  塑料食品包裝的多樣性,和大量的包裝是透明的,這樣我們就能讓客戶清楚地看到里面的食物,也可以清楚食物腐敗,透明的塑料,是塑料制造商想要,但有一些食品包裝無毒環保,達到食品級,食品包裝大多在PC材料的形式。如何將黃色塑料變成透明的,今天為您推薦一款黃色代理rqt-k-1升級。塑料彩票网站代理加盟群
  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

  近年來,為了改善食品衛生,減少環境污染,我國十分重視以天然高分子材料為原料,制備環保型、可生物降解的新型包裝材料。預計在不久的將來,可以回收和環保的包裝材料將成為包裝行業的發展的主要趨勢,綠色包裝材料和納米包裝材料將大力開發和發展,這樣一方面可以減少環境保護的壓力,比較能直接降解的塑料制品,分為無機,另一方面可以減少塑料所消耗的能源生產。目前,常用的還是塑料制品,根據五種一般塑料的基本性能,市場上使用較多的是PC塑料,PC幾乎是無色的玻璃非晶聚合物,具有良好的光學性能。PC高分子樹脂具有高韌性,懸臂梁缺口的沖擊強度為600~900J/m,未填充品牌的熱變形溫度約為130℃,玻璃纖維增強可將該值提高10℃。PC彎曲模量可達2400MPa以上,樹脂可加工成大型剛性制品。在100℃以下,荷載作用下蠕變率非常低。塑料彩票网站代理加盟群
  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,不能用于重復高壓蒸汽的產品。PC的主要性能缺陷是耐水解穩定性不高、對缺口敏感、耐有機化學、耐劃痕性差、長期暴露于紫外線下會發黃。與其他樹脂一樣,pc易受某些有機溶劑的影響。比較重要的是,PC塑料用于食品包裝,隨著時間的推移,黃色,如何解決黃色市場黃色添加劑的問題大多是光亮劑,一個黃色的代理等等,這種添加劑有缺陷是缺少食品級別,重金屬超標、食品級測試沒有關閉,這種添加劑大多數制造商都選擇放棄,或尋找使用添加劑。彩票网站代理加盟群廠家
  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.
