According to market research feedback, nowadays milk tea, hotel and tourist products, and cosmetics are particularly suitable for manual sealing machines, which are small and light, with fast bonding speed. Some of the high-end and beautiful manual sealing machines have become one of the necessary equipment for sealing. Now we will further elaborate on what factors may cause the manual sealing machine to fail to seal:
1. The heat seal is too dirty or has carbide-like foreign matter
According to many survey feedbacks, manual sealing machines have been used in many application fields due to their advantages of high efficiency, energy saving and fast sealing speed in recent years. However, when human operation errors occur, the manual sealing machine may not be able to seal, such as the heat seal is too dirty or there are other impurities such as carbides, then the viscosity of the seal will be greatly reduced.
2. Excessive heat in the packaging bag leads to failure of the hot press seal
If the heat in the packaging of the manual sealing machine is too high, the too high heat will continue to evaporate in the bag, which will easily cause the temperature of the seal to continue to rise. At this time, it is recommended that the user take appropriate cooling measures for the packaging bag first, and when the heat in the packaging bag returns to room temperature, start the manual sealing machine to heat and press the film layer, so as to ensure a better sealing effect.
3. Improper selection of packaging bags
The manual sealing machine is suitable for most packaging bags, but some special types of packaging bags cannot be manually sealed. For example, when choosing a vacuum packaging machine or an externally pumped vacuum packaging machine, you must consider the requirements of the corresponding packaging bag. At this time, forcing the sealing will cause the sealing effect to be poor or the sealing will not stick.
The application of manual sealing machine is in many different industries such as pharmacy, food and chemical industry. Especially those emerging manual sealing machines have become classic hot-push items. According to relevant feedback, the reason why the manual sealing machine cannot be sealed is not only because the heat seal strips are too dirty or there are carbides, but also possible Because the heat in the packaging bag is too high, the heat-pressing seal fails and the packaging bag selection is improper.
