In various small and medium-sized shopping malls, supermarkets, and pet shops, we are more and more exposed to a new kind of packaging bag—spout pouch china, such as liquid packaging, seasoning packaging, laundry detergent packaging and so on. The spout pouch is composed of a spout and a stand-up pouch. In production, the production of the spout pouch is completed through two steps: bag making and spout bag loading. Every link has high requirements on the process. If it is not well mastered, there will be quality problems such as bag expansion, bag breakage, and leakage during use. Therefore, such spout pouch china is unqualified, so in spout pouch How to avoid such a situation during the production process in China?
First of all, in the production of stand-up pouches, special attention should be paid to the steps of punching, placing the bottom of the bag, heat sealing the bottom, etc., especially the combination of the four-layer and two-layer stand-up pouches is prone to bag breakage, and the horizontal sealing knife alone is not enough. It is necessary to install a heat-sealing knife, and some parts also need to strengthen the heat-sealing. In addition, stand-up bags with mouths require better opening performance, otherwise the suction cup will not be easy to pull the mouth to install the mouth; the friction coefficient of the bag surface should be small, and the surface static electricity should be removed when making bags to avoid adsorption between bags, which is not conducive to loading The mouth sealer takes the bag. At present, there are mainly two methods for installing nozzles in stand-up pouches: manually installing nozzles and heat-sealing nozzles. The temperature is transferred to the mouth through the heat conduction method, so that the mouth melts and is welded together with the PE sealing layer of the bag.
