如何对蔬菜包装箱进行防潮处理?

来源:https://www.gtmfpack.com 发布时间:2022-02-19

虽然包装纸箱有很好的性能,他们是相对脆弱的。一旦纸箱遇水,就会失去原来的性能。因此,很多厂家都会对纸箱进行防潮处理。如何对纸箱进行防潮处理?考虑到效果和成本,通常采用以下方法:
Although packaging cartons have good performance, they are relatively fragile. Once the carton meets water, it will lose its original performance. Therefore, many manufacturers will carry out moisture-proof treatment on cartons. How to damp proof the cartons? Considering the effect and cost, the following methods are usually adopted:
添加防水剂:一般情况下,厂商对纸箱的防潮处理是在纸箱外面涂一层防水剂。这种方法简单,成本低。能给纸箱带来良好的防潮效果,根据需要可分为临时防水处理和长期防水处理。
Add waterproof agent: generally, the manufacturer's moisture-proof treatment for the carton is to apply a layer of waterproof agent on the outside of the carton. This method is simple and low cost. It can bring good moisture-proof effect to the carton. It can be divided into temporary waterproof treatment and long-term waterproof treatment according to needs.
覆膜工艺的使用:覆膜是纸箱面纸、纸箱、手袋、封面等印刷品常用的防水处理工艺。印刷品经层压后可达到防水、防污、防褪色、耐热、耐光、耐冲突的性能。这种处理不仅能给纸箱带来优越的防水性能,而且能提高纸箱强度和抗拉强度的光泽度和撕裂度,提高纸箱的使用寿命和包装质量。
Use of film coating process: film coating is a commonly used waterproof treatment process for printed materials such as carton paper, carton, handbag and cover. After lamination, the printed matter can achieve the performance of waterproof, antifouling, anti fading, heat resistance, light resistance and conflict resistance. This treatment can not only bring superior waterproof performance to the carton, but also improve the gloss and tear of the carton strength and tensile strength, and improve the service life and packaging quality of the carton.
添加高分子聚合物:目前在瓦楞纸箱的生产过程中,添加适量的高分子聚合物(又称交联剂或架桥剂)在淀粉粘合剂中,高分子聚合物将取代淀粉分子中的羟基,使瓦楞糊线具有较好的防水防潮效果。当纸箱进入冷库或潮湿环境时,可防止瓦楞糊线吸湿乳化造成纸箱倒塌。
Add high molecular polymer: at present, in the production process of corrugated box, add an appropriate amount of high molecular polymer (also known as crosslinking agent or bridging agent) in the starch adhesive. The high molecular polymer will replace the hydroxyl group in the starch molecule, so that the corrugated paste line has a good waterproof and moisture-proof effect. When the carton enters the cold storage or humid environment, it can prevent the corrugated paste line from moisture absorption and emulsification, resulting in the collapse of the carton.
避免原材料受潮:如果纸箱的原材料在生产过程中已经受潮,会对后续加工生产的包装纸箱产生很大影响。因此,大多数纸箱厂会尽量将原纸仓库与外界隔离,保证相对温度低,保障原纸质量。
The raw materials of cartons will be greatly affected if they are damp in the subsequent production process. Therefore, most carton factories will try to isolate the base paper warehouse from the outside world to ensure the relative low temperature and ensure the quality of base paper.
