Small bags are mostly used to contain liquids, powders, small particles, large particles of products, the material of small bags is no different from the conventional bags. But the smaller the size of the bag is not good to do, we all know that any machine and equipment are tolerances, so the process of bag making must require a very high precision, otherwise, the bad rate will be greatly increased, the material loss is huge.
Vacuum packaging bags, tea bags Considering the operational difficulties of small bags in the process of bag making and filling, it is recommended that the use of roll film is better, which can save a bag making process, thus avoiding the loss. Price roll film is accounted for by the kilogram, generally 20 to 40 a kilogram, the specific can contact the packaging bag manufacturer for accounting. And small bags are accounted for by the starting quantity, in the size of 30 * 80mm, for example, the starting quantity is about 300,000, its price is about 10 cents. In the same volume of raw materials, the number of bags made of roll film is higher than the number of bags made directly, so it is clear who is better and who is worse.
Customers who are doing roll film for the first time may have a question: How do you make bags from roll film? The process of making bags from rolled film is done by automatic packaging machines, and we mark the rolled film with an electric eye position for easy identification. This way the packaging machine can fill the product while making the bag, which greatly improves the production efficiency.
