Therefore, those companies that use non-woven bags as promotional gifts must not be greedy for small and cheap, and choose non-woven bag manufacturers with strong production technology and well-equipped, so as to extend the service life of the bags and reflect the value of environmental protection. . Non-woven bag is a green product, tough and durable, beautiful in appearance, good air permeability, reusable, washable, silk-screen advertising, marking, long service life, suitable for any company and any industry as advertising and gifts . The following is a non-woven bag manufacturer to introduce you to the relevant information of non-woven fabrics.
The price of non-woven bags is determined by its production cost.
Non-woven bag material: non-woven fabric is a kind of non-woven fabric, which directly uses polymer chips, short fibers or filaments to form a soft, breathable and flat structure through various web forming methods and consolidation technologies New fiber products. Non-woven bags have the characteristics of short process flow, high output, low cost, rapid variety change, and extensive sources of raw materials.
The advantages of non-woven shopping bags: The production is a green product, beautiful in appearance, and low in price. It is a better product for shopping and corporate image advertising.
Non-woven bags generally use the screen printing process, which is often referred to as "screen printing", which has always been a common printing process for many manufacturers. Usually it is printed manually, so the color control in the process is not easy to control, so many new non-woven printing methods have emerged. However, as customers continue to improve the degree of exquisite printing of products and the environmental protection requirements, many new non-woven fabrics have emerged The printing method, named after its use of water-based elastic glue as the printing medium, is more common in textile printing and is also called printing. Blend the color paste and water-based elastic glue when printing. No chemical solvents are used when washing the printing plate, and it can be washed directly with water. It is characterized by good tinting strength, strong covering and fastness, washing resistance, and basically no peculiar smell.
The finished products processed in this way are usually called laminated non-woven bags. This process is divided into two steps, that is, the traditional gravure printing process is used to print the image and text on the film, and then the film with the pattern is laminated on the non-woven fabric by the laminating process. Generally, non-woven bags printed with large-area color schemes use this process.
Regarding whether the non-woven bag is a hot press bag or a sewn bag, we can first look at the differences and advantages of the two types of bags.
Ultrasonic hot pressing bag: literally, it is a kind of non-woven bag that uses high temperature to press the non-woven fabric together. The current widespread method is to use ultrasonic pressure welding, which is a primary internal interconnection method, which is used to connect to the actual die surface or the primary internal interconnection method of the logic circuit of the device. This connection method combines logic signals or The electrical signal of the chip is connected to the outside world. Other primary interconnection methods include flip chip and tape-and-reel automatic soldering, but ultrasonic welding has an absolute advantage in these connection methods, and more than 90% of all interconnection methods use this method. About 90% of this figure uses gold wire ultrasonic welding, and the rest uses aluminum and other precious metals or materials similar to precious metals.
Sewing non-woven bags: Sewing non-woven bags are mainly stitched with sewing thread, which has better load-bearing capacity than ultrasonic heat-sealing bags, but the labor cost is higher than that of ultrasonic bags.
