Cardboard Box Know How

Cardboard box: is the most widely used packaging products, according to different materials, corrugated cardboard boxes, single cardboard boxes, etc., there are a variety of specifications and models.

Cardboard boxes commonly used are three, five, seven use less, the layers are divided into paper, corrugated paper, core paper, tissue paper, in the paper with tea board paper, 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 tips

Often used as a wrapper or article for the protection of outer products. The size of the carton varies due to the size of the product. The cardboard box is usually "cautious", "scary", "up", "stacking limit", "fear", "moisture", "quality safe" "Can not be trampled" "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 The

Packaging cardboard box as an indispensable part of modern logistics, bear the capacity to protect the product, beautiful and 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 cardboard box testing professional senior engineer, the box for testing and analysis for the container suppliers and box users to provide a fair and scientific test data. 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 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 cardboard box diameter specifications, manufacturing specifications, the relationship between the diameter specifications:

Method of manufacturing dimension of corrugated cardboard box

The size of the cardboard box 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 slitting machine presses out a groove at the press line position, which is the centerline of the groove. The distance between the two lines is the size of the manufacturing. The size of the manufacturing can be converted into inner and outer diameter sizes can be achieved through Table 2, but they also have their own measurement methods.

Corrugated cardboard box in the manufacturing process has a single fight and Shuangpin of the points

Single-fight one-page molding box, generally used for smaller brickboard box; Shuangpin also known as the two-page box, and some cardboard box circumference is too large, had to use two pieces of blanks put together a cardboard box, but sometimes cardboard box Factory in order to use the production process cut down the remaining material, will be used to put together two pieces of a size is not too large cardboard boxes, 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

The manufacture size of the cardboard box joint is determined according to the corrugated layer and the production process level. The single corrugated board is 35 ~ 40mm, the double corrugated board is 45 ~ 50mm, the three corrugated board is 50mm.

Calculate the expansion of the cardboard box area must be taken into account the loss of the wire during the manufacturing process, the size of the wire to determine the number of layers according to the cardboard, generally 20 ~ 40mm.

What is the direct relationship between the strength of the cardboard box and the compression resistance?

Compression generally refers to the static force, the resistance to breaking the static pressure also includes dynamic impact. The former can do the largest accumulation of experiments to determine the latter generally with a certain height of the natural fall and handling the process of frequent accidental impact and transport bumps to choose.

What is the conceptual difference between cardboard box puncture strength and bursting resistance?

Wear strength refers to the cardboard box against the sudden impact of the maximum power can withstand; and burst strength refers to the ability to internal anti-local extrusion; domestic light industry standards have been punctured to cancel the intensity indicators, but the export cardboard box is still required The
