  塑料食品包装的多样性,和大量的包装是透明的,这样我们就能让客户清楚地看到里面的食物,也可以清楚食物腐败,透明的塑料,是塑料制造商想要,但有一些食品包装无毒环保,达到食品级,食品包装大多在PC材料的形式。如何将黄色塑料变成透明的,今天为您推荐一款黄色代理rqt-k-1升级。塑料荧光增白剂
  Plastic food packaging diversity, and a large number of packaging is transparent, so that we can let customers clearly see the food inside, but also clear food corruption, transparent plastic, plastic manufacturers want, but some food packaging is non-toxic and environmentally friendly, up to the food level, food packaging mostly in the form of PC materials. How to make yellow plastic transparent? Today we recommend a yellow agent rqt-k-1 upgrade. Plastic fluorescent whitening agent

  近年来,为了改善食品卫生,减少环境污染,我国十分重视以天然高分子材料为原料,制备环保型、可生物降解的新型包装材料。预计在不久的将来,可以回收和环保的包装材料将成为包装行业的发展的主要趋势,绿色包装材料和纳米包装材料将大力开发和发展,这样一方面可以减少环境保护的压力,最能直接降解的塑料制品,分为无机,另一方面可以减少塑料所消耗的能源生产。目前,常用的还是塑料制品,根据五种一般塑料的基本性能,市场上使用较多的是PC塑料,PC几乎是无色的玻璃非晶聚合物,具有良好的光学性能。PC高分子树脂具有高韧性,悬臂梁缺口的冲击强度为600~900J/m,未填充品牌的热变形温度约为130℃,玻璃纤维增强可将该值提高10℃。PC弯曲模量可达2400MPa以上,树脂可加工成大型刚性制品。在100℃以下,荷载作用下蠕变率非常低。塑料荧光增白剂
  In recent years, in order to improve food hygiene and reduce environmental pollution, China attaches great importance to the preparation of environmentally friendly and biodegradable new packaging materials using natural macromolecule materials as raw materials. It is expected that in the near future, recyclable and environmentally friendly packaging materials will become the main trend of packaging industry development. Green packaging materials and nano-packaging materials will be vigorously developed and developed. On the one hand, the pressure of environmental protection can be reduced. Plastic products which can be degraded most directly can be classified into inorganic ones, on the other hand, energy consumption of plastics can be reduced. At present, plastic products are still commonly used. According to the basic properties of five kinds of plastics, PC plastics are mostly used in the market. PC is almost colorless glass amorphous polymer, which has good optical properties. PC macromolecule resin has high toughness. The impact strength of notch of cantilever beam is 600-900J/m. The thermal deformation temperature of unfilled brand is about 130 C. Glass fiber reinforced can increase this value by 10 C. PC bending modulus can reach more than 2400 MPa, resin can be processed into large rigid products. The creep rate is very low under the action of load below 100 C. Plastic fluorescent whitening agent
  PC耐水解性差,不能用于重复高压蒸汽的产品。PC的主要性能缺陷是耐水解稳定性不高、对缺口敏感、耐有机化学、耐划痕性差、长期暴露于紫外线下会发黄。与其他树脂一样,pc易受某些有机溶剂的影响。最重要的是,PC塑料用于食品包装,随着时间的推移,黄色,如何解决黄色市场黄色添加剂的问题大多是光亮剂,一个黄色的代理等等,这种添加剂有缺陷是缺少食品级别,重金属超标、食品级测试没有关闭,这种添加剂大多数制造商都选择放弃,或寻找使用添加剂。荧光增白剂厂家
  PC has poor hydrolysis resistance and can not be used for products with repeated high pressure steam. The main performance defects of PC are low hydrolysis stability, sensitivity to notch, resistance to organic chemistry, poor scratch resistance and yellowing after long-term exposure to ultraviolet light. Like other resins, PC is susceptible to some organic solvents. Most importantly, PC plastic is used in food packaging. Over time, yellow, how to solve the problem of yellow additives in the Yellow market is mostly brightener, a yellow agent and so on. The defects of this additive are lack of food grade, excessive heavy metals, food-grade testing has not been closed. Most manufacturers of this additive choose to give up or look for additives.
