Less extensible film — stiff overwrap from resin with a density of 0.935 g/cm3, or a high density, paper-like film — does not have the ability to stretch. The broad "smile" wrinkles appear if no attempt is made to increase the edge velocity. However, if the edge velocity is too great, edge wrinkles occur.

PP PE Stone Paper Extrusion Line Production cost advantage. Each ton of stone paper contains raw materials, electricity and manpower, and the cost is about 4,000 yuan/ton, which is at least 1/3 lower than the cost of traditional wood pulp paper. Each production line only invests 10 million-15 million or so, the input-output ratio is high, and ...
