Speaking of bubble film, you should be familiar with it. Some of the things we buy online will use bubble film, also known as air cushion film, in order to prevent moisture, buffer, heat preservation, earthquake resistance and other functions of the products when they are mailed and packed. We can see that the bubble film is white and bright, which is attributed to the fluorescent brightener

　　什么是氣泡膜？氣泡膜是以高壓聚乙烯為主要原料，再添加增白劑、開口劑等輔料，經高溫擠出吸塑成氣泡的產品。氣泡膜是一種質地輕、透明性好、無毒、無味的新型塑料包裝材料，是用于包裝填充的一種防壓防潮防震的化工產品。具有良好的減震性、抗沖擊性、熱合性、無毒、無味、防潮、耐腐蝕、透明度好等優點。

　　What is a bubble film? Bubble film is a kind of product which is made of high-pressure polyethylene as the main raw material, and then added with whitening agent, opening agent and other auxiliary materials, and extruded into bubble by high temperature. Bubble film is a new type of plastic packaging material with light texture, good transparency, non-toxic and tasteless. It is a kind of chemical product which is used for packing and filling. It has the advantages of good shock absorption, impact resistance, heat sealing, non-toxic, tasteless, moisture-proof, corrosion resistance, good transparency, etc.

　　現今各行各業的競爭力都越來越大，氣泡膜廠家也是這樣，再加上國家提倡資源的再生利用，很多氣泡膜生產廠家開始使用新料與再生舊料夾雜進行生產的這種方式，在一定程度上增加的廠家的利潤。但使用再生塑料生產的氣泡膜，其白度和透明度往往不如人意，為能夠解決再生塑料氣泡膜的外觀問題，可選擇添加氣泡膜用熒光增白劑來提升起泡膜的白度。

　　Nowadays, the competitiveness of all walks of life is growing, so is the bubble film manufacturers. In addition, the country advocates the recycling of resources. Many bubble film manufacturers begin to use the way of mixing new materials with recycled old materials for production, to a certain extent, increasing the profits of manufacturers. However, the whiteness and transparency of the bubble film produced by recycled plastics are often unsatisfactory. In order to solve the appearance problem of the bubble film, we can choose to add the bubble film with fluorescent brightener to improve the whiteness of the bubble film.

　　氣泡膜專用熒光增白劑可以使氣泡膜增白、增亮，氣泡膜屬于軟質的薄膜塑料，因此對熒光增白劑的分散性、穩定性以及透明度有著較高的要求。因此哲源生產的氣泡膜專用熒光增白劑具有良好的分散性，可溶于有機溶劑中；穩定性好，可使氣泡膜長期不發生遷移現象、不泛黃；白度值高，肉眼可見的提升氣泡膜的白度和亮度，使產品外觀更具競爭優勢。

　　The special fluorescent brightener for bubble film can whiten and brighten the bubble film. The bubble film belongs to soft film plastic, so it has higher requirements for the dispersion, stability and transparency of the fluorescent brightener. Therefore, the special fluorescent brightener for bubble film produced by Zeyuan has good dispersibility and can be dissolved in organic solvent; it has good stability and can prevent the bubble film from migrating and yellowing for a long time; the whiteness value is high, which can be seen by the naked eye to improve the whiteness and brightness of the bubble film and make the product more competitive in appearance.
