Process flow and material thickness selection of non-woven bag making machine


The non-woven bag making machine feeds the powder (colloid or liquid) from the feeder to the hopper above the packaging machine. The introduction speed is controlled by the photoelectric positioning device, and the roll of sealing paper (or other packaging materials) is passed through. The guide roller is driven to be introduced into the lapel former, which is bent and then lapped into a cylindrical shape by the longitudinal sealer. The material is automatically metered and filled into the finished bag, and the transverse sealer is used for heat sealing and cutting. The cylinder is pulled downward intermittently, and finally a flat bag of three-side sealing of the longitudinal joint is formed to complete the sealing of one bag.

When we make a custom-made non-woven tote bag, we should first know that the material specification of the non-woven tote bag is calculated in grams (g). Under normal circumstances, the market's non-woven green shopping bags are mostly 70-90g, so how to accurately choose the custom thickness?

First of all, it is necessary to clarify that different thickness bearing capacities are different. A 70g bag generally has a load of about 4kg. 80g can be around 10Kg. More than 100g can bear about 15kg. Of course, according to the production process. Ultrasonic is about 5kg. Sewing and fork reinforcement can maximize the load-bearing performance of the fabric. Therefore, different industries and uses can choose different thicknesses depending on the cost. If it is the inner packaging of the clothing and shoes, 60g will be fine. For the outer packaging of small commodities and the use of advertising non-woven bags, 70g can also be used. However, due to quality and aesthetic considerations, it is generally not going to save this cost. If the food or larger product exceeds 5kg, more than 80g of fabric is recommended, and the manufacturing process also requires sewing.
