在杂志纸行业从事25年或更长时间的人可能仍记得,杂志最初采用定量60g/m2和65g/m2的SC纸作为封面用纸。当时市场上只有这种等级的SC纸,后来又改用低定量涂布纸(LWC)以及几种重涂的涂布纸作为封面纸。
People who have been in the magazine paper industry for 25 years or longer may still recall that the magazine initially adopted SC paper of 60 g / m2 and 65 g / m2 as the cover sheet. Only SC grades of paper were available on the market at that time, and later switched to LWC and several overcoated coated papers.
