729%). The optimum conditions of polyol concentration were 1.3 g of glycerol and 2.0 g of sorbitol per g of CSM. Based on these results, chia seed mucilage can successfully be used to develop biofilms with potential to be used in drug delivery and edible food coating applications. Both the process and the products are within the scope of this application.
