Cardboard Box: is the most widely used packaging products, according to different materials, there are corrugated box, single-layer carton, and various specifications and models.
Carton is the commonly used three layer, five layer, use less, in each layer is divided into paper, corrugated paper, core paper, glossy paper, and paper have tea plate paper, kraft paper, core paper with corrugated paper, all kinds of paper color and feel is different, different manufacturer production of paper (color, handle) is different also.
Definitions and tips
A parcel or article commonly used as a commodity to protect the outer use of the product. Carton size change, due to the size of the goods the cartons there are usually "handle with care", "keep dry", "up" and "stacking limit", "fear of the sun", "moistureproof" "quality safety" "no roll" "on" "pay attention to the fire" "breakable" "green environment" "can't stand the heat" "food" "anti odor," and so on a variety of patterns or text prompt, alert the user, in order to protect the built-in items from harm.
Packaging carton as an indispensable part of modern logistics, bear the important responsibility of RongZhuang, protection products, beautiful, and the physical properties of the packaging carton index became the basis of its quality evaluation. Stable work environment conditions to ensure the veracity and reliability of the test data, and has many years engaged in carton testing professional senior engineer, test analysis for packaging, users and suppliers of packaging packaging to provide fair and scientific test data. TTS (one check) also provides supplier material screening, bidding evaluation and other works for well-known enterprises.
The special-shaped corrugated box is the most varied packaging variety in corrugated carton packaging. Directly on the goods in the supermarket shelves, want to have good product display function, and how fast, easy to open the cartons, do the goods quickly take put, and does not require any tools such as scissors or a knife, she shout a loud "open sesame" carton is opened. It sounds fresh, but the cartons are already widely used in supermarkets abroad and there is a great demand in the country.
The structure of the sesame open box
Sesame open box is a new design concept of corrugated box packaging, namely easy to open corrugated box. Carton of exterior structure with the ordinary corrugated carton, there is no obvious difference between its key technology is inside the corrugated carton paste has a torn rubber belt, and on the outside of the carton with a small mouth, opened the carton as long as the small mouth along the tear tape can open the cartons without any tools, packaging items.
Introduction to processing technology
The necessity of tearing
Easy to open the corrugated carton production process compared with common carton production process, adding in a tear of the surface of the corrugated paper box pasting high-performance, self-adhesive tape, as well as the tear tape design a corresponding tear, so facilitate users don't need to use external forces can open the carton, and tore his mouth is beautiful, do not affect commodity exhibition effect.
The tear adhesive tape used for easy opening of the carton is made of a modified tension polypropylene with natural rubber adhesive. Natural rubber adhesive provides excellent initial adhesion, excellent anti-tear resistance and strong adhesion to different materials. The tearing tape used in corrugated box production is usually scrolls. Depending on the width of the torn adhesive tape, the width ranges from 3mm to 20mm, and the length of a roll of tape is about 40,000 meters. Long scroll packaging can reduce the number of new scrolls, which can improve production efficiency.
Carton production process
Design determines the final effect of the product
It is very important to design the carton products, otherwise it will be difficult to meet the customer's requirements, and may return the goods, causing significant losses to the enterprises.
I think the Marketing Department should send all the information of the customer to the process design department after receiving the order. These include layout requirements, specification size, box structure, internal loading and weight, stack number and other related content. After the design of the design department, it can be reached to the manufacturing department to complete the product realization.
1) calculate the maximum stacking load Ps that can be borne by the bottom carton
Namely, Ps= (nmax-1) · G, where Nmax is the maximum heap number, and G is the inner and box weight.
2) select the appropriate safety factor K
According to the requirements of SN/t0262-93 export packaging of corrugated carton inspection procedures, K=1.6 when the storage period is less than 30 days; 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 usually takes more than 3. However, the safety factor is too large, the index of raw materials is relatively high, the price of paper will rise significantly, resulting in increasing cost and unfavorable to market development. Moreover, if the safety factor is too large, there will be a mass excess, a small coefficient, and a collapse box and other quality problems. Therefore, according to the actual requirements of the customer, select the appropriate safety factor.
3) calculate the maximum compressive strength value (P) according to the safety factor
The P = k. Ps
4) according to the formula of Kelicutt, choose the appropriate combination of paper and paper
So Px times F is equal to P.
So Px= P/F, where F is the constant associated with the circumference of the box and the corrugated type, which is obtained by looking up the table. Px is the strength value of the integrated ring of corrugated board, 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 calculated to achieve the purpose of reasonable matching of paper.
2. Process control is the guarantee of product realization
The design of the technical department can be carried out well, and each process is essential to the strict execution of the standard. Therefore, the monitor of the process is required to timely supervise the product quality of the process, which is the guarantee of the final quality of the product.
In addition, the quality supervisors shall inspect the products on a regular basis, timely correct and deal with the violation of the process, so as to ensure the strict implementation of the process.
