  天气逐渐变冷,大家购买早餐时会发现摊贩将塑料包装好的豆浆或者牛奶泡在热水里,这样在我们饮用的时候就会是温的;如果大家买的食品或者饮料有些凉有些人也会选择放入微波炉稍微加热,但是许多塑料包装的食品在加热之后会隐隐的有种塑料味,这些是否就是传说中的塑化剂或者其他添加剂,是否对人体有害呢?
 
    对此,南京大学化学化工学院的陆云教授介绍,一般装食物的塑料制品都是聚乙烯和聚丙烯,他们被泡在水中加热应该来说是安全的。同时,很多装食品的塑料制品中还会添加一些别的添加剂,比如脱模剂和润滑剂,在高温中,一些成分比较活跃的添加剂可能会分解出来,但是这个高温不可能是我们热水泡的时候100℃都不到的温度。
 
    近两年,中国饮料市场上的新包装逐渐多了起来,目前,用于饮料包装的塑料种类主要有几种:
 
     1、PE(聚乙烯):
 
    PE是世界上产量大的合成树脂,也是消耗量大的塑料包装材料。聚乙烯产品又分为低密度、中密度和高密度三种。其中高密度聚乙烯(HDPE)因具有较高的结晶度,其硬度、气密性、机械强度、耐化学药品性能都较好,所以被大量采用吹塑成型制成瓶子等中空容器。利用PE热封性能好的特点,生产的各种复合材料制成的容器,可盛装柠檬汁、果汁等各种饮料。
 
     2、PVC(聚氯乙烯):
 
     PVC大致可分为硬制品、软制品和糊状制品三类。用注拉吹法生产的PVC瓶无缝线,瓶壁薄厚均匀,可盛装含气饮料如可乐、汽水等;采用挤出吹塑法生产的PVC瓶只适用于盛装果汁和矿泉水。
 
     3、PP(聚丙烯):
 
     聚丙烯透明包装瓶的开发是近几年国内外塑料包装的一个热点。随着透明改性剂——成核剂的开发成功,在普通PP中加入0.1%——0.4%山梨醇缩二甲苯(苯甲醛)成核剂,所生产出来的高透明PP瓶可广泛用于需热杀菌如浓缩果汁等需要高温灌装的饮料包装中,其价格适宜、耐压抗温,是PS、ABS、PET、PE瓶的新生对手。
 
    4、聚酯(PET或PETP):
 
     采用二轴延伸吹塑法生产的PET瓶,具有良好的透明度,表面光泽度高,呈玻璃状外观,是代替玻璃瓶合适的塑料瓶。近年来,我国PET瓶生产发展迅速,广泛应用于各种茶饮料、果汁等需要热灌装的饮料,如百事可乐公司600ml、1.25L、2L及2.5L的PET瓶,不同的容积针对个人、家庭的不同需求,受到广大消费者的好评。
 
    目前早点摊上使用的大都是透明状、价格低廉的薄膜塑料袋,多以PVC(聚氯乙烯)为原料加工而成,多数是再生材料。这种含有聚氯乙烯的塑料袋,遇到高温会释放出铅等有毒物质。当温度超过50℃时,塑料袋里面的有毒成分就会渗出,从而污染食物,对人体造成危害。当温度达到80℃,会遇热熔解,释放出有毒害的物质来。热(熟)食温度都在40℃以上,而刚炸出来的油条和刚出锅的豆浆,温度大约有90℃。
 
    其实,日常使用中如果使用符合标准的接触性塑料袋是可以避免这些困扰的,但是市民但市民还是尽可能不要用塑料袋装高温及含油的食品,过热的食品也要先等凉下来再装,在日常生活中正确使用就不会对身体造成危害。
