綠色食品標(biāo)準(zhǔn)對(duì)紙類包裝有何要求？紙類是常見的包裝材料。造紙的原料主要是各種紙漿、如木漿、棉漿和草漿等，加入化學(xué)輔助原料，如硫酸鋁、純堿、亞硫酸鈉等。純凈的紙是無(wú)毒的，但食品包裝用紙安全性可能存在以下影響因素：紙的原料有污染物，影響接觸的食品；經(jīng)熒光增白劑處理的包裝紙中有熒光化學(xué)物質(zhì)；包裝紙涂蠟層中具有多環(huán)芳烴；紙面印刷油墨和顏料中含有各種有機(jī)物；紙面長(zhǎng)霉，污染接觸食品等。

綠色食品對(duì)紙類包裝基本要求是：包裝可重復(fù)使用、回收利用或可降解；紙表面不允許涂蠟、上油；不允許涂塑料等防潮材料；紙箱連接應(yīng)采取粘合方式，不允許扁絲釘釘合；紙箱上所做標(biāo)記必須是水溶性油墨，不允許用油溶性油墨，以保證食品安全并減少環(huán)境負(fù)擔(dān)。
