Large-scale thick-sheet thermoforming is economically advantageous. In the packaging manufacturing industry, unless corrugated cardboard is used as the packaging material, thick-sheet blister processing technology is unmatched by other processing methods. The main advantage of thick-sheet blister processing is its economic efficiency. For products such as composite sheets, foamed sheets, and printed sheets, large-scale thick-sheet thermoforming uses mold changes instead of changing the thermoforming machinery for thick sheets. Thin-walled products can be processed using thick sheets with high melt viscosity, but injection molding products with the same wall thickness requires particles with low melt viscosity. For small quantities of molded products, favorable mold costs are another advantage of thick-sheet blister processing. However, for large quantities of molded products, the products can achieve very thin wall thicknesses, and the high production ratio of large-scale thick-sheet thermoforming is very advantageous.
