Carton production process

1 The design determines the final effect of the product

The design is particularly important for carton products, otherwise it is difficult to meet customer requirements. The marketing department transmits all the information of the customer to the process design department. It includes the decoration requirements of the layout, the size of the specification, the box structure, the contents and weight, the number of stacking layers and other related content. After being designed by the design department, it can be transmitted to the manufacturing department to complete the realization of the product.

1) Calculate the maximum stacking load Ps that the lowest carton can bear

i.e. Ps=(Nmax-1)· G, where Nmax is the maximum number of stacking layers, and G is the contents and box weight.

2) Select the appropriate safety factor K

According to the requirements of SN/T0262-93 export transport packaging corrugated box inspection procedures, when the storage period is less than 30 days, K = 1.6; When the storage period is 30~100 days, K=1.65; When the storage period is greater than 100 days, K = 2.

Of course, for the sake of safety, the safety factor is usually taken above 3. However, the safety factor is too large, the various indices of raw materials are relatively high, and the price of paper will rise significantly, resulting in an increase in costs, which is not conducive to market development. In addition, if the safety factor is too large, there will be excess quality, and the coefficient is too small, which will cause quality problems such as collapsed boxes. Therefore, it is necessary to select the appropriate safety factor according to the actual requirements of customers.

3) According to the safety factor, calculate the maximum compressive strength value P to be achieved

即P=K· Ps

4) According to the Kelicutt formula, choose the appropriate paper combination

i.e. Px· F=P(calculated)

Therefore, Px=P/F, where F is a constant related to the length of the carton perimeter and the corrugated type, which is obtained by looking up the table. Px is the comprehensive ring compressive strength value of corrugated cardboard, Px=(R1+R2+Rm1C)/15.2

If the ring pressure index and gram weight of any one or two materials in R1, R2 and Rm1C are known, the ring pressure index and gram weight of the third material can be found to achieve the purpose of reasonable matching of paper.

2. Doing a good job in process control is the guarantee of product realization

Whether the products designed by the process technology department can be well implemented, each process is very important to the strict implementation of the standard. Therefore, the squad leader of each process is required to supervise the product quality of the process in a timely manner, which is the guarantee of the final quality of the product.

In addition, the quality supervisor will inspect from time to time to correct and deal with the phenomenon of violating the process in a timely manner to ensure the process requirements.

Quality control on the carton production site

According to the purpose of inspection, it can be divided into: control inspection, receiving inspection, quality agency inspection and identification.

On the premise of ensuring the quality of carton products, carton enterprises can set up quality inspection institutions and equip quality inspection personnel according to local conditions. Process inspection generally has the following forms, the first article inspection, the first article inspection is a preventive inspection in the manufacturing process of carton products, suitable for a large number of types. The first article inspection should be inspected by the operator himself and approved by a full-time inspector.

Inspection is a flow inspection of the product quality of the relevant process by inspectors at a certain time interval at the production site. Completion inspection is to inspect a batch of products after processing, mainly referring to the products between each process. The finished product inspection is the last inspection before the corrugated product reaches the user.

　

Physical quality audit of products

The contents of the physical quality audit of carton products are as follows:

The quality defects of the carton are graded, divided into heavy defects and light defects, and detailed inspection items are written. After the actual audit, the quality defect items and audit results should be recorded. The quality defects should be analyzed in a timely manner, the carton quality audit report should be filled in as much detail as possible, the audit results should be reported to the competent leaders and relevant departments, and transmitted and archived as quality information and materials in a timely manner.

 

Quality control at the production site

Create a good production order and environment. Maintaining the cleanliness and hygiene of the production site is also an indispensable condition to ensure the quality of cartons, such as the stacking and transportation of work areas, appliances, products, workers' operating environment, site cleanliness and other factors have an important impact on the production of corrugated box quality, and should be stipulated. Therefore, the corrugated box production site can be effectively controlled by points and points. Its measures can be used: formulate corrugated box production site management standards, and regularly inspect the assessment, site, machines, equipment, raw materials, work-in-progress, stations, and equipment positioning conditions. Effective measures to reduce the damage caused by bumps, scratches, pollution and brutal loading and unloading during carton handling. Semi-finished products and work-in-progress should be labeled: especially the products that come up from the cardboard line are not printed, if they are not listed in the case of similar varieties and specifications, it is easy to cause confusion and errors.

 

Control and corrective actions for non-conforming products

Control and identification of nonconforming products: the corrugated cardboard and cartons of nonconforming products should be identified, and they should not be mixed with qualified cardboard and cartons. It should be isolated, designated in a special area, and not allowed to be used, transferred, or mixed with qualified cardboard cartons without approval. The treatment of nonconforming products can be disposed of in four ways: repair, scrapping, changing accessories, and selling at a reduced price.

Corrective actions for non-conforming products. For batch nonconforming products, it is necessary to fill in the quality accident report form, find out the root cause of the quality accident, and take corresponding measures to effectively control it to avoid the recurrence of similar accidents. At the same time, a special person is designated to be responsible for the implementation of each measure, and supervise and inspect the implementation of these measures to see whether the goal is achieved. And the results of the implementation of the measures and the technical modifications are compiled into documents for archiving.

To grasp the quality of corrugated boxes, it is necessary to start from the quality control of corrugated box production sites, focus on quality prevention, focus on quality prevention, supplemented by quality control, combine prevention and inspection, eliminate the influencing factors of quality in the production process, continuously improve the quality of carton products, reduce the loss of all links, and ultimately improve the economic and social benefits of enterprises.

　　

Carton material classification

Cardboard materials are classified according to the weight per unit area, mainly the following cardboard materials: K paper: 250g/m² A paper: 175g/m² B paper: 125g/m² 7 paper: 200g/m² 8 paper: 260g/m² C paper: 127g/m² core paper: basic 100g/m² large machine 105-110g/m² reinforcing core paper: + paper 115g/m² carton commonly used three layers, five layers, seven layers are used less, each layer is divided into lining paper, corrugated paper, core paper, face paper, lining, Face paper has tea board paper, kraft paper, corrugated paper with core paper, the color and feel of various papers are different, the paper (color, feel) produced by different manufacturers is not the same, the national standard for corrugated boxes is GB6543-86 "corrugated boxes".

The principle of selection of corrugated boxes

When choosing corrugated boxes, we should first take into account the nature, weight, storage and transportation conditions and circulation environment of the product, and secondly, it should be designed according to the design principle of shockproof packaging and corrugated box design methods, and also follow the relevant standards, such as export commodity packaging to meet international standards or foreign requirements, and to go through the relevant tests, so corrugated box packaging selection should generally pay attention to the following two points.

(1) Corrugated model of corrugated cardboard

According to the flute height, it is divided into four categories: A, B, C, E, and the mechanical properties of different corrugated cardboard are also different. Type A corrugated cardboard has the highest plane pressure and high compressive strength; Type B is the opposite; Type C has better plane pressure, vertical pressure, parallel pressure and buffer force.

The thickness between corrugated cardboard, type A is the largest, type C is the second, type B is the smallest, type E is the smallest, because the thickness of the cardboard is easy to process and bend, therefore, the B-shaped corrugated paper is widely used in the packing and shipping of boxes with low requirements for the compressive strength of the box. According to the different mechanical properties of corrugated cardboard, it is better to use A or C type for single-sided corrugated boxes, A, B or B, C for double-sided corrugated boxes, and B type close to the outer surface, which can play an impact resistance. The combination of type A, B or type B and C can improve the physical and mechanical properties of the carton; In terms of printability, both B and C are conducive to printing.

(2) The box shape of the tile carton On the premise of ensuring the quality of the carton, the carton processing materials and packaging costs should be saved as much as possible. Like what. For cartons with the same volume, it is the most material-efficient when the length:width:height is 2:1:2, and the most material-intensive when the ratio is 1:1:1. Therefore, square boxes should be avoided as much as possible. It is also necessary to take into account the utilization rate of the product to the volume of the box, the utilization rate of the volume of the box to the truck and the train car, and the stability of the stacking during storage and transportation.
