包装化妆品的材料是什么

包装化妆品的材料通常为PP，PE、K料、AS、ABS、亚克力、PET等。

PET材料为环保材料，具有高阻隔性，质轻、不碎特性、耐化学反抗性，透明性极强，可做成珠光、有色、磁白、透明，在装啫喱水方面应用广泛。瓶口一般为标准的16#、18#、22#、24#口径，可配上泵头使用。AS、ABS：AS透明度较好于ABS，且韧性较好。

压克力材质为注塑瓶，抗化学性较差，一般不能直接装膏体，需配内胆阻隔，灌装不易太满，防止膏体进入到内胆与压克力瓶之间，以免发生龟裂，运输当中包装要求较高，因划伤后看上去特别明显，通透性高，感观上壁特厚，但价格相当贵。

adv(副词)下面各组中句子的意思不同:They love him as much as she他们和她同样爱他。They love him as much as her他们爱他，也同样爱她。约翰和鲍勃一样有礼貌。John is as polite as Bob(强调约翰有礼貌)John is as polite as Bob is(强调鲍勃有礼貌)prep(介词)as, for这两个词均可作“作为；当作；用作”解,一般情况下可以互换。但as表示资格，而for表示用途。例如：She was respected as a teacher作为一名教师，她受到尊敬。She won't do for a teacher她做教师不行。另外，在regard,think of,treat等动词之后一般用as,不用for。as, like这两个词的区别是：1在作“如”“像”解时，as可用作连词，引出方式状语从句；而在正式英语中like不能这样用，只能用作介词。例如：请尽量按我这样写。Please try to write as I doPlease try to write like me作为学生，应试时须严格按照上述规定作答，但实际上在非正式的英语里，like用作连词还是很常见的。例如：I can't sing like I used to我不能像以前那样唱歌了。2as和like都可用作介词，但意义不同。as用于人时强调其身份、职业、地位、角色等,指物时侧重其作用、功能等;like则强调人或事物的外貌特征和性格特征的相像,或行为方式的相同。简言之，as表示一种事实，即“是”;而like则表示一种比喻，即“像”。例如：She spoke as a lawyer她作为律师发言。She spoke like a lawyer她讲话很像是律师。3表示动作方式一般用like。例如：他吃起东西来像头野兽。［误］ He ate as a beast［正］ He ate like a beast4表语词组一般由like引导,而不用as引导。conj(连词)as a matter of fact, as good as, as it is这三个短语都有“实际上，事实上”的意思，其区别是：as a matter of fact含有对比之意,说的是与已知的或已说过的内容不同的内容；as good as没有对比的意味，意思是“实质上差不多等于”；as it is则用于指出即将说的是一个事实。例如：Mike said he didn't tell a lieAs a matter of fact, he did迈克说他从没有说过谎。事实上,他说过。He as good as refused他实际上等于拒绝了。We had hoped to finish today,but as it is we probably won't finish until tomorrow我们原本希望今天能做完它，但实际情况是我们或许要等到明天才能做完。as, because, for, since这四个词都可以作连词引导一个表示原因的状语从句。其区别是：1because是从属连词,引导的原因状语从句指的是自然、直接的原因,主句表示必然的因果关系,而原因构成句子的主要部分,是句子的重点。另外,because引导的从句多放在句末,但有时也可放在句首,这种情况往往是为了强调。2如果原因很明显或已为人们所知,或不如句子的其余部分重要,就用as或since,since比as更正式一些,这两个词都为从属连词,常译为“由于,既然”,语气比because轻。as和since引导的句子多放在整个句子的开头,偶尔它们引导的(特别是since引导的)句子也可以放在后面。since作为理由有“不好”或“勉强”的含意;而as只将既成事实作为理由,并不含有“不好”或“勉强”的意味。3for是并列连词,引导的是并列从句,表示原因的语气很弱,一般是对结果作推断性的补充说明或解释,不表示直接原因。for较正式,很少用于口语,一般用于书面语,前面一般多用逗号。as it is/was, as it wereas it is/was是个短语，意思是“实际上”“事实上”“照目前情况来看”，用于把可能的情景与实际发生的情况进行对比；而as it were的意思则是“可以说是”“似乎是”“仿佛”，表示所说的话听起来不那么肯定。as, though这两个词用作从属连词引导让步状语从句时，都可采用倒装语序。其区别在于：as采用这种倒装语序是强制性的，而though则是非强制性的。此外，as引导的这种倒装语序还可表示原因，而though则无此功能。as, when, while这三个词都可作连词引导一个表示时间的状语从句。as引导的从句作“当…时”或“和…同时”解,从句中的动作与主句中的动作同时发生或同时进行,一般持续时间不长;when引导的从句作“当…时”或“每逢…”解,从句中的动作既可以和主句中的动作同时发生,也可以在主句的动作之前或之后发生;while引导的从句作“当…时”或“在…期间”解,它强调从句中的动作与主句中的动作同时发生,但持续时间一般较长或主句的动作在从句的动作过程中发生。while与as和when的最大区别在于有时含有“趁着…情况的存在赶紧做某事,否则来不及了”的意味。as well, also, besides, either, moreover, too这组词(组)都有“也,此外,还有”的意思。其区别是：also一般用于肯定句,有强调意味,位于主谓语之间,即实义动词之前,助动词之后; too只用于肯定句中,一般位于句末,比also更口语化; either一般只用于否定句,多位于句末; as well和too一样多用于口语,放在句末; besides与moreover词义基本相同,但moreover后面所叙述的,通常比前面所叙述更为重要或更深入一步,在词序方面, moreover往往用于句首,另外, moreover是较为正式的用语。例如:He also asked to go他也要去。I can also do it我也能干那个活。English is not easy, and French is not easy either英语不容易,法语也不容易。He is a teacher, and a writer as well他是个教师,也是个作家。I don't like those shoes; besides, they're too expensive那双鞋我不喜欢,而且也太贵。I don't like skating; moreover, the ice is too thin我不想去溜冰,再说冰层也太薄。The Opposition have consistently accused the Government of corruptionMoreover, they have named names反对党一直在指责政府腐败,而且是指名道姓的。下面两个句子的意思不同:We have a third as many students in our class as we had last term我们班的学生是上学期的三分之一。We have a third as many students again in our class as we had last term我们班的学生比上学期多了三分之一。as，because，for，since这些连词均含有“因为”之意。as从属连词，语意较because, since弱，着重在主句，所表示的原因或理由是“附带的”。because从属连词，语意强，着重直接的原因或理由，所引出的从句是全句的重心，用以回答why提出的问题。for并列连词，语气较弱，所引出的句子一般放在后面，表示附带说明的理由或推断理由。since语意比because弱，但比as强，一般用于表示“由于大家已知的事实”。as，like这两个词均有“像”之意。as从属连词，引出方式从句。like是前置词，后面跟的是宾语。though，although，as，even though这些连词均可表示“虽然，尽管”之意。though和although在意义上几乎毫无区别，但在习惯用法上这两个词仍有以下一些差异：1though可引出倒装语序的让步状语从句，although 则不能。2though可与even连用，although则不能；在as though结构中，只用though，不能用although。3though可以置于从句末，而although则不能。4引出省略句时，通常用though。although与though在意义上相似，但文体上是比较正式用词，语气比though强。as引出让步状语从句只用于倒装语序结构中，语气强于上述两个连词。even though（＝even if），意为“即使”，引导让步状语从句。though也引导让步状语从句，意为“虽然”；even though有退一步设想的意味，与though不同。though引导的句子所说的是事实，even though引导的句子所说的则不一定是事实。例如：when，while，as这些连词均可表示“当……时”引出时间从句。when所引导的从句，其谓语动词既可是持续动词，也可是短暂动词；谓语动词动作发生的时间可以与主句谓语动词的动作是同时，或之前、之后。while句中的谓语动词应为持续动词，不用短暂动词，谓语动作发生的时间通常与主句谓语动词动作发生时间是同时。as侧重指从句与主句的动作同时进行，谓语动词可以是持续性的，可以是短暂性动词。as的相关临近词

楼上在粘贴什么呢……

比较准确的方法是做个红外，通过谱图分析！

不过一般的用点燃也可以鉴别：

pvc在火焰上燃烧，离火熄灭，难以点燃，先软化，然后分解成棕黑色。

其余三个属于离火继续燃烧，易于点燃，软化变黑。

再继续鉴别：按塑料的透光性分，ps属于透明性塑料，abs属于不透明塑料，as属于半透明塑料。所以肉眼可以区分。
