How to choose the right packaging box?

With the economic globalization and the development of service industries around the world, China's commodity circulation has also presented a diversified pattern, mainly including commodity distribution, freight forwarding, road transportation, railway transportation, warehousing, and postal services. Because the packaging color box is recyclable and recyclable, it is a green packaging product. Therefore, in the process of commodity circulation, the color box is a more widely used packaging product, and the demand for color boxes in the whole society is increasing.

Color box packaging has more advantages than wooden box packaging, woven bag packaging, cloth bag packaging, and plastic box packaging. It can appear in a variety of forms depending on the packaging product. So when choosing a packaging box, what kind of packaging box is appropriate for consumers? To choose the right packaging box, you should know the following.

1 Color box materials

According to different materials, color boxes can be divided into corrugated color boxes, single-layer cardboard boxes, etc. Corrugated color boxes are most used. Corrugated box is divided into single layer, three layers, five layers, seven layers and eleven layers according to the number of layers of cardboard. Three-layer (single-pit) and five-layer (double-pit) corrugated boxes are the most commonly used. Each layer of cardboard is composed of inner paper, corrugated paper, core paper, and face paper from the inside to the outside. The structure is shown in the figure.

The inside paper is made of teaboard paper, the face paper is made of kraft paper, and the core paper is made of corrugated paper. Tea board paper is soft, off-white, rough surface, low price and light weight. Most of kraft paper is made of pure wood pulp, which has the advantages of pressure resistance, tear resistance, puncture resistance, and good water resistance.

Most domestic corrugated paper is made of semi-chemical pulp or waste paper pulp, and it is also made of mixed pulp. Corrugated waveforms are mainly V-shaped, U-shaped and UV-shaped. V-shaped corrugated paper has a large compressive strength in the plane, but its cushioning performance is poor, and it is not easy to recover from impact deformation. U-shaped corrugated paper is firmly bonded and has a certain elasticity. When impacted by external forces, it is not as fragile as V-shaped, but its compressive strength is not as good as V Corrugated paper; UV-shaped corrugated paper is not only strong in plane compressive strength, but also flexible.

Three and five-layer UV-shaped corrugated boxes are more widely used. The following table shows the types of corrugated boxes that can be determined according to the maximum overall size of the box and the maximum mass of the contents, which can be selected for reference.

The seven-layer and eleven-layer corrugated paperboards are mainly made of packaging boxes for large products such as mechanical and electrical, furniture, motorcycles, etc., with super compressive strength and good cushioning performance.

2 Color box structure


There are many types and types of color boxes. According to international standards, common basic box types are slotted color boxes, nested color boxes, folded color boxes, and combined box color boxes. In addition, there are new non-standard box types.

(1) Slotted color box. Slotted color box is currently the most widely used type of color box, which is formed by combining one or several processed corrugated cardboards by nailing or gluing. The bottom and top flaps form the bottom and lid of the box, that is, the lower and upper flaps, which can prevent items from leaking from the bottom. The advantage of this type of color box is that it can be folded and laid flat during transportation and storage. It has the advantages of small size, convenient use, sealed and dustproof, and clean inside and outside.

(2) Folded box. The nested color box is composed of one or several pieces of processed corrugated cardboard, which is characterized in that the box body and the box cover are separated, and the sleeve is used when used, and the force and compressive strength are better. The advantage of this type of color box is that it is convenient to pack and seal, it is not easy to fall off after the goods are loaded, and the overall strength of the color box is higher than the slotted type. Disadvantages are the large volume of the synthetic type, and the inconvenience of transportation and storage.


(3) Folding color box. Folding color boxes are also called special-shaped color boxes. They are usually formed from a piece of corrugated cardboard through indentation and die cutting, and the bottom, side and box cover of the color box are formed by folding without nailing or gluing. The advantage is that the color box is small after folding, and it is convenient to transport and store.

(4) Combined color box. The combination type box is a combination of two or more basic box types, which can be combined according to the characteristics of the goods and packaging requirements.

(5) New non-standard color box. The new non-standard color boxes are mainly roll-type color boxes, separate color boxes and triangular column color boxes. The roll-up color box is a color box blank that is made in a color box factory, and then the user uses an automatic packaging machine to put the contents on the color box blank and then rolls it into a box. The advantage of the roll-up color box is that less materials are used, the color box and the contents are closely attached, and high-speed automation can also be realized. The separated color box can be combined with various auxiliary materials to combine the small box type on the basis of the traditional standard box type. In the distribution process, it can be divided into two or more. It mainly solves the problem between mass production and small batch sales. contradiction. The triangular column corrugated box is formed by one box and the corner lining. The four corners of the corrugated box form a triangular column or a right-angle column structure, thereby improving the compressive strength by 20% to 50%. There are two types of triangle-shaped color boxes: tray type and sealed type, and there are various box types to choose from.

Regardless of whether it is a standard type or a new non-standard type, commonly used sealing methods include adhesive sealing, tape sealing, interlocking sealing, and U-shaped nail sealing.

3 Quality inspection items of color box


(1) Appearance inspection. The pattern and text printed on the color box must be clear, correct, consistent in shades, and accurate in position.

The single corrugated box is not more than 12mm in width; the double corrugated box is not more than 17mm. The broken line is centered, and there must be no breaks, heavy lines, cracks and other defects, and there must not be extra creasing lines on the box. There should be no obvious burr on the edge of the knife, and the damage of the paper at the cutting edge of the knife should not exceed 8mm from the edge of the box, and the diameter of the hole at the corner of the box should not exceed 5mm. For box nails, it is necessary to choose a low-carbon steel flat wire with a plating layer, and it must not have defects such as rust spots, peeling, and cracks. The spacing should be uniform. The distance between single nails is not more than 55mm, and the distance between double nails is not more than 75mm. The color box is supported and formed. After the flap is opened and closed for three consecutive times at 270 °, it is required that there should be no cracks in the top and bottom paper. The width of the overlapping tongue is 35mm-50mm, and the box nails should be nailed along the centerline of the overlapping tongue, arranged neatly, and the deflection should not exceed 5mm. The width of the adhesive overlap tongue is not less than 30mm. The adhesive should be applied evenly and sufficiently without spilling. Box paper is not allowed to be spliced, lack of material, wrinkles, corrugations, or through glue. The paper splicing in the color box shall not be more than two times, and the distance from the splicing head to the indentation line of the shake cover shall not be less than 30mm. The moisture content of corrugated box should be controlled within 8% ~ 16%. Inside the box, the maximum deviation of the single limit should be controlled within ﹣2mm-5mm.

(2) Performance parameters. Color box performance parameters mainly include side pressure strength, burst strength, puncture strength, and compressive strength. Only when these main performance parameters meet the national standards, the color box is considered qualified. That is, a batch of qualified color boxes should be given the performance parameter values for consumers' reference.
