Cardboard boxes commonly used are three, five, seven use less, the layers are divided into paper, corrugated paper, core paper, tissue paper, paper, tissue paper tea board, kraft paper, paper with corrugated paper, The color and feel are not the same, different manufacturers of paper (color, feel) is not the same.
Definition and Tip: Often used as a package or article of goods to protect the outer use of things. The size of the carton is changed by the size of the product. The carton is usually "cautious", "scary", "up", "stacking limit", "fear", "moisture" "Can not trample" "pay attention to fire" "fragile items" "green environment" "hot" "food" "anti-odor" and other patterns or text prompts to remind the user to protect the contents of the goods from harm.
Packaging cardboard box as an indispensable part of modern logistics, bear the capacity to protect the product, aesthetically important responsibility, packaging carton physical performance indicators have become the basis for its quality assessment. Stable working environment conditions to ensure the accuracy and reliability of the test data, and has many years engaged in carton testing professional senior engineer, the box for testing and analysis for the box suppliers and box users to provide fair and scientific test data The TTS (a pass detection) is also a number of well-known enterprises to provide supplier material screening, tender assessment and other projects.
Cardboard box knowledge
Corrugated cardboard is made of paper, paper, paper and corrugated corrugated corrugated paper. According to the needs of commodity packaging, corrugated cardboard can be processed into single-sided corrugated cardboard, three corrugated board, five, seven, eleven layers and other corrugated cardboard.
Different corrugated corrugated shape, the function of the corrugated cardboard is also different. Even if the use of the same quality of tissue and paper, due to the difference between the corrugated shape, the composition of the performance of corrugated cardboard also have some differences. International common corrugated corrugations are divided into four, they are A-type Leng, C-type Leng, B-type Leng and E-type Leng. Their technical indicators and requirements are shown in Table 1. A-type corrugated corrugated cardboard has a good cushioning, a certain degree of flexibility, C-type flute than A-type Leng times. But the stiffness and impact resistance is better than A-type Leng; B-type flute arrangement density, made of corrugated board surface smooth, high pressure, suitable for printing; E-type flute due to thin and dense, but also showed its just strength.
The difference between a container and a non-container is mainly the outer diameter and is closely related to the corrugated type. The following table will be detailed below the carton specifications, manufacturing specifications, the relationship between the diameter specifications:
Method of manufacturing dimension of corrugated box
The size of the carton is the size of the cut box. The dimensions of the manufacture are based on the pressure on the unfolded billet. The indentation roller on the slitter presses a groove in the press line position, which is the centerline of the groove. The distance between the two lines is the size of the manufacturing. The manufacturing dimensions are converted to inner and outer diameter sizes can be made through Table 2, but they also have their own measurement methods.
Corrugated boxes in the manufacturing process have a single fight and Shuangpin of the points
Single fight that is a page molding box, generally used for smaller cartons; Shuangpin also known as the two-box, and some cartons perimeter too much, had to use two pieces of blanket put together a carton, but sometimes carton factory in order to use production The process of cutting down the remaining material, but also with two pieces put together a size is not too large cartons, and sometimes even with four. Two-page box compared with a box, more than a connector, so the size of the two calculations have some minor differences.
Joints and wire back
Carton joint manufacturing size According to the number of corrugated layers and the level of production technology to determine, single corrugated board for the 35 ~ 40mm, double corrugated cardboard for the 45 ~ 50mm, three corrugated board for the 50mm.
Cardboard box technology
Shaped corrugated box is the most form of packaging in today's corrugated box packaging varieties; supermarket goods placed on the shelf, to have a good product display function, and how to quickly and easily open the carton packaging, so that the rapid delivery of goods , And do not need any tools such as scissors or knives, etc., to shout "sesame open the door" carton will open. It sounds very fresh, but this carton has been widely used in foreign supermarkets, and the domestic also has a great demand.
The structure type of sesame open door carton
Sesame open door carton is a new design concept of corrugated box packaging, which is easy to open corrugated boxes. Carton's exterior structure and ordinary corrugated box is no significant difference, the key process is in the corrugated box inside the paste a tear tape station, and in the carton leaving a small mouth, open the carton as long as the small mouth along the tear Cracked tape can be without any tools to open the carton, showing the packaging items.
