Evaluation and comparision of mechanical and barrier properties of stone paper and gloss paper
Paper is one of the main packaging materials that can protect the product from damage without sacrificing its quality while being flexible, degradable, recyclable, and printable. Recently, a new generation of materials with the name of the stone paper has entered the market that one of its uses is in packaging. In this paper, the mechanical, barrier and optical properties of this type of paper are evaluated and compared with gloss paper, which is a high-quality type of cellulose fiber paper. The results showed that stone paper is almost impermeable in barrier properties such as water vapor transmission rate, oil passage and water absorption. Comparison of optical properties indicated that the stone paper is less transparent than gloss paper and paperboard, but it is more transparent. The tear strength and elongation of stone paper is more than glossy paper and paperboard. However, the tensile strength and burst strength of gloss paper and paperboard is more than stone paper.
