When processing paper bags, not only printing is needed, but also paper bag machines. The printed products can be processed on the paper bag machine to produce usable paper bags. So, how are the various paper bags that we see in our daily lives made?
Next, the editor will give you an introduction. When making paper bags, you must first buy the paper used to make the paper bags. The next thing to do is to design according to the customer's requirements, and then print the content of these designs on the paper, and then process the film and bronzing after production. The most important thing is to use a paper bag machine to process and produce. It can replace manual production, thereby reducing labor, improving work efficiency, and making the quality of the paper bag stronger and better. These are the production processes of a paper bag.

the reason:
(1) The heat sealing temperature is too high;
(2) Excessive pressure;
(3) The hot air time is too long;
(4) The edge of the upper sealer is too sharp or the coated PTFE is damaged;
(5) The silicone rubber at the bottom seal is too hard;
(6) During the compounding and curing process, part of the adhesive penetrates into the film. Due to the penetration of the adhesive, the toughness (impact resistance) of the substrate has decreased and the brittleness has increased;
(7) After the plastic composite packaging bag is cooled and placed, the heat-seal strength is enhanced, and it also tends to become brittle.
Countermeasures:
(1) According to the heat sealing characteristics of the material of the inner sealing layer, select the appropriate processing temperature, pressure and heat sealing time;
(2) Improve the surface condition of the upper heat sealing knife and make the surface of the sealer flat;
(3) The coating is intact with PTFE;
(4) Choose a silicone rubber pad with appropriate hardness.

The development of tote bags from a means of transportation to a media for information dissemination is relatively late in our country, but China has been making handbags since ancient times: Whenever New Year’s The corners are tied into a knot to make a simple tote bag, which is filled with sumptuous New Year goods, to celebrate the New Year with friends and relatives. In normal times, he uses linen to make durable linen bags, puts on a change of clothes and utensils, and visits distant places to visit relatives and work. Even in today’s society, there are still many traditional and rustic handbags. The handbags used to hold the thread balls when the housewife knits sweaters, or the woven bags used to hold personal items after work are more Typical design form of handbag.
According to different purposes: including file bags, envelopes, handbags, cement bags, feed bags, wax paper bags, fertilizer bags, laminated paper bags, four-layer paper bags, medicine bags, clothing bags, food bags, shopping bags, gift bags, wine bags ,. Different uses. The designed specifications and sizes, including the thickness of the paper bag paper, have many requirements, so they should be customized according to the actual situation to achieve the purpose of double the result with half the effort and economical application. It provides more protection for material reduction, environmental protection, and corporate capital investment. .
Packaging machinery is a comprehensive science, which involves a variety of disciplines such as materials, technology, equipment, electronics, electrical appliances, and automatic control. It requires the development of related disciplines in a synchronized and coordinated manner. Any subject matter will affect the overall packaging machinery. performance. Therefore, the development of packaging machinery will effectively promote the progress of related disciplines. In addition, in order to meet the needs of high-speed packaging by packaging machinery, the related front and back processes are bound to adapt to it, which also promotes the simultaneous development of related processes.

The kraft paper bag machine is a new generation of multi-layer kraft paper bag making machine designed to solve environmental pollution and comply with the environmental protection. It can be used to make bags of 70-140 grams of kraft paper rolls. The machine is simple and convenient to operate. It can produce foldable bags, non-folded bags, single-layer packaging bags or multi-layer packaging bags of different bag types.
The kraft paper bag machine unit is equipped with advanced electrical systems and mechanical devices in the entire process from substrate delivery, tube formation, edge gluing, bag cutting, and bag conveying. The whole process is equipped with advanced electrical systems and mechanical devices, using a servo system combined with a man-machine interface. The feeding of the substrate to the finished bag is continuously completed in one process, with a high degree of automation.
The bag-making technology is advanced, the equipment structure is reasonable, and the tube bag is beautiful and reliable. It is an ideal equipment for various bag-making enterprises at home and abroad to produce various types of packaging bags.

Fully automatic paper bag quantitative packaging machine, in a metal cabinet with upper and lower layers, the upper left column screw fixes the bag storage mechanism; opposite to the outlet of the paper bag is the bag taking mechanism; the terminal of the bag feeding mechanism faces the bag opening mechanism and opens The bag mechanism is the equipment of the first range space of the rotating disk; the rotating disk is divided into eight equal range spaces according to the circumferential angle; each space is equipped with a pair of bag clamping clips and the lower bag holder; the corresponding range space position is also Equipped with quantitative filling, tapping, and closing equipment; the next connection is the lower linear conveying and the upper corresponding sealing equipment; the trimming, folding, rolling, bonding and compacting equipment are arranged in a straight line; and through The transmission and palletizing mechanism is connected with the film heat shrink packaging machine; the lower layer of the cabinet is installed, the transposition cam, the feeding cam, the camshaft cam; the pneumatic control and the electric control board are on the side of the cabinet, and the quantitative filling mechanism is set on the cabinet to provide interference feeding The system and the dust suction pipeline are connected; the entire packaging process is fully automatic flow operation, with high automation, accurate measurement, fast packaging speed, and small damage and dust pollution.
