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

　　什么是气泡膜？气泡膜是以高压聚乙烯为主要原料，再添加增白剂、开口剂等辅料，经高温挤出吸塑成气泡的产品。气泡膜是一种质地轻、透明性好、、无味的新型塑料包装材料，是用于包装填充的一种防压防潮防震的化工产品。具有良好的减震性、抗冲击性、热合性、、无味、防潮、耐腐蚀、透明度好等优点。

　　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.

　　现今各行各业的竞争力都越来越大，气泡膜厂家也是这样，再加上提倡资源的再生利用，很多气泡膜生产厂家开始使用新料与再生旧料夹杂进行生产的这种方式，在一定程度上增加的厂家的利润。但使用再生塑料生产的气泡膜，其白度和透明度往往不如人意，为能够解决再生塑料气泡膜的外观问题，可选择添加气泡膜用荧光增白剂来提升起泡膜的白度。

　　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.

　　气泡膜专用荧光增白剂可以使气泡膜增白、增亮，气泡膜属于软质的薄膜塑料，因此对荧光增白剂的分散性、稳定性以及透明度有着较高的要求。因此哲源生产的气泡膜专用荧光增白剂具有良好的分散性，可溶于有机溶剂中；稳定性好，可使气泡膜长期不发生迁移现象、不泛黄；白度值高，肉眼可见的提升气泡膜的白度和亮度，使产品外观更具竞争优势。

　　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.
