2、透氧量表示塑料薄膜材料在一定的條件下對氧氣的透過量，比如在相對濕度為90%、溫度為23℃的情況下，24h內(nèi)厚度為25μm的塑料薄膜每平方米所透過的氧氣的體積。各種薄膜材料的透氧量也有所不同。 3、幾何尺寸穩(wěn)定性塑料薄膜必須具有一定的幾何尺寸穩(wěn)定性，否則，其伸縮率過大，在印刷和復(fù)合過程中受到機(jī)械力或者受熱量的作用容易產(chǎn)生伸縮變形，不*會影響套印精度，還會出現(xiàn)皺折、卷曲等問題，嚴(yán)重影響產(chǎn)品質(zhì)量和生產(chǎn)效率。塑料薄膜功能齊全，種類繁多，有長壽型的，消霧流滴型的。河南復(fù)合薄膜價格</p><p
