With the improvement of people's living standards, the types of goods that people consume are also increasing. The increase in consumer goods has also promoted the development of the product packaging equipment industry. The current market development prospects for paper bag machines are very good, because many products require paper bag packaging. Now that the demand for paper bags in the market is increasing, the paper bag machine equipment also needs to be reformed and developed to meet the market demand.
Now we can also see the development direction of food packaging machinery, which is moving in the direction of high-speed, multi-function and intelligent control to meet market demand. In order to meet the requirements of the delivery time and reduce the cost of process circulation, the future food packaging machinery requires high-speed production. At the same time, for some products, packaging machinery and production machinery are required to be connected, and continuous work or multi-head work can also be used.
In addition, it is necessary to reduce the rejection rate and failure rate to increase the normal productivity. The development trend is to make the packaging machinery more intelligent.
Packaging machinery pursues the integration of packaging and processing. There are many new packaging technologies based on new packaging thinking. New packaging thinking means going beyond the existing packaging technology and products, and applying other related technology combinations to packaging to form a new packaging technology, including packaging cutting and molding technology, packaging curing technology, packaging function protection technology, packaging and processing Combining technology and packaging function to borrow technology.
If we want the paper bag machine industry to get a better development, we must first know where our weaknesses are and what our needs are. As long as we have clear goals, we can move forward better. We believe that with the continuous expansion of the domestic food industry market, the requirements for domestic packaging products have been greatly increased, so that it can better stimulate the production of automated and intelligent high-end packaging equipment by paper bag machine companies everywhere.

The kraft paper made by our common kraft paper bag machine is generally yellowish brown, and it is often used to make bags and wrapping paper. There are many types of kraft paper on the market. According to the nature and use of kraft paper, we can often classify it. According to different classifications, it will be easier for us to find the kraft paper we need.
1. Kraft paper usually keeps its yellowish-brown color, suitable for bags and wrapping paper. Depending on its properties and uses, kraft paper has various uses. Kraft paper is a collective name for a kind of paper, and there is no certain specification, and it is generally classified according to its nature and use.
2. According to the different colors, it can be divided into: primary color kraft paper, red pine kraft paper, white kraft paper, flat kraft paper, single-gloss kraft paper, and two-color kraft paper.
3. According to different purposes, it can be divided into: packaging kraft paper, waterproof kraft paper, moisture-proof kraft paper, anti-rust kraft paper, pattern-making kraft paper, process kraft paper, insulation kraft paper, and kraft stickers.
4. According to different materials, it can be divided into: recycled kraft paper, kraft core paper, kraft base paper, rough kraft paper, kraft wax paper, wood pulp kraft paper, composite kraft paper. Kraft paper color reasons
Different sources of kraft paper raw materials, different production batches, different production seasons, different production machines, etc. Many reasons will affect the color of the kraft paper roll base paper. This difference in color is difficult to avoid, and it is also Uncontrollable, generally the same batch of kraft paper can guarantee 98% consistent color. Kraft paper applications and uses
1. Kraft paper is used in various industries such as chemical industry and machinery, especially widely used in food packaging industry. Kraft paper is widely used in various packaging supplies, such as paper bags, handbag kraft paper, color boxes, paper cups, gift box kraft paper, printing kraft paper, notebook kraft paper, workbook kraft paper, and special kraft paper for envelopes.
2. Food packaging should follow the principle of convenience and convenience. The tensile strength of kraft paper makes it very suitable for packaging needs. In order to prevent the bag from being pulled off when consumers carry out food, the packaging material is required to have good tensile strength. Beverage packaging requires that the material has a certain resistance to moisture and deformation to prevent deformation and damage due to water absorption.
3. We packed 2 books in a carrying bag. The weight of the two books is 2kg. The bearing capacity is still OK, the bottom is not broken, and the handle is not broken. The glue we use to make paper bags
It consists of two parts: base material and adhesive. The adhesive material is mainly hot melt adhesive, pressure sensitive adhesive, acrylic adhesive, synthetic rubber, natural rubber, etc. The base materials include polypropylene film, polyvinyl chloride film, fiber cloth, fiber plastic, sponge, foam, tissue paper and other materials. But the glue used in our craft is hot melt glue, which belongs to glue used for food grade paper bags.

The roll paper square bottom paper bag machine is to finish the original color or printed roll paper through edge coating, folding into a tube, paper tube cutting, bottom folding, bottom coating, bag bottom forming, and finished bag output in one time. The machine is controlled by a PC servo control system, touch screen man-machine interface real-time display, and can produce paper bags of various specifications.

Automatic roll paper square bottom paper bag machine uses base paper or printed roll paper as raw materials to complete square bottom paper bags with handles simultaneously. It is an ideal equipment for producing square bottom paper bags with handles. The machine uses the handle component to make the paper rope and the patch roll paper into a handle, and then sends the handle to the sticking unit through a conveying device.
After the sticking unit cuts the original color or printed roll paper at the sticking position, gluing the sticking position, and automatically sticking the handle, the host machine will glue the paper with the handle to form a paper tube. , Cutting, bottom indentation, bottom coating, bag bottom forming and conveying out of the bag.
The whole machine is controlled by the computer central control system, the running status is displayed and controlled by the touch screen, and the length of the bag is controlled by the servo motor, which ensures that the machine can produce various specifications of portable paper bags.
