Self-Sealing Bag Making MachineThis industry has a bright future because it offers many benefits to businesses, making it very popular with customers. To help you understand it better, let's discuss the key points for using self-sealing bag making machines. Hopefully, this will be helpful.

Nowadays, many peopleSelf-Sealing Bag Making Machinelack basic knowledge of self-sealing bag making machines. Therefore, as a manufacturer, we need to explain it briefly. Essentially, a self-sealing bag making machine sprays high-pressure fine water streams onto one or more layers of fiber webs, causing the fibers to intertwine and strengthen the web, giving it a certain level of strength. Common methods involve adding fibrous or powdery hot-melt adhesive reinforcing materials to the fiber web, then heating, melting, cooling, and consolidating the fiber web into fabric. Air-laid non-woven bags: Also known as dust-free paper or dry-laid non-woven fabric. It uses air-laid technology to loosen wood pulp fiber boards into single fibers, then uses air-laid methods to condense the fibers onto a forming screen, and then strengthens the fiber web into fabric. Here's another way: Wet-laid non-woven bags: The fiber raw materials in an aqueous medium are opened into single fibers, while different fiber raw materials are mixed to form a fiber suspension pulp, which is transported to the forming mechanism. In this state, it is formed into a web and then consolidated into fabric. Additionally, after being extruded and stretched into continuous filaments, the filaments are laid into a fiber web, which is then converted into non-woven fabric using self-bonding, heat bonding, chemical bonding, or mechanical consolidation methods. Specifically, melt-blown non-woven bags: The process flow includes polymer feeding, melt extrusion, fiber formation, fiber cooling, web forming, and consolidation into fabric.

Self-Sealing Bag Making MachineScreen printing, also known as silk screen printing, has been a common printing method used by many manufacturers. It's usually done manually, making color control difficult, leading to the development of new non-woven fabric printing methods. Additionally, the name comes from using water-based elastic glue as the printing medium. It's often used in textile printing and is also called printing. During printing, the color paste is mixed with water-based elastic glue. No chemical solvents are needed for printing; simply wash with water. It features good coloring power, strong opacity and firmness, water resistance, and is basically odorless. Therefore, finished products processed using this method are usually called laminated non-woven bags. This process involves two steps: traditional gravure printing is used to print graphics onto the film, and then the film with the pattern is laminated onto the non-woven fabric using a self-sealing bag making machine. Some non-woven bags use this process to print large, colorful patterns. Its advantages include exquisite printing, fully automated production, and short production cycles. Furthermore, these self-sealing bag making machines provide good waterproof performance, and the finished products are more durable than those made using other processes. The film has both glossy and matte options; matte has a frosted effect! The disadvantage is a conflict with environmental principles because the film is not easily biodegradable.

What are the advantages of self-sealing bag making machines?

There are many types of packaging machines. With the improvement of people's living standards and the rise of the post-90s and post-00s generations, fewer young people are willing to work in factories. It is becoming increasingly difficult for factories to recruit workers; moreover, with the rising labor costs, employee wages are becoming a significant burden for enterprises. Below, we will introduce the advantages of self-sealing bag making machines.
